Description

Moisture permeable waterproof shoes

The present invention relates to a shoe, and more particularly to a moisture permeable waterproof shoe.

At present, shoes are developed into a mature technical field and there are many types, such as casual shoes, sports shoes, long and short boots, etc. Among them, the uppers are made of fabric casual shoes, sports shoes and long and short boots, etc. The advantage is that the sweat moisture emitted from the foot can be effectively discharged outward, and the disadvantage is that the external moisture cannot be prevented from infiltrating.

For example, when a user wears golf shoes or tennis shoes for a ball game, the breathable cloth upper can effectively remove sweat moisture for comfortable wear, but exercise the environment on a heavier morning, or step on the wet. In the grass, the cloth upper is easy to adhere to the moisture in the air or the water droplets condensed on the grass. After a long time, the cloth upper will be soaked and the water will infiltrate.

Therefore, when a user wears the above-mentioned shoe upper using the cloth upper, a water repellent agent is sprayed on the outer surface of the upper to achieve a certain degree of waterproof and antifouling effect, but the above waterproofing method is limited to use. On the upper surface of the fabric with dense pores and low water pressure resistance, it can not effectively resist the high rain pressure or the high water pressure of stepping on the water inlet. In addition, the water-repellent agent sprayed on the outer surface of the upper is easy to be rubbed against the external environment, so the user needs to frequently make up the water-repellent agent to maintain the waterproof and anti-fouling effect of the upper. It is quite inconvenient.

Therefore, the purpose of the present invention is to provide a moisture-permeable waterproof shoe that can achieve a moisture-permeable waterproof effect on a full upper.

Thus, the novel moisture permeable waterproof shoe comprises an upper, at least one waterproof trim, and a sole.

The upper is sewn from a plurality of upper cut pieces, and the upper cut piece is formed by a moisture-permeable waterproof cloth having an inner lining cloth, an outer base cloth, and a connecting body The moisture permeable waterproof membrane between the inner lining and the outer base fabric, the inner lining of the upper cut pieces cooperate to define a wearing space for the one foot to penetrate.

The waterproof trim strip is made of thermoplastic polyurethane and is fixed to the outer surface of the outer base fabric of the upper by a high-frequency thermocompression bonding method and covers the seam of the upper.

The sole is affixed to the outer bottom of the upper.

The effect of the novel is that the moisture-permeable waterproofing membrane of the upper and the waterproof decorative strip covering the seam of the upper are matched, so that the new moisture-permeable waterproofing shoe can achieve the function of moisture permeability and waterproofness of the whole upper. . Furthermore, the moisture permeable waterproofing membrane of the moisture-permeable waterproof shoe is sandwiched between the outer base fabric and the inner lining cloth, thereby avoiding the occurrence of wear and tear due to contact friction with the outside, so that the upper can Maintain long-lasting waterproof and moisture permeable effect.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figure 1, an embodiment of the present moisture permeable waterproof footwear includes an upper 5, at least one waterproof trim 6, and a sole 8.

The upper 5 is made by the following steps:

Referring to FIG. 2, an outer base fabric 1 and an inner lining 2 are provided. The outer base fabric 1 has a top surface 11 and a bottom surface 12 which are oppositely disposed. The inner lining cloth 2 has a top surface 21 and a bottom surface 22 which are oppositely disposed. Next, referring to FIG. 3, a moisture-permeable waterproof resin is coated on the bottom surface 12 of the outer base fabric 1 to form a coating layer 3, and then the outer base fabric 1 and the coating layer 3 are placed in an oven (not shown). The coating 3 is heated and dried to form a moisture-permeable waterproof film 30 at a heating temperature and for a heating time, and the thickness of the moisture-permeable waterproof film 30 after drying and curing is between 10 μm and 50 μm. In the present embodiment, the moisture permeable waterproof resin is a polyurethane (PU) resin, but is not limited thereto. The heating temperature and the heating time may be adjusted depending on the type of the moisture-permeable waterproof resin and the thickness of the moisture-permeable waterproof film 30, and are each in the range of 50 ° C to 180 ° C and 1 minute to 5 minutes.

Referring to FIG. 4, the top surface 21 of the inner lining 2 is then adhered to the surface of the outer moisture-absorbing waterproof film 30 opposite to the outer base fabric 1 by an adhesive, and the moisture-permeable waterproof film 30 is attached to the outer base fabric. 1 and the inner lining 2, the outer base fabric 1, the inner lining cloth 2, and the moisture permeable waterproof film 30 are a moisture permeable waterproof fabric 4.

Referring to FIG. 5, after the moisture-permeable waterproof fabric 4 is cut out of the plurality of upper panels 41, referring to FIG. 6, the upper panels 41 are sewn into the upper 5, and the inner lining of the upper 5 2 defines a wearing space 50 that can be inserted into the set.

Referring to FIG. 7, the waterproof decorative strip 6 is made of thermoplastic polyurethane, and the waterproof decorative strip 6 is fixed to the outer surface of the outer base fabric 1 of the upper 5 by high-frequency thermocompression bonding and covers the outer surface. The seam 51 of the upper 5 is. Thereby, the waterproof trim strip 6 can be used to prevent water from entering the wearing space 50 from the seam 51 of the upper 5 in addition to the aesthetic decorative function. In the present embodiment, the waterproof molding strip 6 extends on the outer surface of the outer base fabric 1 of the upper 5 to form a pattern.

Referring to FIG. 1 , the sole 6 is attached to the outer bottom of the upper 3 by means of an adhesive 4 .

In the present embodiment, the moisture permeable waterproof film 30 of the moisture permeable waterproof fabric 4 has a water repellency measured under the waterproof standard test method of Japanese JIS L1092B, which is a hydrostatic pressure of more than 3000 mm water column height, and in the day. The moisture permeability measured under the moisture permeability standard test method of JIS L1099B1 is more than 3000 g/m ² /24 hr.

It is worth mentioning that when the outer base fabric 1 is made of a fabric having a large gap between the threads such as a breathable mesh cloth, the bottom surface 12 of the outer base fabric 1 is not easily attached to form the moisture-permeable waterproof film 30, so The moisture permeable waterproof film 30 is formed on the top surface 21 of the inner lining 2 which is denser between the woven threads, and then the bottom surface 12 of the outer base fabric 1 is attached to the moisture permeable waterproof film 30 opposite to the The surface of the inner lining 2 is such that the moisture-permeable waterproof film 30 is connected between the outer base fabric 1 and the inner lining 2 to obtain the moisture-permeable waterproof fabric 4. Preferably, the moisture permeable waterproof film 30 is formed in a manner not limited to the above-mentioned coating film forming method, and a commercially available functional film having moisture permeable, waterproof and air permeable properties may be directly attached to the outer base fabric 1 The top surface 12 is formed to form the moisture permeable waterproof film 30.

It is further worth mentioning that the moisture permeable waterproof fabric 4 can also be water-repellent on the top surface 11 of the outer base fabric 1 so that the prepared moisture-permeable waterproof shoe 9 can prevent water from penetrating to a certain extent. The effect of the outer base fabric 1 of the upper 5 is achieved to achieve a better waterproof effect.

In summary, the novel moisture permeable waterproof shoe has the following advantages and advantages, so it can achieve the purpose of the present invention:
