Abstract
When a fiber is treated with a organic solvent the orentation decreases and the crystallinity increases. In this study, it was attempted to investigate on the change of the fine structure of nylon 6 filaments which were treated in aqueous solutions of formic acid. And in order to search for the method to prevent the deterioration in physical properties by the restraint of decrease of orientation, the filaments were treated under the unrestrained and the constant length conditions and some of the filaments treated under the unrestrained condition were redrawn to the original length. And they were investigated in contrast with one another. The orientation of fiber decreased and the crystallinity of fiber increased very much even at 30
일반적으로 섬유를 유기용제로 처리하면 그 배향도는 감소하고 결정화도는 증가하게 된다. 본 연구에서는 formic acid 수용액 중에서 처리된 nylon6 filament의 구조변화를 중심으로 고찰하였다. 또한 용제처리에 의한 물성저하의 원인이 되는 배향도의 감소를 방지하기 위한 방법을 찾아보기 위해 시료를 정장처리, 그리고 무긴장처리 후 수축분에 대해 원래 길이대로 재연신 해서 서로 비교검토해 보았다. 먼저 nylon섬유에 대한 용해능이 큰 formic acid 수용액 처리시에는 3
