The invention relates to a method for manufacturing a shoe, in particular to a method for manufacturing a moisture-permeable waterproof shoe.

At present, shoes are a mature and mature technology field, such as casual shoes, sports shoes, long and short boots, and rain boots. Among them, casual shoes, sports shoes and long and short shoes with fabric, textile or natural leather. The advantage of the boots and the like in wearing is that the sweat moisture emitted from the feet can be effectively discharged outward, and the disadvantage is that the external moisture cannot be prevented from infiltrating.

However, the use of synthetic leather casual shoes, sports shoes and long and short boots, etc., is advantageous in that it can effectively prevent external water from infiltrating, and conversely, the disadvantage is that the sweat that is applied by using the upper foot cannot be worn. It is effectively discharged, so that the feeling of wearing the foot is quite sultry and uncomfortable. Moreover, it is necessary to apply a waterproof strip or a waterproof glue on the seam of the upper for waterproof treatment, so that the synthetic leather shoe can achieve comprehensive waterproofing. The effect, but in this way, because the synthetic leather itself has a certain weight, the setting of the waterproof strip or the waterproof glue increases the overall weight of the footwear, and causes great load on the user's foot in wearing. .

The synthetic leather footwear has the advantages of being moisture permeable and eliminating the need to provide a waterproof strip or waterproof glue at the seam of the upper. Compared with the existing rubber rain boots, it has the advantage of moisture permeability. Moreover, the present invention is to cut the substrate. After sewing the upper, the existing rain boots are integrally molded by the mold, which can not only eliminate the development of the mold, but also can be obtained by cutting the substrate into different shapes of the upper pieces. Moisture-permeable waterproof shoes of different shoe types, such as casual shoes, sports shoes, and long and short boots.

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.

An embodiment of the method for producing a moisture permeable waterproof shoe of the present invention comprises the following steps:

Referring to Figures 1 and 2, step (A) 100: providing a substrate 11. The substrate 11 has an outer base fabric 111, a foam layer 112 and an inner lining 113 which are attached and fixed together. The foam layer 112 is connected between the outer base fabric 111 and the inner lining 113. Referring to FIG. 3, after the substrate 11 is cut into a plurality of upper panels 12, referring to FIG. 4, the upper panels 12 are sewn into an upper 1. The inner lining 113 of the upper 1 defines a piercing space 10 through which a foot can be inserted.

Referring to FIG. 1 and FIG. 5, step (B) 200: inserting a shoe last 2 into the wearing space 10 disposed on the upper 1 to fix the appearance of the upper 1 to prevent the upper 1 from being deformed by external force. Next, referring to FIG. 6, the upper 1 is impregnated into a moisture-permeable waterproof resin tank 3, and is subjected to an impregnation time so that the moisture-permeable waterproof resin 31 in the moisture-permeable waterproof resin tank 3 is attached to the upper 1 The outer base fabric 111 surface and covers the seam 13 of the upper 1.

Two kinds of non-porous membranes. The porous film has a plurality of micropores whose openings are much smaller than the volume of the water droplets, so that the penetration of moisture can be blocked, thereby achieving the waterproof effect. However, the openings of the micropores are much larger than the water vapor molecules, allowing the water vapor to pass through. In order to achieve the effect of moisture permeability. The non-porous film itself does not have micropores and can achieve water-repellent effect. However, the moisture permeability of the non-porous film is absorbed by water vapor through a hydrophilic functional group on one side thereof, and is diffused to the other side by capillary phenomenon. The hydrophobic functional group is then convected by air to remove moisture.

In the present embodiment, the moisture permeability of the moisture permeable waterproofing membrane 32 measured under the waterproof standard test method of Japanese JIS L1092B is a hydrostatic pressure of more than 2000 mm water column height, and a moisture permeability standard of the Japanese standard JIS L1099B1.

Referring to FIG. 12 , a pattern 115 is printed on the surface of the outer substrate 111 opposite to the inner lining 113 of the substrate 11 , and the material of the moisture permeable waterproof film 32 is made of a transparent material. Moisture-permeable waterproof shoes can be more diverse in appearance.

More specifically, the moisture permeable waterproof resin 31 may be mixed with at least one of an additive such as a pigment, an ultraviolet absorber, and an antibacterial agent, so that the moisture permeable waterproof film 32 formed on the upper 1 may have a corresponding The efficacy of the above additives, such as color enhancement, UV resistance, antibacterial and the like.

In addition, it is worth mentioning that the structural design of the substrate 11 through the foam layer 112 enables the moisture-permeable waterproof shoe made by the invention to achieve soft and comfortable wearing under light weight, and of course The other design requirements of the moisture permeable waterproof shoe omits the foam layer 112, and a substrate 11 having only one outer base fabric 111 and one inner lining 113 fixed together. Preferably, the substrate 11 can also be natural leather.

In summary, the method for producing the moisture permeable waterproof shoe of the present invention has the following advantages and advantages, and thus the object of the present invention can be achieved:

1. By immersing the upper 1 in the moisture permeable waterproof resin tank 3, the surface of the outer base fabric 111 of the upper 1 and the seam 13 of the upper 1 can be completely covered to form the moisture permeability. The waterproof membrane 32, so that the prepared moisture-permeable waterproof shoes can achieve the function of moisture permeability and waterproofness of the whole upper, that is, the moisture-permeable waterproof shoes are waterproof and waterproof compared with the existing fabrics, textiles or natural leather footwear. The advantage is that compared with the existing synthetic leather footwear, it has the advantages of moisture permeability and no need to provide a waterproof strip or waterproof glue at the seam of the upper, and has the advantage of moisture permeability compared with the existing rubber rain boots.

Second, the substrate 11 is a three-layer structure using the outer base fabric 111, the foam layer 112 and the inner lining 113. Compared with the synthetic leather upper and the rubber upper, the weight can be effectively reduced greatly, and The obtained moisture-permeable waterproof shoes can achieve soft and comfortable wearing under light weight.

3. The present invention is to cut the substrate 11 and then sew it into the upper 1. Compared with the prior art, the rain boots are integrally molded by the mold, which not only eliminates the development of the mold, but also cuts the substrate 11 By cutting out different shapes of the upper piece 12, it is possible to obtain moisture-permeable waterproof shoes of different shoe types, such as casual shoes, sports shoes, and long and short boots.

The moisture-permeable waterproof shoe prepared by the present invention can be surface-treated by forming a cortical texture 114 or a pattern 115 on the surface of the outer base fabric 111 of the substrate 11 opposite to the inner lining 113, and then cooperating with the moisture permeability.
