HIGH WATER-ABSORBING/QUICK-DRYING POLYESTER YARN HAVING X TYPE CROSS SECTION

摘要

PROBLEM TO BE SOLVED: To obtain a polyester yarn having an X type cross section with water absorbing properties and quick-drying properties than those of a conventional yarn in use not only for silk but also for finished yarn, useful as a material for sport clothing or inner clothing by making the yarn have a specific intersection angle and a specified porosity. SOLUTION: This polyester yarn having an X type cross section has a single yarn cross-sectional shape of X type section with four leaf projection parts around the yarn in which one intersection angleθis 95-130 degrees and the porosity of the yarn is 10-35%. The polyester yarn having an X type cross section has 10-80 modified cross section degree of four recessed parts of the single yarn cross section. The modified cross section degree of four leaf projection parts is preferably 0.7-1.5. Preferably a multifilament yarn having 10-250 mm average opening length is constituted from the high water-absorbing/quick- drying polyester yarn having an X type cross section.
