Abstract

Nylon fabrics were corona treated with different current intensity (5, 10, 15, 20 A) and feeding speed (5, 10, 15 m/min). We confirmed the change of nylon fabrics surface using X-ray diffraction apparatus, scanning electron microscopy (SEM) and X-ray photoelectron spectrometer (ESCALAB). And the change of physical properties through measuring the tensile strength, tear strength, bonding and wet bonding strength. Thermosetting reactive polyurethane hot melt adhesive was used in the adhesion of nylon fabrics. Functional groups were introduced on nylon fabric surface by treating the fabrics in air atmosphere with corona discharge, and the result adhesion was improved. Bonding strength of the nylon fabric treated with corona was increased with increasing current intensity and decreasing feeding speed.

나일론 직물들이 전류세기 5, 10, 15, 20 A, 공급속도 5, 10, 15 m/min로 코로나 처리되었다. 나일론 직물의 표면변화를 X-ray 회절장치, 주사전자현미경(SEM)과 X-ray 광전자분석기(ESCALAB)로 확인하였다. 또한 물리적 성질의 변화를 인장 인열강도, 접착 및 습윤강도를 통하여 측정하였다. 접착에 사용된 접착제는 열경화성 반응형 폴리우레탄 핫 멜트 접착제이다. 대기압에서 코로나 방전처리에 의해 나일론 직물에 관능기들이 도입되어졌고, 그 결과 접착력은 향상되었다. 코로나 처리된 나일론 직물의 접착강도는 전류 세기가 증가할수록, 공급속도가 감소할수록 증가하였다.
