Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of flash spinning, in particular to a high-strength flash spun textile and a manufacturing method thereof.
[ background of the invention ]
The chemical fiber industry is an emerging industry that develops after new china is established. The chemical fiber is prepared by using natural high molecular compound or artificially synthesized high molecular compound as raw material and through the processes of preparing spinning solution, spinning, post-treatment and the like. The length, thickness, whiteness and gloss of the fiber can be adjusted in the production process. And respectively has the advantages of light resistance, wear resistance, easy washing, easy drying, no mildew and rot, no worm damage and the like. It is widely used for manufacturing clothing fabrics, filter cloth, conveyer belt, hose, rope, fishing net, electric insulating wire, medical suture, tyre cord fabric, parachute, etc. Chemical fibers are divided into two major classes, man-made fibers and synthetic fibers. In recent years, the chemical fiber yield of China is basically kept about 4000-5000 ten thousand tons, and the fluctuation range is not large. According to data, the chemical fiber yield in China in 2019 is 5952.8 ten thousand tons, which is increased by 534.8 ten thousand tons compared with the last year, and the yield is increased by 9.9 percent on the same scale. Therefore, china is a big country for the production of chemical fibers.
At present, through continuous technological attack for many years, chinese bio-based chemical fibers and raw material core technologies make new progress, the development of bio-based chemical fibers is mainly characterized by breaking through the manufacturing of key equipment for industrialization of bio-based chemical fibers, overcoming the technical bottleneck of industrialization of bio-based chemical fibers and raw materials, realizing the large-scale production of bio-based chemical fibers, and further expanding the application in the fields of clothing, home textiles and industrial textiles. The technical level and the industrialized development of the high-performance fiber in China also make great breakthrough, in the future, the key production and application technology of key varieties of the high-performance fiber is further promoted and broken through, the performance index stability of the fiber is further improved, and meanwhile, the application of the high-performance fiber in the fields of aerospace, ocean engineering, advanced rail transit, new energy automobiles, electric power and the like is expanded. In addition, with the improvement of living standard of people, new requirements are put forward on the characteristics of the clothes. The superfine fiber is an epoch-making product in the chemical fiber industry, and opens up a new era of textile products. Originally invented in the middle of the 60 s by doctor miyosi okamoto, the TORAY industrial textiles research laboratory. The superfine fiber is chemical fiber with extremely small filament number, and the standard of fine denier yarn in various countries in the world has no standard definition, but the fiber with the filament number smaller than 0.3dtex is a novel textile raw material with high quality and high technical content, and the product is light and thin in texture, soft and comfortable in hand feeling, good in drapability, large in specific surface area, strong in adsorption, excellent in warmth retention, waterproof and breathable performance and the like. The superfine fiber is a novel textile raw material with high quality and high technical content, and is widely applied to the aspects of clothing, home furnishing, decorative materials and the like. The preparation method of the superfine fiber comprises the following steps: a composite spin-stripping method, a dissolving method, an ultra-drawing method, a melt-blowing method, a flash evaporation method, and the like. Flash spun microfiber formation technology is one of the dry spinning processes, and the resulting fiber web has very fine fiber denier, typically 0.1 to 0.3dtex, originally discovered by the DuPont investigator White. At present, only two companies of DuPont and Asahi Kasei are known as flash-spun microfiber and nonwoven fabric production technologies, and the company is registered as TYVEK and ルクサ. No chemical fiber enterprises in China are put into the technical field of flash spinning for research, and although the chemical fiber yield is high, the chemical fiber enterprises in China are lack of research and development investment for top products in chemical fibers so as to overcome one of the technical difficulties of high-end chemical fibers. At present, the flash evaporation textile has the technical defects of high strength but poor printing performance due to the fact that polyethylene is used as a main raw material, and the purpose of the application is achieved mainly through improvement of flash evaporation raw materials and a process.
For the DuPont patented layout of flash technology, starting from the first flash technology patent in the last 60 s to the present, there was a cluster of 200 patents. We can also analyze the trend of flash evaporation technology from dupont. Most dupont patents are specific product properties that define the product, rather than the conventional raw materials or processes that define the product.

As a preferred technical scheme:
a manufacturing method of a multifunctional flash textile fabric comprises the following technical steps:
1. preparation of multifunctional polyvinyl acetate master batch
Dispersing the reduced graphene loaded with the nano-silver particles into a dilute sulfuric acid solution, adding a barium chloride solid, and filtering and drying to obtain the reduced graphene loaded with the nano-silver particles, the surface of which adsorbs barium sulfate; then adding zinc sulfide solid, mixing and grinding to obtain the nano silver particle-loaded reduced graphene doped with lithopone; then adding an aluminate coupling agent and polyvinyl acetate, and finally performing melt extrusion to obtain the multifunctional polyvinyl acetate master batch.
The mass ratio of the load nano silver particle reduced graphene to the barium chloride solid is 1:1-1:3;
the mass ratio of the barium chloride solid to the zinc sulfide solid is 1:1;
the mass fraction of the lithopone-doped nano-silver particle-loaded reduced graphene in the multifunctional polyvinyl acetate master batch is 8-10%.
The mass fraction of the aluminate coupling agent in the multifunctional polyvinyl acetate master batch is 1-2%.
Firstly, generating barium sulfate precipitates on the surface and in gaps of the reduced graphene loaded with the nano silver particles, then adding zinc sulfide solids, mixing and grinding to obtain lithopone adsorbed and wrapped on the reduced graphene loaded with the nano silver particles; has whitening and slow-release functions.
The lithopone is selected to mainly play a whitening function; and adding the loaded nano silver particles to reduce the graphene, wherein the nano silver has an antibacterial function, the flaky structure of the graphene has a function of serving as a carrier, and the loaded nano silver particles reduce the graphene into black powder. There is a contradiction that tests and analysis must select a proper interval between antibacterial property and whiteness, i.e. the whiteness of the textile is maintained under the premise of having better antibacterial effect.
The lithopone-doped nano silver particle-loaded reduced graphene serving as an inorganic material can be filled into fiber gaps of textiles in a flash spinning process, but the higher the addition amount is, the better the printability of the textiles is, but the higher the addition amount is, the flexible hand feeling and the air permeability of the textiles are reduced. A suitable interval between the feel of the textile and the printability needs to be sought.
The selected aluminate coupling agents herein start from: two active groups exist in the molecule of the aluminate coupling agent, and one RO group can react with the surface of the inorganic filler, namely can react with the inorganic powder; another type of COR group can be entangled with resin molecules, i.e., groups that interact with the polymeric binder. The aluminate coupling agent has a bridging function, one end of the aluminate coupling agent is connected with an inorganic substance, and the other end of the aluminate coupling agent is connected with polyvinyl acetate, so that the aluminate coupling agent has a better dispersing effect than the conventional silane coupling agent.
The polyvinyl acetate is selected as the matrix of the second polymer, mainly the structural characteristics of the polyvinyl acetate, and the polyvinyl acetate has good toughness, so that the technical problem of insufficient toughness of polyethylene raw materials can be solved.
The loaded nano silver particles of the present application reduce graphene, which has the basic properties: the sheet diameter is 500 nanometers to 5 micrometers, and the silver particle content is 50wt%.

The mass fraction of the mixture of the multifunctional polyvinyl acetate master batch and the polyethylene particles in the spinning solution is 12.6-14.6%.
The mass ratio of the polyethylene to the multifunctional polyvinyl acetate master batch is 1. When the content of the multifunctional polyvinyl acetate master batch is low, the toughening effect cannot be achieved; when the mass ratio is continuously increased, the improvement on the flexibility of the product is not obvious, but the production cost of the product is obviously increased (the price ratio of the polyethylene with the same mass to the multifunctional polyvinyl acetate master batch is 1:5), so the range of the mass ratio is selected by the application.
The spinning solvent is selected from one or more of aromatic hydrocarbons, aliphatic hydrocarbons, alicyclic hydrocarbons, unsaturated hydrocarbons, halogenated hydrocarbons, alcohols, esters, ethers, ketones, nitriles and fluorocarbon compounds.
The spin solvent is preferably 1,1-dichloro-2,2,2-trifluoroethane, 1,2-dichloroethylene, 1H-perfluorohexane, 2,3 dihydrodecafluoropentane, in a volume ratio of 4.
