Description

Technical Field

[0001] The invention relates to the technical field of fabric preparation, and in particular to a high-elastic non-woven composite fabric and a preparation method thereof. Background Art

[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing. Among them, functional fabric refers to fabric with certain special properties and uses, such as waterproof, windproof, breathable, moisture permeable, warm, oil-proof, easy to clean, anti-bacteria and deodorizing, UV protection, anti-static, radiation protection, flame retardant, high temperature resistance, acid and alkali resistance, etc. The functional fabrics on the market are mainly clothing fabrics, mostly used in outdoor sportswear and high-end casual wear.

[0003] The elastic effect of fabrics mainly depends on the characteristics of the fibers used in the fabrics. If the elasticity of the fibers is good, the elasticity of the fabrics will also be good, otherwise the elastic effect of the fabrics will be poor. Currently, the most commonly used elastic fiber on the market is polyurethane fiber. The existing fabrics can increase various materials such as flexibility, comfort and warmth when used. However, based on the fabrics, there are still some shortcomings in the actual use process. For example, the fabrics may have curling problems during use, or the anti-static and elastic effects are not very good.

[0004] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "high-elastic antibacterial fabric and its preparation method", and its application number is "202311352823.6". The patent mainly adopts that the fabric is obtained by blending modified polyurethane fiber and polyester fiber. The modified polyurethane fiber has higher elasticity and strength than traditional polyurethane fiber, and also has good antibacterial and heat resistance. The fabric prepared after blending with polyester fiber also has high strength, high elasticity, good antibacterial and heat resistance; the antibacterial effect is achieved, but there are still shortcomings based on the use of the fabric. Therefore, according to the applicant's invention, a preparation method of a high-elastic non-woven composite fabric was invented to solve the problems of poor antistatic and elastic effects. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a high-elastic non-woven composite fabric and a preparation method thereof, which solves the problems of poor antistatic and elastic effects.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical scheme: A method for preparing a high-elastic non-woven composite fabric, comprising the following specific steps:

[0009] Step 1: Prepare fabric spinning liquid

[0010] Stir 40-60 parts of natural fiber, 15-25 parts of viscose fiber, 5-10 parts of polylactic acid, 10-15 parts of spandex fiber and 10-15 parts of conductive fiber cloth according to mass proportion until they are uniformly dissolved; then add 2-8 parts of photoinitiator and stir to react;

[0011] Step 2: Fabric spinneret preparation

[0012] The uniformly dissolved textile liquid is transported to the spinning equipment through a metering pump for spinning operation. The spinning flow channel needs to be heated in advance. The spinning liquid is sprayed out through the spray holes in the spinneret and passes through the preheated air channel. The solvent in the spinning liquid is heated to a dry state, and the formed filaments can be recovered on the surface of the winding roller to complete the winding, which is convenient for subsequent textile use;

[0013] Step 3: Fabric and textile yarn preparation

[0014] The rolled textile fiber fabric is circulated through a conveying roller and then sent into a large circular textile machine for weaving to obtain a highly elastic anti-curling fabric;

[0015] Step 4: Add the color dye to 100 mL of deionized water, stir for 30 minutes, then immerse the high-elastic non-woven fabric in the dye, stir at a uniform speed to form a 1mm-2mm nano-pigment coating, and dry it in an oven to obtain the wear-resistant high-elastic composite fabric.

[0016] Preferably, the stirring and dissolving time in step 1 is 1-1.5 hours at 60-80° C., and the stirring reaction time in step 1 is 0.5-1 hour.

[0017] Preferably, the diameter of the spinneret hole of the spinneret in step 2 is 0.01-0.12 mm.

[0018] Preferably, the natural fiber in step one can be divided into: a mixture of any one or more of cotton fiber or hemp fiber.

[0019] Preferably, the conductive fiber cloth in step one is made of carbon fiber, so that the cloth has conductive properties.

[0020] Preferably, the weaving in step three is cross weaving.

[0021] Preferably, the oven temperature in step 4 is 80° C., and the drying is carried out in the oven for 2 hours.

[0022] A high-elastic non-woven composite fabric is prepared by a method for preparing a high-elastic non-woven composite fabric.

[0023] (III) Beneficial effects

[0024] The present invention provides a high-elastic non-woven composite fabric and a preparation method thereof. It has the following beneficial effects:

[0025] 1. The present invention is provided with polylactic acid. By adding polylactic acid in the fabric preparation process, the fabric has good hygroscopicity, air permeability, wear resistance, and soft hand feel. In actual use, the curling problem of the existing fabric mentioned in the background technology can be effectively solved, which affects the use effect of the fabric. Thus, polylactic acid provides environmentally friendly degradation, non-toxic anti-mite, antibacterial health care, fire and moisture resistance.

[0026] 2. The present invention is provided with: conductive fiber cloth, the conductive fiber cloth adopts carbon fiber, so that the cloth has conductive properties, thereby effectively preventing the generation of static electricity. This cloth can effectively conduct away the static electricity generated on the surface of the fabric, thereby achieving the purpose of anti-static.

[0027] 3. The present invention is provided with spandex fiber. The high elasticity effect of the cloth in the prior art is derived from the fact that the modified polyurethane fiber has higher elasticity and strength than the traditional polyurethane fiber. The advantages of adding spandex fiber in the present invention include high elasticity, durability, breathability, non-wrinkling, easy care, lightness and softness, and good dyeability. The addition of spandex fiber brings many advantages to the cloth, the most notable of which is its high elasticity, which can be stretched to 4-7 times of its original length, thereby providing better fit and comfort, and can achieve high elasticity and good dyeability, and is more suitable for use in cloth.
