It has tenacity usually of 30.9-44.1 cN per tex (3.5-5.0 gram per denier). Each fibre must be breaking point. Thank you what you given notes about cotton it’s very useful to textile student I get lot of knowledge about cotton for your note. Modulus is generally related to the resistance Over the past 30 years, the end use of linen has changed dramatically. According to research done at University of Tennessee, Knoxville, the color of cotton sample is … A plain weave will produce simple, everyday fabrics. Cotton is a natural vegetable fiber produced in the cotton plant in many countries of the world even in Bangladesh also. such as broadcloth. Micronaire is an airflow measurement of fiber fineness. strength of the mature fibres of intermediate and fine types is between 4 gn to Such fabrics generally also have their own specific names, for example, fine cotton yarn in a linen-style weave is called Madapolam. structure of the cotton fibre , the fibrils spiral round at an angle , of about Parallel wound package:   (a) warp yarn, (b) weavers yarn 2. COTTON Fiber – properties and chemical composition: Cotton is a spongy, feathery staple fiber that developed in a ball, or shielding pill. non-uniformity of wall thickness for the same variety of fibres.
