Embodiment Construction

[0027] The PU synthetic leather used in this embodiment is the PU synthetic leather produced by the composite production process of first wet method and then dry method. Used spray drying machine, dermabrasion machine, dry kneading machine, softening machine, embossing machine, polishing machine, printing processing machine are all commonly used equipment in this technical field.

[0028] A post-treatment method for PU synthetic leather, comprising the following steps:

[0029] ① Spraying process: also known as the spraying process, it is introduced from the technology of leather treatment. In the specific technical solution of the present invention, the spraying process is carried out in a computer-controlled spray dryer. Specifically, after the spraying agent composed of resin, pigment and solvent is prepared in a certain proportion, it is transported to the spraying room of the spray dryer by a liquid pump; m / min; Put the sprayed PU synthetic leather into an oven for dryi...

Abstract

The invention discloses a post-treatment method for PU synthetic leather. According to the method, various post-treatment technology, concretely comprises a spraying process, a leather grinding process, a line rubbing process, a surface printing process, a surface polishing process and a printing process, are added based on dry and wet processes of current technology. The PU synthetic leather post-treated by the method has greatly improved flexibility, vertical sense, straight sense, lines and patterns; and the using effect of the PU synthetic leather is closer to, even better than leather.

Description

technical field [0001] The invention relates to a post-treatment method of PU synthetic leather, which belongs to the technical field of synthetic leather manufacture. Background technique [0002] The appearance and internal performance of PU synthetic leather products are very similar to those of natural leather. Generally speaking, PU synthetic leather products include surface coating layer, coloring layer, microporous layer, base fabric and imitation leather structure layer. [0003] PU synthetic leather has a wide range of uses. Because it has a wide variety of base fabrics, textures of various colors, and has the characteristics of stable batches and good overall processing performance, it is widely used in shoemaking, luggage manufacturing, Apparel manufacturing, furniture decoration, sporting goods, military industry, medicine, aviation and other fields. At present, the total domestic demand for synthetic leather is predicted to be 1.5 billion m3 per year. 2 More ...
