The method for preparation of self-extending polyester composite yarn with trilobal cross sectional POY

摘要

the present invention is a mono-denier (mono denier) in thickness is 0.5 ~ 2 de, and the total denier of 50 by applying this method using a spontaneous elongation of ~ 120 de polyester POY of samyeop section, 9 give the O / F (over feed) and 25% of the thickness of the mono-denier and a 1 ~ 10 de, a total denier 30 ~ 120 de of the modified cross-section polyester SDY Processing Corporation is a total denier between 100 and 250 denier by air entangling spontaneous renal relates to a finished yarn and a method of manufacturing the same. ; spontaneous elongation of the present invention, modified cross-section it is possible to obtain a unique touch and elegant luster due to the process of buying POY samyeop cross-section, it can be O / F control of the voluminous and punished in accordance with the POY kigam, and yet has the functionality of such quick-drying.
