PREPARATION OF PRODUCING HIGH POROUS POLYMER FIBER BY USING CONJUGATED SPINNING

摘要

One reformed polyester as seath component to give irregularly leached surface and another reformed polyester as core component whose speed of loss in weight by alkali soln. is faster than that of seath component are conjugately spun so that the content of core component is 40-90% of the cross section area of yarn. In the weight reduction process, a hollowness of 40-90% is obtained by extracting core component.
