POLYESTER SPECIAL FINISHING YARN MAKING METHOD

摘要

Two kinds of polyester multifilament yarn having a different degree of orientation are multi-twisted by belt twisting device to obtain polyester yarn exhibiting a superior drape property and a soft combed wool-like feeling owing to the fine double-shrinkage structure. Non- drawn yarn A, B are air-jet treated and twisted with drawing, and the two highly and lowly oriented non-drawn yarn A and B have birefringence ratio 40-80 X 30-3and 15-30 X 10-3, respectively.
