Radiation-Induced Graft Copolymerization of Hydrophilic Monomer onto Nylon 6

Nylon직포의 표면을 친수화 하기 위하여 동시조사법으로 Acrylic acid를 방사선 graft중합시켰다. Monomer용액속서 침지된 Nylon직포를 공기중 또는 진공하에서 ${\gamma}$-선으로 조사시켰다. 직포 표면에 형성된 Polyacrylic acid는 10$0^{\circ}C$의 sodium hydroxide용액(0.1%)으로 대부분 추출되었다. 접목 반응된 생성물의 화학적 조성을 측정하였다. 접목반응된 Polymer와 방사선 처리를 하지 않은 polyamide를 비교하여 볼 때 흡수성이라든가 대전성은 증진되었다.

Radiation grafting of acrylic acid onto nylon fabric has been studied by "simultaneous irradiation" method to render its surface more hydrophilic. Nylon fabric immersed in monomer solution was irradiated in air or under vacuum with gamma-rays from Co-60. Most parts of polyacrylic acid formed on the surface of the fabric were extracted off from the fabric with 0.1% solution of sodium hydroxide at 10$0^{\circ}C$. The chemical components of the grafted product have been determined. By comparing graft polymer with ungrafted polyamide, the rate of water absorption and antistatic behavior are improved. improved.
