Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology, specifically to a production process for a functional fiber woven nonwoven fabric body. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is a new generation of environmentally friendly material, named for its resemblance to cloth and some of its properties. Nonwoven fabrics are mainly classified according to their production methods into spunlace nonwoven fabric, thermally bonded nonwoven fabric, wet-laid nonwoven fabric, spunbond nonwoven fabric, meltblown nonwoven fabric, and needle-punched nonwoven fabric. Existing fiber-woven nonwoven fabrics suffer from poor abrasion resistance, poor stain resistance and heat insulation, and low tensile strength, resulting in unsatisfactory overall performance. Furthermore, their poor washability and UV stability limit their usability. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the purpose of this invention is to provide a production process for functional fiber woven nonwoven fabric bodies to solve the problems mentioned in the background art.

[0004] The present invention solves the technical problem by adopting the following technical solution:

The nonwoven fabric body includes a nonwoven fabric substrate, an intermediate layer is provided on the upper and lower parts of the nonwoven fabric substrate, and an outer layer is provided on the outside of the intermediate layer.

[0006] The intermediate layer is bonded to the upper and lower parts of the nonwoven fabric substrate with polyurethane adhesive, and the amount of polyurethane adhesive used is 20g / m². 2 ;

[0007] The nonwoven fabric matrix is ​​woven from functional fibers, including first modified spandex fibers and polyester fibers. The first modified spandex fibers are used as warp threads and polyester fibers are used as weft threads. The warp and weft threads are woven together to form the nonwoven fabric matrix. The middle layer is formed by interweaving second modified polyester fibers and hemp fibers.

[0013] S1b: Nano-calcium carbonate, nano-bentonite, and β-cyclodextrin were mixed and compounded in a weight ratio of (2-3):(4-6):11. After mixing, the mixture was filtered and dried to obtain the modified nano-agent.

[0014] Preferably, the mass fraction of the ethanol-water solution is 75-80%; the stirring speed is 750-850 r / min, and the stirring time is 2 h.

[0015] Preferably, the method for preparing the first modified spandex fiber is as follows:

[0016] The spandex fiber was immersed in a sufficient amount of the first modification solution for immersion treatment. After immersion, it was dried at room temperature to obtain the first modified spandex fiber. The immersion power of the immersion treatment was 450-500W, the immersion time was 1h, and the immersion pressure was 10-15MPa.

[0017] The preparation method of the first modified liquid is as follows:

[0018] S21: Mix 5-8 parts of flake boron nitride, 3-5 parts of glass fiber, 5-8 parts of sodium carboxymethyl cellulose, 7-11 parts of sodium alginate solution, and 1-2 parts of nano silica sol thoroughly, then filter and dry to obtain flake boron nitride modifier.

[0019] S22: 4-7 parts of flake boron nitride modifier, 5-8 parts of 8% (w / w) dopamine hydrochloride solution and 1-2 parts of nano zinc oxide are mixed evenly to obtain flake boron nitride solution;

[0021] Preferably, the sodium lignosulfonate solution has a mass fraction of 10-15%; the sodium alginate solution has a mass fraction of 6-10%.

[0022] Preferably, the ultrasonic power of the blending ultrasonic treatment is 350-400W, and the ultrasonic treatment lasts for 1 hour.

[0023] Preferably, the method for preparing the second modified polyester fiber is as follows:

[0024] The polyester fiber was impregnated in a sufficient amount of the second modification solution. The impregnation power was 400-500W, the impregnation time was 1 hour, the impregnation pressure was 15MPa, and after the impregnation was completed, it was dried at room temperature to obtain the second modified polyester fiber.

[0025] Preferably, the second modified liquid comprises the following raw materials in parts by weight:

[0026] 3-5 parts glass microspheres, 2-5 parts lanthanum oxide, 4-6 parts chitosan solution, 1-2 parts magnesium aluminum spinel, and 2-4 parts zirconium silicate.

[0027] Preferably, the chitosan solution has a mass fraction of 2-5%.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The nonwoven fabric body of this invention is made of a nonwoven fabric matrix, an intermediate layer and an outer layer in combination. The nonwoven fabric matrix is ​​woven from a first modified spandex fiber and polyester fiber, the intermediate layer is woven from a second modified polyester fiber and hemp fiber, and the outer layer is formed by spraying an outer layer agent. Through the coordination between the layers, the product has excellent wear resistance, stain resistance, heat insulation and tensile strength, and the overall coordination effect of the product is significant. At the same time, the product has excellent water resistance and UV stability.

[0030] The first modified spandex fiber is treated by immersing the spandex fiber in a sufficient amount of the first modification solution. The first modification solution contains a compounding solution and a flake-shaped boron nitride solution, which are ultrasonically modified together. The flake-shaped boron nitride has a flake structure and excellent mechanical strength; its flake morphology can form a physical barrier on the fiber surface, improving the abrasion resistance and tear resistance of the spandex fiber. Simultaneously, the good chemical stability of boron nitride enhances the fiber's wash resistance and UV resistance. Glass fiber, as a rigid reinforcing phase, further enhances the fiber's breaking strength due to its high strength properties. Furthermore, the process involves re-blending sodium carboxymethyl cellulose, sodium alginate solution, and nano-silica sol raw materials. Through the synergistic coordination of these raw materials, the fiber's properties are further improved. The product's performance is further enhanced by the following steps: Ratosite, a layered clay mineral, has a lamellar structure that forms a barrier layer on the fiber surface, further enhancing the product's barrier properties and optimizing its insulation functions. Meanwhile, mullite whiskers, with their high-strength, high-modulus needle-like structure, form a "point-line-surface" multi-dimensional reinforcement system with lamellar boron nitride and glass fibers, further improving the product's performance. The intermediate layer of polyester fiber is impregnated in a second modification solution. The glass microspheres in the second modification solution harmonize with lanthanum oxide, magnesium aluminum spinel, and zirconium silicate raw materials. Through the synergistic effect of these raw materials, they work together to enhance the product's performance.

[0031] The curing agents, including polyurethane resin, bisphenol A epoxy resin, and m-phenylenediamine, as well as the blending and modifying nano-agents in the outer layer, optimize the product's performance through the co-coordination of raw materials. The modified nano-agents are composed of nano-calcium carbonate, nano-bentonite, and β-cyclodextrin solution. The β-cyclodextrin solution contains β-cyclodextrin, silane coupling agent KH560, and ethanol aqueous solution, which are mutually blended and optimized. Through the co-coordination and synergy of raw materials, β-cyclodextrin, with its amphiphilic structure, is compatible with both organic and inorganic materials. Combined with the silane coupling agent KH560, it acts as a bridge, connecting with nano-calcium carbonate and nano-bentonite on one hand, and with organic groups on the other, enhancing the connectivity of the raw materials. At the same time, nano-bentonite, with its layered silicate structure, acts as a barrier, while also coordinating with nano-calcium carbonate, optimizing the product's performance coordination, and improving the system's water resistance and UV stability.

[0153] As can be seen from Comparative Examples 1-10 and Example 3, the performance of the products tends to deteriorate when nano-calcium carbonate and nano-bentonite are not added in the preparation of the modified nano-agent, and β-cyclodextrin solution is not added in the preparation of the modified nano-agent. The performance of the product is most obvious when the modified nano-agent of the present invention is used.

[0154] The first modified spandex fiber was not prepared without the first modifying liquid, and the second modified polyester fiber was not prepared without the second modifying liquid. The performance of the products tended to deteriorate, especially under conditions of water washing resistance and UV resistance.

[0155] The first modified solution did not contain flake boron nitride solution, nor did it contain flake boron nitride or glass fiber. The first modified solution also did not contain a compounding solution, nor did it contain attapulgite or mullite whiskers. All of these resulted in varying degrees of performance degradation in the products. The first modified spandex fiber modified with the first modified solution obtained using the specific method of this invention exhibited the most significant performance improvement. Meanwhile, the second modified solution did not contain glass microspheres, lanthanum oxide, magnesium aluminum spinel, or zirconium silicate. All of these results in a deterioration in the product performance. Only the second modified solution prepared using the method of this invention showed the most significant performance improvement; other methods were not as effective as those of this invention.

[0156] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0157] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
