  • HEAT-BONDABLE FIBER AND NONWOVEN FABRIC
    Publication number: 20220162775
    Abstract: A heat-bondable fiber includes a core portion that includes a polymeric material selected from the group consisting of a polyester, a polyolefin, a polyamide, and combinations thereof; and a sheath portion made from a copolyester and surrounding the core portion. The copolyester has a melt flow index of not smaller than 11.5 g/10 min determined according to ASTM D2128-2010 at 120° C. A nonwoven fabric includes at least one matrix fiber and at least one the Heat-bondable fiber that are thermally bonded together. The matrix fiber is made from a polymeric material selected from the group consisting of a polyolefin, a polyester, cotton, and combinations thereof.

  • Copolyester resin for preparing a low-melting copolyester fiber, the low-melting copolyester fiber prepared therefrom, and process for preparing the low-melting copolyester fiber
    Patent number: 10836870
    Abstract: A copolyester resin for preparing a low-melting copolyester fiber is made by compounding a first copolyester with a second copolyester in a weight ratio of the first copolyester to the second copolyester of from 94:6 to 98:2. The first copolyester is obtained by subjecting terephthalic acid, ethylene glycol, isophthalic acid, and diethylene glycol to a copolymerization, and the second copolyester is obtained by subjecting terephthalic acid, ethylene glycol, and neopentyl glycol to another copolymerization.
