Problem one, get together fat cotton is unusual fiber is phyletic

Answer: Get together fat cotton at campaign because before spin or be hind filature condition problem, hard to avoid causes a few unusual fiber, use especially reclaim the second birth cotton that section produces, produce unusual fiber more easily; Unusual fiber large base can be divided into following number sort;
(One) odd root is thick: Outspread not complete fiber, this kind of fiber causes colored easily unusual, affect without what spin cloth to beardless colored less, but to be being used at leatheroid base the water card clothing of cloth or needle-punched non-wovens have serious effect.

(2) and silk: Outspread hind root or two 3 fiber above are stuck together, this kind of fiber causes colored easily unusual, affect without what spin cloth to beardless colored less, but to be being used at leatheroid base the water card clothing of cloth or needle-punched non-wovens have serious effect.

(3) glue shape: Outspread during produce fracture of wire or pester silk, make fiber is done not have completely outspread form hard cotton, this kind of product can be divided into shape of gum of shape of shape of one form gum, 2 form gum, 3 form to wait again. Course of this kind of unusual fiber combs after cotton project, often deposit is above card clothing create web take shape not the problem such as beautiful or broken net, this kind of raw material does not have the finished product that spin cloth to be able to cause serious character defect to much.

(2) if will get together,fat section changes qualitative change sex to make rise have flame retardant effect. Lasting effect flame retardant fiber great majority uses denaturation get together flame retardant of fat section production gets together fat cotton, change qualitative agent basically to be phosphorous series compound, use phosphor the oxygen in Yugaorehui and air is united in wedlock, the character that reduces aerobic content is achieved good flame retardant the effect.
