Embodiment approach

[0058] 1B: Turn the one-piece structure inside out, the reverse side of the weft stitch is outside, and the front side is inside;

[0059] 1C: Sew up the opening of the front head (6) of the second sock part;

[0060] 1D: From the opening of the front head (5) of the first sock part, pass the foot mold through the inside of the first sock part and insert it into the inside of the second sock part. The foot mold is a shoe last with a shape and dimensions are consistent with said first sock portion and said second sock portion;

[0061] 1E: placing the seamless sock-shaped waterproof and moisture-permeable PU membrane sleeve (3) outside the second sock part (2);

[0062] 1F: Turn the first sock part (1) backwards and put it on the outside of the PU film sleeve (3) and the second sock part (2);

[0063] 1G: Sew the opening of the front head (5) of the first sock part to form a three-layered sock with the interlayer containing the PU film sleeve (3);

[0064] 1H: heating and se...

Embodiment 1

[0079] Make three-layer waterproof shoes of the present invention according to the following steps:

[0080] 0A: Knit the head 5 of the first sock on the single-needle bed hosiery machine. The veil of the sock is made of cotton and nylon fibers, and the bottom yarn is made of leather-core low-melting yarn (melting point 80~130°C);

[0081] 0B: knitting the sock face 8 and sock sole 10 of the first sock part 1 by unidirectional rotation of the needle cylinder;

[0082] 0C: The reciprocating rotation of the needle cylinder first gradually reduces the knitting needles participating in knitting, and then gradually increases the knitting needles participating in knitting, so as to knit the heel 12 of the first sock;

[0083] 0D: The needle cylinder rotates in one direction to knit the first sock part and the second sock part sock tube 4, and the middle part of the sock tube is lined with elastic or spandex (the opening of the sock is formed here when double-layer socks are turned o...

Embodiment 2

[0097] Before or at the same time as making the three-layer waterproof shoes of the present embodiment, the PU film cover 3 can be prefabricated, and this step (step 1E-0) includes the following sub-steps:

[0098] 1E-01: Do double-sided dot-like glue coating on the PU film on the compound machine;

[0099] 1E-02: Two layers of dotted glued PU film are pressure-heated under the sock-shaped mold. The heat source used is high-frequency electromagnetic wave (high frequency wave), and the pressure of the mold on the PU film is 0.1~8kg / cm 2 , the characteristic polar covalent bonds of the glue-coated molecules and polymers of the PU film heat up to the welding temperature under the action of high-frequency waves, resulting in bonding and fixing;

[0100] 1E-03: Cut the laminated double-layer film at the central line of the sock-shaped rubber coating below the heat-sealing temperature of the PU film to obtain a sock-shaped seamless PU film sleeve 3 with an opening at the ankle.

Abstract

The invention discloses a making method of a three-layer seamless composite waterproof shoe. The making method sequentially includes following steps: weaving an integral structure comprising a first sock portion and a second sock portion on a single-needle-bed hosiery machine through one-time forming; enabling a foot-shaped die to penetrate the inside of the first sock portion from a front openingof the first sock portion to sleeve into the second sock portion; sleeving a seamless sock-shaped waterproof moisture-permeable PU film outside the second sock portion; backwards turning the first sock portion, stitching the front opening of the first sock portion, and heating to set a three-layer-structure sock sleeving a shoe tree to form an integral three-layer seamless composite vamp; combining the three-layer-structure sock or the vamp with a sole. The making method has the advantages that the process is reliable, simple, convenient and high in efficiency, and the three-layer seamless composite waterproof shoe is comfortable to wear, soft in hand feel and high in firmness, waterproofness and heat insulativity.

Description

technical field [0001] The invention belongs to the field of shoemaking, and in particular relates to the technical field of waterproof shoe making methods. Background technique [0002] Patent "Seamless Integrated Knitted Upper Waterproof and Moisture-permeable Sock Shoes" (application number 201520471079.6), the upper has a three-layer composite fabric structure, which is composed of an outer layer, an inner layer and a middle layer, and the middle layer is placed between the inner and outer layers. It is one-time glued and molded by hot melting, and the upper and the sole are bonded together by cold bonding or vulcanization. This patent document discloses that the integral waterproof vamp is formed by laminating the waterproof and moisture-permeable membrane structure with the outer layer and the inner layer with hot melt adhesive through a special one-time molding composite mold. Its shortcoming is that it does not disclose how the outer layer of knitted material and th...
