Abstract

Radiation grafting of acrylic acid to Polyester fabric has been studied by an impregnation method to render its surface more hydrophilic. Impregnated fabric was irradiated under nitrogen with gamma-ray from Co-60. The homopolymer formed usually could be extracted with water at 10$0^{\circ}C$. Graft-fabric exhibited a good acceptability to acid, basic or disperse dyes in conventional aqueous dye bath at moderate temperature.

Polyester 직포 표면을 친수화하기 위하여 함침법에 의하여 acrylic acid를 방사선 graft 공중합시켰다. 이때 함침된 직포를 질소에서 Co-60감마선으로 조사하였다. 생성된 Homopolymer는 10$0^{\circ}C$의 물에 의하여 대체로 유출되었다. Graft된 직포는 산성, 염기성 또는 분산염료에 대하여 재래식 저온 침염법에 의해서 염색이 잘 되었다.
