Description

Technical Field

[0001] The utility model relates to an antistatic semi-worsted wool blended knitting yarn, belonging to the technical field of textile yarns. Background Art

[0002] As a natural protein fiber, wool fiber is widely used in clothing fabrics, especially high-end clothing fabrics. Since wool fiber fabrics are relatively expensive, some acrylic fibers are usually used to replace some wool fibers to reduce the price of wool fiber fabrics. However, the use of acrylic fibers will cause static electricity in the fabric during use, which will reduce the comfort of wool-containing fabrics. The semi-worsted spinning process is an innovative technology that breaks through professional limitations and is between worsted spinning and carded wool spinning. Compared with the worsted spinning process, it has a shorter production process and produces more fluffy, soft and full yarns. Compared with the wool spinning process, it has the characteristics of high yarn count, uniform yarn, smooth surface, and fine fabric. As for knitting yarn, since the yarn has more bending and friction during the weaving process, the yarn is required to have good stretchability, smooth surface, and not easy to pilling. How to prepare an antistatic semi-worsted wool blended knitting yarn has become a problem to be solved. Utility Model Content

[0003] The utility model aims to provide an antistatic semi-worsted wool blended knitting yarn, which has the effects of anti-pilling and anti-static.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0005] The utility model relates to an antistatic semi-worsted wool blended knitting yarn, comprising an elastic core yarn and a wrapping yarn layer wrapped around the outer side of the elastic core yarn, wherein the wrapping yarn layer comprises wool semi-worsted yarn, anti-pilling acrylic fiber yarn and antistatic fiber yarn; the wool semi-worsted yarn uses mercerized wool fiber, and sericin is attached to the surface of the mercerized wool fiber.

[0006] On the basis of the above solution and as a preferred solution of the above solution: the elastic core yarn is elastic filament.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the antistatic fiber yarn is polyamphetamine modified wool fiber yarn.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the elastic core yarn also includes a Sorona fiber yarn twisted with the elastic filament.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the mercerized wool fiber is inlaid with far-infrared antibacterial functional crystals.

[0010] The beneficial effects of the utility model are as follows: the antistatic semi-worsted wool blended knitting yarn involved in the utility model has good elasticity due to the elastic core yarn used, which meets the stretchability requirements of the knitting yarn. The antistatic fiber yarn used gives the knitting yarn antistatic properties, avoiding the static electricity phenomenon generated by the use of acrylic fiber. The wool semi-worsted yarn formed by the anti-pilling acrylic fiber yarn and the mercerized wool with sericin attached makes the knitting yarn anti-pilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic structural diagram of the antistatic semi-worsted wool blended knitting yarn involved in Example 1.

[0012] The markings in the figure are as follows: 1-elastic core yarn; 2-wrapping yarn layer; 21-wool semi-worsted yarn; 22-anti-pilling acrylic fiber yarn; 23-antistatic fiber yarn. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Embodiment 1

[0015] Combination Figure 1 The present embodiment is described in detail. The antistatic semi-worsted wool blended knitting yarn involved in the present embodiment comprises an elastic core yarn 1 and a wrapping yarn layer 2 wrapped around the outer side of the elastic core yarn 1. The wrapping yarn layer 2 comprises a wool semi-worsted yarn 21, an anti-pilling acrylic fiber yarn 22 and an antistatic fiber yarn 23.

[0016] The wool semi-worsted yarn 21 uses mercerized wool fibers, and sericin is attached to the surface of the mercerized wool fibers. Mercerized wool is soft and smooth, has a cashmere-like feel, silk-like luster, and has excellent characteristics such as shrinkage resistance, machine washability, and anti-pilling. In addition, the sericin attached to the surface can make the contacting mercerized wool bonded to each other, thereby improving its anti-pilling performance. The sericin used is sericin removed from silk, which can be used for bonding and finishing between fibers, thereby reducing the slippage of wool fibers in wool yarn. Specifically, the wool yarn is soaked in sericin solution and then soaked in glutaraldehyde solution and dried. When the cashmere yarn is soaked in sericin solution, the sericin solution can be evenly distributed in the cashmere yarn. Under the action of interfacial tension, the sericin solution is more likely to be concentrated at the position where the fibers contact and cross each other, forming a point-like structure model similar to the chemical bonding method non-woven fabric. Therefore, after drying, the contacting wool fibers will be bonded by sericin, thereby reducing the slippage of the wool fibers from the yarn.

[0017] Furthermore, the elastic core yarn 1 is an elastic filament, which is spandex filament in this embodiment.

[0018] Further, the antistatic fiber yarn 23 is a polyphenylene amine modified wool fiber yarn. The wool fiber yarn modified by polyphenylene amine has a smooth surface and a scale structure coated with polyphenylene amine, which can effectively reduce friction during spinning and use and avoid shrinkage.

[0019] Embodiment 2

[0020] The antistatic semi-worsted wool blended knitting yarn involved in this embodiment is different from the first embodiment in that the elastic core yarn 1 also includes a Sorona fiber yarn twisted with the elastic filament. The Sorona fiber used in the Sorona fiber yarn has excellent elasticity and resilience. The Sorona fiber yarn is twisted with the elastic filament and also has good elasticity, and can avoid the weakening or even loss of elasticity of the knitting yarn after one of the elastic filament or Sorona fiber yarn breaks.

[0021] Furthermore, the mercerized wool fiber is inlaid with far-infrared antibacterial functional crystals. A certain amount of zinc, silicon, magnesium, and calcium compounds (one or more) are dissolved in water to obtain solution ①, butyl phthalate and anhydrous ethanol are mixed at a volume ratio of 1:50 to obtain solution ②, solution ① is poured into a burette, a beaker with solution ② is placed in a DF-101S heat-collecting constant temperature magnetic stirrer water bath, and stirred, solution ① is slowly dripped into solution ② at a speed of about 30 to 50 drops / min, and after the dripping is completed, solution ③ is obtained, urea with a mass fraction of 0.1% to 1.0% is slowly dripped into solution ③, mixed evenly to obtain a colorless and transparent mixed solution, added to a reactor, reacted at a high temperature of 130 to 180°C for 6 to 15h, cooled to room temperature and placed for 5 to 10h to obtain a milky white slurry; a small amount of macromolecular surface modifier is added, ground in a star-shaped ball mill for several hours, and then subjected to ultrasonic oscillation for 15 minutes to obtain a surface-modified far-infrared antibacterial functional crystal dispersion slurry. The wool fiber is immersed in a dispersed slurry of infrared antibacterial functional crystals, and then subjected to a series of operations such as drying to form a wool fiber with far-infrared antibacterial functional crystals embedded on the surface, which has an antibacterial effect.

[0022] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work.
