Abstract

An improved waterproof breathable fabric is characterized in that a breathable bottom layer is provided with a plurality of first breathable pores, wherein each first breathable pore is of an inverted U shape, a transitional isolation layer is arranged on the breathable bottom layer, a main body of the transitional isolation layer is of a corrugated shape, each downward bent part of the transitional isolation layer is fixedly connected with the surface of the breathable bottom layer, a first isolation chamber is formed between each upward-depressed part of the transitional isolation layer and the breathable bottom layer, an elastic bar is arranged inside each first isolation chamber, the transitional isolation layer is also provided with a plurality of inverted U-shaped second breathable pores, a waterproof surface layer is arranged on the transitional isolation layer, each upward-bent part of the transitional isolation part is fixedly connected with the bottom surface of the waterproof surface layer, and a second isolation chamber is formed between each downward-depress part and the waterproof surface layer, an elastic bar is arranged inside the second isolation chamber, and the waterproof surface layer is also provided with a plurality of inverted U-shaped third breathable pores. The improved waterproof breathable fabric has the characteristics of good elasticity, good breathability and stronger floating force.

Description

A kind of modified waterproof and breathable fabric

Technical field

The utility model belongs to the textile clothing fabric and makes the field, relates to a kind of modified waterproof and breathable fabric.

Background technology

Continuous upgrading along with manufacturing technology, new functional fiber cloth is satisfying the growing demand of people gradually, replaced gradually natural fiber, chemical fibre is through being endowed more function after the modification, thereby for the textile industry new product development and cater to consumer demand sound assurance is provided.Diving and swimming all are the motions that people like, but owing to the fabric problem of some diving dress or swimsuit causes dress to get up to feel too tight and airtight, so bring some inconvenience for the people of scuba diver or swimming, and the water resistance of existing these fabrics is not fine, so moisture content can infiltrate, so also can cause certain inconvenience.

The utility model patent technical measures of 2009201394838 " a kind of Novel waterproof ventilate surface material " patent No. are disclosed before are, this fabric can exist the buoyancy of fabric strong not in the middle of reality is used after being processed into product, transition separation layer in the middle of the fabric is extruded distortion under the pressure of water, finally also cause the gas permeability of fabric to reduce.

Summary of the invention

In order to remedy above-mentioned existing deficiency, the utility model provides a kind of modified waterproof and breathable fabric, it can effectively prevent transition separation layer in the middle of the fabric under hydraulic pressure by excessive compression, and in the situation that does not affect permeability, effectively increase the buoyancy of fabric, the characteristics that it has good springiness, does not affect permeability, waterproof effect is good, buoyancy is stronger.

In order to achieve the above object, the utility model adopts following concrete technical scheme: a kind of modified waterproof and breathable fabric, it is by ventilative bottom, the transition separation layer, elastic strip, waterproof layer forms, its architectural feature is, ventilative bottom is provided with a plurality of first ventilative lumen pore, each first ventilative lumen pore is inverted U-shaped, the transition separation layer is arranged on the ventilative bottom, the body of transition separation layer is wavy fluctuating, the reclinate part of transition separation layer is fixedly connected with the surface of ventilative bottom, upwards form the first isolated chamber between the part of depression and the ventilative bottom, the first isolated chamber is built-in with elastic strip, the transition separation layer also is provided with a plurality of inverted U-shaped second ventilative lumen pore, waterproof layer is arranged on the transition separation layer, and the part that the transition separation layer is bent upwards is fixedly connected with the bottom surface of waterproof layer, forms the second isolated chamber between the part of lower recess and the waterproof layer, the second isolated chamber is built-in with elastic strip, and waterproof layer also is provided with a plurality of the inverted U-shaped the 3rd ventilative lumen pore.

The first isolated chamber, the second isolated chamber and elastic strip play the effect that increases buoyancy.Ventilative bottom, transition separation layer, elastic strip and waterproof layer all adopt the hotness material of good springiness to make, when hotness material after heated, its ventilative lumen pore can open, the gas that the human body pore is discharged and suitably thermal release in isolated chamber, finally be discharged in the external environment condition by the ventilative lumen pore in the waterproof layer, and hydrone can't enter in the transition separation layer by the ventilative lumen pore from waterproof layer.The elastic strip after heated also can expand, and makes the first isolated chamber and the second isolated chamber remain with all the time certain space under hydraulic pressure, thereby guarantees the permeability of fabric.

The beneficial effects of the utility model are, it has good springiness, permeability is good, buoyancy is stronger characteristics.

The utility model is described in further detail below in conjunction with drawings and Examples.

Description of drawings

Fig. 1 is the local tangent plane structural representation of the utility model.

The specific embodiment

As shown in Figure 1, a kind of modified waterproof and breathable fabric, it comprises ventilative bottom 1, transition separation layer 2, elastic strip A, waterproof layer 3, it is characterized in that, ventilative bottom 1 is provided with a plurality of first ventilative lumen pore 11, each first ventilative lumen pore 11 is inverted U-shaped, transition separation layer 2 is arranged on the ventilative bottom 1, the body of transition separation layer 2 is wavy fluctuating, transition separation layer 2 reclinate parts are fixedly connected with the surface of ventilative bottom, upwards form the first isolated chamber between the part of depression and the ventilative bottom 1, the first isolated chamber is built-in with elastic strip A, transition separation layer 2 also is provided with a plurality of inverted U-shaped second ventilative lumen pore, waterproof layer 3 is arranged on the transition separation layer 2, and the part that transition separation layer 2 is bent upwards is fixedly connected with the bottom surface of waterproof layer 3, forms the second isolated chamber between the part of lower recess and the waterproof layer 3, the second isolated chamber is built-in with elastic strip A, and waterproof layer 3 also is provided with a plurality of the inverted U-shaped the 3rd ventilative lumen pore.
