    Chapter 2 - Cotton value addition - Extraneous contamination in cotton 

     
     
    Extraneous contaminants in raw cotton have become a real nightmare to spinners worldwide. Spinners have been demanding low levels of contamination in raw cotton for the last three decades but, on the contrary, contamination in raw cotton has constantly increased. ITMF surveys show a two-fold increase in total contaminants worldwide in the last 15 years, while the end-users of yarn and fabrics demand incredibly low levels of contamination. Thus, spinners are under pressure from both sides.

    Contaminants present in the yarn result in huge volumes of fabrics and clothing being sold as seconds. Ultimately, the claims from the end-users are passed on to the spinners. It is quite unfortunate that the spinner is the one who is blamed for the presence of contamination in yarn, fabric and garments. Spinners pay a sizeable percentage of the total sales of their cotton and blended yarns on contamination claims, while they struggle and survive on very thin margins. Hence, they are forced to take steps to minimize the problem, even though the origin of the problem is elsewhere.

    Spinners are compelled to make huge investments in electronic gadgets fitted in the spinning process, especially in blow room and winding, to minimize claims. New developments are taking place to enable further detection in carding, draw frames, etc. But none of these gadgets can ensure 100% removal of all types of contaminants. The problem of contamination has to be dealt with at the origin. For this, accurate information is needed on the nature and amount of contamination in different origins of cotton and their impact on yarn and fabric quality.
