  • What is the acceptable contamination level for the end-user of yarn and cloth?

    Chapter 2 - Cotton value addition - Extraneous contamination in cotton

     
     
    There are no established standards for the size and frequency of contamination acceptable in knitted and woven fabrics worldwide. Contamination, even if it is a tiny single fibre, leads to downgrading of yarn, fabric and garments to second quality, or even total rejection of an entire batch or shipment.

    Most end-users demand zero contamination in the yarn and fabric without knowing the reality. A few, who understand, accept certain low levels, but even these levels are not within easy reach of spinners.

    The size of contamination objectionable to the end users could be as small as 1 mm or less, while electronic clearers equipped on winding machines cannot clear items less than 1 cm.
