Rationale
Natural fibres—cotton, flax, silk, and wool—represent the major fibres available to us. Cotton accounts for almost 50% of the worldwide consumption of textile fibre. Worldwide cotton production is annually about 80 to 90 million bales (17.4 to 19.6 billion kg). China, the United States, India, Pakistan and Uzbekistan are the major cotton-producing countries, accounting for over 70% of world cotton production. The rest is produced by about 75 other countries. Yarn manufacturing is a sequence of processes that convert raw cotton fibres into yarn suitable for use in various endproducts- like- weaving, knitting, lace making, felting, and braiding or plaiting, etc. A number of processes are required to obtain the clean, strong, uniform yarns required in modern textile markets.The industries are competing with technological up gradation and automation to reduce cost, increase quality, increase production, and variety with product mix and colours. More & more knowledge and skills are expected by the industries in fresh pass outs. This course is one such effort to develop knowledge and skills in the area of Blow room process & carding process. Since India is one of the largest manufacturers of yarns, it is must for students to develop competency in this area for getting good employment.
