Embodiment approach

[0052] 1b: Turn the one-piece structure inside out, the reverse side of the weft stitch is outside, and the front side is inside;

[0053] 1c: Sew up the opening of the front head (6) of the second sock part;

[0054] 1d: Put the first sock part (1) and the second sock part (2) sequentially into the foot mold from the opening of the front head (5) of the first sock part, and the shape of the foot mold is matching or matching the size and size of the first sock portion and the second sock portion;

[0055] 1e: placing the seamless sock-shaped waterproof and moisture-permeable PU film sleeve (3) outside the second sock part (2);

[0056] 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);

[0057] 1g: Sew up 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);

[0058] 1h: Heat and set the socks with the three-layer ...

Embodiment 1

[0072] Before or at the same time as making the three-layer waterproof socks of this embodiment, the PU film cover 3 can be made in advance, and this step (step 1e-0) includes the following sequential steps:

[0073] 1e-01: Double-sided point-like glue coating on the PU film on the compound machine;

[0074] 1e-02: Two layers of dot-coated PU films are pressure-heat-sealed under a sock-shaped mold. The heat source used is high-frequency electromagnetic waves (high-frequency waves), 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;

[0075] 1e-03: Below the heat-sealing temperature of the PU film, the laminated double-layer film is cut at the centerline of the sock-shaped rubber coating to obtain a sock-shaped seamless PU film sleeve 3 with an opening at the ankl...

Embodiment 2

[0094] Make the three-layer waterproof socks of the present invention according to the following sequential steps:

[0095] 0a: Knit the head 5 of the first sock part of the sock body at the beginning of 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 low-melting point yarn (melting point 80~130°C);

[0096] 0b: knitting the sock face 8 and sock sole 10 of the first sock part 1 by unidirectional rotation of the cylinder;

[0097] 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;

[0098] 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 h...

Abstract

The invention discloses a making method of three-layer seamless composite waterproof socks. For each sock, the making method sequentially comprises the following steps: implementing integrally shapingand knitting on a single-bed knitting machine so as to obtain an integrated structure which comprises a first sock part and a second sock part; from an opening in the front side of the first sock part, leading a foot-form mold run through the interior of the first sock part and bush into the second sock part; arranging a seamless sock-form waterproof and moisture-permeable PU film cover outside the second sock part; turning the first sock part backwards; seaming the opening in the front side of the first sock part; heating and shaping the sock of a three-layer structure sleeved on a shoe tree; and melting low-melting-point yarns so as to weld the second sock part, the PU film cover and the first sock part, so that the integrated three-layer seamless composite waterproof sock is formed. The making method provided by the invention has the advantages of being reliable and convenient in process, high in efficiency, comfortable to wear, soft in hand feeling, good in firmness, good in waterproofing performance and good in warm-keeping performance.

Description

technical field [0001] The invention belongs to the field of socks, in particular to the technical field of waterproof socks manufacturing 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 the inner l...
