초록
섬유수축률 시험기로 연신비와 연신온도를 달리한 PET 필라멘트사를 상온에서 융점까지 온도를 올리면서 열수축률을 측정하여, 연신비와 연신온도의 변화에 따른 PET 필라멘트사의 열수축의 변화를 실험결과를 기초로 하여 연구하였다. 연신비가 3.0 이상인 경우의 PET필라멘트사의 열수축은 온도에 따라 증가하여 최대 열수축은 융점부근에서 나타났고 또 열수축은 연신비가 커질수록 증가하였다. 그리고 열수축은 연신온도의 증가에 따라서도 증가하였으나 연신온도가 10
The thermal shrinkages of poly(ethylene terephthalate) filament yarns which were manufactured at various draw ratios and drawing temperatures were measured by using Fiber Shrinkage Tester from the room temperature to the melting points. The effects of draw ratios and drawing temperatures on the thermal shrinkage-temperature curves were studied on the basis of experimental results. In the case of draw ratio 3.0 and above it, the thermal shrinkage increases with increasing temperature and draw ratio, therefore the maximum thermal shrinkage was observed near the melting point. The thermal shrinkage also increases with drawing temperature but in the case of drawing temperature above 100
