Performance of Collagen Modified PAN Fiber

摘要

PAN fiber is one that contains at least 85% by mass of acrylonitrile co-monomer in the polymer chain. It has low moisture-absorbency and electrostatic tendency. Using collagen modified PAN fiber can overcome the shortcomings. Collagen modified PAN fiber is a kind of surface modification fiber which was hydrolyzed by NaOH aqueous solution first, and then grafted with collagen. The performance of collagen modified PAN fiber was studied. The results show that: compared with PAN fiber, the surface of collagen modified PAN fiber is smooth and covered by collagen composition, the moisture regain increased from 2% to 6.1%, the breaking strength and elongation of collagen modified PAN fiber are decreased, the breaking strength is 2.31 cN/dtex, the breaking elongation is 22.8%, dyeing properties of collagen modified PAN fiber with cationic dyes and acid dyes are excellent and the goods have bright color and good color fastness.
