Composite yarn for high-cutting-resisting-degree fabric

Abstract

The invention discloses composite yarn for high-cutting-resisting-degree fabric. The composite yarn comprises a core material filament and a covering layer. The yarn is characterized in that a dust cage spinning technology is used, so that short fibers in the covering layer cover the outer face of the core material filament in the vertical direction. According to the composite yarn for the high-cutting-resisting-degree fabric, the dust cage spinning technology is used, high-content inorganic fiber filament core materials are spun, an outer high-intensity short fiber shell layer covers the core materials by 100% to form core spun yarn, the core spun yarn can be subjected to independent knitting or composite double-layer knitting with spandex covering yarn to form the high-cutting-resisting-degree fabric, and the fabric can reach the cutting-resisting fifth level by the American standard. According to the structure of the composite core spun yarn, the inner portion is tight, the outer portion is loose, and fabric handfeel is soft and comfortable. The fabric can be widely used for products which need to provide high-level cutting protection, for example, various products of space flight and aviation seat linings, gloves and linings thereof, aprons, oversleeves and the like.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a composite yarn for high-cut-resistant fabrics. Background technique [0002] Fabrics used for cut-resistant protection generally require the use of high-strength, high-modulus yarns, usually with high rigidity and hardness, such as para-aramid filament or short fiber yarn and ultra-high Molecular weight polyethylene fiber filament and other related products, these fabrics tend to feel rough and poor in comfort. In particular, sometimes it is necessary to improve the yarn to further improve the cut resistance of the fabric, such as core-spun or coated glass fiber, stainless steel fiber and other rigid fibers, and it is difficult to cover completely, making the fabric more rough and uncomfortable. [0003] CN104532431 reports that in order to reduce the exposure of the core-spun glass fiber, two layers of inner and outer layers are used for reverse coating. First, the 100d glas...

Problems solved by technology

But there are following problems in this invention technology: (1) low-twisted yarn has abundant hairiness, higher requirement for subsequent weaving process, and high end-breakage rate; (2) low twist is unfavorable for the design of core-spun yarn, and further It is less likely to improve the cut resistance of the fabric; (3) The appearance of the high linear density staple fiber yarn fabric is relatively rough, and it also offsets part of the comfort of the fabric

The technology of this invention actually uses the higher denier monofilament para-aramid to improve the cutting resistance of the fabric to offset the decrease in the cutting resistance due to the introduction of lubricating fibers, but the introduction of a higher proportion of lubricating fibers with low strength and low modulus, There is still a high risk to the maintenance of fabric cut resistance
