摘要： A thermoplastic elastomer-based monofilament yarn and a method of making a thermoplastic elastomer-based monofilament yarn are disclosed. The monofilament yarn comprises a filament that contains an axial core about which two or more lobes are radially disposed. The filament comprises a thermoplastic elastomer composition comprising a thermoplastic elastomer that 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. The yarn exhibits 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.

摘要： A thermoplastic elastomer-based multifilament yarn and a method of making a thermoplastic elastomer-based multifilament yarn are disclosed. The multifilament yarn comprises a first filament that is at least partially adhered to a second filament. The first filament and the second filament are each formed from a thermoplastic elastomer composition comprising a thermoplastic elastomer that 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. The yarn has a linear density of from about 1 to about 500 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.

摘要： 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.
