Title:
SPUN YARN, METHOD FOR PRODUCING SAME, AND FABRIC COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/004710
Kind Code:
A1
Abstract:
The present invention relates to a spun yarn which contains from 15% by mass to 85% by mass of polypropylene fibers and from 15% by mass to 85% by mass of polyester fibers, said spun yarn being composed of a non-twisted fiber group in a non-twisted state and a winding fiber group that is wound around the non-twisted fiber group, while having a porosity of 60% or less. This spun yarn is able to be produced by: preparing a sliver that contains from 15% by mass to 85% by mass of polypropylene fibers and from 15% by mass to 85% by mass of polyester fibers in vortex air fine spinning; supplying the sliver to a draft zone for drafting; spinning the sliver at a nozzle pressure of from 0.4 MPa to 0.65 MPa at a spinning speed of from 250 m/min to 400 m/min; and taking up the thus-spun yarn. Consequently, the present invention provides: a spun yarn which enables the achievement of a fabric that has anti-pilling properties as well as good water-absorbing and quick-drying properties, while favorably preventing evaporative cooling after perspiration; a method for producing this spun yarn; and a fabric which comprises this spun yarn.
