Description

Technical Field

[0001] This invention relates to the field of sun-protective clothing fabric technology, specifically to a sun-protective clothing fabric and its preparation process. Background Technology

[0002] Sunscreen is one of the important ways to help us prevent irreversible aging. Regardless of whether there is sunscreen or not, the skin will experience the following after being exposed to ultraviolet rays for a long time: First, the skin will get hot, and the temperature will rise, resulting in redness. If the skin is not cooled down in time, it may leave red scars. The appearance of red scars indicates that the skin has been damaged inside. As the skin temperature rises, the pores will also enlarge, and the skin will gradually lose its elasticity, thus forming irreversible damage and making it prone to aging.

[0003] For example, the invention with application number CN202311395688.3 relates to a cooling and sun-protective fabric and its preparation method. The cooling and sun-protective fabric includes a hydrophilic fabric layer and a micro-nano sponge pore membrane layer bonded together. The micro-nano sponge pore membrane layer has interconnected micro-nano pores. The micro-nano sponge pore membrane layer contains nano-hybrid coated diatomaceous earth and a hydrophilic modifier, with the content of nano-hybrid coated diatomaceous earth being 15-25 wt% and the content of the hydrophilic modifier being 1-5 wt%. First, a micro-nano foaming adhesive is prepared using nano-hybrid coated diatomaceous earth and a hydrophilic modifier. Then, the micro-nano foaming adhesive is coated onto the hydrophilic fabric to obtain the cooling and sun-protective fabric. The preparation method of this invention uses sunlight reflection and strong capillary effect to quickly transfer sweat from the human body surface to the outer membrane surface of the fabric, forming a rapid evaporation and heat absorption effect, and quickly absorbing the sweat from the hydrophilic fabric layer, thus providing sun protection and a cooling effect. The product of this invention has excellent sunlight shielding and reflection effects, and is both breathable and comfortable to wear. However, when sun-protective clothing comes into contact with sweaty skin, it can become tightly adhered, reducing breathability and affecting its breathability when worn.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a sun protection clothing fabric and its manufacturing process. Summary of the Invention

[0005] The purpose of this invention is to provide a sun-protective clothing fabric and its manufacturing process, in order to solve the problem mentioned in the background art that when sun-protective clothing comes into contact with sweaty skin, it will adhere tightly, resulting in reduced breathability and affecting the breathability effect when worn.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sun-protective clothing fabric, wherein the sun-protective clothing fabric is woven from an upper yarn layer, a lower yarn layer, and a middle yarn layer. The upper yarn layer includes a first transverse yarn, a first nylon yarn, and a first longitudinal yarn. The outer surface of the first transverse yarn has a first longitudinal yarn, and a first nylon yarn is provided on one side adjacent to the first longitudinal yarn. The lower yarn layer includes a second transverse yarn, a second nylon yarn, and a second longitudinal yarn, and the outer surface of the second transverse yarn has a second longitudinal yarn. Nylon thread one is installed on one side of the surface. A middle layer yarn is woven between the upper yarn layer and the lower yarn layer. The middle layer yarn is a blend of cotton and modal yarn and protrudes from the inner layer of the upper and lower yarn layers. Both the first transverse thread and the first longitudinal thread are made of nylon and spandex. Both the second transverse thread and the second longitudinal thread are made of nylon and spandex. Nylon thread one is woven between two adjacent sets of the first longitudinal threads. Both nylon thread one and nylon thread two are 30D nylon yarn.

[0007] A manufacturing process for a sun-protective clothing fabric includes the following steps: Combing involves using a combing machine to remove short fibers and impurities from the upper and lower yarn layers, leaving behind impurity-free upper and lower yarn layers. The upper and lower yarn layers are then woven into a woven fabric, and a lint removal device is used to remove lint from both sides of the woven fabric. Washing involves placing the fabric, which consists of an upper and lower yarn layer woven together, in a washing solution, while the middle yarn layer is also placed in the washing solution. After dyeing and temperature control, the fabric woven from the upper and lower yarn layers and the middle yarn layer are dyed and fixed. The forming process involves drying the fabric woven from the upper and lower yarn layers after color fixing using a drying device, while the middle yarn layer is dried independently. After drying, the fabric is arranged and disinfected, and then the upper, lower, and middle yarn layers are combined and formed.

[0008] Preferably, the drying process employs zoned temperature control, the fabric woven from the upper and lower yarn layers is dried in a vacuum oven, and the drying temperature of the middle yarn layer is 200-230℃.

[0009] Preferably, the vacuum drying time is 3-4 hours.

[0010] Preferably, the molding process further includes adding an ultraviolet sterilization lamp during the molding and drying process.

[0011] Preferably, the fabric woven from the upper and lower yarn layers is placed in an acidic aqueous solution, while the middle yarn layer is placed in a neutral washing solution.

[0012] Preferably, the upper yarn layer, lower yarn layer and middle yarn layer are formed by knitting and sewing.

[0013] Preferably, the dyeing temperature of the fabric woven from the upper and lower yarn layers is maintained at 50-65℃, and the dyeing time is minutes.

[0014] Preferably, the washing time of the middle layer yarn is - minutes, and the washing temperature of the middle layer yarn is 60-90°C.

[0015] Preferably, the color fixing uses a color fixing agent, the color fixing temperature is 50-60°C, and the color fixing time is 10-20 minutes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the sun-protective clothing fabric and its preparation process, This invention uses woven fabric to create two independent fabrics: an upper yarn layer and a lower yarn layer. Both the upper and lower yarn layers are made of nylon and spandex, which provide excellent sun protection and UV protection. At the same time, the woven fabric makes the entire sun protection garment have a tight and solid texture, reducing sunlight transmission and further improving the sun protection effect. This invention features a middle layer of yarn protruding from the inner layers of the upper and lower yarn layers, creating a gap between them when they come into contact with the skin. This prevents the upper and lower yarn layers from completely adhering tightly to the skin surface, thus avoiding them from sticking to the skin and affecting breathability when sweating during exercise. Furthermore, the sun-protective fabric, formed by sewing the middle layer of yarn together with the upper and lower yarn layers, remains sturdy and is not prone to wear and tear even after prolonged use. Additionally, the upper and lower yarn layers can be dyed independently, allowing for reversible wear of the sun-protective clothing. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-2 The present invention provides a technical solution: A sun-protective clothing fabric is woven from an upper yarn layer 1, a lower yarn layer 2, and a middle yarn layer 3. The upper yarn layer 1 includes horizontal yarns 101, nylon yarns 102, and vertical yarns 103. The outer surface of the horizontal yarns 101 is provided with the vertical yarns 103, and one side of the adjacent vertical yarns 103 is provided with nylon yarns 102. Both the horizontal yarns 101 and the vertical yarns 103 are made of nylon and spandex. Both the horizontal yarns 101 and the vertical yarns 103 are made of nylon and spandex. The weaving process creates two independent fabrics: the upper yarn layer 1 and the lower yarn layer 2. Both layers are made of nylon and spandex, providing excellent sun protection and UV resistance. The woven fabric also creates a dense and robust texture, reducing sunlight transmission and further enhancing sun protection. The lower yarn layer 2 includes horizontal yarn 201, nylon yarn 202, and vertical yarn 203. The outer surface of the horizontal yarn 201 is provided with the vertical yarn 203. One side of the surface is fitted with nylon yarn 202. A middle layer yarn 3 is woven between the upper yarn layer 1 and the lower yarn layer 2. The middle layer yarn 3 is a blend of cotton and modal yarn, and it protrudes from the inner layer of the upper yarn layer 1 and the lower yarn layer 2. Nylon yarn 102 is woven between two adjacent sets of longitudinal yarns 103. Both nylon yarn 102 and nylon yarn 202 are 30D nylon yarns. The middle layer yarn 3 protrudes from the inner layer of the upper yarn layer 1 and the lower yarn layer 2, making the upper yarn layer 1... There is a gap between the upper yarn layer 1 and the lower yarn layer 2 when they are in contact with the skin, so as to prevent the upper yarn layer 1 and the lower yarn layer 2 from being completely and tightly attached to the skin surface. This also prevents the upper yarn layer 1 and the lower yarn layer 2 from sticking to the skin surface when sweating during exercise, which would affect breathability. In addition, the sun protection fabric formed by sewing the middle yarn layer 3 to the upper yarn layer 1 and the lower yarn layer 2 can remain strong during long-term use and is not easy to wear and tear. The forming also includes sewing the middle yarn layer 3 between the upper yarn layer 1 and the lower yarn layer 2. A manufacturing process for a sun-protective clothing fabric includes the following steps: Combing involves using a combing machine to remove short fibers and impurities from the upper yarn layer 1 and the lower yarn layer 2, leaving the upper yarn layer 1 and the lower yarn layer 2 free of impurities. Then, the upper yarn layer 1 and the lower yarn layer 2 are woven into a woven fabric, and a lint removal device is used to remove lint from both sides of the woven fabric. Washing involves placing the fabric woven from the upper yarn layer 1 and the lower yarn layer 2 in a washing solution, and placing the middle yarn layer 3 in a washing solution. The water solution in which the fabric woven from the upper yarn layer 1 and the lower yarn layer 2 is placed is acidic, while the water solution in which the middle yarn layer 3 is placed is neutral. After dyeing and temperature control, the fabric woven from the upper yarn layer 1 and the lower yarn layer 2, as well as the middle yarn layer 3, are dyed and fixed. The dyeing temperature of the fabric woven from the upper yarn layer 1 and the lower yarn layer 2 is maintained at 50-65℃, and the dyeing time is 20 minutes. The washing time of the middle yarn layer 3 is 10-15 minutes, and the washing temperature of the middle yarn layer 3 is 60-90°C. A fixing agent is used for fixing, and the fixing temperature is 50-60℃, and the fixing time is 10-20 minutes. The forming process involves drying the fabric woven from the upper yarn layer 1 and lower yarn layer 2 after color fixing using drying equipment, while the middle yarn layer 3 is dried independently. After drying, the fabric is arranged and disinfected. After disinfection, the upper yarn layer 1, lower yarn layer 2, and middle yarn layer 3 are combined and formed. The drying process uses zoned temperature control. The fabric woven from the upper yarn layer 1 and lower yarn layer 2 is dried in a vacuum oven, while the middle yarn layer 3 is dried at a temperature of 200-230℃ for 3-4 hours. The forming process also includes adding ultraviolet disinfection lamps during the forming and drying process. The combination of the upper yarn layer 1, lower yarn layer 2, and middle yarn layer 3 is formed using knitting and sewing.

[0021] In summary, the manufacturing process of this sun-protective clothing fabric involves first using a combing machine to remove short fibers and impurities from the upper yarn layer 1 and lower yarn layer 2, leaving the impurity-free upper yarn layer 1 and lower yarn layer 2. Then, the upper yarn layer 1 and lower yarn layer 2 are woven into a woven fabric, and a lint-removing device is used to remove lint from both sides of the woven fabric. After lint removal, the fabric is washed by placing the woven fabric of upper yarn layer 1 and lower yarn layer 2 in a washing solution, while the middle layer yarn 3 is also placed in the washing solution. The fabric is placed in an acidic aqueous solution, while the middle yarn 3 is placed in a neutral washing solution. After temperature control, the fabric woven from the upper yarn layer 1 and the lower yarn layer 2, as well as the middle yarn 3, are dyed, fixed, and dried using zoned temperature control. The fabric woven from the upper yarn layer 1 and the lower yarn layer 2 is dried in a vacuum oven for 3-4 hours, while the temperature of the middle yarn 3 is 200-230℃. The forming process also includes the addition of ultraviolet disinfection lamps during the forming and drying process to disinfect the processed fabric, making it easier to apply directly to the skin after processing. The process involves using a drying device to obtain a fabric woven from upper yarn layer 1 and lower yarn layer 2, along with a middle yarn layer 3. Then, through sewing, the upper yarn layer 1, lower yarn layer 2, and middle yarn layer 3 are combined to form the sun-protective clothing fabric. Furthermore, the weaving process creates two independent fabrics for upper yarn layer 1 and lower yarn layer 2, both made of nylon and spandex, providing excellent sun protection and UV resistance. The weaving process also results in a dense and firm texture, reducing sunlight transmission and further enhancing the sun protection effect. Secondly, the middle layer yarn 3 protrudes from the inner layer of the upper yarn layer 1 and the lower yarn layer 2, creating a gap between the upper yarn layer 1 and the lower yarn layer 2 when they are in contact with the skin. This prevents the upper yarn layer 1 and the lower yarn layer 2 from completely and tightly adhering to the skin surface, thus avoiding them from sticking to the skin surface during exercise and sweating, which would affect breathability. In addition, the sun-protective fabric formed by sewing the middle layer yarn 3 to the upper yarn layer 1 and the lower yarn layer 2 can remain sturdy during long-term use and is not prone to wear and tear.
