The windproof and breathable layer 400 is composed of 50-100% of TPU mixed glue, the air permeability of the windproof and breathable layer 400 is 0.01% -25%, and the air permeability of the embodiment is 0.3%. The wind-proof and air-permeable layer 400 is a dot structure with gaps, and the gaps of the wind-proof and air-permeable layer 400 are uniformly arranged.

The bonding layer 200 is a dot structure, and the bonding layer 200 is PA thermosol or TPU thermosol.

The elastic lock velvet layer 300 is of a cobweb-shaped structure, and the raw material of the elastic lock velvet layer 300 is elastic resin.

The surface layer fabric 600 includes: the surface layer structure 610, the link yarn 620 and the bottom layer napping structure 630 are sequentially connected from top to bottom, and the bottom layer napping structure 630 is a gap structure.

The mixture material of the TPU mixed glue of the windproof and breathable layer 400 is PA powder.

The utility model discloses an innovation point: firstly, the improvement of the windproof layer is realized, the traditional windproof layer is formed by heating TPU powder, then pouring the heated TPU powder onto a roller, and then coating a layer on the surface of the fabric to form a film-shaped structure, so that the fabric forms a film which has complete connectivity and no gap, and can completely block the air circulation between the interior of the fabric and the outside, thereby achieving the windproof and warm-keeping effects. But such structure will let whole surface fabric lose tension and elasticity, and because airtight, aqueous vapor can't exchange, and sweat lock is died at the surface fabric inlayer, and the comfort level reduces by a wide margin. 100% of TPU powder or at least 50% of a mixture of TPU powder and PA powder is used in the material. The method comprises the steps of prefabricating raw materials of a windproof and breathable layer into a dissolving solution by adopting a 3D printing technology, spraying the semi-fluid prefabricated dissolving solution on an elastic flocking layer by using a spray head of a 3D printer, forming dot structures in a spraying mode, arranging the dot structures uniformly with gaps, and forming a compact TPU film-like structure after light moisture is gradually evaporated in a subsequent heating process. The structure has gaps, which means that the structure has air permeability, the air permeability is adjusted by adjusting the proportion of the formula, and the air permeability is controlled to be 0.3% in the embodiment, so that sweat can be discharged outwards, the heat dissipation effect is realized, and the amount of cold air entering is controlled to be in a small range. Meanwhile, as the structure is not like the traditional complete membranous structure, the extensibility and the elasticity of the structure are well ensured.

Secondly, the concept of adding a hollow breathable layer. The structure of the hollow layer is not available on the traditional fabric. Or an additional hollow structure is added in the fabric. The hollow structure has connection relation from top to bottom and from left to right. Resulting in loss of tetrahedral elasticity during stretching.

The utility model discloses a ventilative layer of cavity is the unique structure of one deck that forms after the surface fabric is accomplished, and its essence is a joint structure of constituteing by the bottom napping structure 630 of initial elasticity lock fine hair layer 300, prevent wind ventilative layer 400 and eiderdown layer 500 and top layer surface fabric 600.

The middle three layers of this structure are actually in a "bulk" state. The left side and the right side are not connected, and the upper side and the lower side are vertically connected through fibers, so that the requirement of four-side elasticity can be met in the stretching process.

The void value of the hollow layer 700 is 0.1mm to 10mm, and in this embodiment, the void value is controlled to 3 mm. If the void value exceeds the maximum range, the hollow layer 700 is excessively thick, so that the entire fabric is difficult to bend and the feeling is very stiff. If the thickness is less than the minimum value, the thickness is too thin, and the heat insulating effect of the hollow layer is reduced, which affects the heat insulating property.

The above description has been made of the embodiments of the present invention, but the present invention is not limited thereto, and various changes may be made without departing from the spirit of the present invention.
