Abstract
In the treatment of fiber with thermoplastic resin in liquid medium, the solvent is usually organic. If water solvent is needed, resin-water emulsion must be used, but this emulsion treatment is unsuitable for intra-treatment of fiber. We succeeded in intra-treatment of silk fiber with vinyl resin in aqueous medium using calcium acrylate monomer. Light resistance, strength and elongation of silk fiber by this treatment are reported in this paper.
Generally the tensile and flex strength of the fiber are superior to those of the thermosetting resin-treated. The light resistance is also higher than thio-urea treated fibers. The improvement of yellowing of the fiber treated with a somewhat concentrated solution of the acrylate resin is discussed.
