INTRODUCTION Today’s slogan in the international textile or any other market is quality, so the production or yield % stand at second priority, no doubt high production is an even demand of world population. Contamination free textiles are the ultimate target of the manufacturer along with other quality control applications. Page 3
Cotton sorter is used for foreign material detection in the blow room. The contaminants are removed by means of very fast pneumatic ejectors. Cotton sorter is useful to improve the quality of raw material and also upgrade the low quality cotton bales by removing contamination. Page 4
Definition of contaminants
Page 5
Contaminants in cotton can be described as a deviation in color and size The line camera interprets a defect as color level deviations The contaminant size is defined as a combination of contaminant width and contaminant length
Some contaminant Regions High level of contamination India, Pakistan, Sudan , Uzbekistan, Syria, Egypt Lower level of contamination Argentina, Israel, Mali, USA, China, Turkey, Sudan, Zimbabwe, Uganda, South Africa Page 6
The CottonSorter in the blow line
Detect foreign fibres and contaminants in raw cotton ▪ jute parts, packaging material, parts of cloths, burnt tufts, oil, dirt, plastic, feathers, etc. ▪ wood, leaves, branches, stones, etc.
Remove the contaminants by means of very fast pneumatic ejector
Page 7
Affect of contamination (present in cotton bale) on constructed fabric If a 3cm by 3cm contaminating rag is present in a cotton bale then
Output of the card is 20 meter contaminated sliver
Output of a two step drawing process (E=8x8) is 1280 meter contaminate sliver.
Output of a spinning spindle (E=150) is 192.000 meter contaminated yarn.
In this yarn there will be a contamination each 5 meter.
The fabric construction will result in 6 contaminations/cm .
