링 정방공정중의 사절수 추정

Estimation of End-Breakages in Ring Spinning

링정방 공정중의 사절수를 추정하기 위하여 간단한 수학적 모델를 만들었다. 사절현상에 가장 중요한 방사장력, 및 단사강력 만을 고려하여 사절수에 가장 기여도가 큰 요인을 찾아내고 사절율을 이론에 의해 유도하였다.

A Study on the end breakages in ring spinning by simple mathematical model has been carried out. The most important factors such as yarn strength, yarn strength variation, spinning tension and spinning tension variation were considered among the factors known as affecting the breakage phenomena. The relative importance of such factors was investigated and the number of end breakages based on the mathematical model was calculated. From the theoretical results, it could be concluded that the value of end breakage rate is obtained and the most important factor contributed to breakages is yarn irregularity.
