Description

Technical Field

[0001] The utility model relates to a fabric, in particular to an ultraviolet-resistant, waterproof, breathable and elastic composite fabric. Background Art

[0002] With the advancement of science and technology and the improvement of economic life, people's attention to textiles is not limited to the appearance, strength, and durability of fabrics, but also to comfort and functionality. Outdoor sports, in particular, require clothing that not only protects against rain, dew, and UV rays, but also prevents sweat from condensing between the clothing and the body. However, existing fabrics fail to achieve these two functions. For example, current UV-resistant fabrics lack both waterproofness and breathability, often emphasizing one property at the expense of the other. Furthermore, current UV-resistant fabrics are not lightweight and lack the ability to respond to environmental changes.

[0003] Therefore, how to make the layers of thin and light fabrics firmly connected and at the same time have anti-ultraviolet, waterproof and moisture-permeable functions is a key point and difficulty that needs to be solved urgently. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an anti-ultraviolet waterproof breathable elastic composite fabric which has a firm connection and has the functions of anti-ultraviolet, waterproof and moisture permeability.

[0005] The utility model is realized through the following technical measures:

[0006] A UV-resistant, waterproof, breathable elastic composite fabric, characterized in that it comprises an UV-resistant coating, a waterproof surface layer, a first adhesive breathable layer, an elastic composite layer, a second adhesive breathable layer, and a skin-friendly inner layer stacked sequentially from the outside to the inside, wherein the UV-resistant coating is uniformly applied to the outer surface of the waterproof surface layer away from the skin-friendly inner layer; the elastic composite layer is attached between the waterproof surface layer and the inner layer via the first adhesive breathable layer and the second adhesive breathable layer, respectively; the elastic composite layer comprises an outer elastic layer and an inner elastic layer, and the outer elastic layer is connected to the inner elastic layer via a plurality of elastic structures.

[0007] As a preferred embodiment of the present application, the elastic structure includes an elastic protrusion provided on the inner surface of the outer elastic layer and an elastic recess provided on the outer surface of the inner elastic layer and corresponding to the position of the elastic protrusion. The elastic protrusion includes a head that matches the elastic recess and a connecting portion for connecting the head and the outer elastic layer. The surface of the head and the surface of the elastic recess are adhesive surfaces. The head is embedded in the elastic recess and is fixed by bonding the adhesive surfaces to each other.

[0008] As a preference of the present application, the head is hemispherical.

[0009] As a preference of the present application, the connecting portion is a columnar elastic body with an outer diameter smaller than an outer diameter of the head.

[0010] As a preference of the present application, moisture-permeable through holes are provided on the waterproof surface layer, the elastic composite layer and / or the skin-friendly inner layer.

[0011] As a preferred embodiment of the present application, the moisture-permeable through holes on the waterproof surface layer are tapered holes that are small on the outside and large on the inside.

[0012] As a preferred embodiment of the present invention, the density of the moisture-permeable through holes on the waterproof surface layer, the first adhesive breathable layer, the elastic composite layer, the second adhesive breathable layer, and the skin-friendly inner layer is equal or increases gradually from the outside to the inside, thereby ensuring waterproof and breathable properties while reducing the weight of the fabric.

[0013] As a preferred embodiment of the present invention, the skin-friendly inner layer is a wood pulp spunlace nonwoven fabric, an industrial wipe, or a viscose spunlace nonwoven fabric. The skin-friendly inner layer of such a material has an organic combination of good water absorption and reduced weight, thereby improving the wearing comfort of the fabric.

[0014] As a preferred embodiment of the present application, the anti-ultraviolet coating is a polyurethane film made by using micron-level film forming and positioning technology.

[0015] As a preferred embodiment of the present invention, the first and second adhesive breathable layers are EVA hot melt adhesive layers. Using EVA hot melt adhesive as the adhesive layer between the inner and outer layers achieves good adhesive strength, anti-aging and breathable properties of the first and second adhesive breathable layers.

[0016] As a preferred embodiment of the present application, an anti-tear net is attached to the inner surface of the waterproof surface layer.

[0017] As a preferred embodiment of this application, the waterproof surface layer is made of 85dtex / 72f warp and weft yarns, combined with a high-density woven base fabric layer of 560 strands / 10 cm x 380 strands / 10 cm. This effectively improves the strength of the fabric. Combined with the polyurethane film coated on the surface of the waterproof surface layer, it greatly improves the fabric's light resistance and slows down light corrosion and aging.

[0018] As a preference of the present application, both the outer elastic layer and the inner elastic layer are made of elastic cotton.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. It has high UV protection, waterproof and anti-fracture performance, and good breathability; waterproofness / Pa: ≥20000; water level reaches level 4 and above; moisture permeability / g·(m 224h) ≥3000; UPF UV protection factor: ≥30; Breaking strength (N): longitudinal ≥35, transverse ≥35; Ecological indicators: meet the national mandatory textile standard GB18401-2010;

[0021] 2. A special elastic composite layer is added between the waterproof surface layer and the skin-friendly inner layer to achieve the advantages of good adhesion, low cost, excellent elasticity, flexibility, wettability, glossiness and wear resistance of the fabric, and also has anti-ultraviolet function.

[0022] 3. The waterproof surface layer, the elastic composite layer and the skin-friendly inner layer are bonded and fixed to each other through the first bonding breathable layer and the second bonding breathable layer respectively, so that the layers are firmly connected and prevented from falling off;

[0023] 4. Each layer of the fabric is processed with various functional layers, which has the advantages of high water resistance, breathability, moisture permeability, and UV resistance. It can be used in various professional clothing, sportswear, civilian clothing, accessories, home textiles and other industries, and has a good market prospect. BRIEF DESCRIPTION OF THE DRAWINGS
