Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the present invention provides a textile with a coating layer, comprising a first substrate 1 and a second substrate 2 both made of air-permeable material, wherein a gap interlayer through which air can flow freely is formed between the first substrate 1 and the second substrate 2 by a plurality of protrusions, a waterproof coating 3 is disposed on one side of the first substrate 1 close to the gap interlayer, and all sides of the gap interlayer are sealed; or at least one end of the gap interlayer is communicated with the atmosphere.
When this fabrics was as the waterproof overcoat in spring and autumn, it need it to have better air permeability and waterproof performance, can be sealed with clearance intermediate layer upper and left and right sides this moment, use its lower side of structure such as zip fastener open, then the clearance intermediate layer can communicate with the external world to a certain extent, but because its open angle and area for the clearance intermediate layer can not excessively breathe freely and arouse catching a cold.
When the textile is used as a winter warm-keeping coat, the textile is required to have higher warm-keeping performance, so that the periphery of the gap interlayer can be sealed. After the periphery of the gap interlayer is sealed, a large amount of air can be stored between the first base material 1 and the second base material 2 due to the effect of the gap interlayer, so that the heat-insulating property of the textile is improved to a certain extent.
Preferably, the waterproof coating 3 is a non-porous covering mastic layer or a non-porous covering mastic layer with a pore size of less than 100 μm.
Due to the function of the gap interlayer, the second base material 2 in contact with the human body has no coating, the skin layer of the human body can be directly ventilated with the gap interlayer through the second base material 2, and the gap interlayer can be communicated with the outside so as to further improve the ventilation performance of the fabric.
Preferably, the plurality of projections comprises a plurality of structures one 4 and a plurality of structures two 5; the size of the first structure 4 along the width direction of the gap interlayer is larger than that of the first structure 4 along the width direction of the gap interlayer; the lower edge of the first structure 4 and the lower edge of the second structure 5 are arranged on one side, close to the gap interlayer, of the second substrate 2 in a flush mode; the upper edge of the first structure 4 and the upper edge of the second structure 5 are arranged in a staggered mode, and one side, close to the gap interlayer, of the second substrate 2 is attached to the upper edge of the first structure 4 and the upper edge of the second structure 5, so that wrinkles are formed on the second substrate 2. The first structure 4 and the second structure 5 are both point-shaped bulges or strip-shaped bulges.
Through the height dislocation of the first 4 and the second 5 upper surfaces of the structure for form the fold on the second 2 substrate, the fold is used for providing a certain buffer space for the waterproof coating 3 and avoiding the damage caused by excessive pulling.
The first structure 4 and the second structure 5 may be bumps or ribs made of polyurethane with certain elasticity, and compared with the conventional structure, the overall weight of the structure can be reduced by using the bumps, but the connection stability is poor, and the overall weight can be increased by using the ribs, but the overall connection stability can be increased.
The first structure 4 and the second structure 5 can also be formed of fiber strips of different thicknesses, since the fiber strips have good air permeability but do not significantly affect the overall softness of the textile. The fiber strips with higher density have slightly poor air permeability, but the strength of the fiber strips is improved, so that the clearance interlayer can be better supported; and the material of the fiber strips also influences the overall strength and air permeability of the fiber strips. For example, chemical fibers, which are effective in increasing the lifespan of the product, natural fibers (cotton, etc.), which are somewhat shorter because they are easily rotten, degraded, etc.
Further, if the structures of the first structure 4 and the second structure 5 are changed, that is, some hollow structures are designed in the polyurethane bumps or the raised strips, the fiber strips can be made to take some specific shapes, such as a rolling area shape, and the air permeability of the first structure 4 and the second structure 5 can be enhanced to a certain degree.
