The invention provides a waterproof fabric, which comprises a waterproof polyester layer, a double-sided TPU waterproof breathable film and a PET high stretch yarn layer, wherein the waterproof polyester layer is positioned on an outer layer and is woven by waterproof polyester yarns with an anti-siphon effect; the double-sided TPU waterproof breathable film comprises a core layer, a first TPU waterproof breathable film arranged on the outer side face of the core layer, and a second TPU waterproof breathable film arranged on the inner side face of the core layer.

The waterproof fabric has the advantages of multilayer structure, novel and reasonable structural design, strong waterproof performance, strong moisture permeability and air permeability, high comfort level, capability of meeting multiple requirements, capability of resisting various weather and environments, wide application range, firmness and firmness, and simple processing technology.

Drawings

Fig. 1 is an exploded structural schematic view of an embodiment of a waterproof fabric of the present invention.

The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, an embodiment of the waterproof fabric of the present invention is provided, which includes a waterproof polyester layer 101 woven by waterproof polyester yarns with anti-siphon effect on an outer layer, a double-sided TPU waterproof breathable film disposed on an inner side surface of the waterproof polyester layer 101, and a PET high stretch yarn layer 102 woven by PET high stretch yarns disposed on an inner side surface of the double-sided TPU waterproof breathable film, wherein the waterproof polyester layer 101 and the double-sided TPU waterproof breathable film, and the double-sided TPU waterproof breathable film and the PET high stretch yarn layer 102 are bonded by hot pressing, so that the fabric is firm and stable, and the processing process is simple. The double-sided TPU waterproof breathable film comprises a core layer 103, a first TPU waterproof breathable film 104 arranged on the outer side face of the core layer 103, and a second TPU waterproof breathable film 105 arranged on the inner side face of the core layer 103. The proportion of the three raw materials of the waterproof polyester yarn, the PET high stretch yarn and the double-sided TPU waterproof breathable film can be adjusted according to the weaving requirement of the fabric. The waterproof polyester yarn is prepared by crystallizing and processing the polyester yarn, and can achieve the effect of preventing water splashing.

Along with the improvement of everybody quality of life, people's travelling comfort and functional requirement to the clothes surface fabric of dress are higher and higher, if the demand to the waterproof function of surface fabric is higher and higher, the structure tradition of ordinary waterproof surface fabric on the existing market is old, the performance is more single, only can prevent the infiltration of rainwater, but be unfavorable for breathing freely, can make people feel sultry, the comfort level is general, make the surface fabric be difficult to satisfy multiple demand, application scope receives very big restriction, and, current waterproof surface fabric generally directly uses the yarn that has the characteristic of preventing the splash water to weave into single-layer structure, water-proof effects is not good enough, can't reach higher waterproof grade, waterproof ability can't be applicable to various weather and environment, be difficult to effectively resist and extremely abominable weather. And this waterproof surface fabric's structural design is novel reasonable, has multilayer structure, is waterproof dacron layer 101, the waterproof ventilated membrane of two-sided TPU, PET high stretch yarn layer 102 respectively, and wherein, waterproof dacron layer 101 has waterproof dacronThe double-sided TPU waterproof breathable film comprises a core layer 103, a first TPU waterproof breathable film 104 arranged on the outer side face of the core layer 103, and a second TPU waterproof breathable film 105 arranged on the inner side face of the core layer 103. The TPU waterproof breathable film has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance and the like, and simultaneously has a plurality of excellent functions of high waterproofness, moisture permeability, wind resistance, cold resistance, antibiosis, mildew resistance, warm keeping, ultraviolet resistance, energy release and the like. It is worth noting that the TPU waterproof breathable film has very strong waterproof performance, and simultaneously the high air permeability can reach 10000g/m ²24 hours, even after the thermal compression bonding, the temperature can reach 5000-²The TPU waterproof breathable film has excellent moisture permeability and breathability except for high waterproof performance, sweat of a human body can freely penetrate through the TPU waterproof breathable film, the human body does not feel sultry, the comfort level is high, multiple requirements are met, various weathers and environments can be resisted, and the application range is wide. And the double TPU waterproof breathable films are arranged in the waterproof fabric, so that the waterproof and breathable performance is greatly improved. In this waterproof fabric, waterproof polyester layer 101, dual TPU waterproof ventilated membrane have ensured waterproof performance, make this surface fabric can reach the highest waterproof grade, in addition, dual TPU waterproof ventilated membrane has ensured the moisture permeability gas permeability ability. In addition, in the waterproof fabric, the waterproof polyester layer 101 and the double-sided TPU waterproof breathable film and the PET high stretch yarn layer 102 are connected in a hot pressing mode, so that the fabric is firm and stable, and the processing technology is simple.

The waterproof fabric has the advantages of multilayer structure, novel and reasonable structural design, strong waterproof performance, strong moisture permeability and air permeability, high comfort level, capability of meeting multiple requirements, capability of resisting various weather and environments, wide application range, firmness and firmness, and simple processing technology.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, are included in the scope of the present invention.
