Embodiment 1

[0054] Embodiment one: the specification of stainless steel wire is 32 μm, and the interlining core yarn is polyester fully drawn yarn (Fullydrawnyarn, FDY), 75D / 36f (75D refers to that the total density of multifilament is 75 deniers; Denier is linear density The unit refers to the weight in grams of 9000 meters long fiber or yarn when the moisture regain is determined), 36F means that the 75D yarn is composed of 36 monofilaments), the first outer wrapping yarn is polyester DTY, 100D / 36f, wrapping twist 800 twists / m, wrapping twist direction Z twist; second outer wrapping yarn is pure cotton 60S combed yarn, wrapping twist 544 twists / m, wrapping twist direction S twist. 60S means that the linear density of the yarn is 60 pounds, and the British branch is generally represented by S. The British branch is the unit of linear density of the British yarn, which refers to the multiple of 840 yards of the length of a 1-pound yarn at the British standard moisture regain. The covered...

Embodiment 2

[0055] Embodiment 2: The stainless steel wire specification is 32 μm, the interlining core yarn is a blended yarn with a corn / cotton blending ratio of 30 / 70, the linear density is 40S, the first outer wrapping yarn is polyester DTY, 100D / 36f, and the wrapping twist is 1000 twists / m, wrapping twist to Z twist; the second outer wrapping yarn is 70D / 24f nylon DTY, wrapping twist 680 twist / m, wrapping twist to S twist. The covered yarn is wrapped with polyester and nylon, has good abrasion resistance and comfort, and is suitable for making antistatic and radiation-proof work clothes fabrics that are not worn next to the body.

[0056] In summary, the present invention takes the hollow spindle covered spinning machine as the processing equipment, and uses a non-twist / low-twist filament yarn (FDY) or The short-spun yarn is the "interlining core" and the stainless steel wire, which are respectively combined under appropriate tension and passively unwound, and together act as the cor...

Abstract

The present invention discloses a stainless steel wrapping yarn and a processing method thereof. The stainless steel wrapping yarn comprises a stainless steel wire; the stainless steel wire and a lining yarn are combined together to form a twin-core yarn; the diameter of the lining yarn is greater than the diameter of the stainless steel wire; outer wrapped yarns are disposed outside the twin-core yarn; the outer wrapped yarns comprise the first outer wrapped yarn and the second outer wrapped yarn; the first outer wrapped yarn and the second outer wrapped yarn are wound outside the twin-core yarn and wrap the twin-core yarn; and winding directions of first outer wrapped yarn and the second outer wrapped yarn are opposite. The lining yarn is introduced to compose the twin-core yarn with the stainless steel wire, then the twin-core yarn is intercrossed and wound in positive and negative directions for two times, the stainless steel wrapping yarn of a lining-wrapped structure is formed, so that the problems that wrapping of a stainless steel functional yarn is not sealed and a core is exposed, performance of stainless steel fiber is degraded due to twisting and torsion, slip is performed between a stainless steel core wire and a wrapping component core sheath, and the yarn is arched when stretched and the like are solved.

Description

technical field [0001] The invention relates to a covered yarn and a processing method thereof, in particular to a stainless steel covered yarn and a processing method thereof. Background technique [0002] Stainless steel fiber is a micron-sized filament made of 304, 304L or 316, 316L stainless steel wire as raw material, and processed by monofilament drawing method, cluster drawing method and other methods. Due to the special material and scale, stainless steel fiber has eight functions such as anti-electromagnetic wave, anti-static, conductive, high temperature resistance, cutting resistance, abrasion resistance, filterability, sound absorption and insulation, and can be widely used in the production of anti-static work clothes (electronic component production, Gas station electrostatic hazard place), anti-static filter cloth (filter charged dust), anti-radar reconnaissance cover cloth (tank, cannon camouflage), anti-electromagnetic radiation clothing (personal protection...
