Description

an elastic fabric

technical field

The utility model relates to the technical field of textile fabrics, in particular to an elastic fabric.

Background technique

Fabric is the material used to make clothing. Fabric can not only interpret the style and characteristics of clothing, but also directly affect the color, shape and other performance effects of clothing. In order to ensure the tensile strength, the existing elastic fabrics generally have high density, resulting in comfortable It lacks in durability, and at the same time, it needs to be strengthened in terms of warmth retention, waterproof and breathability.

Utility model content

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide an elastic fabric with a simple structure, good heat retention, waterproof and air permeability.

In order to achieve the above purpose, the technical solution of the utility model is: an elastic fabric, including a thermal insulation layer in the middle, elastic layers are provided on both sides of the thermal insulation layer, and the two elastic layers are opposite to the side where the thermal insulation layer is located. The other side is provided with a waterproof and breathable layer, the thermal layer is woven through warp and weft yarns twisted from cotton fibers and wool fibers, the elastic layer is interwoven with warp yarns and weft yarns, and the warp yarns are ten Polyester with a zigzag cross section, the weft yarn is covered with spandex, and the elastic layer is provided with a plurality of through holes running through its upper and lower surfaces.

The waterproof and breathable layer is TPU film or ePTFE film.

The beneficial effects of the utility model are: simple structure, high strength, good elasticity, good warmth retention, waterproof and air permeability.

In the figure: thermal insulation layer 1, elastic layer 2, waterproof breathable layer 3, through hole 4.

detailed description

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of elastic fabric, comprises the thermal insulation layer 1 in the middle, the both sides of described thermal insulation layer 1 are all provided with elastic layer 2, on the two elastic layers 2 opposite to the side where thermal insulation layer 1 is located Both sides are provided with a waterproof and breathable layer 3, that is, the elastic fabric of the present invention includes a waterproof and breathable layer 3, an elastic layer 2, a thermal layer 1, an elastic layer 2 and a waterproof and breathable layer 3 arranged sequentially from outside to inside.

The thermal insulation layer 1 is formed by warp and weft knitting of yarns twisted from cotton fibers and wool fibers. Cotton fibers have good moisture absorption and air permeability, and are soft and warm; wool fibers are deformed products of sheep skin and have excellent warmth retention properties; The thermal insulation layer 1 made of cotton fiber and wool fiber has very good thermal insulation effect.

The elastic layer 2 is formed by interweaving warp yarns and weft yarns, the warp yarns are polyester with a cross-section, the weft yarns are spandex-covered yarns, and the elastic layer 2 is provided with a plurality of through holes 4 running through its upper and lower surfaces , the polyester warp yarn adopts special-shaped cross-section, which has good hygroscopicity and excellent elasticity; the spandex covered yarn uses spandex filament as the core, and the stretched spandex filament is treated by filament or short fiber yarn in a spiral manner. The elastic yarn formed by covering, spandex is a kind of elastic fiber, which is highly elastic and can be stretched 6 to 7 times, but can quickly return to its original state as the tension disappears. In the utility model, nylon can be used to cover the spandex yarn. Nylon has excellent wear resistance and strength, and at the same time, the elastic recovery rate can reach 100%, and it can withstand tens of thousands of times of bending without breaking. The through holes 4 can improve the air permeability of the elastic layer 2 and at the same time improve the elasticity of the elastic layer 2 to a certain extent.

The waterproof and breathable layer 3 is a TPU film or an ePTFE film. The TPU film and the ePTFE film have good elasticity and high strength. In addition to high waterproof performance, they also have excellent moisture permeability, that is, water cannot pass through and human sweat can freely penetrate. .

The elastic fabric of the utility model is designed with internal and external symmetry, that is, the front and back sides can be used interchangeably, which greatly enhances the practicability.

The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto, and any person familiar with the technical field can easily think of it within the technical scope disclosed by the utility model Changes or replacements should fall within the protection scope of the present utility model.
