Description

Technical Field

[0001] This utility model relates to a high-strength, high-color-fastness wool yarn, belonging to the field of wool yarn technology. Background Technology

[0002] Warm-retaining yarns typically have a fluffy structure that traps still air and impedes heat exchange, thus achieving a warming effect. Wool fiber, as a widely used animal protein fiber, has excellent warmth retention and is a common fiber material used to make warm-retaining yarns. However, warm-retaining yarns made from wool, due to their fluffy structure, suffer from insufficient strength. Furthermore, when colored yarns are needed, the wool must be dyed, but dyed wool fibers have low colorfastness. Therefore, how to produce a high-strength, high-colorfastness wool yarn with good warmth retention has become a problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength, high-color-fastness wool yarn that has higher strength and color fastness than pure wool yarn.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] The present invention relates to a high-strength, high-color-fastness wool yarn, comprising a core yarn, wherein a wrapping yarn layer is spirally wrapped around the outside of the core yarn, and a first covering fiber layer is wrapped around the outside of the wrapping yarn layer.

[0006] The core yarn includes flax yarn;

[0007] The wrapping yarn layer comprises wool / PVA blended yarn;

[0008] The first coating fiber layer is solution-dyed acrylic fiber.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the solution-dyed acrylic fiber is hollow.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the wrapping yarn layer also includes cotton / PVA blended yarn.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the core yarn also includes graphene-modified nylon filaments twisted together with the flax yarn.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: a second covering fiber layer is provided between the wrapping yarn layer and the first covering fiber layer; the second covering fiber layer is copper-modified nylon fiber.

[0013] The beneficial effects of this utility model are as follows: The high-strength, high-colorfastness wool yarn involved in this utility model uses linen yarn as the core yarn, which can improve the breaking strength of the yarn and the rigidity of the wool yarn, resulting in fabrics with better crispness. The wool / PVA blended yarn used undergoes PVA hydrolysis after hot water treatment, thereby improving the fluffiness of the wool yarn and enhancing its warmth retention. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the cross-sectional structure of the high-strength, high-colorfastness wool yarn involved in Example 1;

[0015] Figure 2 This is a schematic diagram of the cross-sectional structure of the high-strength, high-colorfastness wool yarn involved in Example 2. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] Combination Figure 1 This embodiment will be described in detail below. The high-strength, high-colorfastness wool yarn involved in this embodiment includes a core yarn 1, with a wrapping yarn layer 2 spirally wrapped around the outer side of the core yarn 1, and a first covering fiber layer 3 covering the outer side of the wrapping yarn layer 2.

[0019] The core yarn 1 comprises flax yarn, specifically 16 count. Using flax yarn as core yarn 1 improves the breaking strength of the wool yarn. Furthermore, the higher stiffness of the flax yarn enhances the stiffness of the wool yarn. Knitted fabrics made using this wool yarn exhibit better shape retention and stiffness.

[0020] The wrapping layer 2 comprises a wool / PVA blended yarn; PVA fibers that are water-soluble in water at 70°C are selected. The use of PVA fibers allows the PVA fibers to dissolve when the wool yarn is treated in hot water, thus leaving cavities in the PVA fibers and giving the wool yarn good warmth retention.

[0021] The first coating fiber layer 3 is solution-dyed acrylic fiber. Solution dyeing is a material processing technology that directly prepares colored fibers by adding a colorant to the spinning solution or before the spinneret, and through processes such as mixing and filtration. The solution-dyed acrylic fibers used have higher color fastness than dyed fibers.

[0022] Furthermore, the solution-dyed acrylic fibers are hollow. Hollow solution-dyed acrylic fibers have better warmth retention.

[0023] Example 2

[0024] Combination Figure 2 This embodiment will be described in detail below. The high-strength, high-colorfastness wool yarn involved in this embodiment differs from that in Embodiment 1 in that a second covering fiber layer 4 is provided between the wrapped yarn layer 2 and the first covering fiber layer 3; the second covering fiber layer 4 is copper-modified nylon 6 fiber. Oleic acid is used to coat nano-spherical copper antibacterial agents, which are then blended with a polyamide 6 (PA6) matrix and extruded to obtain antibacterial PA6 chips. These chips are then melt-spun into single components and melt-spun into composite fibers to obtain copper-modified antibacterial PA6 fibers. The oleic acid-coated spherical copper antibacterial agent exhibits good dispersibility and compatibility with the PA6 matrix. The antibacterial and anti-mite PA6 chips demonstrate good thermal stability and spinnability. The copper-modified antibacterial and anti-mite PA6 fibers exhibit uniform color, a fiber yield of up to 88%, and a breaking elongation of 29.95% and a breaking strength of 4.43 cN / dtex for the copper-modified PA6 stretched textured yarn. After 50 washes, the copper-modified antibacterial and anti-mite PA6 fiber showed an antibacterial rate of over 99% against Candida albicans, Staphylococcus aureus, and Escherichia coli. The fabric achieved a mildew resistance level of 0 and a mite repellency rate of 89%, demonstrating highly efficient and durable antibacterial, mildew-proof, and anti-mite properties.

[0025] Another difference from Example 1 is that the wrapping yarn layer 2 also includes cotton / PVA blended yarn. The use of PVA fiber can improve bulkiness, and the cotton fiber used is antibacterial cotton fiber.

[0026] Another difference from Example 1 is that the core yarn 1 also includes graphene-modified nylon filaments twisted together with the flax yarn. Graphene-modified nylon filaments are prepared by using graphene as a functional material, blending it with water-soluble polyurethane to obtain a functional coating agent, and then coating it onto the surface of the nylon filament using a continuous solution impregnation coating technology.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
