In the figure: 1. the waterproof breathable fabric comprises a first waterproof breathable film, a second fabric, a first material, a second material, a hot melt adhesive, a second waterproof breathable film, a second textile fabric, a first textile fabric, a second textile fabric, a third textile fabric, and a third waterproof breathable film, wherein the first waterproof breathable film is 2, the first material is 3, the second material is 4, the hot melt adhesive is 5, the second waterproof breathable film is 6, the second textile fabric is 7.
Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
In the embodiment shown in fig. 1, a waterproof and breathable liner comprises a first material 3 and a hot melt adhesive 5, wherein the top of the first material 3 is provided with a first waterproof and breathable film 1, the bottom of the first material 3 is provided with a second material 4, and the first material 3 is fixedly connected with the first waterproof and breathable film 1 and the second material 4 through the hot melt adhesive 5. As shown in fig. 1, 2 and 3, the first material 3 is a composite material of a second waterproof breathable film 6 and a first textile fabric 7, the second waterproof breathable film 6 is located at the bottom of the first textile fabric 7, the top of the first textile fabric 7 is fixedly connected with the first waterproof breathable film 1 through a hot melt adhesive 5, and the bottom of the second waterproof breathable film 6 is fixedly connected with the second material 4 through the hot melt adhesive 5. The second material 4 is a composite material of a second textile fabric 8, a third textile fabric 9 and a third waterproof breathable film 10, the third waterproof breathable film 10 is located between the second textile fabric 8 and the third textile fabric 9, the top of the second textile fabric 8 is fixedly connected with the second waterproof breathable film 6 through a hot melt adhesive 5, the third waterproof breathable film 10 is arranged at the bottom of the second textile fabric 8, the first waterproof breathable film 1, the second waterproof breathable film 6 and the third waterproof breathable film 10 are made of the same material, and the first textile fabric 7, the second textile fabric 8 and the third textile fabric 9 are made of the same material.
The hot melt adhesive 5 at the edge of the first material 3 is distributed in a linear shape, and the hot melt adhesive 5 at the other areas except the edge of the first material 3 is distributed in a uniform dot shape. As shown in fig. 4, the hot melt adhesives 5 on the first material 3 may be distributed in a dot shape, and the distribution density of the hot melt adhesives 5 at the edge of the first material 3 is greater than that of the hot melt adhesives 5 at other areas of the first material 3 except the edge.
The principle is as follows: the material types adopted by the first waterproof breathable film 1, the second waterproof breathable film 6 and the third waterproof breathable film 10 are mainly one of PU breathable films, TPU breathable films or PTFE breathable films, and are novel high-molecular waterproof materials. Under the state of water vapor, water particles are very fine, and can smoothly permeate into the capillary to the other side according to the principle of capillary movement, so that the air permeability phenomenon is generated. After the water vapor is condensed into water drops, the particles become large, and water molecules can not smoothly break away from the water drops to permeate to the other side under the action of the surface tension of the water drops, so that the permeation of water is prevented, and the breathable film has a waterproof function. The waterproof breathable film II 6 is compounded with the textile fabric I7, and the upper surface and the lower surface of the waterproof breathable film III 10 are respectively compounded with the textile fabric II 8 and the textile fabric III 9, so that the effect of good waterproof stability is achieved. The distribution of the hot melt adhesive 5 in the area except the edge area is in dispersed point distribution, which is beneficial to the air permeability of the lining, and meanwhile, the lining adopts the fabric 2 with good air permeability, so that the whole design ensures good waterproofness and air permeability.
