• Effect of the initial level of fibrous contamination in bales on residual level in yarn

    Chapter 2 - Cotton value addition - Extraneous contamination in cotton 

    As mentioned earlier, fine hair, fine polypropylene and fibres from coloured yarn or cloth pieces are the most difficult of the fibrous contaminants to deal with. These contaminants are beyond the control of the spinning process, as they have the same buoyancy as cotton and can be twisted easily along with cotton fibres. Hence, it is very important to have low level of fibrous contaminants in the cotton.

    Experience suggests that a level of less than 1 gram of fibrous contaminants per ton of raw cotton bales would help spinners to satisfy their customers and avoid complaints and claims, with due support from electronic gadgets in the blow room and winding processes.
