Problems solved by technology

[0003] In order to solve the problem in the prior art that only the two-step gluing method can achieve the proper adhesive strength of the upper, the present invention provides a shoe-making upper and its single gluing method, which only needs one step of gluing. Realize the helper foot to achieve the desired adhesive strength

Embodiment Construction

[0019] Such as Figure 1-3 As shown, a shoe-making helper includes a helper piece 1 coated with a treatment agent 5 and an adhesive on one side of the outer surface in sequence, and hook holes 2 are opened on the helper piece 1 at the corresponding positions coated with the adhesive. Or be provided with sewing thread 3 or be provided with crochet needle hole 2 and combine with sewing thread 3. The adhesive can effectively penetrate into the fibers of the inner layer of the upper sheet 1 through the hook holes 2, so as to achieve a stronger bonding effect.

[0020] In order to increase the permeability of the adhesive and the treatment agent to increase the bonding strength, the inner layer fibers of the side piece 1 protrude outward along the hook holes 2, and the protruding inner layer fibers are hook and leak fibers 201 .

[0021] In order to further increase the amount of penetration, the sewing thread 3 extends along the application direction of the adhesive.

Abstract

The invention discloses a shoe-making upper and a single-glue coating method thereof, which comprises an upper which is coated with a treatment agent and an adhesive in sequence on one side of the outer surface, and crochet needles are provided on the upper corresponding to the position coated with the adhesive. Holes are either set with sewing thread or set crochet holes combined with sewing thread. The inner layer fibers of the side piece protrude outward along the crochet holes, and the protruding inner layer fibers are hook leak fibers. The sewing thread extends along the application direction of the adhesive. The crochet holes occupy at least one-third of the corresponding positions on the upper sheet where the adhesive is applied. Said sewing thread accounts for at most two-thirds of the corresponding positions on the upper sheet where the adhesive is applied. Compared with the prior art, the present invention utilizes the physical methods of acupuncture and stitching, and the chemical method of treatment agent coating treatment which is beneficial to cross-linking and increases the activity of the adhesive surface to carry out the auxiliary treatment, and realizes only a single application of glue The method can achieve the proper bonding strength, optimize the process, and realize the production process of green environmental protection, low cost and high quality.

Description

technical field [0001] The invention belongs to the technical field of shoemaking, and in particular relates to an upper for shoemaking and a single glue-coating method thereof. Background technique [0002] At present, in addition to the treatment agent, first apply a layer of glue and dry it, then use the same method to brush the second layer of glue, dry it, and finally inject molding, that is: brush treatment agent, dry → brush a layer of glue, dry Drying → secondary glue brushing, drying → glue injection molding, through these key processes, it can be combined with the bottom of the glue injection product to achieve the proper bonding strength. However, with the requirements of product upgrading and green production, the existing method of secondary gluing does not meet the current advocated "optimize the process, improve efficiency and quality" requirements, so it is necessary to ensure the adhesion In the case of strength, further optimize the process.
