Description

Technical Field

[0001] The invention relates to the technical field of fiber preparation, in particular to a Shuku breathable fiber and a preparation method thereof. Background Art

[0002] Fiber refers to a substance composed of continuous or discontinuous filaments. In animals and plants, fiber plays an important role in maintaining tissues. Fiber has a wide range of uses. It can be woven into fine threads, threads and hemp ropes. It can also be woven into fiber layers when making paper or weaving felt. It is also often used to make other materials and to form composite materials with other materials. Natural fibers exist in nature and can be directly obtained. According to their sources, they are divided into three categories: plant fibers, animal fibers and mineral fibers.

[0003] As people's living standards continue to improve, their requirements for clothing are also increasing. Nowadays, people not only pay attention to the style of clothing, but also have higher and higher requirements for the functionality of clothing fabrics;

[0004] Especially in terms of health, in life, people are inevitably exposed to various bacteria, fungi and other microorganisms. These microorganisms spread diseases through contact and other means under suitable external conditions, thus affecting people's physical health and normal work, study and life. In addition, the air permeability of textile materials is also very important for human health. If the air permeability of textile materials is poor, it will cause the moisture on the skin surface to be unable to be removed in time, thus causing various diseases;

[0005] In order to achieve the antibacterial function, the current common practice is to use a finishing liquid with antibacterial function to impregnate the textile material so that the antibacterial components adhere to the surface of the textile material, thereby making the textile material antibacterial. However, such an approach will seriously affect the comfort of the textile material. The textile material will feel hard and the air permeability will be seriously reduced. In addition, the antibacterial components attached to the surface of the textile material have low fastness, are not resistant to washing, are easily lost, and have poor timeliness. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the present invention provides a Shuku breathable fiber and a preparation method thereof, which solves the problem that the existing textile materials have poor air permeability, resulting in the inability to remove moisture on the skin surface in time, thereby causing various diseases.

[0008] (II) Technical solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical scheme: a Shuku breathable fiber, the material composition and its mass fraction are: 50-100 parts of polymer, 0.3-0.7 parts of coupling agent, 2-6 parts of polyisophthalamide metaphenylene diamine condensation polymer, 1-4 parts of stain-resistant and antibacterial agent, 2-6 parts of titanium dioxide, 3-9 parts of aluminum carbide, 4-9 parts of rhubarb leaf extract, 3-6 parts of polyamide, 4-8 parts of yellowing resistance agent, 1.5-3.5 parts of anti-ultraviolet agent, 3-7 parts of surfactant, and 2-5 parts of strong hydrophilic group.

[0010] Preferably, the poly(m-phenylene isophthalamide) polycondensate is prepared by polycondensation of isophthaloyl chloride and m-phenylenediamine.

[0011] Preferably, the coupling agent is a silane coupling agent, a titanate coupling agent or a mixture thereof.

[0012] Preferably, the strong hydrophilic groups are carboxyl and hydroxyl groups.

[0014] S1. Pour the above raw materials into a stirring box and stir them evenly for 40-55 minutes, and then obtain a fiber-forming polymer through addition polymerization;

[0015] S2, placing the fiber-forming polymer in step S1 into a furnace and heating and melting it into a melt, with the temperature controlled at 1100-1400°C;

[0016] S3, pressing the melt in step S2 into a spinneret by a spinneret pump, and the melt flows out of the spinneret to form filaments;

[0017] S4, placing the melt filaments in a condensation medium for condensation, and the condensation time is controlled within 35-45 minutes;

[0018] S5. The filaments in step are post-treated by washing, desulfurization, bleaching, oiling and drying to obtain the Shuku breathable fiber body.

[0019] (III) Beneficial effects

[0020] The present invention provides a Shuku breathable fiber and a preparation method thereof, which has the following beneficial effects:

[0021] 1. The present invention uses polyisophthalamide-m-phenylenediamine condensation polymer as the main raw material, so that the produced Shuku fiber has high strength, friction resistance, corrosion resistance and excellent performance. At the same time, polyphenol compounds such as flaxenin, flaxenin and thiocyanate contained in the scutellaria baicalensis leaf extract are added to the raw material, which has antioxidant and antibacterial effects, improves the comfort of the entire fiber when used, and improves the flame retardant, moisture absorption and breathability, and antioxidant functions of the polyester fiber by adding titanium dioxide and aluminum carbide. The internal yellowing resistance agent, anti-ultraviolet agent and surfactant can improve the yellowing resistance and anti-ultraviolet function of the entire fiber, which is beneficial to its use.

[0022] 2. The present invention can improve the stain resistance of Shuku fiber by adding stain-resistant antibacterial agents into the raw materials, and can also improve its antibacterial value and stain level. The strong hydrophilic groups inside combine with water, and the flowing water rinses, thereby removing stains and improving its cleaning effect. DETAILED DESCRIPTION
