Description

Technical Field

[0001] This application relates to the field of textile processing technology, and in particular to a breathable, corrosion-resistant, and wrinkle-resistant double-layer knitted fabric. Background Technology

[0002] Most textile fabrics commonly found on the market today are single-layer structures. While these can meet the basic needs of daily wear, they exhibit significant limitations in specific environments. For instance, in high-temperature and high-humidity environments, single-layer fabrics have poor breathability, which can easily cause discomfort to the wearer. Furthermore, the corrosion resistance and wrinkle resistance of traditional fabrics are also unsatisfactory, especially when outdoor activities are frequent, these defects become more prominent. With the continuous improvement of consumers' requirements for product quality and technological advancements, the development of new multifunctional fabrics has become one of the current research hotspots.

[0003] To improve fabric functionality, the industry has proposed various improvement measures. On the one hand, adding functional fibers can enhance certain specific properties of the fabric. On the other hand, optimizing the weaving structure is also an important way to improve fabric performance. For example, changing the yarn arrangement or introducing three-dimensional weaving technology can increase the elasticity and comfort of the fabric. However, relying solely on fiber modification may sacrifice the fabric's feel and aesthetics. Secondly, existing structural designs often cannot effectively balance the contradiction between breathability and abrasion resistance. Moreover, most existing methods focus on enhancing a single function, making it difficult to meet multiple needs. Therefore, most improved fabrics still cannot meet the harsh conditions of long-term outdoor use, especially their durability in harsh environments still needs improvement.

[0004] Therefore, this application provides a breathable, corrosion-resistant, and wrinkle-resistant double-layer knitted fabric. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a breathable, corrosion-resistant, and wrinkle-resistant double-layer knitted fabric, overcoming the deficiencies of existing technologies. It aims to solve the problem that relying solely on fiber modification may sacrifice the fabric's feel and aesthetics. Secondly, existing structural designs often fail to effectively balance the contradiction between breathability and abrasion resistance. Furthermore, existing methods mostly focus on enhancing a single function, making it difficult to meet multiple needs. Therefore, most improved fabrics still cannot meet the harsh conditions of long-term outdoor use, especially the issue that their durability in harsh environments still needs improvement.

[0006] To achieve the above objectives, this application provides the following technical solution: a breathable, corrosion-resistant, and wrinkle-resistant double-layer knitted fabric, comprising an outer layer made of nylon filament knitting, an inner layer disposed below the outer layer, a connecting layer bonded between the outer and inner layers, the connecting layer being made of ultra-fine polyurethane fiber knitting, the inner layer comprising cotton fiber and lyocell fiber, the inner layer being made of a blend of cotton fiber and lyocell fiber knitting, and the interior of the outer layer being uniformly filled with several groups of silica microspheres, with pores formed between two groups of silica microspheres.

[0007] By adopting the above technical solution, the outer layer uses nylon filament as the base material and is manufactured through a special low-temperature treatment process. The outer layer is filled with silica microspheres, forming stable pores between two sets of silica microspheres to ensure good breathability and abrasion resistance. The inner layer is made of a blend of cotton and lyocell fibers. This combination not only improves the overall softness of the fabric but also enhances its moisture-wicking ability, significantly improving the comfort and quick-drying properties of the inner layer. Simultaneously, the ultra-fine polyurethane fiber layer has good elasticity, and the outer and inner layers are seamlessly connected through a bonding layer, ensuring the overall stability of the fabric. It also provides sufficient flexibility, forming a tight yet elastic composite that meets diverse usage needs. When the wearer is active, the heat and sweat generated by the body can be quickly conducted to the surface through the inner layer and discharged through the pores in the outer layer, keeping the skin dry. At the same time, the outer layer is made of nylon filament, which can resist the erosion of external chemicals and extend its service life. The double-layer fabric construction makes the overall structure both strong and flexible, not easy to wrinkle, and can maintain its original shape even after multiple washes. Ultimately, it achieves a comprehensive improvement in the fabric's breathability, corrosion resistance and wrinkle resistance.

[0008] As a preferred technical solution of this application, thermal insulation fibers are interwoven between the cotton fibers and the lyocell fibers, and the thermal insulation fibers are wool fibers.

[0009] By adopting the above technical solution, due to the large differences in climate in different regions, a small amount of heat-insulating fiber can be added to the inner layer in areas with lower temperatures, which can greatly improve the heat retention effect without affecting the breathability.

[0010] As a preferred technical solution of this application, the outer surface of the outer layer is provided with a plurality of sets of protrusions and grooves, the protrusions and grooves are arranged alternately, and the silica microspheres are located between two sets of opposite grooves.

[0011] By adopting the above technical solution, the outer layer is subjected to low-temperature treatment to generate protrusions and grooves on its surface, forming a nanoscale uneven microstructure, so as to better adsorb silica microspheres. At the same time, the combination of the outer layer and silica microspheres not only ensures excellent physical and mechanical properties, but also effectively blocks ultraviolet damage.

[0012] As a preferred technical solution of this application, the top surface of the outer layer is bonded with an anti-fouling layer, and the anti-fouling layer is made of polyester fiber.

[0013] By adopting the above technical solution, the polyester fiber has a good stain resistance effect, and the stain resistance layer can improve the stain resistance effect of this fabric.

[0014] As a preferred technical solution of this application, the inner layer is filled with several groups of phase change material particles.

[0015] By adopting the above technical solution, since there are large differences in climate in different regions, phase change material particles can be added to the inner layer in areas with higher temperatures. The phase change material particles absorb excess heat energy and slowly release it when the temperature drops, thus maintaining a stable body temperature for the wearer.

[0016] As a preferred technical solution of this application, liquid polyurethane solution is sprayed between the outer layer, the connecting layer and the inner layer, and the bonding method between the outer layer, the connecting layer and the inner layer is high-temperature curing.

[0017] By adopting the above technical solution, a thin layer of liquid polyurethane solution is sprayed between the two layers, and seamless bonding between the outer layer, the connecting layer, and the inner layer is achieved by high-temperature curing.

[0018] As a preferred technical solution of this application, the outer layer of nylon filament has a diameter of about 7 μm, the cotton fiber has a length of about 28 mm, the lyocell fiber has a length of about 51 mm, the mixing ratio of the two is 6:4, the average particle size of the silica microspheres is 0.5-1 μm, and the diameter of the ultrafine polyurethane fiber of the connecting layer is less than 0.1 mm.

[0019] By adopting the above technical solutions, the outer layer, cotton fiber, and lyocell fiber help improve the comfort and moisture absorption of this fabric, the silica microspheres improve the breathability of this fabric, and the connecting layer improves the elasticity of this fabric.

[0020] The beneficial effects of this application are:

[0021] 1. The outer layer uses nylon filament as the base material and is manufactured through a special low-temperature treatment process. The outer layer is filled with silica microspheres, forming stable pores between two sets of silica microspheres, ensuring excellent breathability and abrasion resistance. The inner layer is made of a blend of cotton and lyocell fibers. This combination not only enhances the overall softness of the fabric but also strengthens its moisture-wicking ability, significantly improving the comfort and quick-drying properties of the inner layer. Simultaneously, the ultra-fine polyurethane fiber layer has good elasticity. The outer and inner layers are seamlessly connected by a bonding layer, ensuring both the overall stability of the fabric and providing… Its sufficient flexibility forms a tight yet elastic composite that meets diverse usage needs. When the wearer is active, the heat and sweat generated by the body can be quickly conducted to the surface through the inner layer and discharged through the pores in the outer layer, keeping the skin dry. At the same time, the outer layer is made of nylon filament, which can resist the erosion of external chemicals and extend its service life. The double-layer fabric construction makes the overall structure both strong and flexible, not easy to wrinkle, and can maintain its original shape even after multiple washes. Ultimately, it achieves a comprehensive improvement in the fabric's breathability, corrosion resistance and wrinkle resistance.

[0032] Due to significant climate differences in different regions, a small amount of insulating fiber 5 can be added to the inner layer 2 in areas with lower temperatures to improve the warmth retention without affecting breathability. Polyester fiber has good stain resistance, and the stain-resistant layer 6 further enhances the stain resistance of this fabric.

A thin layer of liquid polyurethane solution is sprayed between the two layers, and seamless bonding between the outer layer 1, the connecting layer 3, and the inner layer 2 is achieved by high-temperature curing.

[0035] Working principle: The outer layer 1 uses nylon filament as the base material and is made through a special low-temperature treatment process. The outer layer 1 is filled with silica microspheres 4, forming stable pores 8 between two sets of silica microspheres 4, ensuring good breathability and abrasion resistance.

Simultaneously, the ultra-fine polyurethane fiber layer has good elasticity. The outer layer 1 and inner layer 2 are seamlessly connected by a connecting layer 3, ensuring the overall stability of the fabric while providing sufficient flexibility, forming a tight yet elastic composite. The body meets diverse usage needs. When the wearer is active, the heat and sweat generated by the body can be quickly conducted to the surface through the inner layer 2 and discharged through the air holes 8 in the outer layer 1, keeping the skin dry.

Due to the large differences in climate in different regions, a small amount of heat-insulating fiber 5 can be added to the inner layer 2 in areas with lower temperatures, which can greatly improve the warmth effect without affecting the breathability.

At the same time, by combining the outer layer 1 with silica microspheres 4, not only are excellent physical and mechanical properties guaranteed, but ultraviolet rays can also be effectively blocked. Polyester fiber has a good anti-fouling effect, and the anti-fouling layer 6 can improve the anti-fouling effect of this fabric.

The phase change material particles 7 absorb excess heat energy and release it slowly when the temperature drops, maintaining a stable body temperature for the wearer. A thin layer of liquid polyurethane solution is sprayed between the two layers, and high-temperature curing is used to achieve seamless bonding between the outer layer 1, the connecting layer 3, and the inner layer 2.
