characteristics of fabric. Such technology may reduce dye concentration in waste-water effluents from textile sector and ultimately become energy
efficient and cost effective. Plasma technology has proven to impart enhanced dye exhaustion, dye penetration, dyeing in shorter time with minimal of
chemical auxiliaries and energy usage. The potential attributes of plasma on textile dyeing is discussed in this article..
The Influence of Cationization on the Dyeing Performance of Cotton Fabrics wi...IJERA Editor
This document discusses how cationization, or chemical modification using cationic agents, can improve the dyeability of cotton fabrics with direct dyes. The author cationized cotton fabrics using different concentrations of a cationic agent and measured the nitrogen content, which increased with higher cationic agent concentration. Cationization was optimized based on factors like pH, temperature, and time. Dyeing cationized cotton with two direct dyes resulted in higher color strength values than untreated cotton. Cationization allows direct dyes to be used at lower concentrations, reducing dye and water usage and wastewater pollution.
Lyocell microfibre fabrics were produced using rapier weaving machine, which is to be used as inner layer while developing the Multilayered Technical Tecxtiles. The lyocell microfibre fabric has been treated with plasma using low pressure Oxygen. Then the plasma treated and untreated fabrics were dyed using reactive dyes. The dyed lyocell fabrics of plasma treated and untreated were tested for the comfort properties such as Wickablity, Air Permeablilty and Water Vapour Permeablilty. The results of the study confirmed that there is a significant improvments in Wickablilty and Air permeablilty of plasma treated fabrics which are essential characteristics for inner layer of the Multilayered Technical Textiles. The significant improvements due to new porus in the treated fabrics allow more air to penterate and also to increase the Wickablilty. Where as the Water Vapour Permeablilty characteristics of the untreated fabric have better results than plasma treated fabrics due to new etching on the surface of the treated fabrics which retain more vapour than untreated fabrics. The Plasma treated lyocell fabric can be used as inner layer for the development of Multilayered Technical Textiles.
This presentation summarizes the use of plasma technology in textile processing. It discusses how plasma is created through heating and ionizing gas, and its classification. The presentation then outlines various plasma systems used in textiles and how plasma works to modify fabric surfaces at a nano scale. Specific textile applications of plasma technology discussed include desizing, dyeing, improving wettability and printability. The presentation notes the advantages of plasma treatment as being more environmentally friendly and providing properties like abrasion resistance and faster dyeing. It concludes that plasma technology is an interesting alternative to conventional wet processing methods.
Plasma finishing can improve the hydrophilicity of polyester fabrics. Plasma treatment introduces functional groups like carboxylic acids onto fabric surfaces through chain scission and re-deposition, making fabrics more wettable. Treatment time and power affect moisture absorption, with longer treatments and higher power increasing hydrophilicity. While oxygen and water plasmas increase wettability, the effect decreases over time. Graft polymerization provides more durable hydrophilicity. Plasma is advantageous for being environmentally friendly, requiring no chemicals or additional drying, and not damaging fabrics. The textile industry has growing interest in plasma finishing as a novel technology.

Application of Plasma Technology for Coated Textileijsrd.com
More than 99% of the visible matter in the universe is in the plasma state. It can be seen in its natural form on earth as lightning or as polar light in the Arctic and Antarctic. Plasma was first discovered by Irving Langmuir in 1928. Plasma technology is based on a simple physical principle. Matter changes its state when energy is supplied to it: solids become liquid, and liquids become gaseous. If even more energy is supplied to a gas, it is ionized and goes into the energy-rich plasma state, the fourth state of matter.
FLAMMABILITY CHARACTERISTICS OF CHEMICAL TREATED WOVEN HEMP FABRICmsejjournal
Woven hemp fabric was treated with sodium hydroxide, commercial flame retardant chemical, and
combination of both to increase its fire-retardant properties. Treatments of fire-retardant changed the
properties of woven hemp fabric such as increased its fabric shrinkage and density of fibres which ranges
from 0.67 to 5% and 1.43 to 1.53 g/cm3
respectively. After the treatment, the fire retardancy of the fabric
increased tremendously which was observed by the burning, thermogravimetry and limiting oxygen index
tests. Some of the samples were not burnt when exposed to flame source and the burning rate needed to be
measured under exaggeration of flame at longer time. The limiting oxygen index value increased from 18.6
to 51 after the treatments which explained the scenario happened in the burning tests. Nevertheless, its
mechanical properties decreased slightly that ranges from 18 to 32% and 23 to 39% for warp and weft

Methane Purification Using PVC Membrane: Preparation, Characterization and Pe...journal ijrtem
ABSTRACT : Methane (CH4) gas stands as one of the most prevalent gaseous in the air. Global methane emissions from landfill are estimated to be between 30 and 70 million tonnes each year. Methane originating from landfill is vastly found in developed and populated countries, where the levels of waste tend to be the highest. A study was done at Kampung Sg. Ikan Landfill in Kuala Terengganu, Malaysia. In this study, wastes were segregated according to specific types of wastes, such as 3D plastics (bottles), 2D plastic (food wrappers), glasses, food wastes and so on. From this study, it is found that food waste contributes the highest collection of waste for the past three weeks of segregation activities in the landfill. The data and studies from the landfill motivated a method was needed to separate gas from wastes using a cheap and effective polymer and hence, usage of PVC was used to separate CH4 gas from the CO2/CH4 mixture. The PVC membrane is produced by the combination of Polyvinyl Chloride (PVC) and N-Methyl-2-pyrrolidone, (NMP) via dry/wet phase inversion technique. The production of PVC membrane is expected to improve the characteristics of the polymeric membrane, such as the permeability, selectivity and the pore size. PVC is introduced with ratio of NMP (solvent): PVC, 82:18, 80:20, 77:23, and 75:25. This ratio enables the desired selectivity and permeability of CO2/CH4 gas separation. The PVC membrane with composition 77:23 was the highest performance in terms of selectivity at 2 bars. The SEM images of the surface morphology were included with the pore diameter ranging from 9.87μm to 28.7μm.
Effect of titanium dioxide treatment on the properties of 100% cotton knitted...Elias Khalil (ইলিয়াস খলিল)
Titanium dioxide (TiO2) is a white, water insoluble pigment. It is used in paints, plastics, foods, pharmaceuticals and cosmetics. Its main application on textile materials as an ultraviolet ray protecting agents. Titanium dioxide can reflect, scatter or absorb ultraviolet ray. Besides Titanium dioxide also modify the properties of fabrics. In previous research, titanium dioxide was applied mainly by padding mangle method. This paper presents an approach to observe the effect of titanium dioxide treatment 100% cotton knitted (plain jersey) fabric applied by exhaustion method followed by curing and washing. The treated fabrics were then analyzed by Scanning Electron Microscope (SEM) and the tensile strength, pH value and absorbency of the treated and untreated fabrics were checked. It is found that titanium dioxide impairs the better hand feel and absorbency (wetting time) of all treated fabrics increased gradually than untreated fabrics. The treatment increases the strength and keeps the pH of the fabric in acidic medium.
IRJET- Fabrication of Poly(Methacrylic Acid) Functionalized Cellulosic Fibers...IRJET Journal
This document summarizes research on functionalizing viscose cellulosic fibers with poly(methacrylic acid) to impart cationic dye uptake capacity for textile applications. Key findings include:
1) Viscose fibers were modified through in-situ polymerization and grafting of methacrylic acid to introduce anionic carboxyl groups onto the fiber surface.
2) The degree of cationic dye uptake from basic dyes increased with higher grafting levels of poly(methacrylic acid) onto the fibers, as measured by higher K/S values.
3) Additional treatment with tannic acid and potassium antimony tartrate further improved dye uptake and wash fastness properties for fibers with
Regards to evolution of the desirable properties and chemical structure in high performance of gas separation by membrane, mixed matrix membranes (MMMs) as one of types, need to carefully design and control to realize high efficiency. This research investigates the role of main parameters in the fabrication and performance analysis of MMMs prepared through blending of alumina nano particles (Al2O3) and poly (4-methyl-1-pentyne) known as PMP with various weight percentages of alumina nano-particles in PMP precursor. Precursor and resultant MMMs were characterized using TGA and SEM techniques. SEM images demonstrated the proper dispersion of Al2O3 particles in precursor matrix. Results indicated that the microstructure of the precursor, blend composition and the content of nano particles play an important role in gas transport properties of the resulting MMMs. The influence of the percentage of alumina nano particles used in the precursor matrix on the CO2 and N2 permeability and CO2/N2 ideal selectivity of the MMMs illustrated in a trend. Using higher alumina content resulted in membranes with higher permeability and ideal selectivity. The highest rate of CO2 and N2 permeability could be obtained from PMP-alumina with loading of 30 wt.% alumina (PMP30) at 10 bar. Furthermore, these results suggest that PMP30 MMMs (at operating pressure of 8 bar) are exceptional candidates for the CO2/N2 separation, offering enhanced gas pair selectivity in the range of 4.5-5 depending on the operating pressure. The results of this research revealed that high-performance gas separation by MMMs can be realized through adopting a judicious combination of blending and dispersing technique.

Melt flow properties and crystallization temperatures were analyzed for the different PP/kaolinite compositions. The crystallization temperature increase with kaolinite content indicates kaolinite acts as a nucleating agent for PP crystallization. Fibers, filaments, and 3D printed specimens were produced to characterize the
1) Solid state NMR spectroscopy can distinguish between leathers tanned with different vegetable tanning agents based on characteristic spectral fingerprints. Condensed tannins from mimosa and quebracho leave distinct fingerprints in leather spectra related to their chemical structures.
2) Hydrolyzable tannins from chestnut and tara also leave identifiable fingerprints in leather spectra. NMR can differentiate between leathers tanned with condensed versus hydrolyzable tannins.
3) Chromium tanned leather shows selective disappearance of collagen signals, including from acidic aspartyl and glutamyl residues likely bound to chromium. This indicates chromium binding to acidic residues in the collagen matrix.
ATC13 Full Manuscript - Engr Sadam Hussain- Final versionSadam Hussain
Increasing worldwide interest towards natural and sustainable products has driven the textile processing industry to use dyes and chemicals obtained directly from natural resources. Also, textile processors and researchers have been exploring the emerging technologies such as using ultrasonic energy, plasma, supercritical carbon dioxide, microwave and electrochemical methods for processing. In the same context, this work was undertaken to develop a method for dyeing of cotton fabric with natural dye extracted from marigold flower petals using ultrasonic energy. The aqueous extraction of natural dye from marigold flower petals was optimized for temperature and time. The resulting extract was used to further optimize its dyeing conditions on cotton fabric by ultrasonic and conventional exhaust dyeing methods. The effect of pre-mordanting with alum was also studied. Generally, all dyed samples were built with either yellow, golden yellow or tan colours (depending on varying dyeing parameters and conditions). It was found that the optimum aqueous extraction can produce strong colour yields with K/S value up to 5. Whereas, ultrasonic dyeing produced better colour yields comparing to conventional exhaust dyeing method. The colourfastness testing of optimum dyed fabric samples was also carried out for rubbing, washing and light exposure. The overall colourfastness of the dyed samples was acceptable except washing fastness of the sample dyed by conventional exhaust method without mordanting. However, washing fastness was considerably improved with pre-mordanting and further improved by ultrasonic dyeing method. Further, the rubbing and light fastness results were very good in case of pre-mordanting and ultrasonic dyeing method.

1. The physico-chemical aspect of the dyeing process describes how dye molecules penetrate and diffuse into fibers over time through various stages.
2. When dyeing reaches equilibrium, dye is distributed between the dye bath and textile material through processes like convection, molecular diffusion, adsorption, and diffusion into and bonding within fibers.
3. Key stages include dye dispersing in the bath, diffusing through liquid layers to the fiber surface, passing the electrical double layer, absorbing and diffusing into the fiber, and physically or chemically bonding within the fiber.
Textile finishing refers to processes performed on fabrics after dyeing to improve properties like appearance, performance, and feel. There are two main types of finishing: chemical finishing which uses chemicals and water, and mechanical finishing which uses techniques like calendaring without chemicals. Finishing aims to enhance fabric qualities, increase durability, impart new properties like flame resistance, and adapt fabrics for specific end uses. Processes can be classified as temporary or durable, and include techniques like brushing, compacting, resin treatment, and more. Careful consideration of factors like fiber type is needed to develop effective chemical formulations for finishing.
Plasma technology application in textile assignment.Md. Nazrul Islam
Plasma technology can be used to modify textile surfaces through physical and chemical mechanisms. Physically, ion bombardment changes surface topography and increases roughness and adhesion. Chemically, reactive free radicals generated by plasma decrease activation energy for chemical reactions, allowing for material removal. Plasma treatment can improve properties like mechanical strength, electrical conductivity, hydrophilicity, dyeability, printability, and adhesion. It can also introduce desired functional groups and deposit coatings. Plasma activation of textile surfaces has wide applications including softening, shrink resistance, antistatic finishes, dyeing, bonding, water/oil repellency, sizing removal, antimicrobial finishes, and more.
This document discusses plasma technology and its applications in textiles. It begins with an introduction to plasma and its classification. It then explains how low temperature plasma is generated and the working pressures used. The document outlines several textile applications of plasma including desizing, wettability enhancement, printability and dyeability improvement.

The highest rate of CO2 and N2 permeability could be obtained from PMP-alumina with loading of 30 wt.% alumina (PMP30) at 10 bar. Furthermore, these results suggest that PMP30 MMMs (at operating pressure of 8 bar) are exceptional candidates for the CO2/N2 separation, offering enhanced gas pair selectivity in the range of 4.5-5 depending on the operating pressure. The results of this research revealed that high-performance gas separation by MMMs can be realized through adopting a judicious combination of blending and dispersing technique.

Kaolinite/Polypropylene Nanocomposites. Part 1: CompoundingIRJET Journal
This document summarizes research on producing and analyzing kaolinite/polypropylene nanocomposites. Three types of polypropylene (PP) and kaolinite powder were compounded at various formulations from 0-30% kaolinite content using a twin-screw extruder. The compounded pellets were then extruded to produce fibers for further drawing or filaments for 3D printing. Melt flow properties and crystallization temperatures were analyzed for the different PP/kaolinite compositions. The crystallization temperature increase with kaolinite content indicates kaolinite acts as a nucleating agent for PP crystallization. Fibers, filaments, and 3D printed specimens were produced to characterize the
1) Solid state NMR spectroscopy can distinguish between leathers tanned with different vegetable tanning agents based on characteristic spectral fingerprints. Condensed tannins from mimosa and quebracho leave distinct fingerprints in leather spectra related to their chemical structures.
2) Hydrolyzable tannins from chestnut and tara also leave identifiable fingerprints in leather spectra. NMR can differentiate between leathers tanned with condensed versus hydrolyzable tannins.
3) Chromium tanned leather shows selective disappearance of collagen signals, including from acidic aspartyl and glutamyl residues likely bound to chromium. This indicates chromium binding to acidic residues in the collagen matrix.

Increasing worldwide interest towards natural and sustainable products has driven the textile processing industry to use dyes and chemicals obtained directly from natural resources. Also, textile processors and researchers have been exploring the emerging technologies such as using ultrasonic energy, plasma, supercritical carbon dioxide, microwave and electrochemical methods for processing. In the same context, this work was undertaken to develop a method for dyeing of cotton fabric with natural dye extracted from marigold flower petals using ultrasonic energy. The aqueous extraction of natural dye from marigold flower petals was optimized for temperature and time. The resulting extract was used to further optimize its dyeing conditions on cotton fabric by ultrasonic and conventional exhaust dyeing methods. The effect of pre-mordanting with alum was also studied. Generally, all dyed samples were built with either yellow, golden yellow or tan colours (depending on varying dyeing parameters and conditions). It was found that the optimum aqueous extraction can produce strong colour yields with K/S value up to 5. Whereas, ultrasonic dyeing produced better colour yields comparing to conventional exhaust dyeing method. The colourfastness testing of optimum dyed fabric samples was also carried out for rubbing, washing and light exposure. The overall colourfastness of the dyed samples was acceptable except washing fastness of the sample dyed by conventional exhaust method without mordanting. However, washing fastness was considerably improved with pre-mordanting and further improved by ultrasonic dyeing method. Further, the rubbing and light fastness results were very good in case of pre-mordanting and ultrasonic dyeing method.

1. The physico-chemical aspect of the dyeing process describes how dye molecules penetrate and diffuse into fibers over time through various stages.
2. When dyeing reaches equilibrium, dye is distributed between the dye bath and textile material through processes like convection, molecular diffusion, adsorption, and diffusion into and bonding within fibers.
3. Key stages include dye dispersing in the bath, diffusing through liquid layers to the fiber surface, passing the electrical double layer, absorbing and diffusing into the fiber, and physically or chemically bonding within the fiber.
Textile finishing refers to processes performed on fabrics after dyeing to improve properties like appearance, performance, and feel. There are two main types of finishing: chemical finishing which uses chemicals and water, and mechanical finishing which uses techniques like calendaring without chemicals. Finishing aims to enhance fabric qualities, increase durability, impart new properties like flame resistance, and adapt fabrics for specific end uses. Processes can be classified as temporary or durable, and include techniques like brushing, compacting, resin treatment, and more. Careful consideration of factors like fiber type is needed to develop effective chemical formulations for finishing.
Plasma technology application in textile assignment.Md. Nazrul Islam
Plasma technology can be used to modify textile surfaces through physical and chemical mechanisms. Physically, ion bombardment changes surface topography and increases roughness and adhesion. Chemically, reactive free radicals generated by plasma decrease activation energy for chemical reactions, allowing for material removal. Plasma treatment can improve properties like mechanical strength, electrical conductivity, hydrophilicity, dyeability, printability, and adhesion. It can also introduce desired functional groups and deposit coatings. Plasma activation of textile surfaces has wide applications including softening, shrink resistance, antistatic finishes, dyeing, bonding, water/oil repellency, sizing removal, antimicrobial finishes, and more.
This document discusses plasma technology and its applications in textiles. It begins with an introduction to plasma and its classification. It then explains how low temperature plasma is generated and the working pressures used. The document outlines several textile applications of plasma including desizing, wettability enhancement, printability and dyeability improvement. It discusses the advantages of plasma treatment for textiles as well as some disadvantages.
Simultaneous Acid Dyeing and Modified DMDHEU Finishing of Cotton Fabrics for ...IRJET Journal
This document discusses a study on simultaneously dyeing and finishing cotton fabrics with acid dyes and modified DMDHEU resin. The goal is to reduce energy consumption, time, and costs compared to conventional separate dyeing and finishing processes. Cotton fabrics were treated with varying concentrations of acid dye and modified DMDHEU using a pad-dry-cure method. The treated fabrics were evaluated for color strength, crease recovery angle, tensile strength, weight add-on, and fastness properties. The results showed improved color strength compared to separately dyed fabrics. Crease recovery angles were comparable to conventional processes. This simultaneous process offers advantages of reduced energy, time, and production costs while providing sustainable textile processing.
Antimicrobial finishing of polyester fabric using atmospheric pressureAakash Singh
This document describes a process for imparting antimicrobial properties to polyester fabric using atmospheric plasma treatment and subsequent chemical modifications. The process involves mild scouring of the fabric, surface hydrolysis using NaOH, plasma treatment using a helium-oxygen gas mixture, graft copolymerization with GMA, and treatment with chitosan modified with GTMAC. Characterization techniques like FTIR, SEM, and tensile testing are used to analyze the treated fabrics. The conclusion is that atmospheric plasma treatment is suitable for fabric finishing and does not significantly impact bulk or tensile properties.
This document summarizes research on using a carbon dioxide laser to fade the color of cotton/kapok indigo denim fabric. Key findings include:
1) Laser treatment successfully faded the color of the cotton/kapok fabric, reducing the K/S value, while having little impact on thickness or permeability.
2) Tensile strength of the cotton/kapok fabric decreased with laser treatment, likely because the internal air of hollow kapok fibers was squeezed out.
3) Increasing laser power or decreasing speed led to greater reductions in both K/S values and strength, but negligible changes in thickness and permeability.

Using sludge in concrete provides advantages like reducing land and groundwater pollution compared to disposal. Further work could explore using sludge ash in concrete after burning the organic matter.
Application of Plasma finishing on Cotton FabricIJERA Editor
“Plasma” word is derived from the Greek and referring to the “something molded or fabricated”. Plasma treatments are gaining popularity in the textile industry. Plasma treatment has to be controlled carefully to avoid detrimental action of the plasma onto the substrate. Plasma surface treatments show distinct advantages, because they are able to modify the surface properties of inert materials, sometimes with environment friendly devices. For fabrics, cold plasma treatments require the development of reliable and large systems. Application of “Plasma Technology” in chemical processing of textiles is one of the revolutionary ways to boost the textile wet processing right from pre-treatments to finishing.
Wrinkle free resin finishing is a process to apply chemical resin onto fabrics functioning crosslinking between hydrogen bonds in order to enhance stability, on other words, fabrics are prevent to wrinkling. The ability of a fabric to recover to a definite degree is called crease recovery of the fabric.Tendency of fabrics made by cellulose, regenerated cellulose and blends with synthetic fibers to wrinkle after washing, tumble drying and wearing are higher. Today everybody wishes for that his/her dress retains just ironed shape. Wrinkle free finishes provide wrinkle free and soft look fabric. Wrinkle free finishes are broadly used in the textile industry to impart wrinkle-resistance to cellulosic materials such as cotton fabric.
This document summarizes a research study that investigated applying polyacrylamide softeners to cotton and cotton/polyester fabrics to enhance surface smoothness and quality properties.

Evaluation on a Promising Natural Cellulose Fiber- Calotropis Gigantea FiberCrimsonpublishersTTEFT
Calotropis gigantea fiber is a kind of natural cellulose fiber that regains increasing attention nowadays, thus it is evaluated here aiming to replace cotton or kapok fibers to some extent. New discoveries are found about its morphological structure, indicating that it has sharper, closed tip and coarser, open end, and that it usually has 4-6 grooves along its longitudinal axis, with fully distributed microvillus on its surface. The FTIR spectrum shows the fiber mainly contain cellulose, lignin and hemi-cellulose component. X-ray diffraction analysis shows that the fiber has higher crystallinity in comparison with kapok fiber. In term of breaking strength, the fiber is obvious lower than cotton fiber and a little higher than kapok fiber. Furthermore, the fiber has good water absorbing and releasing capability, implying it has excellent water transmissivity.
Green Processing of Dyes: Influence on Physico- Mechanical Properties, Color ...CrimsonpublishersTTEFT
The present article describes the role of dyes in enhancing the various properties of fibers along with their brief history and the recent methodologies used to minimize their negative impact on environmental safety. Since primitive age, natural dyes were used as coloring agents in textile industry. Later, in nineteenth century, synthetic dyes due to their high dyeability, varying shades ability, and comparatively low cost have replaced natural dyes. However, environmental concerns like water and marine pollutions forced the textile industry to develop new methodologies for the utilization of natural dyes with improved properties. Literature reveals that the use of new and advanced techniques have enhanced the dyeability, strength, softness, antimicrobial and other properties of textiles. These are mainly classified in to; a) the chemical modifications of natural dyes, and b) the surface modification of fabrics. In addition to these, the negative and positive impacts of these methods along with the future scope of research have also been discussed.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
