Abstract
A thermoplastic copolyester elastomer-based yarn and a method of making a thermoplastic copolyester elastomer-based yarn are disclosed. The yarn comprises a filament that is formed from a thermoplastic copolyester elastomer composition comprising a thermoplastic copolyester elastomer containing hard segments and soft segments. The thermoplastic copolyester elastomer exhibits a flexural modulus of about 300 MPa or less as determined in accordance with ISO 178:2019 at a temperature of about 23° C. and a melting temperature of from about 100° C. to about 230° C. as determined in accordance with ISO 11357-3:2018. The yarn has a linear density of from about 1 to about 2000 denier per filament and exhibits an elongation at break of about 300% or more as determined in accordance with ASTM D2653-07(2018) at a temperature of about 23° C.
