Abstract
Nylon 6 wet spinning fibers prepared by using phenol (Ph) or formic acid (FA) as solvent were heat-treated for 10-120min. or drawn 2-4times in air at 150°C or in water at 65°C. And the effect of heat-treatment or drawing on size and content of voids is studied in relation to dye and water absorption behaviors.
Data obtained are summerized in the following table. _??_; increase, _??_; decrease, h. t.; heat-treating, d.; drawing
