Method for making seamless waterproof and moisture-permeable shoe upper

The present invention is a method for making seamless waterproof and moisture-permeable shoe uppers, in particular to a method for forming seamless composite shoe uppers with waterproof and moisture-permeable functions that can be used to make various waterproof and moisture-permeable socks and shoes.

At present, the common integrated jointless composite shoe upper structure on the market, such as Taiwan Invention Patent No. I616149 "Method for Manufacturing Stiff Three-dimensional Socks", the method of manufacturing the stiff three-dimensional Socks includes the following Steps: (A) Preparation work: prepare a shoe last, a sole, an inner sock body, a waterproof cover, an outer sock body, and an adhesive; (B) use the shoe last to shape the operation: this step (A The inner sock body in) is sleeved into the shoe last, and then the adhesive is placed on the outer surface of the inner sock body for the first time to cover the inner sock body to initially shape the inner sock body; (C) Waterproof and appearance shaping Work: Put the waterproof cover in step (B) into the inner sock body, then set the adhesive on the outer surface of the waterproof cover for a second time, and then put the outer sock body into the waterproof cover Then, a stereo sock prototype with a shaped appearance is formed; (D) drying combined operation: the stereo sock prototype in step (C) is dried together with the shoe last, and the sock body and the inner sock body are dried together. The adhesive between the waterproof jackets will be heated and cured into a plastic bonding layer, located in the waterproof jacket The adhesive between the outer sock body and the outer sock body will be heated to solidify into a certain type of bonding layer, so that the inner sock body, the waterproof jacket and the outer sock body are tightly combined with each other in a three-in-one manner to form a defined foot A three-dimensional sock that has a three-dimensional space that does not collapse inward and is waterproof; (E) Assembling: the bottom of a sock of the three-dimensional sock in step (D) is attached to the sole to form A three-dimensional sock shoe; and (F) a three-dimensional sock shoe and a shoe last separation operation: the three-dimensional sock shoe in the step (E) is separated from the shoe last to obtain the rigid three-dimensional sock shoe.

However, the manufacturing method of the aforementioned three-dimensional socks and shoes with stiffness has many problems:

First, the manufacturing methods and procedures of the aforementioned three-dimensional sock shoes are too complicated, and the processes of steps B and C are quite labor-intensive and time-consuming. Each shoe last must be put on the inner sock body, the inner sock body is covered with adhesive, and the inner lining. After the sock body is initially shaped, the waterproof cover is put on, the waterproof cover is covered with adhesive, the outer sock body is put on, the drying combination and assembly operations, etc., can the three-dimensional sock shoe and the shoe last be separated and continue to be manufactured. A three-dimensional sock shoe will cause each shoe last to spend a lot of time on producing a shoe, which reduces the production efficiency and greatly increases the manufacturing cost.

Second, in order to achieve stiffness and waterproof effect, the three-dimensional sock shoes are deliberately covered with a layer of adhesive on the inner sock body and the waterproof cover. Two layers of adhesive are used to increase the stiffness of the sock and use The barrier effect of the two-layer adhesive and the waterproof case enhances its waterproof function. However, this kind of full-covering adhesive layer will completely block the moisture permeability of the waterproof jacket inside the socks and shoes, resulting in the uncomfortable feeling of sultry and stickiness when wearing, and the skin will be prone to allergies or skin Foot odor problem. Therefore, the practice of the conventional three-dimensional socks and shoes is obviously turning the cart before the horse, which is obviously to highlight the stiffness of the socks and shoes and give up the moisture permeability function of the socks and shoes.

Third, the aforementioned three-dimensional sock shoes are dried by using the adhesive located between the inner sock body and the waterproof sleeve to heat and solidify into a shaped bonding layer, and the adhesive between the waterproof sleeve and the outer sock body The adhesive is heated and solidified into a certain type of bonding layer, so that the inner sock body, the waterproof cover and the outer sock body are tightly combined with each other in a three-in-one manner to form a three-dimensional space that defines a foot and does not collapse inward And a three-dimensional socks with waterproof. However, after the inventor has tested it, it is difficult to tightly integrate the three-layer structure of the inner sock body, the waterproof jacket and the outer sock body with each other only by the physical and chemical properties of the adhesive. The concave structure on both sides of the arch and ankle is deformed or separated during the cooling process after drying.

For this reason, the inventor of this case specially studied the shortcomings and deficiencies of the aforementioned conventional socks and shoes, and invented this case.
