POLYESTER COMPOSITE FIBER WITH EXCELLENT TEXTURE AND COLOR

摘要

The present invention relates to a polyester composite fiber with excellent texture and color manufactured through composite spinning of copolymerized polyester prepared by copolymerizing: normal polyester as a core component; an acid component consisting of terephthalic acid or ester derivatives as a sheath component; and a diol component consisting of 2-methyl-1,3-propandiol, diethylene glycol and ethylene glycol. The 2-methyl-1,3-propandiol is input by more than 10 mol% and less than or equal to 50 mol% based on mole of ester in the copolymerized polyester, and the diethylene glycol is input by 1 to 25 mol%.;COPYRIGHT KIPO 2017
