Description

Technical Field

[0001] The utility model relates to an anti-pilling semi-worsted cashmere yarn, belonging to the technical field of cashmere yarns. Background Art

[0002] Cashmere fiber, as a high-grade weaving raw material, is increasingly favored by consumers for its high-quality texture and good wearing performance. The fabrics made of cashmere yarn are soft to the touch, warm and comfortable to wear. However, because cashmere fibers are thin and soft, with a round cross-section, short length, less curl, and poor cohesion between fibers, cashmere fibers can easily slip out of the yarn. In addition, cashmere fibers have high strength and elongation and good elasticity. Once they slip out of the yarn and form pilling, they are not easy to break and are easy to entangle and pill. As the number of times they are worn increases, the number of times they are washed and rubbed also increases, which makes the pilling phenomenon of knitted fabrics or woven fabrics made of cashmere fibers more and more serious, affecting the wearability and appearance of the prepared clothing.

[0003] The product of semi-worsted yarn is between worsted and woolen, which is determined by its equipment configuration and the particularity of the raw materials used. In terms of equipment, cotton yarn technology and wool spinning technology are integrated, which is a spinning process formed by combining the front-end wool equipment with cotton spinning carding, drawing, woolen spinning and spinning machines, etc., and the back-end worsted winding, doubling and twisting equipment. In addition, semi-worsted yarn can be spun in the range of 27-102Nm, which can be used to prepare warm fabrics with coarser yarn counts, and can also meet the requirements of knitting and woven fabrics to produce high-end light fabrics.

[0004] How to prepare an anti-pilling semi-worsted cashmere yarn has become a problem to be solved. Utility Model Content

[0005] The utility model aims to provide an anti-pilling semi-worsted cashmere yarn. The wool in contact with each other in the cashmere semi-worsted yarn is bonded by sericin to reduce the occurrence of pilling.

[0006] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0007] The utility model relates to an anti-pilling semi-worsted cashmere yarn, comprising a core yarn and a first wrapped yarn layer spirally wrapped around the outer side of the core yarn, wherein the first wrapped yarn layer comprises anti-pilling acrylic yarn and cashmere semi-worsted yarn; sericin is attached to the surface of the cashmere fibers in the cashmere semi-worsted yarn.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the core yarn includes stretched wool yarn.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the wool fiber used in the stretched wool yarn is non-permanently set stretched wool.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: an antibacterial agent is attached to the surface of the acrylic fiber in the anti-pilling acrylic yarn.

[0011] On the basis of the above solution and as a preferred solution of the above solution: a second wrapping yarn layer is arranged on the outer side of the first wrapping yarn layer; the second wrapping yarn layer is cashmere worsted yarn.

[0012] The beneficial effects of the utility model are as follows: the anti-pilling semi-worsted cashmere yarn of the utility model adopts a core-spun structure, which can increase the strength and diameter of the yarn, so that the yarn can be used to prepare heavy fabrics in autumn and winter. The anti-pilling acrylic yarn used can be used to replace wool fiber to reduce costs. The sericin attached to the surface of the cashmere fiber in the cashmere semi-worsted yarn can make the contacting cashmere fibers bonded, thereby reducing the probability of the cashmere fiber slipping off the yarn and reducing pilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a schematic structural diagram of the anti-pilling semi-worsted cashmere yarn involved in the second embodiment.

[0015] The markings in the figure are as follows: 1-core yarn; 2-first wrapping yarn layer; 3-second wrapping yarn layer; 21-anti-pilling acrylic yarn; 22-cashmere semi-worsted yarn. DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] Combination Figure 1 The present embodiment is described in detail. The anti-pilling semi-worsted cashmere yarn involved in the present embodiment comprises a core yarn 1 and a first wrapping yarn layer 2 spirally wrapped around the outer side of the core yarn 1, wherein the first wrapping yarn layer 2 comprises an anti-pilling acrylic yarn 21 and a cashmere semi-worsted yarn 22; and sericin is attached to the surface of the cashmere fibers in the cashmere semi-worsted yarn 22.

[0019] The sericin used in this embodiment is sericin removed from silk, which can be used for bonding and finishing between fibers, thereby reducing the slippage of cashmere fibers in cashmere yarn. Specifically, the cashmere 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 concentrate 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 cashmere fibers will be bonded by sericin, thereby reducing the slippage of the cashmere fibers from the yarn.

[0020] Furthermore, the core yarn 1 includes stretched wool yarn. The wool fiber used in the stretched wool yarn is non-permanently set stretched wool. Stretched and refined wool is a fiber with a very special shape. The fineness and length of the wool are changed after stretching and thinning. In the subsequent shaping process, through innovative shaping technology, the shape of the stretched and refined wool can be permanently fixed, or the shape of the stretched and refined wool can be temporarily fixed, that is, non-permanently set, and deformed when encountering high temperature and humidity in the future. The wool fiber used in this embodiment is non-permanently qualitatively stretched. The fabric prepared by the yarn is subjected to high temperature and high humidity finishing during post-finishing to allow the fiber to shrink, thereby increasing the density of the fabric and increasing the warmth retention effect.

[0021] Embodiment 2

[0022] Combination Figure 2 , this embodiment is described in detail. The anti-pilling semi-worsted cashmere yarn involved in this embodiment is different from the first embodiment in that an anti-pilling acrylic fiber in the anti-pilling acrylic fiber yarn has an antibacterial agent attached to the surface of the acrylic fiber, which can improve the antibacterial effect of the anti-pilling semi-worsted cashmere yarn.

[0023] Another difference from the first embodiment is that a second wrapping yarn layer 3 is arranged outside the first wrapping yarn layer 2; the second wrapping yarn layer 3 is cashmere worsted yarn, and sericin is also attached to the surface of the cashmere fibers in the cashmere worsted yarn.

[0024] 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. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
