Description

Technical Field

[0001] The invention belongs to the technical field of fabrics and relates to a breathable and comfortable fabric and a preparation method thereof. Background Art

[0002] One of the main areas of utilization of petroleum resources is synthetic fibers. However, since chemical fiber production is accompanied by a large amount of discharge, some of the raw materials, by-products and a small amount of residues will cause serious pollution to the environment. Natural plant fiber is a natural polymer material taken from the stems and leaves of green plants. It is degraded and fermented by chemical or biological methods to finally obtain clean and renewable energy such as ethanol. Natural fiber is a renewable and environmentally friendly resource that conforms to the national green environmental protection and sustainable development strategy.

[0003] The plant kudzu consists of three parts: kudzu leaves, kudzu roots and kudzu vines, all of which are rich in fiber. The bast fiber in the kudzu vine is ivory white, soft and slender, and is mainly used in the textile field. The kudzu fiber aggregate produces a large amount of hairiness during the twisting process, which increases the friction on the fiber surface, protects the fiber body itself and increases the wear resistance of the fiber. Kudzu fiber has strong moisture absorption and air permeability, can be quickly wetted when it encounters water, and has a fast moisture conduction rate. However, the deformation ability of kudzu fiber monomers is poor, and the textiles are stiff and not smooth. At the same time, the wrinkle resistance is poor, and the changeability is not easy to recover.

[0004] Palm is the most widely distributed and highest latitude palm species in China. The palm bark fiber is mainly used to make ropes, straw raincoats, palm mats, carpets, brushes and sofa fillings. Palm fiber has low density, good elasticity, corrosion resistance, high water absorption, abundant sources and low prices. It is an excellent natural plant fiber. Summary of the invention

[0005] The present invention relates to a breathable and comfortable fabric and a preparation method, and belongs to the technical field of fabrics. The present invention discloses a breathable and comfortable fabric comprising the following raw materials in parts by weight: 30 to 50 parts of natural mixed fibers, 30 to 50 parts of polyester fibers, 5 to 10 parts of spandex fibers, 10 to 20 parts of natural dyes, 5 to 10 parts of water-based polyurethane glue, 5 to 8 parts of moisturizers, and 2 to 3 parts of dispersants. The present invention prepares textile fabrics through natural mixed fibers, so that the fabrics have antibacterial properties, skin-friendliness, moisture absorption and air permeability, and at the same time enhance the elasticity and wear resistance of the fabrics. The TPU nanofiber membrane is compounded with the fiber to enhance the color fixing effect of the dye, and at the same time form a uniform nanofiber mesh structure with good air permeability. The components cooperate with each other to prepare a breathable and comfortable textile fabric.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A breathable and comfortable fabric comprises the following raw materials in parts by weight: 30-50 parts of natural mixed fiber, 30-50 parts of polyester fiber, 5-10 parts of spandex fiber, 10-20 parts of natural dye, 5-10 parts of water-based polyurethane glue, 5-8 parts of moisturizing agent and 2-3 parts of dispersant.

[0008] Furthermore, the method for preparing the natural mixed fiber comprises the following steps:

[0009] (1) Mix kudzu vine and palm bark, add water and heat;

[0010] (2) cooling the mixture, adding a fermentation agent for fermentation, adding alkali treatment, washing with water, and removing the kudzu core to obtain the natural mixed fiber.

[0011] Furthermore, in the step (1), the mass ratio of kudzu vine to palm bark is 1:1, the heating refers to heating to 80-100° C., and the heating time is 2-3 hours.

[0012] Furthermore, the cooling in step (2) refers to cooling to 28-30° C., the fermentation agent is Trichoderma, the fermentation time is 2-3 days, and the alkali in step (2) is sodium hydroxide or ammonia water.

[0013] Furthermore, the preparation method of the natural dye comprises the following steps:

[0014] The plant raw materials are crushed, ethanol is added for soaking, and then filtered, and the filtrate is dried to obtain a natural dye.

[0015] Furthermore, the plant raw material is any one of Phellodendron amurense, mangrove, Lithospermum officinale, chestnut shell, woad, mustard and clove.

[0016] Furthermore, the moisturizing agent is composed of glycerin and amino silicone oil, and the mass ratio of the two is 1:1, and the dispersant is polyvinyl alcohol or carboxylate.

[0017] The preparation method of the above-mentioned breathable and comfortable fabric comprises the following steps:

[0018] S1: blending natural mixed fiber, polyester fiber and spandex fiber, and then heating and adding natural dye and dispersant for dyeing;

[0019] S2: Then, water-based polyurethane glue is sprayed on the surface to cause a curing reaction, and a moisturizer is added to prepare a breathable and comfortable fabric.

[0021] Furthermore, the breathable and comfortable fabric is applied to underwear, wedding dresses and webbing products.

[0022] Beneficial effects of the present invention:

[0023] (1) The kudzu fiber and palm fiber in the natural blended fiber complement each other, and the prepared fabric has antibacterial, skin-friendly, moisture-absorbing and breathable properties, while enhancing the elasticity and wear resistance of the fabric. Natural plant fiber is a natural polymer material that can be degraded and fermented by chemical or biological methods to ultimately produce clean and renewable energy such as ethanol, greatly reducing environmental pollution.

[0024] (2) By adding glycerol and amino silicone oil as moisturizers, the two can work together to achieve a better moisturizing effect.

Therefore, the softness and comfort of the fabric are improved.

[0025] (3) The TPU nanofiber membrane is composited with the fiber, which enhances the color fixation effect of the dye and forms a uniform nanofiber network structure with good air permeability. DETAILED DESCRIPTION

[0090] Comparative Example 4

[0091] On the basis of Example 2, the glycerin in the raw material composition and preparation process of the breathable and comfortable fabric is removed and replaced with an equal mass of amino silicone oil. Other conditions are consistent with Example 2.

[0096] 1. Wear resistance test

[0097] Abrasion resistance fastness test: Y571B friction color fastness tester (Wenzhou Fangyuan Instrument Co., Ltd.) was selected, and standard wool abrasive was used. The fabric samples made in Examples 1 to 3 and Comparative Examples 1 to 2 were placed on the circular friction head (flat grinding) of the sponge cushion layer and rubbed 500 times. Combined with image processing technology, the wear area of ​​the sample before and after the test was used to characterize the abrasion resistance fastness. Each sample was tested 5 times, and the results were averaged. In order to simulate the abrasion resistance fastness of the sample under different environments, hydrochloric acid, calcium hydroxide and sodium chloride solutions with a mass fraction of 20% were prepared respectively. After the samples were immersed in these three solutions for 24 hours, the abrasion resistance fastness test was carried out, and the test method was the same as above. The test results of Examples 1 to 3 and Comparative Examples 1 to 2 are shown in Table 1.

[0098] Table 1 Wear resistance test results

[0099]

[0100]

[0101] From the data analysis in Table 1, it can be concluded that the fabric area loss of Examples 1 to 3 is less than that of Comparative Example 1 but greater than that of Comparative Example 2. Because the kudzu fiber aggregate produces a large amount of hairiness during the twisting process, the hairiness increases the friction on the fiber surface, protects the fiber body itself and increases the wear resistance of the fiber. By comparing the three solutions, it is found that the area loss rate of the two groups of samples with hydrochloric acid and sodium hydroxide is greater than that of the sample with sodium chloride. Among them, the area loss rate of the fabric added by the three solutions in Comparative Example 1 is slightly different, while that in Comparative Example 2 is significantly different. Palm fiber is a natural plant fiber with corrosion resistance.

[0102] 2. Test of air permeability and color fastness

[0103] Air permeability: The fabrics obtained in Examples 1 to 3 and Comparative Example 3 were made into specimens, and the air permeability of the film and the amount of air passing through the film of a specified area were measured using an RT-5300 textile air permeability tester according to ASTM D 737-2018 “Standard Test Method for Air Permeability of Textile Fabrics”.

[0104] Color fastness: The fabrics obtained in Examples 1 to 3 and Comparative Example 3 were made into samples and tested according to GB / T5713-1997 "Textiles - Tests for Color Fastness - Water Fastness". The test results of air permeability and color fastness are shown in Table 2.

[0105] Table 2 Air permeability test results

[0106] Sample <![CDATA[Air permeability (mm·s -1 )]]> Water color fastness / grade Example 1 9.28 4 Example 2 9.30 4 Example 3 9.37 4 Comparative Example 3 9.52 2-3

[0107] It can be seen from Table 2 that the air permeability of Examples 1 to 3 and Comparative Example 3 is very similar, while the water fastness of Examples 1 to 3 is level 4, which is greater than that of Comparative Example 3. The TPU nanofiber membrane is compounded with the fiber to enhance the color fixation effect of the dye, while forming a uniform nanofiber network structure with good air permeability.

[0108] 3. Compression performance test

[0109] Sample preparation: The fabrics prepared in Examples 1 to 3 and Comparative Examples 4 to 6 were stacked into cubes with a thickness of 100 mm and a density of 600 g·m -2 The test was conducted using a YG141N digital fabric thickness tester in accordance with GB / T 3820-1997 "Textiles and Textile Thickness Determination". The compression performance of the fiber is evaluated by the relationship between the fiber thickness and the applied pressure. The greater the thickness change of the sample with increasing pressure, the better its compression performance. The test results are shown in Table 3.

[0110] Table 3 Compression performance test results

[0111]

[0112] As can be seen from Table 3, the thickness of the five samples of Examples 1 to 3 and Comparative Examples 4 to 6 gradually decreases with the increase of pressure, and the rate of change gradually decreases. Among them, the thickness change of the samples of Examples 1 to 3 is more obvious than that of the samples of Comparative Examples 4 to 6, indicating that the compression performance of the samples of Examples 1 to 3 is better, and therefore the softness is better. By adding glycerol and amino silicone oil as moisturizers, the two can work together to achieve a better moisturizing effect. Glycerol can provide a short-term moisturizing effect, while amino silicone oil can provide a more lasting moisturizing effect. Alkali treatment can weaken and degrade the internal skeleton structure of cellulose fibers, reduce the cross-linking and mutual restraint between fibers. Therefore, the softness of the fabric is improved.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
