Method of forming and shaping waterproof and moisture permeable shoe upper and shoe upper thereof
A method of forming and shaping a waterproof and moisture permeable shoe upper includes disposing a shoe upper and a waterproof and moisture permeable film on a shoe last, wherein at least one of the shoe upper and the waterproof and moisture permeable film includes microwave treatable material, and heating the shoe last with the shoe upper and the waterproof and moisture permeable film thereon by microwave, so that the shoe upper and the waterproof and moisture permeable film are combined by the microwave treatable material and shaped to form the waterproof and moisture permeable shoe upper after cooling.
1. A method of forming and shaping a waterproof and moisture permeable shoe upper, comprising:
disposing a shoe upper and a waterproof and moisture permeable film on a shoe last, wherein at least one of the shoe upper and the waterproof and moisture permeable film comprises microwave treatable material; and
heating the shoe last with the shoe upper and the waterproof and moisture permeable film thereon by microwave, so that the shoe upper and the waterproof and moisture permeable film are combined by the microwave treatable material and shaped to form the waterproof and moisture permeable shoe upper after cooling,
wherein the shoe upper is a dual-layered knitted structure comprising an inner layer and an outer layer, and the method further comprises:
disposing a plurality of second semi-foamed granules comprising microwave treatable material between the inner layer and the outer layer before the heating step,
wherein during the heating step, the second semi-foamed granules are foamed to form an insole bonded to the waterproof and moisture permeable shoe upper.
2. The method of claim 1 , wherein the waterproof and moisture permeable film is disposed between the shoe last and the shoe upper.
3. The method of claim 1 , wherein the waterproof and moisture permeable film is disposed between the inner layer and the outer layer.
4. The method of claim 1 , before the heating step, further comprising:
disposing a plurality of first semi-foamed granules comprising microwave treatable material into a mold; and
disposing the shoe last with the shoe upper and the waterproof and moisture permeable film thereon on the mold in a manner that the shoe upper at least partially contacts the first semi-foamed granules,
wherein during the heating step, the first semi-foamed granules are foamed to form an outsole bonded to the waterproof and moisture permeable shoe upper.
5. The method of claim 4 , further comprising:
disposing an auxiliary element in the mold, wherein during the heating step, the plurality of first semi-foamed granules are foamed and pressed against each other to hold the auxiliary element, so that the auxiliary element is embedded in the outsole.
6. The method of claim 4 , wherein the plurality of first semi-foamed granules comprises a plurality of first granules within a first range of grain size and a plurality of second granules within a second range of grain size; a median of the first range of grain size is substantially larger than a median of the second range of grain size, and the step of disposing the plurality of first semi-foamed granules comprises disposing the plurality of first granules and the plurality of second granules in different regions of the mold.
7. The method of claim 4 , wherein the step of disposing the plurality of first semi-foamed granules further comprises:
disposing one or more film-like members in the mold to contact the plurality of first semi-foamed granules.
8. The method of claim 7 , wherein at least one of the film-like members has a pattern, and the outsole has an indication pattern corresponding to the pattern.
9. The method of claim 4 , wherein the microwave treatable materials of the at least one of the shoe upper and the waterproof and moisture permeable film, the first semi-foamed granules, and the second semi-foamed granules are same or different material, and independently selected from the group consisting of polyurethane, thermoplastic polyurethane, thermoplastic elastomer, and a combination thereof.
10. A waterproof and moisture permeable shoe upper made by the method of claim 1 , characterized in that:
the waterproof and moisture permeable film has a waterproof ability of 1000 mm to 2000 mm or more and a moisture permeability of 2000 to 3000 g/m 2 /24 h or more.
11. A method of forming and shaping a waterproof and moisture permeable shoe upper, comprising:
disposing a shoe upper and a waterproof and moisture permeable film on a shoe last, wherein at least one of the shoe upper and the waterproof and moisture permeable film comprises microwave treatable material;
disposing a plurality of first semi-foamed granules comprising microwave treatable material into a mold;
disposing the shoe last with the shoe upper and the waterproof and moisture permeable film thereon on the mold in a manner that the shoe upper at least partially contacts the first semi-foamed granules, and
heating the shoe last with the shoe upper and the waterproof and moisture permeable film thereon by microwave, so that the shoe upper and the waterproof and moisture permeable film are combined by the microwave treatable material and shaped to form the waterproof and moisture permeable shoe upper after cooling,
wherein during the heating step, the first semi-foamed granules are foamed to form an outsole bonded to the waterproof and moisture permeable shoe upper.
