The technical field is as follows:
the utility model relates to the field of fabrics, in particular to a breathable waterproof fabric.
Background art:
conventional water sports garments are basically made of waterproof fabrics, mainly natural or synthetic fabrics, which are waterproofed by laminating or coating elastic waterproof materials composed of, for example, polyvinyl chloride, styrene-butadiene, silicone, polyurethane or latex. However, clothes coated with such waterproof materials are uncomfortable to wear, and sweat of a human body is hardly evaporated through such materials. With the technological progress, researchers have developed microporous-free integral membranes, such as TPU or polytetrafluoroethylene waterproof breathable films, which allow rapid diffusion of water vapor but do not allow liquid water to pass through the membrane, provide a waterproof effect by coating the inner surface of the fabric with a waterproof breathable film, and provide mechanical protection to the membrane surface, and since all waterproof breathable films are very thin and delicate, they are usually combined with fabrics with higher mechanical strength, which are usually composed of wear-resistant fabrics, such as polyester, polypropylene or nylon woven fibers, and usually, these fabrics are not stretchable, resulting in the production of water sports clothes which are breathable but bulky, inconvenient to stretch during sports and have poor wearing comfort.
The utility model has the following contents:
the utility model aims to solve the technical problem of providing the breathable waterproof fabric which is good in breathability and convenient to stretch, and the breathable waterproof fabric is suitable for being used as water sports clothes.
The utility model provides a breathable waterproof fabric, which comprises a fabric body, wherein the fabric body is formed by sequentially compounding a first waterproof breathable base material layer, a breathable layer and a second waterproof breathable base material layer from top to bottom, the first waterproof breathable base material layer and the second waterproof breathable base material layer are both formed by compounding a stretchable fabric layer on the outer surface and a waterproof breathable film on the inner surface, the breathable layer is a closed-cell polymer foam layer, and a plurality of breathable holes are formed in the breathable layer in a penetrating manner along the upper surface and the lower surface.
Compared with the prior art, the utility model has the following advantages after adopting the structure: through set up ventilative layer between waterproof ventilative substrate layer and the waterproof ventilative substrate layer of second, can improve better ventilation effect, simultaneously, but the extensibility that fabric layer can improve the surface fabric is adopted to first waterproof ventilative substrate layer and the waterproof ventilative substrate layer of second, and ventilative layer adopts the obturator polymer foam layer, is favorable to waterproofly to make this surface fabric be applicable to the water sports clothing and use.
Preferably, the stretchable fabric layer is an elastic yarn fabric or a plain weave fabric formed by blending spandex and nylon. The two fabrics have good tensile property and are breathable. Wherein, the proportion of nylon and spandex can be set to 80% and 20% to provide better wearing comfort.
Preferably, the waterproof breathable film is a TPU breathable waterproof film. The breathable waterproof film has good stretching, breathable and waterproof performances, and the thickness of the breathable waterproof film can be selected from 10-35 mu m.
Preferably, the air-permeable layer is a closed cell polyvinyl chloride foam or a closed cell neoprene foam. The closed-cell polyvinyl chloride foam has sufficient stretchability and tensile strength and can be directly adhered to a TPU breathable waterproof film through an adhesive, or the closed-cell chloroprene rubber foam is selected, so that the closed-cell polyvinyl chloride foam also has high stretchability, and the closed-cell foam provides certain floating performance when the surface layer or the inner layer of the fabric or the finished product thereof, such as water sports clothes, is torn or broken, so that the closed-cell polyvinyl chloride foam is safer, and the water immersion of the whole foam layer is limited to the breathable holes. The open-cell foam, when saturated, submerges the entire foam layer and reduces the safety of the foam structure when used in water sports apparel. The thickness of the foam layer may be selected to be 3-6mm, based on a combination of safety and wearing comfort.
Furthermore, the area occupied by the air holes accounts for 25-50% of the surface area of the air-permeable layer. This has better breathability and reduces the weight of the breathable layer.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a sectional view a-a of fig. 1.
The specific implementation mode is as follows:
the utility model is further described with reference to the following figures and detailed description:
as shown in fig. 1 and 2, a breathable waterproof fabric comprises a fabric body, wherein the fabric body is formed by sequentially compounding a first waterproof breathable substrate layer 1, a breathable layer 2 and a second waterproof breathable substrate layer 3 from top to bottom, the first waterproof breathable substrate layer 1 and the second waterproof breathable substrate layer 3 are formed by compounding a stretchable fabric layer 10 on the outer surface and a waterproof breathable film 11 on the inner surface, the breathable layer 2 is a closed-cell polymer foam layer, and the breathable layer 2 is provided with a plurality of breathable holes 21 along the upper surface and the lower surface in a penetrating manner.
The stretchable fabric layer 10 is a plain weave fabric formed by weaving 20% of spandex and 80% of nylon in a mixed manner. The fabric has good tensile property and is breathable so as to provide better wearing comfort. The waterproof breathable film 11 is a TPU breathable waterproof film. The stretchable fabric layer is adhered to the TPU breathable waterproof film through an adhesive, and the thickness of the TPU breathable waterproof film is preferably 15 mu m.
Meanwhile, the air-permeable layer 2 has a density of 15kg/m3The ultra-light closed-cell PVC (polyvinyl chloride) foam has enough stretchability and tensile strength, can be directly bonded to a TPU breathable waterproof film through an adhesive, and has a thickness of about 4 mm. In an alternative embodiment, a density of 110kg/m may also be used3The closed cell neoprene foam of (1). Both foams have high tensile properties. Also, the foam is selected to have a closed cell structure, which provides greater safety due to better flotation properties when the outer substrate layer is cracked or torn. When the open-cell foam is soaked in water, the open-cell foam can be soaked into the whole foam, so that the influence on the water sports clothes is caused.
Considering the ventilation requirement and reducing the weight of the ventilation layer, the area of the ventilation holes is about 35 percent of the surface area of the ventilation layer, so that the weight can be effectively reduced while the ventilation property is considered, and the good floatability is kept.
In a further embodiment, the breathable layer 2 is laminated with the substrate layers on both sides by means of an adhesive, during the lamination process, the breathable layer is pre-stretched to some extent, for example, 5%, and after the breathable layer 2 is bonded to the first waterproof breathable substrate layer 1 and the second waterproof breathable substrate layer 3 by means of the adhesive, the breathable layer maintains tension and helps to form indentations as shown in fig. 2, and the first waterproof breathable substrate layer 1 and the second waterproof breathable substrate layer 3 maintain a contracted state. Specifically, the first waterproof and breathable substrate layer 1 and the second waterproof and breathable substrate layer 3 are bonded to the two sides of the breathable layer 2 by polyurethane adhesives by using a hot press or a heating roller, and the adhesive can form firm bonding between the breathable layer 2 and the TPU breathable and waterproof film at the temperature without damaging the integrity of the TPU breathable and waterproof film. This process will cause the first and second waterproof, breathable substrate layers 1, 3 to contract in the machine direction by about 2-3%, which reduces the surface area of the stretchable fabric layer 10 by about 2-3%, which creates an inward depression that provides a dimpled texture 31 formed on the shaped vent that enhances the aesthetic appearance of the garment surface and also has the effect of creating an air gap between the user's skin and the proximal surface of the garment. This is, of course, not absolutely necessary.
The utility model discloses a set up ventilative layer between waterproof ventilative substrate layer and the waterproof ventilative substrate layer of second, can improve better ventilation effect, simultaneously, but the extensibility that fabric layer can improve the surface fabric can be adopted to first waterproof ventilative substrate layer and the waterproof ventilative substrate layer of second, and ventilative layer adopts obturator polymer foam layer, is favorable to waterproofly, especially when the outer or inlayer of clothing on water breaks into water, can provide the security. The fabric is suitable for water sports clothes.
