Description

Technical Field

[0001] The invention relates to the technical field of fabrics and their production, in particular to a production process of clothing fabrics, and also to a novel anti-fouling and cold-proof clothing fabric produced by adopting the process. Background Art

[0002] There are many types of fabrics available, but as people's living standards improve, new types that can meet the needs of different groups of people need to be provided. People's requirements for clothing are not only about clothing style and workmanship, but more about clothing quality, which requires that clothing fabrics should keep up with the development of clothing forms. The characteristics of fabrics such as functionality, comfort, environmental protection, and health have become topics that people are paying more and more attention to.

[0003] Now referring to the invention patent with application number 201810662834.7, the cold-proof fabric disclosed therein is obtained by mixing wool fiber, cashmere fiber, polyvinyl chloride fiber, silk fiber, nylon fiber and cotton and linen fiber. A detailed analysis of the aforementioned patent shows that the patent adopts a method of stacking multiple fibers to achieve a thermal insulation effect of one plus one greater than two. However, the mixture of multiple fiber materials means that when sweating, the heat is not easy to dissipate, which can easily induce cold, which is not conducive to the cold protection needs of outdoor activities. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a new type of anti-fouling and cold-proof clothing fabric and its process to obtain cold-proof, anti-fouling and scratch-resistant fabric, so that clothing made of this fabric can be better used in harsh outdoor environments.

[0005] A manufacturing process of clothing fabrics, comprising the following steps:

[0006] S1: polyethylene glycol and polyvinyl pyrrolidone are mixed in proportion to obtain a spinning solution;

[0007] S2 electrospins the spinning solution to obtain a phase change fiber;

[0008] S3, spinning the phase change fiber and the blended fiber respectively to obtain yarn A and yarn B, taking yarn A, yarn B and thermal insulation filler and blending them on a loom to obtain fiber cloth for later use;

[0009] S4 prepares nano titanium dioxide, and the prepared nano titanium dioxide is deposited by vacuum evaporation to obtain a nano titanium dioxide microporous membrane;

[0010] S5 takes glass fibers and spins and interweaves them to form glass fiber cloth;

[0011] S6 heat-presses and compounds the fiber cloth, the nano-titanium dioxide microporous membrane and the glass fiber cloth to obtain a three-layer composite clothing fabric.

[0012] As a further improvement of the above scheme, polyethylene glycol and polyvinyl pyrrolidone are taken in proportion, polyvinyl pyrrolidone is first dissolved in DMAC solvent, and then polyethylene glycol is added and stirred to obtain spinning solution, the stirring speed is 400-600r / min, and the stirring temperature is 50-60°C. In the present invention, polyvinyl pyrrolidone is dissolved in DMAC solvent to form spinning solution, and polyvinyl pyrrolidone is dispersed in the mixture as a fiber matrix to ensure the formation of nanofibers. In the present invention, polyethylene glycol is added for modification, and polyethylene glycol is used as a phase change component, which has the characteristic of being able to undergo phase change within a temperature range of 5-30°C. The effect of temperature regulation is achieved by polyethylene glycol, specifically: when polyethylene glycol changes from solid to liquid, the molecular structure of polyethylene glycol changes, thereby absorbing heat to overcome the interaction force between molecules, and at this time, heat is stored; when polyethylene glycol changes from liquid to solid, the molecular structure of polyethylene glycol changes again, and the stored heat is released, thereby achieving the purpose of temperature regulation.

[0013] As a further improvement of the above scheme, the specific operation of electrostatic spinning of the spinning solution is as follows: the spinning solution is prepared and electrostatic spinning is performed on an electrostatic spinning machine, the spinning conditions are voltage 5-15KV, injection speed 3-4ml / h, injection distance 90-120mm, and the obtained fiber is washed, oiled and dried. In the present invention, the phase change fiber obtained after polyethylene glycol modification can absorb or release heat when the temperature changes, thereby maintaining a constant temperature. The clothing fabric containing the phase change fiber can automatically adjust the internal temperature according to the change of the external temperature, so as to maintain a comfortable body temperature even in a cold environment.

[0014] As a further improvement of the above scheme, the blended fiber includes rabbit hair fiber, silk fiber and polyester fiber, and the mass ratio of the rabbit hair fiber, silk fiber and polyester fiber is 1 to 5:1 to 3:1.

[0015] As a further improvement of the above solution, the proportion of the heat-insulating filler in the fiber cloth is 5% to 17%, and the heat-insulating filler is any one of expanded cotton, down and foam plastic. In the present invention, heat-insulating filler is added to enhance the cold resistance of the fabric.

[0016] As a further improvement of the above scheme, the method for preparing nano titanium dioxide is specifically performed as follows:

[0017] S41 tetrabutyl titanate and anhydrous ethanol are mixed and stirred to prepare solution A, deionized water and anhydrous ethanol are mixed and nitric acid is added dropwise to adjust the pH value to 3-4 to prepare solution B;

[0018] S42 adding solution A dropwise into solution B at room temperature while stirring, so that solution A and solution B are hydrolyzed and polycondensed to form a light yellow transparent sol;

[0019] S43: drying the sol in a drying oven at 80°C for 24h to form a gel, placing the gel in a high-temperature furnace and heating it to 500°C for heat treatment, and keeping the temperature for 2h to obtain nano titanium dioxide powder. The clothing fabric of the present invention is added with nano titanium dioxide, which can stimulate electron transition under ultraviolet light irradiation to form electron-hole pairs with strong redox ability, so that it can react with water molecules and oxygen molecules to generate hydroxyl radicals and superoxide anion radicals with strong oxidizing properties, thereby degrading organic pollutants on the fabric to keep the surface of the fabric clean, and the photocatalytic effect of nano titanium dioxide can cause photodegradation of organic matter, giving the fabric anti-fouling and self-cleaning properties, and also improving the ultraviolet protection performance of the fabric, so that it is more suitable for use in outdoor severe cold environments.

[0020] As a further improvement of the above scheme, the method for treating nano titanium dioxide powder by vacuum evaporation deposition is specifically operated as follows: disperse the nano titanium dioxide powder in a polyethylene aqueous solution, transfer it into a vacuum heating, heat and evaporate the mixed solution, and vaporize it in a substrate to obtain a nano titanium dioxide microporous membrane. The present invention prepares nano titanium dioxide into a microporous membrane by vacuum evaporation deposition, and introduces it into clothing fabrics by combining hot pressing technology, and uses it as a surface layer to play a self-cleaning role, thereby giving the clothing fabrics an anti-fouling effect.

[0021] As a further improvement of the above scheme, glass fiber cloth is laid between the fiber cloth and the nano-titanium dioxide microporous membrane to form a stacked cloth blank, and the stacked cloth blank is input into a hot press and hot-pressed for 15 to 30 seconds at a temperature of 110 to 120° C. to obtain a three-layer composite clothing fabric.

[0022] A novel anti-fouling and cold-proof clothing fabric comprises the following components by weight: 30-60 parts of blended fibers, 6-10 parts of thermal insulation fillers, 11-20 parts of polyethylene glycol, 15-30 parts of polyvinyl pyrrolidone, 10-18 parts of nano titanium dioxide and 8-14 parts of glass fibers.

[0023] As a further improvement of the above scheme, the clothing fabric has an inner layer, an intermediate layer and an outer layer, wherein the blended fiber, thermal insulation filler, polyethylene glycol and polyvinyl pyrrolidone are mixed in a ratio of 3-10:1:1-4:1.5-5 to make the inner layer, nano titanium dioxide is subjected to vacuum evaporation deposition to form the outer layer, and glass fiber is spun to form the intermediate layer. In the present invention, the added glass fiber has high strength, high modulus and good corrosion resistance. As a reinforcing layer, after being spun to form a glass fiber cloth, it is hot-pressed and compounded on the outermost side of the fabric, which enhances the wear and scratch resistance of the fabric and can be better applied to outdoor environments.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention introduces polyethylene glycol for modification. The phase change fiber obtained after polyethylene glycol modification can absorb or release heat when the temperature changes, thereby maintaining a constant temperature. The clothing fabric containing the phase change fiber can automatically adjust the internal temperature according to the change of the external temperature, thereby maintaining a comfortable body temperature even in a cold environment. In addition, nano titanium dioxide is added to give the fabric anti-fouling and self-cleaning properties, and also improves the ultraviolet protection performance of the fabric, so that it is more suitable for use in outdoor severe cold environments.

[0026] The production process of the present invention uses a spinning solution formed by mixing polyethylene glycol and polyvinyl pyrrolidone to perform electrostatic spinning to obtain phase change fibers, and a fiber cloth formed by interweaving thermal insulation fillers and blended fibers as an inner layer, a nanofilm formed by depositing nano titanium dioxide by vacuum evaporation as an intermediate layer, and a glass fiber cloth formed by spinning glass fibers as an outer layer. The three layers are hot-pressed and composited to obtain clothing fabrics. The clothing fabrics have the advantages of cold resistance, stain resistance and scratch resistance, and can be better suitable for use in harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS
