ITMF COTTON CONTAMINATION SURVEY 2003
Foreign matter, stickiness and seed-coat fragments in raw cotton continue to be among the most serious problems affecting the cotton spinning industry world-wide. This is the conclusion to be drawn from the "Cotton Contamination Survey 2003 which has just been released by the International Textile Manufacturers Federation (ITMF). The survey is carried out every other year, the 2003 edition being the eighth in the series since the changeover to a new methodology in 1989. In the 2003 report, 75 growths were evaluated by 220 spinning mills located in 23 countries.
Contamination - affecting more than one-quarter of cotton growths
With 26% of all cottons evaluated found to be seriously or moderately contaminated, the overall level of contamination has risen for the third consecutive survey. The cottons evaluated in 2003 were in 8% (2001: 6%) of all cases found to be seriously contaminated by 16 different sources of foreign matter, a further 18% (2001: 16%) were moderately contaminated, leaving only 74% (2001: 78%) insignificantly or not at all contaminated. As these summary data are arithmetic averages, the extent of contamination is fully illustrated only by the results for the individual contaminants, which range from 6% for "tar" (unchanged from 2001) to a full 50% of all cottons processed being either moderately or seriously contaminated by "organic matter", i.e. leaves, feathers, paper, leather, etc. (up from 39% in 2001). Other serious contaminants are strings made of jute/hessian, cotton, and woven plastic, "inorganic matter" in the form of sand or dust, and cotton or jute/hessian fabrics. Also of concern are, in descending order of incidence, woven plastic fabrics, strings and fabrics made of plastic film, and grease or oil. The most contaminated descriptions continue to originate in India, Turkey and Central Asia (Uzbekistani & Tajikistani medium staple growths). In contrast, clean cottons can be sourced from the USA, Zimbabwe, and selected West African origins (Senegal and Chad).
THRAKIKA EKKOKISTIRIA S.A.
Thrakika Ekkokistiria S.A. considering and recognizing that contamination is one of the most serious problems in textile is trying to prevent it with two ways.
1. USE OF JOSSI VISION SIELD
Thrakika Ekkokistiria S.A. introduced two years ago in the production chain the Vision Shield 96'' Single of the JOSSI company. Any foreign material is being detected from that machine and is eventually dropped out. THRAKIKA EKKOKISTIRIA S.A. is the first ginnery in the world that possesses this type of equipment.
2. BALES WITH COTTON COVER
In addition we are using a cotton-made cover for our bales instead of plastic bags, preventing this way contamination in the spinning mills.
