Several types of wastage are found during the processing of row cotton in spinning mill 12-13% wastage are produced for card process and 25-30% wastage are produced for combed process. The names of different wastage are given below, 1. Blow-room of waste = [3%] i. Droppings-2 ii. Lap waste. 2. Carding of waste = [3-5%] …

The purpose of adding ‘fabric softeners’ at the end of the washing process is to neutralise the very small amounts of detergents left in the textiles and thus prevent static electricity. During the rinsing cycle of laundering, the detergents are diluted between 1000 and 10000 times, so the concentration of detergents in the water of …

Regenerated Fiber The fiber which is converted from natural polymer into synthetic polymer is called regenerated fiber. In other words, the fiber which is obtained by conversion of natural fiber by chemical process is called Regenerated Fibers. Sequence of ‘Man Made’ …

However, the process of interlacing warp yarn with the inserted weft yarn in a definite order to form a fabric suitable for use as a dress material or industrial purpose is called weaving. The machine used for this purpose is called Loom. In a woven fabric, the …

Continue reading Denim Processing with EnzymesThe majority of cotton denim production today is “surface polished” with enzymes to yield improved softness, reduced pilling propensity and brighter colors. Both nontoxic and environmentally friendly, enzymatic treatment has recently been expanded to cellulosic woven and knitted goods and to cellulosic blends as more specific enzyme preparations became available at affordable costs. Very small …
Continue reading Effect of Enzymatic Treatment on Dyeing and Finishing of Cellulosic FibersIt has been predicted that future development and progress of textile industry in India would be driven by the demands from garment manufacturing industry which in turn would be influenced by export markets. Under these circumstances processing of garments also assumes an unprecedented importance. Qualitatively speaking, finishing enzymes find major application in textile processing, next …
