Description

Technical Field

[0001] The utility model relates to the field of composite materials, in particular to a waterproof composite fabric. Background Art

[0002] Waterproof fabrics used in people's lives are becoming more and more widespread, such as raincoats, but because they are made of plastic, they are not breathable and feel uncomfortable. Now, polyester material adhesive substrate layers (such as polyester materials or waterproof fabrics such as plastics) are generally used to increase the comfort of body feeling. However, the existing polyester waterproof fabrics generally have the disadvantages of low strength, easy to get dirty, and poor skin touch. For example, bed sheets, quilts, quilt covers, pillow covers, etc. used in hospitals have high frequency of use, long continuous use time, and high probability of contact with dirt. If the polyester waterproof fabrics in the prior art are used, on the one hand, the hygiene requirements are high due to the use of patients, and on the other hand, they need to be frequently cleaned and replaced due to the use environment. Because of their poor strength, their service life is not long and they are easy to break. Moreover, their skin touch is poor compared to traditional cotton products, and patients feel poor; in addition, the waterproof effect of the waterproof composite polyester fabrics in the prior art is also not ideal. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the utility model provides a waterproof composite fabric, which solves the defects of the existing waterproof polyester composite fabric, such as being easy to get dirty, having a short service life, having a poor skin touch, and having an unsatisfactory waterproof effect.

[0005] (II) Technical solution

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A waterproof composite fabric, comprising a fabric layer made of polyester material, characterized in that: it also comprises a base material layer made of polyester material, the upper surface of the base material layer and the lower surface of the fabric layer are respectively bonded to a film layer through a glue layer, the fabric layer and the base material layer are both made of polyester fiber, and the weight percentage of the polyester fiber used in the fabric layer and the base material layer is 1:0.15-0.35;

[0008] The upper surface of the fabric layer is covered with cilia made of polyester material.

[0009] Adding a film layer can effectively enhance the strength of the fabric; the fabric layer and the base material layer are made of polyester fibers in the aforementioned weight percentage, which can more effectively achieve the effects of waterproofing, breathability, and good body feel; on the one hand, the cilia can increase the waterproof effect, and on the other hand, because they are thinner and softer than the polyester fibers that constitute the fabric layer, they can improve the user's skin touch, and can also effectively block dust and stains, so that dust and stains are gathered in the cilia layer and separated from the fabric layer, which is easy to clean.

[0010] Furthermore, a waterproof layer is provided on the upper surface of the fabric layer, and the cilia penetrate the waterproof layer and extend upwards to the fabric layer. Adding a waterproof layer can further enhance the waterproof effect.

[0011] The aforementioned film is made of thermoplastic polyurethane elastomer rubber material (TPU). This material is breathable on the one hand and can improve the strength of the composite fabric on the other hand.

[0012] The aforementioned glue layer material is polyurethane (PU). The glue layer of this material is breathable.

[0013] The aforementioned waterproof layer includes one of PTFE, polyurethane (PU), and TPU. These materials all have air permeability and moisture permeability.

[0014] (III) Beneficial effects

[0015] The waterproof composite fabric made by the above-mentioned technical scheme or technical measures has the effects of being waterproof, anti-fouling, high-strength, long service life and high user comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a structural schematic diagram of a specific implementation mode 1 of the utility model;

[0017] Figure 2 It is a structural schematic diagram of a specific implementation method of the utility model;

[0018] In the figure: 1 is the base material layer, 2 is the fabric layer, 3 is the glue layer, 4 is the film layer, 5 is the waterproof layer, and 6 is the cilia. DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings to clearly and completely describe the technical solution of the utility model. Obviously, the described implementation is only a part of the utility model, not all of it. Based on the implementation in the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Implementation method 1: Please refer to Figure 1 .

[0021] The waterproof composite fabric comprises a fabric layer 2 and a base material layer 1 made of polyester fiber, the upper surface of the base material layer 1 and the lower surface of the fabric layer 2 are respectively bonded to a film layer 4 through a glue layer 3, the fabric layer and the base material layer are both made of polyester fiber, and the weight percentage of the polyester fiber used in the fabric layer 2 and the base material layer 1 is 1:0.15;

[0022] The upper surface of the fabric layer 2 is covered with cilia 6 made of finer polyester fibers.

[0023] The film layer 4 is made of thermoplastic polyurethane elastomer rubber material (TPU). The film layer 4 can be made by weaving the above-mentioned materials in the form of fibers or in the form of plates.

[0024] The glue layer is made of polyurethane, which has good air permeability. Of course, because its properties are similar to those of the film layer material, it also has a good bonding effect.

[0025] Implementation method 2: See Figure 2 .

[0026] The difference between this embodiment and the first embodiment is:

[0027] The upper surface of the fabric layer is also coated with a waterproof layer 5 , and the cilia 6 penetrate the waterproof layer 5 and extend toward the upper side of the fabric layer 2 .

[0028] The waterproof layer 5 can be one of PTFE, PU, ​​and TPU. These materials can form a microporous membrane, which can pass air and micro-droplets (humid air), but cannot pass droplets such as sweat, blood, water droplets, etc.

[0029] In addition, in this embodiment, the weight percentage of polyester fiber used in the fabric layer 2 and the base material layer 1 is 1:0.35. The ratio of the two fibers represents the amount used in the waterproof composite fabric per unit area, and the appropriate ratio is selected according to the needs. The polyester fiber used in the fabric layer is thinner than that in the base material layer, so the cost (price) is higher. If it is used more, the cost is high, but the waterproof, breathable and body comfort effects are better. At the same time, it can support denser and longer cilia to improve the dust and dirt prevention effect; on the contrary, if the proportion of fibers used in the base material layer is increased, the cost will be reduced, but the effect will also be reduced.
