초록

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.

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.
