EVA로 Blending된 Polypropylene Fiber의 염색성에 관한 연구

A Study on the Dyeing Property of EVA Blended Polypropylene Fiber

Polypropylene-ethylene/vinyl acetate copolymer (PP-EVA) blends were prepared by mechanical blending using relatively semi-crystaline ethylene-vinyl acetate copolymer and polypropylene. In order to obtain dyeable PP fiber, PP-EVA blends were prepared using below 10wt.％ of EVA and formed a filament by the melt spinning method. The resultant fibers had tensile strengh of 2∼3g/d, elongation of 330∼600%, initial modulus of 22∼46g/d, and exhibited markedly improved dyeing property.
