Description

Technical Field

[0001] This utility model relates to a yarn, specifically a heat-insulating and antibacterial acrylic yarn. Background Art

[0002] Acrylic fiber is a synthetic fiber, chemically known as polyacrylonitrile fiber. It possesses many excellent properties, such as crispness, wrinkle resistance, and warmth retention. The warmth retention of acrylic fiber primarily stems from its internal structure. Acrylic fibers contain numerous tiny pores that trap air. Air is an excellent thermal insulator, allowing fabrics made from acrylic yarn to effectively prevent heat transfer and thus provide insulation. In daily life, fabrics easily harbor various bacteria, molds, and fungi. The growth of these microorganisms not only produces unpleasant odors but can also harm human health, causing problems such as skin allergies and infections. Due to its inherent chemical structure, acrylic yarn also easily becomes a breeding ground for microorganisms, especially in humid environments or when the body sweats excessively. The surface humidity and temperature of fabrics woven from acrylic yarn are ideal for microbial growth and reproduction. Therefore, it is necessary to provide a heat-insulating and antibacterial acrylic yarn. Utility Model Content

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Combination Figure 1 This embodiment provides a detailed description of a heat-insulating and antibacterial acrylic yarn, comprising: a yarn body, the yarn body including a first yarn 1 and a second yarn 2; the first yarn 1 is spirally wound around the outside of the second yarn 2; the first yarn 1 is formed by twisting acrylic fiber yarn 3 and antibacterial fiber yarn 4 together; the second yarn 2 includes a core yarn 5 and an outer covering fiber 6; the outer covering fiber 6 is twisted and wrapped around the outside of the core yarn 5; the core yarn 5 is an elastic fiber filament; the outer covering fiber 6 is a warm ginger fiber.

[0014] Warm ginger fiber originates from the herbaceous plant ginger. The active ingredients are extracted from fresh ginger, concentrated, and dried to create ginger extract, which is then ground into nano-sized powder. This powder is then blended with natural wood pulp to obtain the final product. This fiber possesses natural antibacterial properties, exhibiting strong inhibitory effects against common bacteria such as Staphylococcus aureus, Escherichia coli, and Candida albicans. It also provides warmth, moisture absorption and heat generation, and heat retention.

[0015] Furthermore, the acrylic fiber used in the acrylic fiber yarn 3 is an antibacterial modified acrylic fiber. In this embodiment, the antibacterial modified acrylic fiber is a wet-spun acrylic fiber. When ordinary acrylic fiber dosing is mixed with solvent, hydrophilic cellulose acetate dosing is added, and after uniform mixing, chitosan ultrafine powder is added and blended to form a spinning dosing, which is then wet-spun into fibers. This antibacterial modified acrylic fiber has many micropores on its surface. When moisture passes through the micropores, it is absorbed by acetic acid, and the water vapor releases heat due to condensation and liquefaction, thereby generating moisture absorption and heat generation efficiency. The chitosan used in the blend is treated with concentrated alkali to remove acetyl groups and become soluble chitosan. The chitosan seeps out through the micropores on the acrylic fiber surface and can be adsorbed onto the negatively charged bacterial cell walls, forming a polymer membrane on the cell membrane surface. This prevents the exchange of nutrients between the inside and outside of the tissue cells and the normal metabolism of the cells, thus playing a bactericidal role.

[0016] Furthermore, the antibacterial fiber yarn 4 is a gingerol viscose fiber yarn. Gingerol viscose fiber is produced by encapsulating gingerol with β-cyclodextrin to form microcapsules, then adding the microcapsules to the viscose spinning solution, and finally producing the yarn through pre-spinning blending and wet spinning processes. The gingerol viscose fiber exhibits antibacterial rates of 92.0%, 91.0%, and 82.0% against Staphylococcus aureus, Escherichia coli, and Candida albicans, respectively, demonstrating excellent antibacterial effects. Compared to regular viscose fiber, gingerol viscose fiber has an increased number of grooves on its surface, enhancing its moisture absorption capacity. The presence of β-cyclodextrin encapsulating gingerol in the fiber, along with its higher water content than cellulose, further enhances its moisture absorption capacity. This increased moisture absorption capacity improves the yarn's moisture absorption and heat dissipation properties, resulting in excellent heat retention.

[0017] Furthermore, the elastic fiber filament is an antibacterial PTT fiber filament. The antibacterial PTT fiber filament is prepared by a masterbatch addition method, which involves blending silver-based antibacterial masterbatch and PTT chips through melt spinning. It possesses the excellent resilience of PTT fibers, enhancing the elasticity of the yarn body. The silver-based antibacterial agent has a good antibacterial effect against a broad spectrum of microorganisms. When bacteria and viruses come into contact with the fiber surface, the active ingredient Ag+ in the antibacterial agent can penetrate the negatively charged bacterial cell wall and rapidly bind to the sulfhydryl groups and amino groups on the enzyme proteins within the bacteria, disrupting the normal structure of proteins and nucleic acids, causing microbial death or loss of reproductive ability, thereby achieving antibacterial and bactericidal effects. Therefore, the antibacterial PTT fiber filament also has a good antibacterial effect.

[0018] Example 2

[0019] The difference from Example 1 is that the antibacterial fiber yarn 4 is an antibacterial and deodorizing viscose fiber yarn. The antibacterial and deodorizing viscose fiber is prepared by wet spinning, in which Isatis root extract and diatomaceous earth extract are added to the viscose spinning solution in a certain proportion using a blending spinning method. The Isatis root extract in the antibacterial and deodorizing viscose fiber shows good inhibitory effects against Staphylococcus aureus, Escherichia coli, Candida albicans, and Klebsiella pneumoniae, hindering bacterial growth and significantly reducing the odor components produced by bacteria decomposing human secretions, thus indirectly deodorizing. Diatomaceous earth can directly adsorb odor components, achieving optimal deodorization.
