[0043] Firstly, this application provides a waterproof jacket fabric to address the problems of existing waterproof jacket fabrics not being able to simultaneously satisfy waterproof and breathable properties, and not being washable. The waterproof jacket fabric provided in this application will be described below with reference to the accompanying drawings.

[0044] Figure 1 This is a schematic diagram of the structure of a windbreaker fabric according to an embodiment of the present invention. Figure 2 This is a structural schematic diagram of the windbreaker fabric according to another embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the jacket fabric includes a nylon fabric layer 110, a waterproof and breathable layer 100, and a nylon PVC layer 120 stacked sequentially. The waterproof and breathable layer 100 includes a microporous membrane 101, a ceramic layer 102 stacked on one side of the microporous membrane 101, and a polyvinyl alcohol layer 103 stacked on the surface of the ceramic layer 102. This application does not limit the direction in which the microporous membrane 101, ceramic layer 102, and polyvinyl alcohol layer 103 are stacked in the waterproof and breathable layer 100; they can be stacked as follows: Figure 1 As shown, the nylon ductile material layer 120 is attached to the surface of the polyvinyl alcohol layer 103, or it can be done as follows: Figure 2 As shown, the nylon fabric layer 110 is attached to the surface of the polyvinyl alcohol layer 103.

[0045] The fabric layer of the jacket should have wear resistance and also have windproof and waterproof functions. Compared with polyester, the nylon fabric layer 110 has excellent wear resistance and light texture, which can better meet the lightweight demand of the jacket.

[0046] In outdoor activities, the jacket often faces the erosion of rain and snow water. Although the nylon fabric layer 110 meets the basic demand of wear resistance, it is difficult to meet the demand of waterproof and moisture permeability. Therefore, the waterproof and moisture permeable layer 100 is arranged between the nylon fabric layer 110 and the nylon cordele layer 120, which helps to discharge sweat and block the entry of water during outdoor activities, keeping the inner surface of the clothes dry.

[0047] The waterproof and moisture permeable layer 100 of the present application takes the microporous membrane 101 as the base film. Compared with other films with large pore or mesopore structures, the pore structure of the microporous membrane is much smaller than the size of the water droplet, which can effectively block the penetration of liquid water and allow water vapor molecules to pass smoothly, having good waterproof and moisture permeability. However, after washing, the microporous structure on the microporous membrane changes, increasing its permeability and gradually losing its waterproof function.

[0048] To solve this problem, the ceramic layer 102 and the polyvinyl alcohol layer 103 are sequentially stacked on one side surface of the microporous membrane 101. The ceramic layer 102 can enhance the surface polarity while retaining the microporous structure of the microporous membrane 101, which can better bond with the polyvinyl alcohol layer 103, so that the waterproof and moisture permeable layer 100 of the jacket is not easy to delaminate after washing, maintains good waterproof performance, and shows more excellent washing resistance.

[0049] The polyvinyl alcohol layer 103 of the present application has good waterproof performance.

[0050] Specifically, the polyvinyl alcohol layer 103 is a non-porous layer. The dense structure of the non-porous layer can make it completely free of physical pores, which can more effectively block the penetration of liquid water.

[0051] The nylon cordele layer 120 can support and protect the waterproof and moisture permeable layer 100, reduce the wear of the waterproof and moisture permeable layer 100, and avoid the blockage of the microporous structure of the waterproof and moisture permeable layer 100 caused by contact with other substances. At the same time, the nylon cordele layer 120 is closer to or directly contacts the human skin, and needs to have good ductility and elasticity, which can expand and contract with the body movement. The jacket is close-fitting and comfortable to wear. The nylon cordele used as the lining layer in the present application is delicate and soft in texture, comfortable in touch, has good air permeability and moisture permeability, can effectively regulate body temperature and keep dry and comfortable, and also maintains the excellent wear resistance and wash resistance of nylon, which is suitable for being used as the lining of laminated composite fabric.

[0052] In summary, the application adopts the lightweight nylon fabric layer 110 and the nylon cori material layer 120 to be compounded with the waterproof and moisture-permeable layer 100 with a specific layered structure to form the jacket fabric, wherein the waterproof and moisture-permeable layer 100 can provide good air permeability and moisture permeability and washing resistance for the jacket fabric, and the lightweight nylon fabric layer 110 and the nylon cori material layer 120 can make the jacket fabric have a lower grammage.

[0053] In some embodiments of the application, the nylon cori material layer 120 is attached to the surface of the polyvinyl alcohol layer 103. This arrangement can make the jacket fabric more resistant to washing.

[0054] In some embodiments of the application, the yarn fineness of the nylon fabric layer 110 is 7D-20D, and the yarn density is 300T-500T. The yarn fineness represents the fineness of the yarn, and the larger the value of the yarn fineness, the thicker the yarn. The yarn density represents the number of yarns per unit area or unit length. When the yarn fineness is constant, the larger the yarn density, the tighter the arrangement of yarns in the fabric, the more yarns per unit area, and the larger the grammage of the fabric. By limiting the yarn fineness and yarn density of the nylon fabric within the above range, the application can make the fabric meet the abrasion resistance requirements while having a low grammage, thereby reducing the total grammage of the jacket fabric. For example, the yarn fineness of the nylon fabric layer 110 can be 7D, 8D, 9D, 10D, 11D, 12D, 13D, 14D, 15D, 16D, 17D, 18D, 19D, 20D, or a range formed by any two of the above values, and the yarn density can be 300T, 350T, 400T, 450T, 500T, or a range formed by any two of the above values.

[0055] In some embodiments of the application, the grammage of the nylon fabric layer 110 is 20-40g / m 2 . The above arrangement can achieve the lightweight of the jacket fabric. For example, the grammage of the nylon fabric layer 110 can be 20g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , or a range formed by any two of the above values.

[0056] In some embodiments of the application, the thickness of the nylon fabric layer 110 is 0.02-0.2mm. The thickness of the nylon fabric layer 110 can be set according to the actual requirements of the fabric. For example, the thickness of the nylon fabric layer 110 can be 0.02mm, 0.05mm, 0.08mm, 0.1mm, 0.15mm, 0.2mm, or a range formed by any two of the above values.

[0057] In some embodiments of the present application, the yarn fineness of the nylon trilayer 120 is 10D-20D, and the yarn density is 80T-120T. Among them, compared with the nylon fabric layer 110, the yarn density of the nylon trilayer 120 is lower, which not only increases the air and moisture permeability of the nylon trilayer 120, but also makes the nylon trilayer 120 have a lower grammage, thereby reducing the overall weight of the jacket fabric. For example, the yarn fineness of the nylon trilayer can be 10D, 11D, 12D, 13D, 14D, 15D, 16D, 17D, 18D, 19D, 20D, or a range formed by any two of the above values. The yarn density can be 80T, 85T, 90T, 95T, 100T, 105T, 110T, 115T, 120T, or a range formed by any two of the above values.

[0058] In some embodiments of the present application, the grammage of the nylon trilayer 120 is 5-15 g / m 2 In the above range, the nylon trilayer 120 can meet the lightweight demand of the jacket fabric while meeting the basic wear-resistant support demand. For example, the grammage of the nylon trilayer 120 can be 5 g / m 2 , 8 g / m 2 , 10 g / m 2 , 13 g / m 2 , 15 g / m 2 , or a range formed by any two of the above values.

[0059] In some embodiments of the present application, the thickness of the nylon trilayer 120 is 0.02-0.2 mm. The thickness of the nylon trilayer 120 can be set according to the actual demand of the nylon trilayer 120. For example, the thickness of the nylon trilayer 120 can be 0.02 mm, 0.05 mm, 0.08 mm, 0.1 mm, 0.15 mm, 0.2 mm, or a range formed by any two of the above values.

[0060] In some embodiments of the present application, the bidirectional elongation at break of the nylon trilayer 120 and the nylon fabric layer 110 is >60%. The bidirectional elongation at break refers to the percentage of the increase in length in the longitudinal and transverse directions from the beginning of stretching to the breaking point during the bidirectional stretching, which is obtained by GB / T3923.1 test. Within the above numerical range, the nylon trilayer 120 exhibits better softness and bendability.

[0061] In some embodiments of the present application, the bending stiffness of the nylon fabric layer 110 is ≤0.1 cN·cm 2cm. It can be tested by KES-FB fabric style evaluation system. Within the above range, the stiffness of the fabric can be controlled to make the nylon fabric layer 110 have better flexibility.

[0062] In some embodiments of the present application, the grammage of the microporous film 101 is 1.0-2.3 g / m 2 . The above grammage range is conducive to the lightweight of the shell fabric. For example, the grammage of the microporous film 101 can be 1.0 g / m 2 , 1.2 g / m 2 , 1.4 g / m 2 , 1.6 g / m 2 , 1.8 g / m 2 , 2.0 g / m 2 , 2.2 g / m 2 , 2.3 g / m 2 or a range formed by any two of the above values.

[0063] In some embodiments of the present application, the thickness of the microporous film 101 is 3-10 μm. The thickness of the microporous film 101 can be set according to the actual needs of the microporous film 101. For example, the thickness of the microporous film 101 can be 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm or a range formed by any two of the above values.

[0064] In some embodiments of the present application, the porosity of the microporous film 101 is ≥40%. The porosity of the microporous film 101 is tested according to GB / T32363-2018. Within the above porosity range, it is conducive to maintaining good air and moisture permeability of the microporous film 101.

[0065] In some embodiments of the present application, the average pore size of the microporous film 101 is 10-150 nm. If the average pore size of the microporous film 101 is too low, the moisture permeability will be low, which is difficult to meet the moisture permeability requirement; if the average pore size is too large, the hydrostatic pressure will be too low, which is difficult to meet the waterproof requirement. For example, the average pore size of the microporous film 101 can be 10 nm, 20 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 90 nm, 100 nm, 110 nm, 120 nm, 130 nm, 140 nm, 150 nm or a range between any two of the above values. In the present application, the average pore size of the microporous film 101 is measured by GB / T32361-2015 bubble point method.

[0066] In some embodiments of the present application, the material of the microporous film 101 is polypropylene or polyethylene. Polypropylene and polyethylene themselves have high strength and good flexibility, and the microporous film made of them also has these advantages.

[0067] In some embodiments of the present application, the longitudinal breaking strength of the microporous membrane 101 is > 150 MPa, and the transverse breaking strength is > 20 MPa. The longitudinal breaking strength and the transverse breaking strength of the microporous membrane 101 within the above ranges are advantageous for maintaining good durability and stability of the shell fabric of the storm coat, and the shell fabric is not prone to breakage. Specifically, the microporous membrane can be selected from commercially available lithium battery separators.

[0068] In some embodiments of the present application, the ceramic layer 102 has a grammage of 0.8-1.2 g / m 2 . It has been found that when the ceramic layer 102 has a grammage of 0.8-1.2 g / m 2 , the waterproof and moisture-permeable layer 100 maintains good air and moisture permeability and bonding strength, and the grammage of the ceramic layer 102 is not excessively large, thereby avoiding an increase in the weight of the shell fabric. For example, the ceramic layer 102 can have a grammage of 0.8 g / m 2 , 0.9 g / m 2 , 1.0 g / m 2 , 1.1 g / m 2 , 1.2 g / m 2 , or a range defined by any two of the above values.

[0069] In some embodiments of the present application, the ceramic layer 102 has a thickness of 0.5-3 μm. If the thickness of the ceramic layer 102 is too small, the particle size of the ceramic particles required is too small, which easily blocks the pore structure of the microporous membrane 101, and if the thickness is too large, the shell fabric has an increased grammage, and the peeling strength between the layers is reduced. For example, the ceramic layer 102 can have a thickness of 0.5 μm, 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, or a range defined by any two of the above values.

[0070] In some embodiments of the present application, the ceramic particles in the ceramic layer 102 have a particle size D50 of 0.2-1 μm. The type of ceramic particles is not particularly limited in the present application, and the ceramic particles can be selected from ceramic particles commonly used in the art, including but not limited to one or more of alumina, boehmite, or zirconia. If the particle size D50 of the ceramic particles is too small, the ceramic particles easily enter the micropores of the microporous membrane and block the micropores, thereby reducing the air and moisture permeability of the shell fabric of the storm coat. If the particle size D50 of the ceramic particles is too large, it is not conducive to forming a ceramic layer 102 with a small thickness, and the shell fabric of the storm coat has a more obvious increase in weight, which is not conducive to the portability of the shell fabric. For example, the particle size D50 of the ceramic particles can be 0.2 μm, 0.4 μm, 0.6 μm, 0.8 μm, 1.0 μm, or a range defined by any two of the above values.

[0071] In some embodiments of the present application, the polyvinyl alcohol layer 103 has a grammage of 1-8 g / m 2By controlling the gram weight of the polyvinyl alcohol layer 103 within the above range, the fabric can have a lower weight while maintaining good waterproof performance. For example, the gram weight of the polyvinyl alcohol layer 103 can be 1 g / m 2 , 2 g / m 2 , 3 g / m 2 , 4 g / m 2 , 5 g / m 2 , 6 g / m 2 , 7 g / m 2 , 8 g / m 2 , or a range defined by any two of the above values.

[0072] In some embodiments of the present application, the polyvinyl alcohol layer 103 can be made of polyvinyl alcohol with a molecular weight of ≥80W. High molecular weight polyvinyl alcohol also makes the molecular chain longer, increases the degree of entanglement between molecules, hinders the contact between water molecules and hydroxyl groups, and the strong hydrogen bonding between the hydroxyl groups in the molecule itself can reduce its hydrophilicity, so that the polyvinyl alcohol layer 103 maintains good waterproof performance.

[0073] In some embodiments of the present application, the thickness of the polyvinyl alcohol layer 103 is 0.1-3 μm. If the thickness of the polyvinyl alcohol layer is too small, it is difficult to effectively play a waterproof role, and if the thickness is too large, it will lead to a decrease in air and moisture permeability and an increase in fabric weight. For example, the thickness of the polyvinyl alcohol layer 103 can be 0.1 μm, 0.2 μm, 0.3 μm, 0.4 μm, 0.5 μm, 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, or a range defined by any two of the above values.

[0074] By adjusting the thickness, gram weight, pore size, material, and other parameters of the microporous membrane 101, ceramic layer 102, and polyvinyl alcohol layer 103, the waterproof and moisture-permeable layer 100 can have a gram weight of 3-11 g / m 2 , a hydrostatic pressure of >20 KPa, and a moisture permeability of >10000 g / (m 2 ·24h). Within the above numerical ranges, the shell fabric has a lower weight, better waterproof performance, and air and moisture permeability. For example, the gram weight of the waterproof and moisture-permeable layer 100 can be 3 g / m 2 , 4 g / m 2 , 6 g / m 2 , 8 g / m 2 , 10 g / m 2 , 11 g / m 2 , or a range defined by any two of the above values. In the present application, the hydrostatic pressure is measured according to GB / T4744, and the moisture permeability is measured according to GB / T12704.2.

[0075] In some embodiments of the present application, the nylon fabric layer 110 is connected to the waterproof and moisture-permeable layer 100 through a first glue layer (not shown in the figure), and the first glue layer includes a plurality of first glue points, and the total area of the plurality of first glue points is not greater than 38% of the surface area of the waterproof and moisture-permeable layer 100. The arrangement of the plurality of first glue points can be set as needed, for example, the plurality of first glue points are arranged in a matrix. Preferably, the plurality of first glue points are arranged in multiple rows and multiple columns. The spacing between adjacent first glue points in each row or each column is equal.

[0076] It should be noted that the plurality of the above refers to the total area of all the first glue points being not greater than 38% of the surface area of the waterproof and moisture-permeable layer 100.

[0077] In some embodiments of the present application, the nylon Kortri layer 120 is connected to the waterproof and moisture-permeable layer 100 through a second glue layer (not shown in the figure), and the second glue layer includes a plurality of second glue points, and the total area of the plurality of second glue points is not greater than 50% of the surface area of the nylon Kortri layer 120. The arrangement of the plurality of second glue points can be set as needed, for example, the plurality of second glue points are arranged in a matrix. Preferably, the plurality of second glue points are arranged in multiple rows and multiple columns. The spacing between adjacent second glue points in each row or each column is equal.

[0078] It should be noted that the plurality of the above refers to the total area of all the second glue points being not greater than 50% of the surface area of the nylon Kortri layer 120.

The initial hydrostatic pressure of the shell fabric is not less than 70 KPa, and the hydrostatic pressure after washing is not less than 47 KPa. Both the initial hydrostatic pressure and the hydrostatic pressure after washing are much higher than those of the traditional shell fabric, and the shell fabric has excellent washing resistance. The water vapor permeability of the shell fabric is not less than 13000 g / (m 2 ·24h), and the shell fabric has excellent waterproof and moisture permeability. Compared with example 2, when the nylon Kortri fabric layer is attached to the surface of the polyvinyl alcohol layer in example 1, the initial hydrostatic pressure, the hydrostatic pressure after washing, and the water vapor permeability of the shell fabric are relatively more excellent.

[0125] 2) Compared with example 1, the weight of the shell fabric is obviously increased after the waterproof and moisture permeable layer of polytetrafluoroethylene film in comparative example 1, and the initial hydrostatic pressure, the hydrostatic pressure after washing, and the water vapor permeability of the shell fabric are all poor.

[0126] 3) Compared with example 1, when only the polypropylene microporous film is used as the waterproof and moisture permeable layer in comparative example 2, the weight of the shell fabric is low, but the initial hydrostatic pressure, the hydrostatic pressure after washing, and the water vapor permeability of the shell fabric are all poor.

[0127] 4) Compared with comparative example 2, when the polyvinyl alcohol layer is set on the microporous film as a whole as the waterproof and moisture permeable layer in comparative example 3, the shell fabric can maintain a low weight, but the initial hydrostatic pressure, the hydrostatic pressure after washing, and the water vapor permeability are all poor compared with example 1, and the waterproofness, washing resistance, and moisture permeability of the shell fabric still need to be improved.
