Multi-core core-spun yarn and double-twist yarn and core-spun yarn thereof, and glove and fabric woven with the multi-core core-spun yarn

Abstract

The invention relates to the technical field of core-spun yarns, in particular to a multi-core core-spun yarn, comprising a core layer and a covering layer. The sectional outline of the core layer is approximately circular, the sectional outline of the core layer is 4.5-750 Mum in outer diameter, the core layer includes two or more core yarns that are hard core yarns determined via ISO2062 method to be less than 50% in elongation at break, and covering fiber of the covering layer is wound outside the core layer by means of ring-spinning core spinning process. The multi-core core-spun yarn of the invention is of core-spun structure with multiple thin core yarns converted from traditional single-core-yarn core-spun structure, space is provided among the multiple thin core yarns for movement, the small core yarns are better than the thick hard core yarns in softness, the problem that the hard core-spun yarn has stiff handle is improved structurally, the structure of soft multiple thin core yarns is better in flexural resistance than that of a single thick core yarn, and product quality is improved significantly.

Description

technical field [0001] The invention relates to the technical field of core-spun yarns, in particular to a multi-core core-spun yarn and its two-fold twisted yarn, the core-spun yarn and gloves and fabrics woven therefrom. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a composite yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. [0003] Since the beginning of the 21st century, with the rapid development of the textile and garment industry and the continuous expansion of consumer groups' pursuit of high-end and brand names, the market's demand for high-strength core-spun sewing threads has also continued to increase, and its quality requirements have also become higher and higher. . In order to improve the properties of yarns such as deformation resistance and shrinkage resistance, the mar...

AI Technical Summary

Problems solved by technology

In the prior art, hard filaments such as glass filaments / metal wires / basalt filaments have been used as core yarns, but when these hard filaments are used as core yarns, the core yarns are prone to breakage or exposure, which affects The strength and comfort of the final product, as well as the reduced service life and safety hazards caused by discomfort

[0004] In addition, in the prior art, a single hard filament is generally used as the core yarn, and the diameter of the core yarn is about 4.5-750 μm. The core-spun structure of this core yarn often brings about the problem of stiff hand feeling, which affects this kind of yarn. Comfort of core-spun fabrics
