Description

No-stick one-piece waterproof and breathable membrane inside

This creation is a kind of “inner-free waterproof and breathable film inner lining”, which consists of a fine cloth and a waterproof and breathable film, which are adhered to each other and become a waterproof and breathable cloth. The surface of the cloth is waterproof and breathable. In response to the folding, the joining is completed in a hot-melting principle; or the waterproof and breathable cloth is taken in two pieces, and the surface layers of the waterproof and breathable film are also superposed on each other, and the joining is completed by a hot-melting principle. At the same time, it is cut into an appropriately sized foot shape to provide a waterproof shoe.

Waterproof and breathable film is a waterproof and breathable film which can be made of TPU, TPE or PTFE. The general application range is clothing and shoes. The traditional method is to use a fine cloth + waterproof breathable film + table cloth, which is made into a 3-in-1 inner lining. Then, it is cut into the shape of the desired shape, and then it is made into a three-dimensional shape by sewing the needle. Finally, it is necessary to press the waterproof strip with a high-frequency wave at the seam to prevent water leakage. The waterproof and ventilated film has a complicated inner processing process, and the waterproof function of the waterproof strip is limited. In actual use, the waterproof strip is often disengaged due to the bending movement of the shoes.

In addition, the single film is directly processed by hot-melt or high-cycle forming waterproof and breathable film. Because the waterproof and breathable film is very thin and has a little stickiness, the staff often wears a waterproof and breathable film during processing. If it is broken or broken, it will not be able to carry out the processing smoothly, which will cause difficulty in processing and time delay. The single film after molding is also easy to be broken when processing shoes, which is difficult in practical use.

Therefore, in light of the above, the creator has been engaged in the development of related products for 30 years and has developed this creation to solve the above situation.

The main purpose of this creation is to attach a fine cloth and a waterproof and breathable membrane to each other to form a waterproof and breathable cloth. The fabric is folded correspondingly with the surface layer of the waterproof and breathable membrane, or two waterproof breathable cloths are taken. The surface layers of the waterproof and breathable film are superposed one upon another, and are joined by a hot-melting principle to complete a waterproof and breathable film without sticking, and cut into an appropriately sized foot shape to provide waterproofing. Breathable footwear for use.

The secondary purpose of this creation is that the fine cloth and the waterproof and breathable membrane form an integral structure, so that when the person handles the waterproof and breathable membrane processing operation, the waterproof and breathable membrane will not stick together, causing the processing time to be delayed or impossible to work.

After the completion of the creation, the practical purpose is that the fine cloth and the waterproof and breathable membrane are combined into one body, so that the inner lining of the waterproof and breathable membrane has strong tensile strength, abrasion resistance and tear resistance, and no sticking. The hot melt method is integrally formed into a three-dimensional waterproof and breathable membrane inner lining, which makes the whole inner structure become very strong, and can withstand the long-term shoe bending activity without water seepage to achieve the practicability of the product.

Referring to the first figure, the fine cloth (12) and the waterproof gas-permeable membrane (13) are corresponding to each other, and a gas permeable adhesive (14) is applied between the two, and the fine cloth is applied by means of lamination. (12) attaching to the waterproof gas permeable membrane (13), and the gas permeable adhesive (14) enables the two to be closely attached and attached to form a waterproof and transparent Air cloth (11); since the fine cloth (12) is integrated with the waterproof gas permeable membrane (13), the waterproof structure of the waterproof gas permeable membrane (13) is resistant to abrasion and tearing, so that it is not used during use. The case of tearing or abrasion occurs; referring to the second and fourth figures, the waterproof breathable cloth (11) takes two pieces and is attached to each other with the surface of the waterproof gas permeable membrane (13), and utilizes a high A hot-dissolving principle such as Zhou Bo, ultrasonic wave, electric heating wire or vacuum forming is used to join the lining (10) of a waterproof and breathable film without sticking, and cut into an appropriately sized foot shape to provide a waterproof shoe. Please refer to the third and fourth figures. You can also use a waterproof and breathable cloth (11) to face the folded surface of the waterproof and breathable membrane (13), and a hot solution principle such as high frequency, ultrasonic, electric heating wire or vacuum forming. The method is to make a joint, complete a waterproof and breathable film inner lining (10) without stripping, and cut into an appropriately sized foot shape, thereby providing a waterproof and breathable footwear; the non-stick integrated waterproof ventilating film inner lining (10) ) not only for shoes Points, can also be applied to clothing, hats, gloves and other related products, contents of the aforementioned embodiment except that an optimal application of the present writing direction.
