Problems solved by technology

[0002] Mesh and hot-melt film are more and more widely used in sports shoes. This form of sports shoes is more and more popular among young people. However, the manufacturers of this type of synthetic leather in the existing market use TPU film and After the mesh is punched separately, it will be composited separately and then provided to the shoe factory. The production process of the synthetic leather will bring about increased labor costs and low efficiency. We are providing a new type of mesh combined with hot-melt TPU. The Huaburun synthetic leather produced by this method can effectively solve the above problems, obviously improve the efficiency of shoemaking and reduce the cost of shoemaking

Embodiment Construction

[0018] figure 1 Schematic diagram of the structure of Huabulun synthetic leather made for the present invention

[0019] As a specific embodiment of the present invention, the production method of a kind of flower Burun synthetic leather described in the present invention comprises the following steps:

[0020] 1. Mix and prepare polyurethane fabric resin, dimethylformamide, methyl ethyl ketone and color chips according to 100:60:20:10-15, and stir at a stirring speed of 1000-1500 rpm at room temperature for 5- 10 minutes until completely dissolved. After stirring, filter with 150 mesh and seal to prevent water absorption. After mixing, the viscosity of polyurethane fabric remains at 2500-3000cps / 25℃;

[0021] 2. Mix and prepare thermoplastic polyurethane primer resin, dimethylformamide, butanone, heat stabilizer and leveling agent in a ratio of 100:120:60:6:0.3, and use 500-1000 Stir at 1200-1500 rpm for 5 minutes, then stir at 1200-1500 rpm for 20 minutes until the particl...

Abstract

The invention relates to a production method combining screen cloth and hot-melt TPU and in particular relates to a method for producing jacquard synthetic leather. The process flow of compounding and integrating the TPU and screen cloth is provided, the jacquard synthetic leather through which the screen cloth and the hot-melt TPU are well combined can be produced at one time by adopting the method, and the key points and difficulty of the process flow refer to control over softening point of TPU and curing temperature and pretreatment of the screen cloth. The method comprises the following steps: preparing a polyurethane fabric, preparing a bottom material, treating the screen cloth, respectively combining the two layers of polyurethane fabric, bottom material, TPU hot melt film and screen cloth on release paper by virtue of a special process, and thus manufacturing the jacquard synthetic leather.
