Description

Technical Field

[0001] The utility model relates to a cashmere viscose antibacterial yarn, belonging to the technical field of yarns. Background Art

[0002] As a natural animal protein fiber, cashmere fiber is an important raw material for the textile industry and an important fiber raw material for making high-grade fabrics. Cashmere products have a unique style of being comfortable to wear, having strong warmth retention, a plump pile surface, a soft handfeel, a soft luster, and being smooth and waxy, and are deeply favored by consumers. However, cashmere has disadvantages such as high raw material cost and insufficient fiber strength. Pure cashmere yarn clothing products are afraid of being washed, and are prone to pilling and deformation. Viscose fiber belongs to cellulose fiber. It uses natural fibers (wood fiber, cotton linter) as raw materials, and is made into soluble cellulose xanthate through processes such as alkalization, aging, and sulfonation, and then dissolved in dilute alkali solution to make viscose, and is made by wet spinning. It has good moisture absorption effect. However, both cashmere fiber and viscose fiber are short fibers, and the yarns prepared have deficiencies in terms of strength, and such yarns cannot be used to prepare fabrics required for anti-cutting and other aspects. How to prepare a cashmere viscose antibacterial yarn with high strength and anti-cutting becomes a problem to be solved. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cashmere viscose antibacterial yarn with high strength and anti-cutting effect.

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

[0005] A cashmere viscose antibacterial yarn involved in the utility model includes a core yarn, a first coating fiber layer, and a wrapping yarn layer; the core yarn includes ultra-high molecular weight polyethylene filaments and nylon monofilaments that are twisted together; the first coating fiber layer is a plant extract-modified viscose fiber; the wrapping yarn layer is an antibacterial cashmere fiber yarn.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the diameter of the nylon monofilament is 0.1 mm; the fineness of the ultra-high molecular weight polyethylene filament is 400 D.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: a second coating fiber layer is arranged between the core yarn and the first coating fiber layer; the second coating fiber layer is an aerogel fiber.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the wrapping yarn layer further includes a bamboo charcoal cashmere blended yarn, which is cross-wrapped around the outside of the first coating fiber layer in the opposite direction to the antibacterial cashmere fiber yarn.

[0009] Based on the above solution and as a preferred solution of the above solution: The plant extract modified viscose fiber is mugwort fiber or golden coptis fiber.

[0010] The beneficial effects of the present utility model are as follows: For the cashmere viscose antibacterial yarn involved in the present utility model, ultra-high molecular weight polyethylene filaments are used in the core yarn, which can effectively improve the strength and cut resistance of the yarn, and can also improve the dimensional stability of the prepared fabric. The antibacterial cashmere fiber yarn used on the outermost side can improve the hand feeling and wearing comfort of the fabric. Description of the Drawings

[0012] Figure 2 It is a schematic structural diagram of the cashmere viscose antibacterial yarn involved in the second embodiment.

[0013] The notations in the figure are explained as follows: 1 - core yarn; 2 - first covering fiber layer; 3 - wrapping yarn layer; 4 - second covering fiber layer Detailed Embodiments

[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 , a detailed description of this embodiment is given. A cashmere viscose antibacterial yarn involved in this embodiment includes a core yarn 1, a first covering fiber layer 2 and a wrapping yarn layer 3; the core yarn 1 includes ultra-high molecular weight polyethylene filaments and nylon monofilaments twisted together, the first covering fiber layer 2 is a plant extract modified viscose fiber; the wrapping yarn layer 3 is an antibacterial cashmere fiber yarn.

[0017] Further, the plant extract-modified viscose fiber is wormwood fiber or golden coptis fiber. The plant extract-modified viscose fiber is prepared by dissolving the plant extracts of several antiviral plants into distilled water respectively. The mixing ratio of the plant extract to the distilled water is between 1:5, and the dissolution temperature is between 40°C and 60°C. After sufficient dissolution, several plant extract mixtures are obtained. The several plant extract mixtures are mixed in a ratio of 1:1 to prepare an antibacterial mixture, and then the antibacterial mixture is mixed with the viscose spinning solution in a ratio of 1:7 to prepare a viscose spinning mixture. Then, the viscose spinning mixture is stirred until uniform, left standing for defoaming and then filtered; by wet spinning, the viscose spinning mixture is extruded through a spinneret into a coagulation bath. In terms of mass percentage concentration, the sulfuric acid concentration in the coagulation bath is 80 g / L, the sodium sulfate concentration is 250 g / L, the zinc sulfate concentration is 5 g / L, the coagulation bath temperature is 60°C. After the viscose spinning mixture solidifies into a fibrous shape, it is taken out and post-treated to obtain the plant extract-modified viscose fiber. The plant extracts mainly include the plant extracts of wormwood, honeysuckle, coptis and forsythia, etc., and have good antibacterial effects.

[0018] Further, the diameter of the polyamide monofilament is 0.1 mm; the fineness of the ultra-high molecular weight polyethylene filament is 400 D.
