Waterproof anti-ultraviolet fabric

Abstract

The waterproof and anti-ultraviolet fabric comprises a full-dull polyester fabric layer, a waterproof breathable film, a hollow fabric layer and a chinlon fabric layer which are sequentially arranged, the full-dull polyester fabric layer is formed by interweaving full-dull cotton-like polyester composite filaments serving as warps and wefts, and the full-dull cotton-like polyester composite filaments comprise full-dull polyester POY filaments and full-dull polyester FDY filaments which are arranged in parallel and connected through network points. The full-dull polyester fabric layer formed by interweaving the full-dull cotton-like polyester filaments has a good anti-ultraviolet effect due to the fact that a delustering agent titanium dioxide is added into the full-dull polyester filaments, and the titanium dioxide also has a good anti-ultraviolet effect. Meanwhile, the hollow polyester fiber yarns and the Viloft fiber yarns are interwoven to form a warm-keeping fabric layer. The waterproof breathable film enables the fabric to have a good waterproof effect.

[0002] With the progress of the times and the continuous development of science and technology, in order to meet the wearing needs of modern people, many types and styles of textile fabrics have emerged and become the main consumer products of modern people. Especially in the plateau areas, the temperature is relatively low in spring and autumn, and the ultraviolet intensity is relatively high. When the temperature is low, the fabric is required to have good heat preservation effect to resist the invasion of cold air. Especially in rainy weather, the heat loss of the human body is more serious and the body temperature drops faster. How to prepare a waterproof and ultraviolet-proof fabric has become a problem to be solved. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waterproof and ultraviolet-proof fabric, which has the effects of waterproof and breathable and ultraviolet-proof.

[0010] On the basis of the above scheme and as the preferred scheme of the above scheme: a moisture-absorbing and heat-generating fabric layer is arranged between the hollow fabric layer and the nylon fabric layer.

[0011] The beneficial effects of the present utility model are as follows: A waterproof and ultraviolet-proof fabric related to the present utility model, the fully dull polyester fabric layer made of fully dull cotton-like polyester filaments interwoven has good ultraviolet resistance. This is because titanium dioxide, a dulling agent, is added to the fully dull polyester filaments, and titanium dioxide also has good ultraviolet-proof effect. At the same time, a warm-keeping fabric layer is formed by interweaving hollow polyester fiber yarns and Viloft fiber yarns. The waterproof and breathable membrane makes the fabric have good waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is a schematic structural diagram of the waterproof and ultraviolet-proof fabric according to the first embodiment;

[0013] Figure 2 is a schematic structural diagram of the waterproof and ultraviolet-proof fabric according to the second embodiment.

[0014] The markings in the figure are explained as follows: 1 - fully dull polyester fabric layer; 2 - waterproof and breathable membrane; 3 - hollow fabric layer; 4 - polyamide fabric layer; 5 - moisture-absorbing and heat-generating fabric layer. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] First Embodiment

[0017] Combined with Figure 1 , this embodiment will be described in detail. A waterproof and ultraviolet-proof fabric related to this embodiment includes a fully dull polyester fabric layer 1, a waterproof and breathable membrane 2, a hollow fabric layer 3, and a polyamide fabric layer 4 arranged in sequence; specifically, each layer is compounded through a hot melt adhesive web.

[0018] The fully dull polyester fabric layer 1 is interwoven with fully dull cotton-like polyester composite filaments. The fully dull cotton-like polyester composite filaments include fully dull polyester POY filaments and fully dull polyester FDY filaments arranged in parallel and connected by network points. The number of networks is 30 - 50 per meter, and in this embodiment, it is 40 per meter. The specifications of both the fully dull polyester POY filaments and the fully dull polyester FDY filaments are 192 dtex / 108f. The network points are formed by the high-speed air ejected from the network nozzles entangling the fully dull polyester POY filaments and the fully dull polyester FDY filaments.

[0019] The hollow fabric layer 3 is formed by interweaving hollow polyester fiber yarns and Viloft fiber yarns. Viloft fiber is a new type of wood pulp cellulose fiber produced by Acordis Company, meeting the requirements of eco-friendly imitation. Its cross-section is uniquely flat, with a flatness greater than 5:1. Through the capillary effect formed by the fine grooves and holes on the fiber surface, the moisture and sweat on the skin surface can be discharged to the outside through functions such as wicking, diffusion, and transmission, enabling the skin to breathe freely. Viloft fiber has good warmth retention and comfort. When blended with other fibers with circular cross-sections, it can form unique moisture-conducting channels in the yarn body, showing excellent wicking and moisture-regulating functions. Viloft fiber has good strength, elasticity, warmth retention, anti-static performance, as well as good blending and dyeing properties. The hollow polyester fiber yarn only has a good warmth retention effect.

[0020] Furthermore, the polyamide fabric layer 4 is woven from graphene-modified polyamide filaments. Specifically, the fineness of the antibacterial polyamide filaments is 72D / 75F.

[0021] Furthermore, the waterproof and breathable membrane 2 is an ePTFE membrane. In this embodiment, it is selected as an ePTFE membrane. Since the PTFE material is used, on the premise of having a good waterproof and moisture-permeable effect, it can also improve the good anti-ultraviolet effect.

[0022] Embodiment 2

[0023] Combined with Figure 2 , a detailed description of this embodiment is given. The difference between a waterproof and anti-ultraviolet fabric involved in this embodiment and that in Embodiment 1 is that a moisture-absorbing and heat-generating fabric layer 5 is provided between the hollow fabric layer 3 and the polyamide fabric layer 4.

It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art should fall within the protection scope determined by the claims.
