Abstract

The effects of surface treatment carried out to improve the spinnability and anti-static property of angora rabbit fibers were studied. Angora rabbit fibers were treated with a mixture of 0.5%(wt%) formic acid and 1.5%(wt%) hydrogen peroxide (1:1 v/v) for 60, 80 or 100 minutes at 40, 60 or 80 $^{\circ}C$. The effects of treatment time and temperature on the surface structure, tenacity, elongation, tensile modulus and surface resistance were investigated. Scales of the cuticle layer were effectively raised without lowering the tenacity when treated for 80 minutes that of the untreated. The tenacity and the tensile modulus decreased slightly with the increase of treatment time and temperature, while the elongation and the surface resistance increased markedly. It should be noted that the influence of treatment temperature on the decrease in surface resistance of the treated fibers is more significant than that of treatment time.
