Description

Technical Field

[0001] The utility model belongs to the technical field of leather base cloth, and more specifically relates to a waterproof and breathable leather base cloth. Background Art

[0002] Artificial leather base fabric is mainly used as synthetic leather base material: after latex impregnation, coating and finishing, it becomes synthetic leather.

[0003] The existing leather base fabric, such as a composite leather base fabric disclosed in the patent document with publication number CN217073603U on July 29, 2022, is composed of a waterproof layer, an anti-ultraviolet layer, a first reinforced mesh layer, a non-woven fabric layer, a second reinforced mesh layer, an anti-static layer and a flexible layer. These fabrics cooperate with each other to obtain a composite leather base fabric with good waterproof performance; but the glass fiber woven layer and the flexible layer woven by polyurethane fiber in the anti-ultraviolet fabric layer of this leather base fabric have poor air permeability.

[0004] For traditional leather, leather with better air permeability usually has poorer waterproofness, while leather with better waterproofness usually has poorer air permeability; it is difficult to make the leather base fabric have good waterproofness and good air permeability at the same time. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a waterproof and breathable leather base fabric, which can achieve the leather base fabric having good waterproofness and good breathability.

[0006] The utility model discloses a waterproof and breathable leather base fabric, which comprises a wear-resistant layer, a waterproof and breathable layer, a base fabric layer and a hygroscopic skin-friendly layer which are fixedly connected in sequence. The wear-resistant layer is located at the outermost side, and the hygroscopic skin-friendly layer is located at the innermost side. The waterproof and breathable layer comprises a waterproof layer and a breathable layer which are arranged in sequence up and down. The bottom surface of the waterproof layer is fixedly connected to the top surface of the breathable layer. The hygroscopic skin-friendly layer comprises a hygroscopic layer and a skin-friendly layer which are arranged in sequence up and down. The bottom surface of the hygroscopic layer is fixedly connected to the top surface of the skin-friendly layer.

[0007] As a further improvement of the utility model, the wear-resistant layer is made of polyurethane acrylic resin, and air holes are provided on the surface of the wear-resistant layer.

[0008] As a further improvement of the utility model, the waterproof layer is made of thermoplastic polyurethane TPU film and natural rubber film.

[0009] As a further improvement of the present invention, the air permeable layer is made of a porous air permeable film.

[0010] As a further improvement of the present invention, the base fabric layer is made of any one of knitted fabric, woven fabric and non-woven fabric.

[0011] As a further improvement of the present invention, the moisture absorbing layer is made of viscose fiber.

[0012] As a further improvement of the utility model, the skin-friendly layer is blended by vinylon, strong fiber, polypropylene fiber and titanium dioxide anti-aging agent.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By arranging a wear-resistant layer, a waterproof and breathable layer, a base fabric layer and a moisture-absorbing and skin-friendly layer, these fabrics cooperate with each other to obtain a composite leather base fabric; wherein by arranging the wear-resistant layer, the wear resistance of the leather base fabric is improved; by arranging the waterproof and breathable layer, external water does not penetrate into the fabric under a certain pressure, while the sweat emitted by the human body can be conducted to the outside through the fabric in the form of water vapor, thereby avoiding the accumulation and condensation of sweat between the body surface and the fabric to maintain the comfort of the clothing; by arranging the moisture-absorbing and skin-friendly layer, the fabric has good moisture absorption, moisture conduction and rapid sweat discharge effects, which helps to improve the air permeability of the fabric; it can be achieved that the leather base fabric has good waterproofness and good air permeability.

[0016] Description of the numbers in the figure:

[0017] Base fabric layer 1, waterproof and breathable layer 2, wear-resistant layer 3, moisture-absorbing skin-friendly layer 4, waterproof layer 5, breathable layer 6, moisture-absorbing layer 7, and skin-friendly layer 8. DETAILED DESCRIPTION

[0018] Specific embodiment 1: Please refer to Figure 1 A waterproof and breathable leather base fabric comprises a wear-resistant layer 3, a waterproof and breathable layer 2, a base fabric layer 1 and a moisture-absorbing skin-friendly layer 4 which are fixedly connected in sequence. The wear-resistant layer 3 is located on the outermost side, and the moisture-absorbing skin-friendly layer 4 is located on the innermost side.

[0019] In this embodiment, in order to improve the wear resistance of the leather base fabric during long-term use, the wear-resistant layer 3 is made of polyurethane acrylic resin, and a silicone coating is also provided on the surface of the wear-resistant layer 3 to further improve the waterproof and breathable properties of the leather base fabric. The surface of the wear-resistant layer 3 is provided with air holes to improve the wear resistance of the leather base fabric while ensuring air permeability. This avoids the problem of rapid wear of the surface of the leather base fabric, thereby increasing the overall service life of the leather base fabric.

[0020] The waterproof and breathable layer 2 is located at the lower side of the wear-resistant layer 2. The waterproof and breathable layer 2 includes a waterproof layer 5 and a breathable layer 6 which are arranged in sequence from top to bottom. The bottom surface of the waterproof layer 5 is fixedly connected to the top surface of the breathable layer 6. The waterproof layer 5 is made of thermoplastic polyurethane TPU film and natural rubber film. The breathable layer 6 is made of porous breathable film. The thermoplastic polyurethane TPU film is located in the inner layer, and has the characteristics of waterproof, high elasticity and softness, which can effectively prevent moisture from invading the fabric. The natural rubber film is located in the surface layer, and not only has excellent resilience, insulation, water-proof and plasticity, but also has oil resistance, acid resistance, alkali resistance, wear resistance and other properties, which can protect the thermoplastic polyurethane TPU film.

[0021] By providing the waterproof and breathable layer 2, water from the outside will not penetrate into the fabric under a certain pressure, while sweat from the human body can be conducted to the outside through the fabric in the form of water vapor, thereby preventing sweat from accumulating and condensing between the body surface and the fabric to maintain the comfort of the clothing. The leather base fabric can have good waterproofness and good breathability.

[0022] The base fabric layer 1 is located at the lower side of the waterproof and breathable layer 2. The base fabric layer 1 is made of any one of knitted fabric, woven fabric and non-woven fabric.

[0023] The hygroscopic skin-friendly layer 4 is located at the lower side of the base fabric layer 1. The hygroscopic skin-friendly layer 4 includes a hygroscopic layer 7 and a skin-friendly layer 8 which are arranged in sequence from top to bottom. The bottom surface of the hygroscopic layer 7 is fixedly connected to the top surface of the skin-friendly layer 8. The hygroscopic layer 7 is made of viscose fiber. The skin-friendly layer 8 is blended with vinylon, strong fiber, polypropylene and titanium dioxide anti-aging agent. By setting the hygroscopic skin-friendly layer 4, the fabric has good moisture absorption, moisture conduction and rapid perspiration, which helps to improve the air permeability of the fabric.
