Abstract: A method for the treatment of spider silk filament for use as a thread or composition in the manufacture of cosmetic, medical, textile, and industrial applications, wherein the spider silk filament, derived from genetically modified organisms, is treated with at least one component selected from the group consisting of vitamins, hormones, antioxidants, chelating agents, antibiotics, preserving agents, fragrances, dyes, pigments, magnetic nanoparticles, nanocrystals, cell adhesion enhancers, thermal insulators, shrinkage agents and cosmetic, medical or dermatological active substances. Textile fabrics obtained by this method are stronger, bio-compatible, bio-degradable and have a higher thermal conductivity. Treated spider silk filament can also be applied in an oil-in-water or water-in-oil protective cream that is hypoallergenic and ensures a firmer skin.

Abstract: An abrasion and fine resistant permanent press fabric or fabric structure comprising a batting or yarn consisting of an intimate blend of oxidized polyacrylonitrile and at least two fibers selected from the group consisting of polyvinyl halide, polybenzimidazole, p-aramid, m-aramid, fire resistant polyester and fire resistant rayon, said oxidized polyacrylonitrile comprising about 25 to 85% by weight of said yarn and p-aramid comprises less than 35% by weight of said yarn or batting.
