Description

Technical Field

[0001] The invention relates to the technical field of antifouling fabrics, in particular to an antifouling fabric and a preparation process 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. In the world of clothing, clothing fabrics are varied and changing with each passing day. But generally speaking, high-quality and high-end fabrics are mostly comfortable to wear, sweat-absorbent and breathable, drape straight, visually noble, and soft to the touch.

[0003] The main principle of anti-fouling fabrics is to reduce the surface tension of the fabric so that it has the ability to resist water wetting and oil liquids. Specifically, anti-fouling fabrics use specific "three-proof" additives, such as fluorinated polyacrylate functional finishing agents or organic fluorine-silicon copolymer finishing agents. The fluorine atoms in these additives have large electronegativity and small diameter, which can significantly reduce the surface free energy of the compound, thereby giving the fabric a lower surface tension. In addition, the water-resistant principle of the lotus leaf surface is also applied to certain "three-proof" finishing agents. Through nanotechnology, a layer of polyfluorosilane with a micro-nano bionic raised structure is formed on the surface of the clothes, similar to the surface structure of the lotus leaf. This structure can form a certain isolation layer on the fabric, so that water and oil stains can slide down in a certain direction when they are stained on the clothes, thereby achieving the effect of waterproofing and oil stains.

[0004] At present, when preparing antifouling fabrics, the yarns of the antifouling fabrics are usually treated to obtain antifouling yarns, so that the antifouling fabrics can be woven based on the yarns later. However, after the antifouling fabrics treated in this way are woven, nano-components are prone to remain, which will fall off later and cause waste of raw materials. Summary of the invention

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] Example 1, please refer to Figures 1-4 , the present invention provides a technical solution: an anti-fouling fabric, characterized in that the anti-fouling fabric comprises the following components: warp yarns, weft yarns; Among them, the warp yarns and weft yarns are knitted to form a fabric matrix, the warp yarns and weft yarns are the same, and the warp yarns and weft yarns are both composed of plant fibers, carbon fibers, and polyurethane elastic fibers; the fabric matrix is surface-treated with a nano-scale fluorinated polyacrylate functional finishing agent or an organofluorosilicon copolymer finishing agent to obtain an anti-fouling fabric.

[0023] Analysis of the above content: The warp yarns and weft yarns are made of plant fibers, carbon fibers, and polyurethane elastic fibers in equal proportions. Based on the knitting treatment of the warp yarns and weft yarns, a fabric matrix is obtained. At this time, the fabric matrix does not yet have the function of anti-fouling. Then, based on the nano-scale fluorinated polyacrylate functional finishing agent or the organofluorosilicon copolymer finishing agent, the surface of the fabric matrix is modified to obtain an anti-fouling fabric.

[0024] Nano-scale fluorinated polyacrylate functional finishing agent: Structure and composition: Using polyacrylate as the backbone, fluorinated groups are introduced into the molecular structure through chemical bonding and other methods. Fluorinated groups usually have a low surface energy, which can endow the finishing agent with excellent water and oil repellent properties. The nano-scale particle size enables the finishing agent to better penetrate into the fabric fibers and improve the durability of the finishing effect.

[0025] Performance characteristics Excellent water and oil repellent properties: The presence of fluorinated groups forms a low surface energy protective film on the fabric surface, which can effectively prevent the penetration of liquids such as water and oil, making the fabric have good waterproof and oil-proof effects.

[0026] Good air permeability: The protective film formed by the nano-scale finishing agent on the fabric surface has a certain porosity, which will not affect the air permeability of the fabric and maintain the comfort of wearing the fabric.

[0027] Good washability: It has a strong binding force with fabric fibers and can still maintain good water and oil repellent properties after multiple washes.

[0028] Organofluorosilicon copolymer finishing agent: Structure and composition: It is a copolymer formed by copolymerization of organofluoro groups and organosilicon groups. Organofluoro groups endow the finishing agent with water and oil repellent properties, while organosilicon groups have good softness and smoothness, which can improve the hand feeling of the fabric.

[0029] Performance characteristics Excellent comprehensive performance: It combines the water and oil repellency of fluorides and the soft and smooth characteristics of silicone, enabling the fabric to not only have good waterproof and oil-proof effects but also obtain a soft and comfortable handfeel.

[0030] Good weather resistance: It has good performance in resisting ultraviolet rays, oxidation, etc., and can maintain stable performance under long-term use and different environmental conditions.

[0031] Antibacterial property: Some organofluorosilicone copolymer finishing agents also have certain antibacterial properties, which can inhibit the growth and reproduction of bacteria on the fabric surface and improve the hygiene performance of the fabric.

[0032] Example 2, please refer to Figures 1-4 , based on Example 1, the present invention provides a technical solution: The mass ratios of the plant fiber, carbon fiber, and polyurethane elastic fiber to the warp yarn are: 20 parts - 40 parts of plant fiber, 15 parts - 35 parts of carbon fiber, and 25 parts - 65 parts of polyurethane elastic fiber.

[0033] Example 3, please refer to Figures 1-4 , based on Example 2, the present invention provides a technical solution: The mass ratios of the plant fiber, carbon fiber, and polyurethane elastic fiber can be any of the following three cases: The first case: The mass ratios of the plant fiber, carbon fiber, and polyurethane elastic fiber to the warp yarn are: 25 parts of plant fiber, 25 parts of carbon fiber, and 50 parts of polyurethane elastic fiber.

[0034] The second case: The mass ratios of the plant fiber, carbon fiber, and polyurethane elastic fiber to the warp yarn are: 30 parts of plant fiber, 20 parts of carbon fiber, and 50 parts of polyurethane elastic fiber.

[0035] The third case: The mass ratios of the plant fiber, carbon fiber, and polyurethane elastic fiber to the warp yarn are: 35 parts of plant fiber, 25 parts of carbon fiber, and 40 parts of polyurethane elastic fiber.

[0036] Example 4, please refer to Figures 1-4 , the present invention provides a technical solution: A preparation process for a stain-resistant fabric, characterized in that the specific preparation steps of the preparation process for the stain-resistant fabric are as follows: Set a preparation box body 1 that is hollow and open at the upper part. Set a top cover 2 at the upper opening of the preparation box body 1, and set a support bar 11 for carrying the fabric substrate in the preparation box body 1; S1: Regulate the flow rate of the nano-scale fluorinated polyacrylate functional finishing agent or the organofluorosilicone copolymer finishing agent input into the preparation box body 1; S2: Lay the fabric substrate on the support bar 11 in the above-mentioned preparation box body 1 and finish the fabric substrate to make it flat; S3: A storage box 3 for storing nano-scale fluorinated polyacrylate functional finishing agent or organic fluorinated silicon copolymer finishing agent is set on the upper part of the preparation box 1. The storage box 3 is connected to the inner cavity of the preparation box 1 through a pipeline. An interface 4 for blowing high-pressure air into the preparation box 1 is set on the side wall of the preparation box 1. The position of the interface 4 corresponds to the position of the outlet of the pipeline at the lower part of the storage box 3. High-pressure air is blown into the preparation box 1 through the interface 4. Under the blowing of the high-pressure air, the nano-scale fluorinated polyacrylate functional finishing agent or organic fluorinated silicon copolymer finishing agent entering the preparation box 1 is blown away and distributed on the surface of the fabric substrate to modify the fabric substrate to obtain an anti-fouling fabric.

[0037] The interface 4 is set on the upper part of the right side wall of the preparation box 1, and a positioning groove 9 for supporting the top cover 2 is formed inwardly on the upper surface of the inner cavity of the preparation box 1, and a circular arc guide surface 10 is provided on the left side wall of the inner cavity of the preparation box 1.

An electric heating and drying component 12 is provided on the lower surface of the top cover 2.

[0038] Analysis of the above content: a high-pressure blowing fan is preset externally, and the air outlet of the high-pressure blowing fan is connected through an air pipe pre-interface 4. High-pressure air enters the interface 4 based on the air pipe, and enters the preparation box 1 from the interface 4. The nano-scale fluorinated polyacrylate functional finishing agent or the organic fluorinated silicon copolymer finishing agent falling from the storage box 3 enters the inner cavity of the preparation box 1 through the lower pipe. A flow valve is set on the lower pipe to control the falling flow rate of the nano-scale fluorinated polyacrylate functional finishing agent or the organic fluorinated silicon copolymer finishing agent. The high-pressure air blows the falling nano-scale fluorinated polyacrylate functional finishing agent or the organic fluorinated silicon copolymer finishing agent, so that the nano-scale fluorinated polyacrylate functional finishing agent or the organic fluorinated silicon copolymer finishing agent is dispersed into the preparation box 1.

[0039] The fabric substrate is laid on the support bar 11 in the preparation box 1, and the nano-scale fluorinated polyacrylate functional finishing agent or organic fluorine-silicon copolymer finishing agent blown by high-pressure gas is dispersed on the surface of the fabric substrate, thereby modifying the fabric substrate.

[0040] The nanometer-scale fluorinated polyacrylate functional finishing agent or the organic fluorinated silicon copolymer finishing agent entering into the preparation box 1 is blown from right to left and flows to the left on the upper surface of the fabric substrate. After contacting the arc guide surface 10, it changes direction and flows back to the right from the lower side of the fabric substrate. At this time, the lower surface of the fabric substrate is contacted and modified, and finally output from the discharge slot 6 and enters the collection box 5. The liquid part of the nanometer-scale fluorinated polyacrylate functional finishing agent or the organic fluorinated silicon copolymer finishing agent is concentrated in the collection box 5, and the air is discharged from the air outlet 8.
