As we know polyester is a synthetic fiber and has
more crystalline structure than natural fibers. In continuous
dyeing of polyester by pad-Thermosol process, there are many
advantages such as bulk production, low-cost, good efficiency etc.
But during dyeing process there is a severe problem occurs that
is dye migration .in order to control the dye migration different
migration inhibitors are used in this project. Both natural and
synthetic migration inhibitors are applied on the 100% polyester
fabric in order to compare that which migration inhibitor hives
better results on the pad-Thermosol process.
After comparing the different properties of the both migration
inhibitors the synthetic inhibitors found more efficient then the
natural one. The following tests were conducted during project:
Migration test, tensile strength, color strength, bending length,
light fatness.
Synthetic migration inhibitors gives better results for the tests
which were conducted .but there is a problem that the synthetic
migration inhibitors are not environmental friendly and they are
costly then natural migration inhibitors.

Sustainable dyeing process to cope with Industry 4.0Emran Ali
Value addition for textiles is an important process and it is required for all products including yarn, fabric, garment, fashion apparel, floor covering, and the majority of technical textile. For each textile processing, the processor used enormous amounts of chemicals and water in order to attain the desired result. After processing the residual processed chemicals and waters are treated with effluent treatment and discharged into the mainstream. The amount of residual unfixed dyes, metal compounds, formaldehyde-based dye-fixing agents, hydrocarbon-based softeners, and all types of dye-bath auxiliaries, as well as their degradation nature against the environment, are the deciding factors for its sustainability. There are many factors influencing the overall efficiency or value addition of a textile product, which play an important role in its sustainability.
ADSORPTION OF CONGO RED DYE AND METHYLENE BLUE DYE USING ORANGE PEEL AS AN A...Ajay Singh
To reduce the concentration of the dye activated charcoal is used as an adsorbent but due to the high cost of activated charcoal, the purpose of my project was to find an alternative low-cost adsorbent.
The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different processes in dyeing and finishing processes. The low-cost, easily available naturally prepared coagulants like moringa seed powder, maize seed powder, green bean powder and tamarind seed powder as an alternative to recent expensive coagulant methods for reactive dye removal has been investigated in this study. Various process parameters like pH, coagulant dose, flocculation time and also its optimization were exploited. The maximum percentage color removal was found to be 80.26, 78.30, 74.04, 72.68 and 70.53 for moringa, corn, aluminium sulphate, green bean and tamarind, respectively, at pH 9.0, coagulant dose of 30 mgL-1, flocculation time 120 min. The sludge volume index (SVI) was calculated for these parameters including process optimization. Natural coagulants were better coagulant than aluminium sulphate which corresponds to color removal and sludge volume index.

Water is vital for the entire aspects of life and also an important feature that defines our planet. Deprived water quality due to poor wastewater management is a crisis faced by every country in the world. This crisis affects directly and indirectly on our biological diversity, disturbing the entire ecosystem that act as our life support system (Corcoran et al, 2010). There are many factors affecting the aforementioned crisis and textile industry effluent is one of major contributor among other industrial wastewater (Verma, Dash, & Bhunia, 2012). Recent literature acknowledged dyeing and finishing processes is the main aforementioned contributor (Khandegar & Saroha, 2013).

Effect of Alternative Scouring Agents on Dyeing Properties of Cotton/Polyeste...IOSR Journals
This research comprises of six alternative agents ((NH4)2C2O4, liquid NH3, CH3COOH, NH4OH, (COOH) 2, CH3CH2OH) at various concentrations of 1-5% used as scouring agents with NaOH as control on cotton/polyester blend fabric. The samples were bleached, mercerized and dyed. The suitability and reliability of the agents were evaluated for dyeing properties of the treated fabric. Water imbibing properties of the treated fabric, was investigated. The experimental results showed that the percentage exhaustion of indigo dye on the treated fabric were wonderful with values far above average (86.8-62.6%) except for 1% (NH4)2C2O4 that recorded slightly below average (49.7%). 2% liquid NH3 ranked the highest. The wash fastness is another interesting results where only 1-5% liquid NH3, 2% and 4% (NH4)2C2O4 that gave a grey scale rating for wash fastness of 4 (very good). The other alternative agents strongly competed at various concentrations with the control which revealed a rating of 5 (excellent wash fastness). 4% (NH4)2C2O4 scoured fabrics recorded the highest water of imbibitions (2.9 g). This implies that the alternative agents are suitable and reliable as impurity-removing (scouring) agents. The alternative agents improved the dyeing and water imbibing properties of the treated fabric far better than the control. Therefore could be employed in the textile industry.
Isolation of self Printing paste from Plant Seeds and Its Application in Simu...IJERA Editor
Printing pastes containing eco-friendly galactomannan gum and safety natural dye were isolated simultaneously
in one step process from tara plant seeds using sodium hydroxide solution. The effect of concentrations of
sodium hydroxide on the rheological properties of the isolated printing pastes were thoroughly investigated.
Technological evaluation of the obtained pastes to act as screen printing paste and burn-out style paste to be
used in printing five different blends as well as pure wool was achieved. The results were evaluated via
measuring the % loss in weight, K/S of the coloured area and tensile strength for the printed area.
The results obtained reviles that all the isolated pastes are characterized by non-Newtonian pseudoplastic
behaviour, and its apparent viscosity depends on the concentration of sodium hydroxide and also on the time of
storing. The prepared pastes could be used successfully as a screen printing paste and burn-out paste
simultaneously. The % loss in weight increases by increasing sodium hydroxide concentration and/or the portion
of wool in the blend. The K/S of the printed area depends on the nature of the component of the blend and
higher on protenic fabrics than that of cellulosic.
Unique colour and attractive texture could be achieved using the current technique. It is also found that as the
concentration of sodium hydroxide increases, the % loss in tensile strength increases specially for woolen
blends, however the decreases is not high and satisfactory for industrial application.

Investigation on effluent characteristics of organic cotton fabric dyeing wit...Elias Khalil (ইলিয়াস খলিল)
Environmental sustainability is the major concern in the age of modern world. For textile and apparel sector, this has been a burning issue for many related concerned bodies. The pretreatment and dyeing process of greige fabrics results in large volume of effluents that has harmful effect on environment. In this study, the ecological parameters of the effluents obtained from scouring and dyeing of 100% organic cotton single jersey knitted fabrics with environmentally low impact Remazol series reactive dyes adopting exhaust dyeing method was investigated. The effluents collected for investigating the ecological parameters include chemical oxygen demand (COD), biological oxygen demand (BOD), total dissolved solids (TDS), total suspended solids (TSS), dissolved oxygen (DO) and alkalinity. The results show that the use of the low impact reactive dyes has greater ecological advantages as it reduces the COD, BOD, TDS, TSS, pH values and increases the DO values of effluents. Organic cotton itself being eco-friendly along with Remazol series sustainable dyes provides the better ecological results. Hence, the results indicated that wet processing of organic cotton knitted fabric with eco-friendly and low impact reactive dyes provide better ecological advantages.

Eco frendily dyeing and finishing on silk fabriceSAT Journals
Abstract Today in the world of eco-friendly textiles, it becomes very important to solve the water pollution problem. Most of the textiles effluent came from dyeing industries spoil the water source and carcinogenic dyes create skin diseases and environmental hazards. So the present study focuses on plasma treatment, dyeing and fragrance finishing using natural sources. Plasma treatment is increase the dye uptake and luster in the silk fabric without more water consumption. Plasma treatment stands for, energy efficient, water saving, and economic than classical textile finishing processes. Traditional textile wet process needs lots of water to reduce the water consumption plasma treatment is used for surface modification of silk fabric. Plasma is a dry process is done by gases. Onion skin is a good dye yielding and antimicrobial source. These kind of natural sources are best alternative for synthetic dyes because these dyes are nature friendly dyes. Fragrance finish is a process where the substrate is subjected to inclusion of fragrance or essential oil which gives effects such as sedation, hypogynies, curing hyper tension. A new branch of textiles called “Aromatherapy textiles”, involves the incorporation of these essential oils on the textiles substrate for daily use.

Operational parameters affecting the removal and recycling of direct blue ind...IJEAB
In this work the ability of “bleached” oil mill solid waste to reduce the dyestuff content in industrial textile wastewater was studied. Bleaching treatment consists in a preliminary oil mill solid waste management with NaOH and NaClO2 for obtaining cellulosic materials, mainly removing lignin from the waste surface. Thus, a novel bioadsorbent from agricultural residues, named bleached olive pomace (OP), was presented. Direct Blue 78 was studied as a model azoic dye. Experiments were planned to study the effect of different initial conditions on the adsorption processes: oil mill waste amount as grains and as a fine powder (OPP), solution temperature values, initial dye concentration, pH values and electrolytes influence. The results showed that the adsorption process using bleached oil mill waste determined an excellent degree of water color reduction, reaching the best work conditions when pH 2 and OPP were used. The presence of electrostatic interactions was also suggested. The adsorption appeared to be influenced by temperature values showing an endothermic character. Interestingly, to confirm the role of ionic interactions between dye and sorbent at pH 2, fashionable results were obtained. The adsorption process was verified also at pH 6 with 100% of dye removal in presence of both NaCl and Na2SO4 avoiding the aforementioned strong acid conditions. A very important aspect of this work is the recycle of both the dye and the adsorbent, with particular attention to the dye reuse for coloring cotton fabric.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
