Studies on the improvement of fiber by polymer blend.

개질섬유에 관한 연구 (I)

In order to investigate the improvement of alginate fibers some blended yarns were prepared with sodium alginate (SA) and polyvinylalcohol (PVA), using an coagulation bath of 33% calcium chloride and sodium chloride. Blended yarns were treated with variuos acetalization bath (60 min. immersion in 10% formaldehyde, acetaldehyde, butylaldehyde and benzoaldehyde solution and in acetylation bath of acetic anhydride 3.1 mol/ι), zinc choloride (1.3 mol/ι) as a catalyzer. Some Properties such as dry or wet elongation and strength were measured and specially some results were obtained in this ivestigation.
