Problems solved by technology

[0002] Usually when we choose clothing, we pay attention to the surface quality of the clothing fabric, such as whether the fabric feels soft and comfortable, whether it will generate static electricity, moisture absorption and breathability, etc., and these often depend on the performance of the yarn itself. Now There are many types of textile yarns, and different yarns have different properties. The current yarns are generally made of cotton, hemp and other materials, so that the mechanical strength and bending resistance of the current yarns are generally relatively high. Poor, unable to meet people's needs for high-strength yarns, and the current antibacterial and bactericidal effects of yarns are poor, unable to meet people's needs for strong antibacterial and bactericidal, as disclosed in the Chinese invention patent application (application number: 201610736647.X) An antibacterial fabric with good durability and its manufacturing process are disclosed. The fabric is an antibacterial fabric composed of fibers. The antibacterial agent is added before dyeing in the subsequent shaping process of the fabric, wherein the antibacterial agent consists of seaweed, allantoic Vegetarian and Inonotus obliquus

preparation example Construction

[0024] A preparation method of composite yarn, comprising the following steps:

[0025] Step 1: the yarn core 8 is obtained through cleaning, carding, drawing, combing, drawing, roving, spun yarn, winding, doubling, and post-processing in sequence;

[0026] Step 2: the silver-plated fiber 3: the fiber substrate is chemically silver-plated or vacuum-plated with silver to form a silver-plated fiber;

[0027] Step 3: Ply and blend silver-plated fiber 3, spun fiber 4, and bamboo charcoal fiber 5 to make blended yarn 1;

[0028] Step 4: The simulated silk polyester composite yarn 2: two types of fibers, the pre-oriented POY yarn 6 and the fully drawn FDY yarn 7, are networked to form a network yarn, and then twisted and heat-shrinked to shape;

[0029] Step 5: Plying the blended yarn 1 with the imitation silk polyester composite yarn 2 and reversely twisting them on the yarn core 8 to form a composite yarn.

[0030] In order to further illustrate the preparation method, two speci...

Embodiment 1

[0031] Embodiment 1: the spun fiber 4 of the silver-plated fiber 3,89% and 10% bamboo charcoal fiber 5 of weight ratio 1% are mixed and loosened and made blended yarn 1 through compact siro spinning spinning process, blended Yarn 1 and imitation silk polyester composite yarn 2 are plied and reversely twisted to form a composite yarn on the yarn core 8, in which the silver-plated fiber 1 has good antibacterial performance and antibacterial rate, because the heat shrinkage rate of POY filament is obvious The ground is higher than the FDY yarn, the POY yarn shrinks, and the length becomes shorter, causing the FDY yarn to protrude and deform, and cover the surface of the composite fiber. The silk-like polyester composite yarn 2 has better elasticity, which improves the elasticity of the composite yarn and Tensile strength, bamboo charcoal fiber 5 has better deodorizing and sterilizing functions, and through the above processing, a composite yarn with stable structure, good luster, ...

Embodiment 2

[0032] Embodiment 2: after the silver-plated fiber of 3% by weight, the spinning fiber of 87% and the bamboo charcoal fiber of 10% are mixed and loosened, the blended yarn is made through the compact siro spinning process, and the blended yarn 1 and The imitation silk polyester composite yarn 2 is plied and reversely twisted to form a composite yarn on the yarn core 8, in which the silver-plated fiber 1 has better antibacterial performance and antibacterial rate, because the heat shrinkage rate of POY silk is significantly higher than that of FDY Filament, POY filament shrinks, the length becomes shorter, causing FDY filament to protrude and deform, and cover the surface of the composite fiber. The simulated silk polyester composite yarn 2 has better elasticity, which improves the elasticity and tensile capacity of the composite yarn. Bamboo charcoal fiber 5 has better deodorizing and sterilizing functions, and through the above-mentioned processing, a composite yarn with stabl...

Abstract

The invention relates to composite yarn and a preparation method thereof. The composite yarn is formed by stranding blended yarn and silk-like composite polyester yarn, the blended yarn and the silk-like composite polyester yarn are wound on a yarn core in a reverse twisting mode, the blended yarn is formed by blending silver-plated fibers, spun fibers and bamboo charcoal fibers, and the silk-likecomposite polyester yarn is composed of pre-oriented yarn POY and fully drawn yarn FDY. According to the preparation method of the composite yarn, the blended yarn formed by blending the silver-plated fibers, spun fibers and bamboo charcoal fibers and the silk-like composite polyester yarn formed by carrying out twisting and thermal shrinkage shaping on interlaced yarn generated by the pre-oriented yarn POY and the fully drawn yarn FDY are wound on the yarn core in the reverse twisting mode; the composite yarn formed by compounding and twisting multiple kinds of yarn has better elasticity, air permeability, antibacterial ability, deodorization ability and better gloss, and meets higher requirements of people on textile products.
