Description
[ field of technology ]
The application relates to the technical field of flash spinning, in particular to a high-strength flash spinning textile and a manufacturing method thereof.
[ background Art ]
The chemical fiber is a fiber with spinning performance, which is prepared by using natural polymer compounds or artificially synthesized polymer compounds as raw materials and through the procedures of spinning dope preparation, spinning, post-treatment and the like. The length, thickness, whiteness, luster and other properties of the fiber can be adjusted in the production process. And has the advantages of light resistance, wear resistance, easy washing, easy drying, no mildew and rot, no worm damage, and the like. Is widely used for manufacturing clothing fabrics, filter cloth, conveyor belts, hose belts, ropes, fishing nets, electric insulation wires, medical sutures, tire cord fabrics, parachutes and the like. Chemical fibers are divided into two major classes, artificial fibers and synthetic fibers. In recent years, the chemical fiber yield of China is basically kept at about 4000-5000 ten thousand tons, and the fluctuation range is not large. According to the data, the chemical fiber yield of China in 2019 is 5952.8 ten thousand tons, which is increased by 534.8 ten thousand tons than in the last year by 9.9 percent. As can be seen, china is a large country of chemical fiber production.
At present, through the technological attack of continuous years, the Chinese bio-based chemical fiber and raw material core technology is newly developed, the development focus of the bio-based chemical fiber is to break through the manufacturing of bio-based chemical fiber industrialization key equipment, overcome the technical bottleneck of bio-based chemical fiber and raw material industrialization, realize the large-scale production of bio-based chemical fiber, and further expand the application in the fields of clothing, home textile and industrial textile. The technical level and the industrialization development of the high-performance fiber in China are also greatly broken through, key production and application technologies of key varieties of the high-performance fiber are further improved and broken through in the future, 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 the living standard of people, new requirements are put on the characteristics of taking textiles. Ultrafine fibers are an epoch-making product in the chemical fiber industry, opening up an epoch of textile products. The first was invented by Miyoshi okamoto doctor of TORAY Industrial textile research laboratory in the middle of 60 s. The superfine fiber is a chemical fiber with extremely fine denier per filament, and the standard of the fine denier per filament is defined in random mode in all countries, but the fiber with the denier per filament of less than 0.3dtex is generally a novel textile raw material with high quality and high technical content, and the product has the characteristics of light and thin texture, soft and comfortable hand feeling, good drapability, large specific surface area, strong adsorptivity, good warmth retention property, water resistance, air permeability and the like. The superfine fiber is a novel textile raw material with high quality and high technical content, and has wide application in the aspects of clothing, home furnishings, decorative materials and the like. The preparation method of the superfine fiber comprises the following steps: composite spinning stripping, dissolution, superstretching, melt blowing, flash evaporation, and the like. Flash spinning ultrafine fiber forming technology is one of dry spinning, and the fiber fineness of the obtained fiber web is extremely fine, generally 0.1-0.3 dtex, and is found by White of Dupont company researchers at the earliest. The current technology for producing flash spun superfine fiber and nonwoven fabric is only two companies, dupont and japan, registered under the trade names TYVEK and jel, respectively. The Chinese chemical fiber enterprises do not have research in the technical field of flash spinning, and although the Chinese chemical fiber enterprises are large in chemical fiber yield, research and development investment on tip products in chemical fibers is lacking, so that one of the technical difficulties of high-end chemical fibers is overcome. At present, the flash evaporation textile has the technical proposal of improvement made by the technical defects of high strength but poor printability due to the polyethylene as the main raw material, and the aim of the application is mainly realized by the improvement of the flash evaporation raw material and the technology.
For the dupont's patent layout for flash technology, from the first flash technology patent in the last 60 th century to now, approximately 200 patent clusters. We can also analyze the development trend of flash technology from dupont patents. Most of the Du Bangda patents define products for specific product properties rather than conventional definition of products by raw materials or processes.

As a preferable 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 nano silver particle-loaded reduced graphene in a dilute sulfuric acid solution, adding barium chloride solid, filtering and drying to obtain the nano silver particle-loaded reduced graphene with the barium sulfate adsorbed on the surface layer; then adding zinc sulfide solid, mixing and grinding to obtain lithopone-doped load nano silver particle reduced graphene; then adding aluminate coupling agent and polyvinyl acetate, and finally obtaining the multifunctional polyvinyl acetate master batch through melt extrusion.

Firstly, generating barium sulfate precipitate on the surface and in gaps of the nano silver particle-loaded reduced graphene, then adding zinc sulfide solid, mixing and grinding to obtain lithopone adsorbed and coated on the nano silver particle-loaded reduced graphene; plays a role in whitening and slow-releasing.
The lithopone is selected to play a main role in whitening; and adding nano silver particle-loaded reduced graphene, wherein the nano silver has an antibacterial function, and the flaky structure of the graphene serves as a carrier, but the nano silver particle-loaded reduced graphene is black powder. There is a contradiction that a suitable interval must be chosen between antimicrobial and whiteness through experimentation and analysis, i.e. the whiteness of the textile is maintained with a good antimicrobial 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 more beneficial to printability of the textiles, but the higher the addition amount is, the soft hand feeling and air permeability of the textiles are reduced. A suitable interval between textile feel and printability is therefore sought.

The aluminate coupling agent has bridging function, one end is connected with inorganic matters, and the other end is connected with polyvinyl acetate, so that the aluminate coupling agent has better dispersing effect than the conventional silane coupling agent.
The polyvinyl acetate is selected as the matrix of the second polymer, mainly has the structural characteristics of the polyvinyl acetate, has good toughness, and can improve the technical problem of insufficient toughness of the polyethylene raw material.

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 1:0.04-1:0.08. 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 soft performance of the product is not obviously improved, but the production cost of the product is obviously increased (the price ratio of polyethylene with the same mass to the multifunctional polyvinyl acetate master batch is 1:5), so the application selects the range of the mass ratio.
The spinning solvent is selected from one or more of aromatic hydrocarbon, aliphatic hydrocarbon, alicyclic hydrocarbon, unsaturated hydrocarbon, halogenated hydrocarbon, alcohol, ester, ether, ketone, nitrile and fluorocarbon.
The spinning solvent is preferably 1, 1-dichloro-2, 2-trifluoroethane, 1, 2-dichloroethylene, 1H-perfluorohexane and 2, 3-dihydrodecafluoropentane, and the volume ratio of the four is 4:4:1:1.
