Types, Factors and Functions of Sequestering Agent in Dyeing

Sequestering Agent and Its Function in Dyeing: Sequestering agent is essential chemical which is used during dyeing for removing hardness of water that prevent metal ions in water from interfering with dyeing processes, ensuring consistent color quality and process efficiency. Sequestering agents combine with calcium and magnesium ions and other heavy metal ions in hard […]

Cost Calculation in Singeing Process

Calculation, Wet Processing

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

Role of Enzymes in the Textile Industry

Wet Processing

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

Kier Boiling Process in Textile

Wet Processing

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

Enzymes in Textiles: Classification, Advantages and Application

Wet Processing

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

Screen Printing Versus Digital Printing

Printing, Wet Processing

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

Pretreatment Process in Textile Materials

Wet Processing

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,
