Problems solved by technology

[0005] 1. Due to the high twist, as a denim warp yarn, it will be entangled with each other during drawing and sizing, making warp separation difficult, increasing end breaks, seriously affecting drawing and sizing speed, greatly increasing warp loosening, and seriously affecting fabrics Yield
[0006] 2. Due to the high twist of the core wire, the burnt-out garment is in a loose state, and the core wire exposed by the burnt-out part will twist and slip, which seriously affects the appearance of the garment

Abstract

The invention discloses low- and zero-twist cotton nylon and polyester dual core-spun compound yarn which comprises a yarn I, a yarn II and a core yarn, wherein the yarn I and the yarn II respectivelyrotate in S direction and Z direction to envelop the core yarn in an intersection manner; the core yarn has the following two types:(I) the core yarn is 1F-48F chinlon filament yarn or polyester filament yarn; (II) the core yarn consists of two layers of thick yarns and two layers of thin yarns, and the thick yarns and the thin yarns are alternately stacked. The dual core-spun compound yarn serves as warp yarn of jean fabric; in warp drawing and sizing dyeing, the twist is very low between the yarns, and thus the yarns are not twisted and broken. The speed of warp drawing and sizing dyeing isincreased, and loose warp is greatly reduced in weaving; since the core yarn has low or zero twist, after burnout treatment on jeans wear, the fact that the jeans wear get loose, and the core yarns twist or slide to influence the beauty, and the fact that the cotton yarns burnt out at the holes of beggar dress (breezy outfit) droop and thus influence the dress beauty are avoided by adopting the dual core-spun yarn, and the dress is tidier and more beautiful.

Description

technical field [0001] The invention relates to the technical field of strands, in particular to a low, untwisted cotton-nylon and polyester double-cored strand. Background technique [0002] The traditional ply yarn is usually combined with double-ply cotton yarn (or core yarn, usually spandex) in the same twist direction, and then twisted by a two-for-one twister or an upper doubling machine, so that the processed strand has a high twist. [0003] Currently on the market, double-strand cotton wraps low-F-number nylon or polyester to achieve extremely low-twisted or untwisted three-strand yarn, and no manufacturer produces it. [0004] If the same-twist yarn is used to add low F-number nylon or polyester to be combined first and then twisted on a two-for-one twister, the core yarn will participate in the twisting, and the core-spun strands processed in this way have the following disadvantages: [0005] 1. Due to the high twist, as a denim warp yarn, it will be entangled w...
