A yarn evenness level evaluation of the works, the main consideration of fiber length, fineness influence on a dry level, also consider fiber uniformity, maturity, water cut, impurity, the influence of such factors as linter content. Among them, the regulations in our country cotton moisture content is 10%, the highest limit is 12%; Impurity rate for serrated cotton 2. 5%, roller ginned cotton. 3. 0%. Two yarn strength level evaluation, taking into account the number of fibers in the yarn cross section, the influence of fiber length, single fibre strength. Three yarn material costs assigned to each scheme in all kinds of raw material mixing ratio weighted yarn material costs as the cost of the cotton assorting scheme evaluation index. Four yarn value this is a comprehensive evaluation index, it consider cost, and do strong. Five inventory for each cotton assorting scheme of various raw materials inventory clear answer: raw material enough or not enough. On the basis of the scheme can be used. Such as: OE10S ( Evenness, three in uz level around 25%, strength of 610 n) : 35% raw cotton ( Level 3 cotton) + 65% residues Fine, cut knife, yards, back to spend) OE16S( Evenness, three in uz level around 25%, strength of 380 n) : 50% raw cotton ( Level 3 cotton) + 50% residues Fine, cut knife, yards, back to spend) Ring spun C21 ( Evenness, three in uz level around 25%, strength of 436 n) : 100% raw cotton ( Level 3 cotton) Ring spun C21 ( Evenness, and three levels by about 75%, strength of 293 n) : 100% raw cotton ( Level 4 cotton)
