Jute is a natural fiber obtained from the stems of the jute plant. It is the second most produced textile fiber in the world after cotton. India, China, and Bangladesh are leading producers. The fiber goes through cultivation, harvesting, retting, stripping, washing, drying, baling, and packing processes. Jute has good antistatic properties but low crease resistance and drape. It is biodegradable and used widely in sacks, carpets, rugs, and other products due to its low cost. However, it has poor strength when wet and loses strength with sunlight.
Jute fiber has potential for use in technical textiles but requires improvements to its properties. A series of wet chemical processes can modify jute fiber, making it softer, finer, and brighter with improved moisture regain and bundle strength. Specifically, sulphonation increases properties by treating fiber with sodium sulphate. Enzyme and aminosilicone treatments increase swelling and flexibility while decreasing rigidity. Thermal treatments like boiling water for 30 minutes also reduce fiber rigidity. With further research into such modification methods, jute fiber performance could be enhanced for technical textile applications.

Experimental study was conducted to investigate the use of coir fiber as reinforcement in cement composites. Coir fiber was treated with natural latex before being added to concrete in lengths of 20mm, 25mm, and 30mm at percentages of 0.5%, 0.75%, and 1%. Compressive strength tests at 7, 14, and 28 days showed that strength initially increased up to 0.75% fiber content and then decreased. The maximum compressive strength was achieved using 25mm fiber at 0.75% addition. The study concluded that coir fiber improves concrete properties and resistance to sulphate attack while reducing environmental pollution compared to synthetic fibers.

Milling technique for production of micro particleskhadija khawar
This document summarizes two milling techniques: fluid energy milling and ball milling. Fluid energy milling uses high velocity air streams to accelerate drug particles and collide with each other, reducing particle size down to 3-5 micrometers. Ball milling uses attrition forces within a rotating vessel containing balls and rods to crush drug particles through collision down to sizes below 10 micrometers. Both techniques are effective for micronizing drugs to improve dissolution, solubility, and bioavailability.

Tensile strength of fiber for some type bananas (ambon, kepok, susu)eSAT Journals
Abstract The purpose of this study was to determine the influence of alcohol soaking treatment on the fiber surface in the physical and mechanical properties of banana fibers and to determine the effect of fiber tensile load when mixed with an epoxy resin with a volume fraction in the form of pull. The results obtained from this study was the influence of alcohol soaking treatment on the surface of banana fiber on the physical properties and mechanical properties of banana fiber are not suitable, because it just makes banana fiber strength becomes strong or fragile. The influence of tensile load of fiber when mixed with an epoxy resin with a volume fraction of 50: 50 in the form of pull sufficient effect on the tensile strength of the composite, as it makes the tensile strength of the composite itself to be increased or stronger.

This document summarizes research on producing porous and non-porous cellulose membranes from a novel solvent system. Cellulose and cellulose-polysaccharide blends were dissolved and cast into membranes. Both microporous membranes with 200nm pores for cellulose alone and 1000nm pores for blended membranes, as well as non-porous membranes, were produced. Analysis showed the cellulose membrane had a cellulose II crystal structure while the blended membrane was amorphous. The blended membrane also showed improved water absorbency and mechanical properties over pure cellulose membranes.
Effect of Recycling of Nanocellulose on their barrier properties and mechanic...Kirubanandan Shanmugam
The document summarizes research on the effect of recycling on the barrier and mechanical properties of nanocellulose films. Nanocellulose films were made via spray coating and then recycled using dispersion and vacuum filtration. Testing found that recycled films retained 70% of the strength of virgin films and had double the water vapor permeability. Examinations across multiple length scales suggested this was due to nanofiber bundles that were not fully separated during recycling, reducing density and uniformity and thereby properties. While recycling reduced performance, barrier properties remained better than conventional cellulose packaging. Further optimization of the recycling process may be needed to fully separate nanofibers.

Treatment of Domestic Wastewater Using Chemical Coagulation Followed by Geote...paperpublications3
Abstract: The emphasis of this paper is on the filtration performance of geotextiles. As we know treatment of wastewater has become an absolute necessity. An innovative cheap and effective method of purifying and cleaning wastewater before discharging into any other water systems is needed. Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration to enhance the ability of a treatment process to remove particles. Filtration is considered the most important solid-liquid separation process in water treatment, as well as in wastewater treatment. Geotextile are indeed textiles in the traditional sense, but they consist of synthetic fibers rather than natural ones such as cotton, wool, or silk. Thus bio degradation and subsequent short lifetime is not a problem. These synthetic fibers are made into flexible, porous fabrics by standard weaving machinery or are matted together in a random non-woven manner. Proper selection of geotextile filters plays a key role in achieving satisfactory filtration performance.

Jute is collected from the stem bark of Corchorus capsularis and Corchorus olitorius plants. The stems are cut before flowering and undergo a retting process where they are soaked in water. This softens the fibers and allows them to be separated from the inner woody core. Jute fibers are long, golden yellow in color, and contain high amounts of cellulose. They are used to make cloth, sacks, twine and rope. Hibiscus cannabinus fibers can substitute for jute.
This document provides information about banana fibers. It discusses how banana fibers can be extracted from the pseudostem of banana plants through mechanical or retting methods. The physical and chemical properties of banana fibers are then outlined, noting their high cellulose content which provides strength. Banana fibers are comparable to sisal in terms of properties. Applications of banana fibers include use in textiles, furniture, and other products due to their desirable characteristics.
Jute is a plant fiber that grows well in India and Bangladesh. It is composed mainly of cellulose and is used to make bags, sacks, carpet backing, twine, and other products. The jute cultivation process involves land preparation, sowing seeds, irrigation, harvesting the plant, and a retting process to separate the fibers from the stem. Some defects that can occur in jute fibers include being rooty, specky, croppy, or weak due to issues with retting, harvesting, or storage. Jute fibers are composed mostly of cellulose and lignin and are resistant to acids, alkalis, insects and mildews.
This document provides an overview of the objectives and syllabus for a Textile Science course offered at the National Institute of Fashion Technology in Gandhinagar.

This document discusses kapok fibre, including its structure, properties, and applications. Kapok fibre is a natural cellulosic fibre extracted from the kapok tree. It has a hollow tubular structure that makes it buoyant, compressible, and an excellent sound and heat insulator. Due to its hydrophobic waxy surface and hollow structure, kapok fibre can absorb large amounts of oil but not water. Some applications of kapok fibre include use in upholstery, bedding, insulation, and as a material for life jackets and lifebuoys due to its oil absorbency and buoyancy.
The use of enzymes in the textile chemical processing is rapidly gaining globally recognition because
of their non-toxic and eco-friendly characteristics with the increasingly important requirements for textile
manufactures to reduce pollution in textile production. Furthermore, the use of enzymes results in reduced
process times, energy and water savings, improved product quality and potential process integration. Variation
of knit fabric and enzyme concentration is taken to do this project. The aim is to know the effect of enzyme
concentration on the physical properties of knit garments of various constructions. In this project 0.4 g/l and 0.5
g/l enzyme concentration is taken to wash Single Jersey and Rib fabric. Then to see the effect of enzyme
concentration on the physical properties of Single Jersey and Rib fabric some tests like GSM, Bursting strength,
Dimensional Stability and Pilling are done. The results of before and after enzyme wash is compared to know
the effect of concentration of enzyme on the physical properties of Single Jersey and Rib fabric. After enzyme
wash GSM of the fabric increases, Dimensional Stability and Bursting strength decreases and pilling formation
on the fabric surface also decreases.

Sutures can be classified into absorbable and non-absorbable types based on how the body breaks them down. Absorbable sutures such as polyglycolic acid and polyglactin 910 degrade over time as the wound heals, while non-absorbable sutures like polypropylene, nylon, polyester and stainless steel resist breakdown and typically need to be removed. Sutures can also be monofilament or multifilament, and coated or uncoated, with these properties affecting factors like tensile strength, tissue reaction and knot security. Common sutures discussed include catgut, polypropylene, nylon, polyester, silk and steel.

Suzanne Lagerweij - Influence Without Power - Why Empathy is Your Best Friend...Suzanne Lagerweij
This is a workshop about communication and collaboration. We will experience how we can analyze the reasons for resistance to change (exercise 1) and practice how to improve our conversation style and be more in control and effective in the way we communicate (exercise 2).
This session will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
Abstract:
Let’s talk about powerful conversations! We all know how to lead a constructive conversation, right? Then why is it so difficult to have those conversations with people at work, especially those in powerful positions that show resistance to change?
Learning to control and direct conversations takes understanding and practice.
We can combine our innate empathy with our analytical skills to gain a deeper understanding of complex situations at work. Join this session to learn how to prepare for difficult conversations and how to improve our agile conversations in order to be more influential without power. We will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
In the session you will experience how preparing and reflecting on your conversation can help you be more influential at work. You will learn how to communicate more effectively with the people needed to achieve positive change. You will leave with a self-revised version of a difficult conversation and a practical model to use when you get back to work.
Come learn more on how to become a real influencer!

Carrer goals.pptx and their importance in real lifeartemacademy2
Career goals serve as a roadmap for individuals, guiding them toward achieving long-term professional aspirations and personal fulfillment. Establishing clear career goals enables professionals to focus their efforts on developing specific skills, gaining relevant experience, and making strategic decisions that align with their desired career trajectory. By setting both short-term and long-term objectives, individuals can systematically track their progress, make necessary adjustments, and stay motivated. Short-term goals often include acquiring new qualifications, mastering particular competencies, or securing a specific role, while long-term goals might encompass reaching executive positions, becoming industry experts, or launching entrepreneurial ventures.
Moreover, having well-defined career goals fosters a sense of purpose and direction, enhancing job satisfaction and overall productivity. It encourages continuous learning and adaptation, as professionals remain attuned to industry trends and evolving job market demands. Career goals also facilitate better time management and resource allocation, as individuals prioritize tasks and opportunities that advance their professional growth. In addition, articulating career goals can aid in networking and mentorship, as it allows individuals to communicate their aspirations clearly to potential mentors, colleagues, and employers, thereby opening doors to valuable guidance and support. Ultimately, career goals are integral to personal and professional development, driving individuals toward sustained success and fulfillment in their chosen fields.
