Description

Technical Field

[0001] The utility model relates to the technical field of water-repellent fabrics, in particular to a composite fabric. Background Art

[0002] Fabric is the material used to make fabrics. Fabric is woven from threads. Due to the interlaced weaving of threads, there will be gaps between the threads of the fabric, which leads to poor waterproof effect of the fabric alone. Now, in order to make the fabric have a certain degree of waterproofness, a water-repellent layer is often set on the surface of the fabric.

[0003] Because the waterproof layer has a layer of ultra-fine "needle bed" attached to the surface of the fabric, the surface tension of the fabric is less than the cohesive force of water. Therefore, water droplets will form water droplets and roll away (like lotus leaves repelling water). However, the inventors found in daily life that the "needle bed" formed by the water-repellent layer will be flattened by rain when it rains heavily (that is, when the impact of rain is greater), and the water-repellent function of the fabric will be greatly reduced, or even begin to absorb water. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a water-repellent composite fabric.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a water-repellent composite fabric, including a cloth body, the cloth body including two layers of base cloth, the two layers of base cloth are stacked together, the two layers of base cloth are sewn together with a stitching line, a water-repellent layer is arranged on the upper end of the base cloth located at the bottom, and a water-repellent layer is arranged on the upper end of the base cloth located at the top, the stitching line passes through the surface of the upper base cloth from bottom to top to set the water-repellent layer, which can prevent water from seeping from the stitching line to the lower base cloth, and the stitching line passes through the surface of the lower base cloth from top to bottom to set the water-repellent layer, which can prevent water from passing through the stitching line through the lower base cloth.

[0006] The effect achieved by the above components is that: the surfaces of the two layers of base fabrics are both provided with a water-repellent layer. Even if the outer base fabric is impacted by rain and its hydrophobicity is reduced, the bottom base fabric still has the water-repellent layer in effect (and the lower base fabric has the upper base fabric to buffer the water flow and reduce the impact of the water flow, thus avoiding the "needle bed"-shaped water-repellent layer from being flattened as much as possible), thereby improving the water-repellent property of the entire fabric.

[0007] Preferably, the suture line sews the two layers of base fabric into one, and divides the surface of the base fabric into a number of rectangular areas.

[0008] The effects achieved by the above components are as follows: the two layers of base fabrics are connected and fixed together by the stitching lines, and the areas on the surface of the base fabrics separated by the stitching lines reduce the friction between the base fabrics as much as possible.

[0009] Preferably, a padding cloth is bonded to the upper end of the lower base cloth, the padding cloth is placed between the two layers of base cloth, and the sewing line passes through the lower base cloth, the padding cloth and the upper base cloth.

[0010] The effect achieved by the above components is that the padding cloth pads the gap between the two layers of base cloth to further prevent the water-repellent layer from being flattened due to friction between the two layers of base cloth.

[0011] Preferably, the base fabric is woven by interlacing warp and weft threads.

[0012] The effect achieved by the above components is that the warp and weft weaving between the warp and weft lines has stronger physical properties.

[0013] Preferably, the warp threads are composed of cotton threads and antibacterial threads interlaced with each other, and the weft threads are composed of cotton threads and antibacterial threads interlaced with each other.

[0014] The effects achieved by the above components are: cotton silk can provide better breathability and fit, antibacterial silk can reduce overall bacterial growth, and the warp and weft weaving between the two can ensure that the fabric has the advantages of both to a certain extent.

[0015] Preferably, the antibacterial silk comprises flax fiber and metal antibacterial fiber, wherein the metal antibacterial fiber is interlaced and woven on the surface of the flax fiber to form the silk.

[0016] The effects achieved by the above components are: flax fiber is used as the skeleton of antibacterial silk, wherein flax fiber contains a large amount of phenolic substances such as flavonoids, steroids, tannins, etc., which can inhibit the growth of bacteria; metal antibacterial fiber is made by pressing metal powder into thin film silk and compounding it with other fibers; or directly using metal single substance to blend with other fibers; or metal or its compound particles are produced by blending antibacterial fiber. The main antibacterial mechanism of metal antibacterial fiber is: after a small part of metal ions are slightly dissolved in humid air, they have very high biological activity, are easy to combine with other substances, and can destroy the physiological process of bacteria (since metal antibacterial fiber is an existing conventional technical means, it will not be explained in detail).

[0017] Preferably, the suture thread comprises two cotton threads, and the two cotton threads are twisted into a thread.

[0018] Preferably, a core wire is embedded inside the cotton thread.

[0019] The effect achieved by the above components is: the two ends of the two core wires can be connected to the buzzer module power input line and the battery power output line respectively. When the cotton thread is soaked, the two core wires are connected to the battery to power the buzzer to alarm, thereby achieving the effect of prompting that the waterproofness of the upper base cloth is reduced.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] In the utility model, the surfaces of the two layers of base fabrics are both provided with a water-repellent layer. Even if the outer base fabric is impacted by rain and its hydrophobicity is reduced, the bottom base fabric still has the water-repellent layer to take effect (and the lower base fabric has the upper base fabric to buffer the water flow and reduce the impact of the water flow, thus avoiding the "needle bed"-shaped water-repellent layer from being flattened as much as possible), thereby improving the water-repellent property of the entire fabric.
