Description

Technical Field

[0001] The present invention relates to the technical field of textile fabrics, and more specifically, to a highly elastic antibacterial and skin-friendly fabric and a preparation method thereof. Background Art

[0002] A textile fabric is a fabric carefully made from a variety of fabric fibers according to a specific weaving process, which can be mainly divided into two categories: warp knitting and weft knitting. This kind of fabric plays a crucial role in human daily life and is widely used in making various products such as clothes, bed sheets, towels, etc., and has various practical functions such as keeping warm and covering the body.

[0003] With the continuous progress of technology and the continuous development of society, people's functional requirements for textile fabrics are also increasing day by day. When modern consumers choose fabrics, they tend to choose those with good elasticity and comfortable wearing. Since most daily necessities made of textile fabrics, such as clothes, bed sheets, socks, etc., will directly come into intimate contact with the human skin, people have put forward more stringent requirements for the safety of textile fabrics.

[0004] In the field of protective gear, people's requirements for the comfort, elasticity and antibacterial properties of fabrics are getting higher and higher. Traditional fabrics often have difficulty meeting these requirements simultaneously, especially in the field of protective gear that needs to be in long-term contact with the skin, such as sports knee pads and elbow pads. These protective gears not only require the fabric to have high elasticity to adapt to different body types and activity intensities, but also require the fabric to have excellent antibacterial properties to keep the skin clean and healthy.

[0005] However, most of the common fabrics on the market currently use a single fabric fiber and a single weaving method, resulting in the product texture being too hard and the elasticity being insufficient. This not only seriously affects the wearing comfort of the textile fabric, but also after multiple wearings, washings and sunlight irradiations, the fabric is prone to problems such as elastic relaxation and dimensional deformation, thus greatly shortening its service life. In addition, this kind of warp-knitted fabric belongs to a porous structure, and the fabric fiber used as the weaving raw material is a kind of polymer with a hydrophilic surface in terms of its chemical nature. This structural characteristic makes it easy for microorganisms to attach to it, thereby reducing the safety of the fabric.

[0006] In view of the above-mentioned many problems, there is an urgent need for technological innovation and improvement to develop a new type of fabric that can combine high elasticity, antibacterial properties and skin-friendly characteristics to meet the pursuit of modern consumers for a high-quality life. Summary of the Invention

[0007] The object of the present invention is to provide a highly elastic antibacterial skin-friendly fabric and its preparation method. This fabric not only maintains excellent elasticity but also has outstanding antibacterial properties, ensuring that the fabric can quickly return to its original state after multiple stretches, thereby maintaining the shape stability and wearing comfort of the clothing. In addition, through an innovative preparation method, copper ion fibers are evenly dispersed in the copper ion skin-friendly antibacterial inner layer and the copper ion highly elastic outer layer on the surface, effectively inhibiting the growth of bacteria and bringing a healthier wearing experience to users. This fabric also has good air permeability and moisture absorption, and can keep the skin dry even after strenuous exercise, avoiding discomfort caused by sweat accumulation, and is particularly suitable for sports clothing and protective gear.

[0008] To achieve the above object, the present invention first discloses a technical solution:

[0009] A highly elastic skin-friendly antibacterial fabric, which is characterized in that it includes a copper ion skin-friendly antibacterial inner layer, a buffer structure, an acrylate anti-wrinkle layer, an adhesive layer, and a copper ion highly elastic outer layer arranged in sequence from inside to outside; wherein, the copper ion skin-friendly antibacterial inner layer and the acrylate anti-wrinkle layer are stitched and connected through the buffer structure; and the acrylate anti-wrinkle layer and the copper ion highly elastic outer layer are adhered into one body through the adhesive layer.

[0010] Furthermore, both the copper ion skin-friendly antibacterial inner layer and the copper ion highly elastic outer layer use a blended yarn made of polyester fiber and copper ion fiber as the warp yarn, and natural cotton yarn as the weft yarn, and are made through a weaving process of alternating warp and weft.

[0011] Furthermore, the buffer structure includes a number of evenly distributed buffer protrusions, which are made of a blend of spandex, nylon, and natural cotton yarn, and are respectively connected to the skin-friendly layer and the acrylate anti-wrinkle layer through weft knitting.

[0012] Furthermore, sodium silicate is filled in the filling chamber inside the buffer protrusion.

[0013] Furthermore, the ratio of the blended yarn made of polyester fiber and copper ion fiber used in the copper ion skin-friendly antibacterial inner layer to natural cotton yarn is 65:35.

[0014] Furthermore, the ratio of the blended yarn made of polyester fiber and copper ion fiber used in the copper ion highly elastic outer layer to natural cotton yarn is 80:20.

[0015] Furthermore, the adhesive layer uses JL-606 dry-type water-based laminating adhesive as the adhesive, and rosin resin needs to be added as a tackifier to increase the viscosity.

[0016] Furthermore, the ratio of the JL-606 dry-type water-based laminating adhesive to rosin resin is 95:5.

[0017] Furthermore, for the outer surface of the highly elastic outer layer of copper ions, fluorocarbon resin is used as a treatment agent for waterproof and oil-proof treatment.

[0018] Secondly, based on the foregoing description, the present invention also discloses a preparation method for preparing the above-mentioned highly elastic skin-friendly antibacterial fabric, which is characterized by including the following steps:

[0019] Step S1 Weaving process:

[0020] S101: Blend polyester fiber and copper ion fiber into a blended yarn;

[0021] S102: Use the blended yarn as the warp yarn and natural cotton yarn as the weft yarn, and through the warp and weft alternating knitting process, respectively make the copper ion skin-friendly antibacterial inner layer and the highly elastic outer layer of copper ions according to a predetermined ratio;

[0022] S103: Obtain a number of buffer protrusions by blending spandex, nylon and natural cotton yarn;

[0023] S104: Attach a buffer structure composed of a number of buffer protrusions to the outer surface of the copper ion skin-friendly antibacterial inner layer, and stitch and connect each buffer protrusion to the copper ion skin-friendly antibacterial inner layer and the acrylate anti-wrinkle layer respectively through weft knitting, and at the same time fill sodium silicate inside each buffer protrusion of the buffer structure;

[0024] S105: Coat JL-606 dry water-based composite film adhesive as an adhesive layer between the acrylate anti-wrinkle layer and the highly elastic outer layer of copper ions, and add rosin resin as a tackifier to complete the preparation of the fabric blank;

[0025] Step S2 Pre-setting process:

[0026] S201: Perform heat setting on the woven fabric blank, and perform preliminary setting on its width and gram weight. The setting temperature is set at 180-220 °C, the setting time is 45 min, and the setting tension is 50 N;

[0027] Step S3 Raising process:

[0028] S301: Use professional raising equipment to perform fine raising treatment on the inner and outer surfaces of the fabric blank to form a layer of delicate short fluff to improve the warmth retention performance and texture of the fabric;

[0029] Step S4 Dyeing process:

[0030] S401: Singe the fabric blank after raising treatment, and then perform desizing treatment with PVA in warm water at 50-60 °C;

[0031] S402: Add dyes for dyeing. After dyeing is completed, use clear water, glacial acetic acid, fluorescent brightener DT, and 601 detergent as the scouring agent for cleaning;

[0032] Step S5 Drying process:

[0033] S501: Conduct a drying treatment on the dyed fabric, and the drying temperature is 110 - 120 °C;

[0034] Step S6 Post-setting process:

[0035] S601: Add a cationic softener to the dried fabric and then dry it again for final setting. The setting temperature is 150 - 180 °C.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] (1) In the present invention, both the copper ion skin-friendly antibacterial inner layer and the copper ion high-elastic outer layer select polyester fiber, copper ion fiber, and natural cotton yarn as textile raw materials. Specifically, a blended yarn of polyester fiber and copper ion fiber is used as the warp yarn, and natural cotton yarn is used as the weft yarn, and it is made by the weaving method of alternating warp and weft, thereby significantly improving the antibacterial performance and comfort of the fabric;

[0038] (2) Using polyester fiber as the elastic fiber, first of all, the main component of polyester is polyethylene terephthalate (PET). This polyester itself does not have a hydrophilic surface, so it lacks hydrophilicity and can prevent the attachment of microorganisms to a certain extent, thus effectively avoiding the growth of bacteria; secondly, the polyester fiber is blended with copper ion fiber to form a blended yarn. Through this treatment, the polyester fiber endows the blended yarn with significant antibacterial performance based on the principle of denaturing proteins by heavy metals;

[0039] (3) Considering that the copper ion skin-friendly antibacterial inner layer will directly contact the skin, the ratio of polyester fiber to cotton fiber selected for this layer is 65:35. This not only ensures the elasticity and softness of the fabric but also ensures that the copper ion skin-friendly antibacterial inner layer can fully exert its antibacterial and skin-friendly effects. The addition of polyester fiber endows the fabric with good wrinkle resistance and abrasion resistance; while the incorporation of cotton fiber improves the air permeability and skin-friendly property of the fabric. This scientific ratio enables the high-elastic antibacterial and skin-friendly fabric of the present invention to have excellent antibacterial performance and skin-friendly effects while maintaining comfort and softness, fully meeting the needs of modern people for high-quality textile fabrics;

[0040] (4) The ratio of the blended yarn made of polyester fiber and copper ion fiber used in the high-elastic outer layer of copper ions to natural cotton yarn is 80:20. This blending ratio enables the fabric to possess both the high elasticity and abrasion resistance of polyester fiber, incorporate the antibacterial function of copper ion fiber, and at the same time, the addition of natural cotton yarn enhances the comfort and breathability of the fabric. The copper ions in the copper ion fiber of the outer layer can further inhibit the growth of bacteria, enhance the overall antibacterial effect of the fabric, extend the service life, ensure continuous hygiene and health during daily wearing, and truly achieve all-round protection of high-quality fabrics;

[0041] (5) The buffer structure composed of multiple buffer protrusions has excellent elasticity. This structure can not only effectively absorb external force impacts but also quickly return to its original state after being compressed, thus ensuring the durability and comfort of the fabric. In addition, the design of the buffer protrusions improves the breathability of the fabric surface, reduces sweat accumulation, and further optimizes the wearing experience. At the same time, the inside of the buffer protrusions is filled with sodium silicate, which has excellent hygroscopicity and antibacterial properties. It can not only efficiently absorb sweat, keep the skin dry, but also effectively prevent the growth of bacteria, ensuring the hygiene during long-term wearing;

[0042] (6) The addition of the acrylate anti-wrinkle layer enables the fabric to still maintain a smooth and new appearance even after long-term use and multiple washes. Its special chemical structure endows the fabric with excellent anti-wrinkle performance, effectively resists wrinkles caused by daily friction and pressure, and ensures the beauty and durability of the clothing. At the same time, the polymer chain structure of acrylate has good elasticity, providing additional support for the fabric, making it more wear-resistant and wash-resistant, and extending the service life of the fabric.

[0047] In order to make the technical problems, technical solutions, and advantages to be solved by the present invention clearer, the following will be described in detail in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0048] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It 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. Therefore, it should not be construed as a limitation to the present invention. In addition, in the description of the present invention, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0049] Figure 1 and Figure 2 The first embodiment of the present invention is presented: a highly elastic skin-friendly antibacterial fabric, comprising a copper ion skin-friendly antibacterial inner layer 1, a buffer structure, an acrylate anti-wrinkle layer 3, an adhesive layer 4, and a copper ion highly elastic outer layer 5 arranged in sequence from inside to outside; wherein, the copper ion skin-friendly antibacterial inner layer 1 and the acrylate anti-wrinkle layer 3 are stitched and connected through the buffer structure; and the acrylate anti-wrinkle layer 3 and the copper ion highly elastic outer layer 5 are adhered together through the adhesive layer 4.

[0050] As Figure 2 shown, in specific implementation, both the copper ion skin-friendly antibacterial inner layer 1 and the copper ion highly elastic outer layer 5 adopt a blended yarn 101 made of a blend of polyester fiber and copper ion fiber as the warp yarn, and natural cotton yarn 102 as the weft yarn, and are made through a weaving process of alternating warp and weft. Among them, the polyester fiber has excellent wear resistance and anti-wrinkle properties, and the copper ion fiber has antibacterial and skin-friendly characteristics. After blending, the overall performance of the fabric can be effectively improved. The addition of natural cotton yarn 102 endows the fabric with better moisture absorption and breathability, making it more comfortable to wear. During the weaving process, the alternating arrangement of the warp and weft yarns makes the fabric structure tight and elastic, and can meet the needs of different body types.

[0051] In this embodiment, the buffer structure includes a number of buffer protrusions 2 evenly distributed. The buffer protrusions 2 are made of a blend of spandex, nylon, and natural cotton yarn 102, and are respectively connected to the skin-friendly layer and the acrylate anti-wrinkle layer 3 through weft knitting. The setting of these buffer protrusions 2 not only enhances the elasticity of the fabric in the vertical direction but also effectively disperses the impact force on the fabric from the outside, improving the comfort and fit during wearing. Spandex, with its excellent elasticity, enables the fabric to adapt to various degrees of stretching and maintain the stable shape of the fabric; nylon, with its wear-resistant and high-strength characteristics, enhances the durability of the fabric; and the addition of natural cotton yarn 102 further improves the softness and breathability of the fabric, making the wearing experience more natural and skin-friendly. In addition, the knitting method of weft knitting makes the connection between the buffer protrusions 2 and the skin-friendly layer and the acrylate anti-wrinkle layer 3 more firm, not easily off-line or deformed, thus ensuring the overall quality and stability of the fabric.

[0052] Specifically, sodium silicate is filled in the filling chamber inside the buffer protrusion 2. As an excellent antibacterial agent, sodium silicate can effectively inhibit the growth of bacteria. At the same time, its excellent moisture absorption performance can also help regulate the humidity of the fabric, keeping the skin dry. In addition, the design of the filling chamber inside the buffer protrusion 2 enables the sodium silicate to be evenly distributed, further improving the antibacterial effect and comfort of the fabric.

[0053] The unique feature of the copper ion skin-friendly antibacterial inner layer 1 is that it uses a blended yarn 101 made of a blend of polyester fiber and copper ion fiber. After being verified by the applicant's experiments, the optimal ratio of this blended yarn 101 to natural cotton yarn 102 is set at 65:35. This ratio ensures that the copper ion skin-friendly antibacterial inner layer 1 not only has the wear-resistant and anti-wrinkle properties of polyester fiber, the antibacterial and skin-friendly characteristics of copper ion fiber, but also integrates the softness, breathability, and skin-friendly feeling of natural cotton yarn 102, bringing a more comfortable and healthy wearing experience to users.

[0054] Similarly, the copper ion highly elastic outer layer 5 uses a blended yarn 101 made of a blend of polyester fiber and copper ion fiber, and the ratio to natural cotton yarn 102 is set at 80:20. Due to its unique antibacterial properties, copper ion fiber can effectively inhibit the growth of bacteria, providing a healthier skin contact environment for the wearer. Polyester fiber is famous for its high elasticity and wear resistance, making the entire outer fabric have good elasticity and durability while maintaining antibacterial properties. The addition of natural cotton yarn 102 further improves the breathability and comfort of the fabric, allowing the wearer to enjoy a healthy antibacterial effect while also feeling a natural and skin-friendly wearing experience. The selection of this blending ratio is the best ratio obtained after multiple tests and optimizations, aiming to maximize the fabric performance.

[0055] In specific applications, the adhesive layer 4 uses JL-606 dry water-based laminating adhesive as the adhesive, and rosin resin needs to be added as a tackifier to increase the viscosity. The addition of rosin resin not only enhances the adhesion but also significantly improves the heat resistance and water resistance of the adhesive layer 4, ensuring its stability and durability in various environments. In addition, the environmental protection characteristics of JL-606 dry water-based laminating adhesive make the entire production process more environmentally friendly, meeting the dual requirements of modern consumers for health and environmental protection.

[0056] The addition amount of rosin resin is precisely calculated to enhance the adhesion without affecting the softness and breathability of the fabric. Through this optimized combination, the adhesive layer 4 can still maintain excellent adhesion in high-temperature and high-humidity environments, further improving the stability and durability of the fabric under extreme conditions, and ensuring that users can enjoy a consistent comfortable experience in different climates. The environmental protection characteristics of rosin resin and its compatibility with JL-606 adhesive enable the adhesive layer 4 to improve performance without damaging the original texture of the fabric.

[0057] The precise ratio ensures the stability of the adhesive layer 4 at different temperatures and humidities, extends the service life of the fabric, and provides users with a durable and comfortable wearing experience. In multiple experiments, the applicant found that the addition ratio of rosin resin has a significant impact on the adhesion effect. After repeated debugging, the final determined optimal ratio of JL-606 dry water-based laminating adhesive to rosin resin is 95:5. This ratio not only significantly improves the adhesion of the adhesive layer 4 but also ensures that the softness and breathability of the fabric are not affected. Experimental data shows that in high-temperature and high-humidity environments, the adhesion strength of the adhesive layer 4 is increased by 25%, while maintaining the comfort of the fabric. This optimized result enables the product to still provide a stable wearing experience under extreme climate conditions, meeting the needs of users for high-quality fabrics.

[0058] Preferably, the outer surface of the copper ion high-elastic outer layer 5 is treated with fluorocarbon resin as a treatment agent for waterproof and oil-proof treatment. After treatment, the copper ion high-elastic outer layer 5 not only maintains its original high elasticity and antibacterial properties but also significantly improves its waterproof and oil-proof capabilities. Such treatment enables the fabric to still maintain a good use state in humid or oily environments, effectively preventing the penetration of moisture and oil, thereby extending the service life of the fabric and improving the wearing comfort.

[0059] In order to further enhance the antibacterial effect of the fabric, in some other embodiments, an antibacterial agent can be sprayed on the copper ion skin-friendly antibacterial inner layer 1 and the copper ion high-elastic outer layer 5. This antibacterial agent can not only act synergistically with the copper ion fiber to improve the antibacterial performance, but also effectively inhibit the growth of bacteria, providing a healthier wearing environment for the wearer. At the same time, the outer layer of the fabric can also be treated with anti-ultraviolet, enabling it to effectively block the invasion of ultraviolet rays and protect the skin from damage. The addition of these special treatments makes our high-elastic antibacterial skin-friendly fabric more competitive in the market and meets the needs of consumers for high-quality and multi-functional fabrics.

[0060] Based on the foregoing description, this embodiment also discloses a preparation method for preparing the above-mentioned high-elastic skin-friendly antibacterial fabric, including the following steps:

[0061] Step S1 Weaving process:

[0062] S101: Blending polyester fiber and copper ion fiber into a blended yarn 101;

[0063] S102: Using the blended yarn 101 as the warp yarn and natural cotton yarn 102 as the weft yarn, through the warp and weft alternating knitting process, and respectively making the copper ion skin-friendly antibacterial inner layer 1 and the copper ion high-elastic outer layer 5 according to a predetermined ratio;

[0064] S103: Mixing spandex, nylon and natural cotton yarn 102 to obtain a number of buffer protrusions 2;

[0065] S104: Attaching a buffer structure composed of a number of buffer protrusions 2 to the outer surface of the copper ion skin-friendly antibacterial inner layer 1, and respectively sewing and connecting each buffer protrusion 2 with the copper ion skin-friendly antibacterial inner layer 1 and the acrylate anti-wrinkle layer 3 through weft knitting, and at the same time filling sodium silicate inside each buffer protrusion 2 of the buffer structure;

[0066] S105: Coating JL-606 dry water-based compound film adhesive as the adhesive layer 4 between the acrylate anti-wrinkle layer 3 and the copper ion high-elastic outer layer 5, and adding rosin resin as a tackifier to complete the preparation of the fabric blank;

[0067] Step S2 Pre-setting process:

[0068] S201: Thermally setting the woven fabric blank, preliminarily setting its width and gram weight, setting the setting temperature at 180 - 220 °C, the setting time at 45 min, and the setting tension at 50 N;

[0069] Step S3 Raising process:

[0070] S301: Using professional raising equipment to finely raise the inner and outer surfaces of the fabric blank to form a layer of delicate short fluff to improve the warmth retention performance and texture of the fabric;

[0071] Step S4 Dyeing Process:

[0072] S401: Singe the fabric grey cloth after napping treatment, and after completion, perform desizing treatment with PVA in warm water at 50 - 60 °C;

[0073] S402: Add dyes for dyeing, and after dyeing is completed, use clear water, glacial acetic acid, fluorescent brightener DT, and 601 detergent as a scouring agent for cleaning;

[0074] Step S5 Drying Process:

[0075] S501: Dry the dyed fabric, and the drying temperature is 110 - 120 °C;

[0076] Step S6 Post - setting Process:

[0077] S601: Add a cationic softener to the dried fabric and then dry it again for final setting, and the setting temperature is 150 - 180 °C.

[0078] Among them, the buffer structure in step S104 can effectively improve the three - dimensional sense and air permeability of the fabric. At the same time, the filling of sodium silicate makes the fabric have better elasticity and resilience during use. In step S201, the heat - setting treatment can make the size of the fabric grey cloth more stable and not easily deformed, thus ensuring the quality of the final fabric. In addition, the napping treatment in step S301 can not only increase the warmth - retention property of the fabric, but also improve the softness and skin - friendliness of the fabric. In step S402, using appropriate dyes and scouring agents for dyeing and cleaning can make the fabric have bright and lasting colors while maintaining a good hand feeling. Finally, the use of the cationic softener in step S601 can further increase the softness and comfort of the fabric, making the final high - elastic antibacterial skin - friendly fabric more suitable for human wear.

[0079] It is worth mentioning that in some other embodiments, step S106 is also included. In step S106, an antibacterial agent is introduced, and this antibacterial agent can effectively inhibit the growth of a variety of harmful microorganisms, thus ensuring that the fabric has a lasting antibacterial property. In addition, step S602 is also included. In step S602, the copper - ion skin - friendly antibacterial inner layer 1 is further subjected to a skin - friendly treatment, and a natural plant extract is used as a skin - friendly agent and sprayed onto the inner surface of the copper - ion skin - friendly antibacterial inner layer 1. This skin - friendly agent is rich in various ingredients beneficial to the skin and can continuously release during use, providing additional skin - care effects for the wearer.

[0080] In summary, in the present invention, both the copper ion skin-friendly antibacterial inner layer 1 and the copper ion highly elastic outer layer 5 are made of polyester fiber, copper ion fiber and natural cotton yarn 102 as textile raw materials. Specifically, a blended yarn 101 of polyester fiber and copper ion fiber is used as the warp yarn, and natural cotton yarn 102 is used as the weft yarn, and it is made by a weaving method of alternating warp and weft, thereby significantly improving the antibacterial performance and comfort of the fabric; polyester fiber is used as the elastic fiber.

The polyester fiber treated in this way endows the blended yarn 101 with significant antibacterial properties by using the principle of heavy metals denaturing proteins; considering that the copper ion skin-friendly antibacterial inner layer 1 will directly contact the skin, the ratio of polyester fiber to cotton fiber selected for this layer is 65:35. This not only ensures the elasticity and softness of the fabric, but also ensures that the copper ion skin-friendly antibacterial inner layer 1 can fully exert its antibacterial and skin-friendly effects. The addition of polyester fiber endows the fabric with good wrinkle resistance and wear resistance; while the incorporation of cotton fiber improves the breathability and skin-friendly property of the fabric.

S102: Use the blended yarn as the warp yarn and natural cotton yarn as the weft yarn, and respectively make the copper ion skin-friendly antibacterial inner layer and the copper ion highly elastic outer layer through a weaving process of alternating warp and weft according to a predetermined ratio. S103: Spin a number of buffer protrusions from spandex, nylon, and natural cotton yarn. S104: Attach a buffer structure composed of a number of buffer protrusions to the outer surface of the copper ion skin-friendly antibacterial inner layer, and respectively stitch and connect each buffer protrusion to the copper ion skin-friendly antibacterial inner layer and the acrylate anti-wrinkle layer through weft knitting, and at the same time fill sodium silicate inside each buffer protrusion of the buffer structure. S105: Coat JL-606 dry water-based laminating adhesive between the acrylate anti-wrinkle layer and the copper ion highly elastic outer layer as the adhesive layer, and add rosin resin as a tackifier to complete the preparation of the fabric embryo. Step S2 Pre-setting process: S201: Perform heat setting on the woven fabric embryo, preliminarily set its width and gram weight, the setting temperature is set at 180 - 220 °C, the setting time is 45 min, and the setting tension is 50 N. Step S3 Raising process: S301: Use professional raising equipment to finely raise the inner and outer surfaces of the fabric embryo to form a layer of delicate short fluff to improve the warmth retention performance and texture of the fabric. Step S4 Dyeing process: S401: Singe the fabric embryo after raising treatment, and then perform desizing treatment with PVA in warm water at 50 - 60 °C. S402: Add dyes for dyeing. After dyeing is completed, use clear water, glacial acetic acid, fluorescent brightener DT, and 601 detergent as the scouring agent for cleaning; Step S5 Drying process: S501: Perform drying treatment on the dyed fabric. The drying temperature is 110 - 120 °C; Step S6 Post-setting process: S601: Add a cationic softener to the dried fabric and then dry it again for final setting. The setting temperature is 150 - 180 °C.
