| Abstract: | Long polyester fibres with 10-60% shrinkage were prepared from high speed winded spinning POY by using different drafting speeds and temperatures. Variations in crystallinity and degree of orientation of the specimens were determined before and after the shrinkage. The effect of shrinking temperature and time on the shrinkage as well as the relationship between the shrinkage and the fibre strength are discussed. |
