Description

High-performance waterproof breathable safety shoe

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of waterproof safety shoes, especially, relate to a waterproof ventilative safety shoes of high performance.

[ background of the invention ]

The general waterproof safety shoes can prevent liquid from entering the safety shoes within a certain time, and the sole and the upper of the safety shoes are separated and glued into a whole. The waterproof safety shoe can prevent water from entering the safety shoe, but is easy to degum, and can not effectively prevent water from gradually permeating into the safety shoe, so that the waterproof time and effect are limited. The protective effect cannot be completely met for some working environments which require long-time feet to be sunk in water. In the prior art, some waterproof shoes are provided with soles and uppers which are integrated but airtight, and are easy to sweat due to airtightness after being worn for a long time, so that extremely uncomfortable feeling is caused.

Therefore, there is a need to provide a new high performance waterproof breathable safety shoe to solve the above problems.

[ Utility model ] content

A primary object of the utility model is to provide a waterproof ventilative safety shoes of high performance, sole and instep part adopt integrative injection moulding, cooperate the waterproof ventilative layer of high performance, have improved waterproof performance and air permeability greatly, have improved wearer's comfort.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a waterproof ventilative safety shoes of high performance, its whole cross-section is from interior to exterior includes ventilative layer, waterproof layer and vamp layer in proper order, safety shoes include sole portion, vamp portion, upper of a shoe portion from bottom to top in proper order, sole portion with vamp portion corresponds the vamp layer is a layer vamp is moulded plastics to integrative injection moulding's PU.

Furthermore, the vamp layer corresponding to the upper part is a leather vamp.

Furthermore, the leather vamp is sewn and connected with the PU injection molding layer vamp through a connecting part to form a whole vamp layer.

Further, the waterproof layer is a waterproof polyester film.

Further, the breathable layer is a microporous foamed polypropylene layer or a microporous breathable PU layer.

Compared with the prior art, the utility model relates to a waterproof ventilative safety shoes of high performance's beneficial effect lies in: the vamp of the safety shoe is divided into two parts, one part is the vamp part with the shoe bottom part corresponding to the vamp part, the integrated vamp is formed by integrated injection molding, no glue seam and no seam are arranged between the vamp part and the shoe bottom part, the comprehensive waterproof effect below the upper is realized, and the problems of degumming and water leakage are avoided; the other part is an upper part, and the vamp of the upper part is made of leather; and a layer of high-performance waterproof layer is pasted on the surface of the inner wall of the vamp layer, so that double waterproof performance and waterproof permeation are achieved, and the breathable layer is combined, so that the breathability and the comfort of the safety are greatly improved.

[ description of the drawings ]

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic cross-sectional structure of the present invention;

the figures in the drawings represent:

100 high performance waterproof breathable safety shoe texture structures;

1, a breathable layer; 2, waterproof layer; 3, a shoe upper layer; 4 shoe bottom; 5, shoe upper parts; 6 an upper part; 7 upper part of shoe.

[ detailed description ] embodiments

Example (b):

referring to fig. 1-2, the present embodiment is a high-performance waterproof and breathable safety shoe 100, which includes a breathable layer 1, a waterproof layer 2 and a shoe upper layer 3 in sequence from inside to outside in the overall cross section, the safety shoe 100 includes a shoe bottom 4, a shoe upper 5 and a shoe upper 6 in sequence from bottom to top, and the shoe bottom 4 and the shoe upper layer 3 corresponding to the shoe upper 5 are an integrally injection-molded PU injection-molded upper.

The vamp layer 3 that upper of a shoe portion 6 corresponds is the leather vamp, and through a connecting portion 7 with PU moulds plastics a layer vamp and sews up and link together, forms whole vamp layer 3.

The waterproof layer 2 is a waterproof polyester film.

The air-permeable layer 1 is a microporous foamed polypropylene layer or a microporous air-permeable PU layer.

According to the high-performance waterproof breathable safety shoe 100, the vamp of the safety shoe is divided into two parts, one part is the vamp part with the sole part corresponding to the vamp part, the integrated vamp is formed by adopting integrated injection molding, no adhesive seam or seam is arranged between the vamp part and the sole part, the comprehensive waterproof effect below the upper is realized, and the problem of degumming and water leakage is avoided; the other part is an upper part, and the vamp of the upper part is made of leather; and a layer of high-performance waterproof layer is pasted on the surface of the inner wall of the vamp layer, so that double waterproof performance and waterproof permeation are achieved, and the breathable layer is combined, so that the breathability and the comfort of the safety are greatly improved.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
