【Abstract】 The technique specifications of alkali deweighting of the acid-modified multicomponent copolyesterification fiber were investigated in this paper. Under the conditions of NaOH 7.5g/L,85℃, 40min, bath radio 1:40 and promoter 1631 lg/L,the satisfactory effect of silk likeness can be obtained. After The alkali deweighting,the special structure of micro-hollows appeared on the surface of fibers, and the crystallinity of fiber decreased.更多还原
