Problems solved by technology

[0004] If the existing TPU high and low temperature film composite cloth is to be made into a three-dimensional effect, it is necessary to set up a specific mold for processing. To make different three-dimensional graphics, more combinations of molds are needed for matching. However, the cost of mold opening is high. The cost of opening multiple modular molds is higher

Embodiment 1

[0024] A processing method of TPU high and low temperature film composite cloth, comprising the following steps:

[0025] (S1), take the tool and place it on the stage of the hot pressing equipment, and then take the TPU high and low temperature film and arrange it on the surface of the tool; wherein, the side of the tool where the TPU high and low temperature film composite cloth is placed is uneven flat;

[0026] (S2), pressing the soft heat-conducting layer of the hot-pressing equipment to the TPU high-low temperature film composite cloth for hot-pressing treatment, so that the TPU high-low temperature film composite cloth and the tool are pressed and deformed;

[0027] (S3) After hot pressing, the tool and the TPU high-low temperature film composite cloth are transferred as a whole to the stage of the shaping equipment for film setting treatment, and then the film is taken to obtain a three-dimensional TPU high-low temperature film composite cloth.

[0028] The processing...

Embodiment 2

[0043] The difference between embodiment 2 and embodiment 1 is:

[0044] In this embodiment, the tool is provided with a plurality of air guide holes, and the step (S2) further includes: vacuumizing during the hot-pressing treatment. The hot pressing equipment is a vacuum hot negative pressure blister machine with a soft heat conducting layer.

[0045] Adopting the above technical scheme, the TPU high and low temperature film composite cloth is promoted to be closely against the surface of the tool during the hot pressing process, and the shape of the TPU high and low temperature film composite cloth is promoted, and the contour of the surface of the three-dimensional TPU high and low temperature film composite cloth is more perfect. fine.

[0046] In this embodiment, the soft heat-conducting layer is a heat-conducting silicone film with a thickness of 0.3-0.5 mm, which can be deformed according to the opening shape of the tool during vacuuming and negative pressure thermal p...

Abstract

The invention relates to the technical field of processing of TPU (Thermoplastic Polyurethane) high-low temperature film composite cloth, in particular to a processing method of the TPU high-low temperature film composite cloth. The method comprises the following steps: (S1) placing a manufacturing tool on a carrying table of hot pressing equipment, and then placing TPU high-low temperature film composite cloth on the surface of the manufacturing tool, wherein one surface, on which the TPU high-low temperature film composite cloth is placed, of the manufacturing tool is an uneven surface; (S2) pressing a soft heat-conducting layer of the hot-pressing equipment on the TPU high-low temperature film composite cloth for hot-pressing treatment, so that the TPU high-low temperature film composite cloth and the manufacturing tool are pressed and deformed; and (S3) after hot pressing, integrally transferring the manufacturing tool and the TPU high-low temperature film composite cloth to the carrying table of shaping equipment to carry out film shaping treatment, and taking the film so as to obtain stereoscopic TPU high-low temperature film composite cloth. The processing method is adopted to replace a method for manufacturing the stereoscopic TPU high-low temperature film composite cloth by adopting a mold, and the manufacturing cost is more effectively saved.

Description

technical field [0001] The invention relates to the technical field of processing TPU high and low temperature membrane composite cloth, in particular to a processing method of TPU high and low temperature membrane composite cloth. Background technique [0002] TPU high and low temperature film is widely used in various textile fabrics such as shoe materials, clothing, luggage, etc. because of its simplicity, softness, elasticity, and ease of use. It is one of the preferred materials for fashion leisure and sports brands; for example: sports shoes Industry's uppers, tongue labels, trademarks and decorative accessories, straps for bags, reflective safety labels, LOGO, etc. [0003] TPU high and low temperature film composite cloth is mostly composed of TPU high and low temperature film and mesh cloth or synthetic leather. [0004] If the existing TPU high and low temperature film composite cloth is to be made into a three-dimensional effect, it is necessary to set up a speci...
