1. The production process of the integrally formed PU vamp is characterized by comprising the following operation steps:

s1: according to the design requirements, firstly designing a pattern formed by an integrated vamp, and engraving the pattern on a steel roller for later use;

s2: transferring the patterns on the steel roller in the step S1 to release paper on a production line for producing the release paper to produce the release paper of the integrated shoe type;

s3: coating a layer of PU leather on the patterned surface of the release paper in the step S2, and baking and shaping the PU leather into integrated shoe leather by an oven;

s4: and (4) cutting the integrated shoe-shaped leather produced in the step (S3) into a complete vamp according to the outer frame line of the shoe-shaped leather by using a laser cutting machine, namely, the vamp is an integrally formed PU vamp.

2. The process for producing an integrally formed PU upper according to claim 1, wherein: the temperature of the oven is 100-120 ℃.

Technical Field

The invention relates to the technical field of fabric production, in particular to a production process of an integrally formed PU vamp.

Background

The surface of the existing PU leather has the same pattern, and the splicing sewing is needed if different pattern effects are reflected on different parts of a vamp, so that the production process has the following problems: the sheets with each pattern need to be placed on a die one by one for blanking, the time is long and the cost is high; the punched sheets are sewn into a vamp through a back needle machine, and the manufacturing workload is large and the labor cost is high.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention aims to provide the production process of the integrally formed PU vamp, which is simple, low in cost, high in production efficiency and high in product quality.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the production process of the integrally formed PU vamp comprises the following operation steps:

s1: according to the design requirements, firstly designing a pattern formed by an integrated vamp, and engraving the pattern on a steel roller for later use;

s2: transferring the patterns on the steel roller in the step S1 to release paper on a production line for producing the release paper to produce the release paper of the integrated shoe type;

s3: coating a layer of PU leather on the patterned surface of the release paper in the step S2, and baking and shaping the PU leather into integrated shoe leather by an oven;

s4: and (4) cutting the integrated shoe-shaped leather produced in the step (S3) into a complete vamp according to the outer frame line of the shoe-shaped leather by using a laser cutting machine, namely, the vamp is an integrally formed PU vamp.

Further, the temperature of the oven is 100-120 ℃.

Compared with the prior art, the invention has the following beneficial effects:

1. the manufacturing process of the invention saves the cost and time for manufacturing the blanking die and reduces the cost; the labor cost of the sewing machine in a shoe factory is saved; saving material and reducing material waste.

2. Different patterns can be embodied at different positions on the integrally formed PU vamp, and the integrally formed PU vamp is produced at one time without splicing and sewing, so that the cost of workers is reduced, and the loss is reduced.
