Singeing Process in Textile: Singeing is the process of removing protruding fibers from the fabric by burning them out. When yarn is made from short staple fibers, the two ends of the fiber may not be embedded inside the yarn and are projected due to the twist imparted during spinning. For multifilament yarns, some filaments […]

Enzymes in the Textile Industry: Enzymes were discovered in the second half of the nineteenth century, and since then have been extensively used in several industrial processes. Enzymes are macromolecular biocatalysts that mediate virtually all of the biochemical reactions that constitute metabolism in living systems. Enzymes are generally globular proteins and like other proteins consist
What is Kier Boiling? Kier boiling is often referred as scouring which is the hot alkaline process necessary to remove the non-cellulosic impurities. Kier boiling is an important step in the pretreatment of textiles, particularly for cotton fabrics. The main effects of this treatment are a 5–10% loss in mass and an improvement in wettability
What is Enzyme in Textile? Enzymes are proteins, the spatial arrangement of which is typical, and occurs through helical segments, folding leaf structures, intramolecular associations, and, particularly, by the targeted incorporation of protin as an amino acid, which disturbs arrangement. It helps to accelerate chemical reactions without being consumed in the process. Each enzyme has

What is Screen Printing? Screen printing is done either with flat or cylindrical screens made of silk threads, nylon, polyester or metal. The printing paste or dye is poured on the screen and forced through its unblocked areas onto the fabric. Based on the type of the screen used, it is known as ‘flat screen
What id 3D Printing? 3D printing is the process of creating three-dimensional objects through joining or solidifying material under computerized control. 3D printing (3DP), also known as additive manufacturing. In this process, a computer-aided design (CAD) is converted into a 3D object by printing the material layer by layer and joining them in the form

What is Pretreatment Process in Textile? In textiles, pre-treatment is a processes applied on textile material (viz. fibres, yarn, woven and knit fabrics) to prepare the material for dyeing, printing or finishing. Pretreatment plays a crucial role in achieving consistent and high-quality results in textile processing. As the grey material will have lot of impurities,
What is Value Addition Processes? Value addition on fabrics is the process of enhancing the quality, aesthetics, functionality, and overall value of textile materials. It involves applying various techniques, treatments, or processes to fabrics to improve their appearance, performance, or utility. The fabric coming from the loom does not have properties such as absorbency, softness

Definition of Textile Wet Processing: Textile wet processing is a series of chemical and mechanical treatments that are used to alter the appearance, performance, and durability of textile materials after they have been woven or knitted, but before they are made into finished products. These techniques are performed using water or other liquids, which is
