Problems solved by technology

[0002] The surface of the existing PU leather is the same pattern, and if different parts of a vamp want to reflect different pattern effects, they need to be spliced ​​and sewn. This kind of production process has the following problems: each pattern sheet needs to be One by one is placed on the mold for punching, which takes a long time and high cost; after punching, the sheet is sewn into a shoe upper by sewing, which requires a lot of work and high labor costs.

Embodiment 1

[0019] Refer to as figure 1 and figure 2 As shown, the production process of the integrally formed PU upper includes the following steps:

[0020] S1: According to the customer's demand for the shoe upper pattern or the designer's design, first design the integrated shoe upper pattern, engrave the above pattern on the steel roller, and wait for the subsequent processing process to be used;

[0021] S2: Transfer the pattern on the steel roller 1 in the above step S1 to the release paper 2 on the production line for the production of release paper, so that the integrated shoe-shaped release paper 2 can be produced. The production of the release paper is mainly It is the transfer pattern used for the subsequent leather;

[0022] S3: Place the release paper 2 in step S2 on the production line for transmission. During the transmission process, the pattern surface of the release paper 2 is coated with a layer of PU leather material, and then baked in an oven at 100°C to 120°C to ...

Abstract

The invention discloses a production process of an integrally-formed PU vamp. The process comprises the following operation steps: S1, designing integrally-formed vamp patterns according to design requirements, and carving the patterns on a steel roller for later use; S2, transferring the patterns on the steel roller in the step S1 to release paper on a release paper production line to produce integrated shoe-shaped release paper; S3, coating the release paper pattern surface in the step S2 with a layer of PU leather, and baking and shaping through an oven to form integrated shoe-shaped leather; and S4, cutting the integrated shoe-shaped leather produced in the step S3 into a complete vamp by using a laser cutting machine according to the shoe-shaped outer frame line, wherein the vamp is an integrally-formed PU vamp. The manufacturing process saves the cost and time for manufacturing a blanking die, and the cost is reduced; the labor cost of sewing machines in shoe factories is saved;and materials are saved, and material waste is reduced.

Description

technical field [0001] The invention relates to the technical field of fabric production, in particular to a production process for an integrally formed PU shoe upper. Background technique [0002] The surface of the existing PU leather is the same pattern, and if different parts of a vamp want to reflect different pattern effects, they need to be spliced ​​and sewn. This kind of production process has the following problems: each pattern sheet needs to be One by one is placed on the mold for punching, which takes a long time and high cost; after punching, the sheet is sewn into a shoe upper by sewing, which requires a lot of work and high labor costs. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the object of the present invention is to provide a production process for integrally formed PU shoe uppers, which is simple, low in cost, high in production efficiency and high in product quality. [0004] In order to...
