Description

Technical Field

[0001] The utility model relates to an antibacterial woolen cashmere and wool blended yarn, belonging to the technical field of cashmere and wool blended yarns. Background Art

[0002] With the improvement of modern living standards, people have put forward more and newer requirements for knitted clothing. Knitted fabrics for clothing should not only be fashionable, high-grade and comfortable, but also have diversified functions such as antibacterial, health care, warmth retention, easy care and easy maintenance. As a necessity in people's daily life, textiles often come into direct or indirect contact with the human body during use, and there are special requirements for their antibacterial properties. Especially for wool and cashmere products, due to the microporous structure and keratin composition of wool fibers, it is extremely easy to provide the moisture, nutrients and living space required for bacterial growth. And for the fabrics prepared from wool and cashmere yarns by knitting method, since knitting is formed by looping and knitting of yarns, it has good softness, but the knitted fabrics have deficiencies in terms of stiffness. How to prepare an antibacterial woolen cashmere and wool blended yarn that has a certain degree of stiffness on the premise of having warmth retention and antibacterial properties. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an antibacterial woolen cashmere and wool blended yarn. The use of hemp fiber yarn makes the blended yarn have a certain degree of stiffness, and the antibacterial woolen yarn used provides a certain antibacterial effect.

[0004] To solve the above technical problems, the purpose of the utility model is realized as follows:

[0005] An antibacterial woolen cashmere and wool blended yarn according to the utility model includes a core yarn, and a first yarn and a second yarn spirally wound around the outside of the core yarn in opposite directions;

[0006] The core yarn includes a hemp fiber yarn and an antibacterial chemical fiber filament twisted together; the first yarn is an antibacterial woolen yarn; the second yarn is a cashmere fine-spun yarn.

[0007] On the basis of the above solution and as a preferred solution of the above solution: the hemp fiber yarn is a flax fiber yarn or a ramie fiber yarn.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the antibacterial chemical fiber filament is an antibacterial polyester filament or an antibacterial polyamide filament.

[0009] On the basis of the above solution and as a preferred solution of the above solution: the antibacterial polyamide filament is a nano-zinc oxide modified polyamide 6 filament.

[0010] On the basis of the above solution and as a preferred solution of the above solution: titanium dioxide is attached to the surface of the cashmere fine-spun yarn.

[0011] The beneficial effects of the present utility model are as follows: An antibacterial blended yarn of rough-spun cashmere and wool according to the present utility model adopts a hemp fiber yarn in the core yarn. By utilizing the good rigidity of the hemp fiber, the knitted fabric prepared from this yarn has a stiffness. The antibacterial wool rough-spun yarn used has a fluffiness, which improves the heat preservation effect and endows the yarn with antibacterial properties. The fine-spun cashmere yarn used can reduce the pilling of this blended yarn. Description of the Drawings

[0012] Figure 1 It is a schematic structural view of the antibacterial blended yarn of rough-spun cashmere and wool according to the first embodiment.

[0013] The markings in the figure are explained as follows: 1 - core yarn; 2 - first yarn; 3 - second yarn. Detailed Embodiment

[0014] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0015] First Embodiment

[0016] Combined with Figure 1 , this embodiment will be described in detail. An antibacterial blended yarn of rough-spun cashmere and wool according to this embodiment includes a core yarn 1 and a first yarn 2 and a second yarn 3 that are helically wound around the outside of the core yarn 1 in opposite directions. The first yarn 2 and the second yarn 3 are wrapped around the outside of the core yarn 1 in opposite directions to form a yarn with a specific structure. If the first yarn 2 is helically wound in the clockwise direction, then the second yarn 2 is wound in the counterclockwise direction. Or the opposite setting is also possible.

[0017] The core yarn 1 includes a hemp fiber yarn and an antibacterial chemical fiber filament that are twisted together. The hemp fiber yarn is a linen fiber yarn or a ramie fiber yarn. In this embodiment, it is selected as a linen yarn. The linen yarn is relatively stiff, which can improve the stiffness of this blended yarn, so that the knitted fabric prepared from this blended yarn has a certain stiffness, and the fabric can be suitable for clothing such as coats.

[0018] Furthermore, the antibacterial chemical fiber filament is an antibacterial polyester filament or an antibacterial nylon filament. In this embodiment, it is selected as an antibacterial nylon filament, and the antibacterial nylon filament is a nano-zinc oxide modified nylon 6 filament. Specifically, the nano-zinc oxide modified nylon 6 filament is prepared by the masterbatch method in the co-blending spinning method. Zinc oxide is added to nylon 6 chips, and an antibacterial masterbatch containing zinc oxide is prepared through a screw extruder. Then, the antibacterial masterbatch and nylon 6 chips are fully mixed and put into a hopper, and the nano-zinc oxide modified nylon 6 filament is prepared by melt spinning.

[0019] The first yarn 2 is an antibacterial woolen yarn. The antibacterial woolen yarn is prepared by a woolen spinning process using antibacterial wool and has antibacterial function, so that the blended yarn has antibacterial effect. The woolen yarn has a fluffy characteristic, which can improve the heat preservation effect.

[0020] The second yarn 3 is a cashmere worsted yarn. The cashmere worsted yarn is prepared by a worsted spinning process using cashmere. The yarn is tight, which can reduce the occurrence of pilling of the blended yarn.

[0021] Furthermore, titanium dioxide is attached to the surface of the cashmere worsted yarn. When textile fabrics contain substances such as proteins or fats, microorganisms can easily reproduce. The toxins secreted by bacteria and molds can volatilize unpleasant odors and can decompose fibers into food, causing fiber damage. Titanium dioxide attached to the surface of the cashmere worsted yarn is a nano-scale photocatalytic semiconductor material with photocatalytic function. When titanium dioxide is excited by ultraviolet light and light, a large number of electrons are generated. These electrons react with water and oxygen adsorbed on the fabric surface to generate highly oxidizing hydroxyl radicals. The hydroxyl radicals can efficiently degrade harmful gases in the air, destroy the cell membranes of bacteria and the proteins of viruses, and efficiently kill a variety of bacteria (such as Escherichia coli, Staphylococcus aureus, influenza virus, etc.). The antibacterial rate reaches 99.99%. It can also decompose organic pollutants such as toxins and musty odors released by bacteria or molds into harmless carbon dioxide and water through oxidation-reduction reactions, until it has the functions of antibacterial, sterilization, and odor elimination.

[0022] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
