ABSTRACT
Raw material represents major share in the manufacturing cost of a short staple spun yarn. This fact alone is sufficient to indicate the significance of the raw material for the yarn producer. The condition becomes more critical while dealing with natural fiber like cotton with inherent variations in its characteristics. These variations are affected by region and time of cultivation, crop cultivation conditions, monsoon schedule and ginning practices. These lot to lot variations influence becomes still more apparent when the ease
in processing fiber material of first lot is compared with the difficulties, annoyance, additional effort, and the decline in productivity and quality associated with subsequent lots of similar material. Through blending of large volume of cotton become necessary for any spinner to use a problem-free raw material and retain consistency in producing yarn quality for a long period of time. But it would normally be too expensive and demands huge initial investments with added burden of inventories and maintenance.
