Abstract
A filamentary core for an elastic composite yarn, particularly for an elastic textile composite yarn, comprising at least two elastic performance filaments, wherein each of the at least two elastic performance filaments is capable of being stretched at least about 2 times its package length and has at least 90% up to 100% elastic recovery after having being released from a stretching 2 times its package length.
Claims23
A filamentary core for an elastic composite yarn, comprising:
- at least two elastic performance filaments, and
- at least one inelastic control filament being incapable of being stretched beyond a maximum length without permanent deformation, said maximum length being less than 1.5 times of its package length, wherein:
- each of the at least two elastic performance filaments has a different elastic behavior, and
- each of the at least two elastic performance filaments is configured to:
- be stretchable at least about 2 times its package length, and
- have at least 90% up to 100% elastic recovery after having being released from a stretching of 2 times its package length.
3 more elements
A method for producing a filamentary core, comprising:
- providing separately at least two elastic performance filaments configured to be stretchable at least about 2 times its package length and have at least 90% up to 100% elastic recovery after having being released from a stretching 2 times its package length, each of the at least two elastic performance filaments having a different elastic behavior;
- and
- providing at least one inelastic control filament being incapable of being stretched beyond a maximum length without permanent deformation, said maximum length being less than 1.5 times of its package length.
