Abstract

The invention provides an imitation leather dyeing technology. The technology comprises the following steps: carrying out a pretreatment, weighing, dyeing, performing color matching, dehydrating, semi-drying, processing with balls, heating, polishing, performing wind-blowing, and finishing. A ball-processing technology is used in the technology, balls rolls over on the surface of imitation leather, during the rolling process, the pigments on the imitation leather are adhered onto the balls, and the pigments on the balls then are adhered onto the imitation leather again. After the processing, the imitation leather may have lines and texture just like the real leather. A special dyeing technology is adopted so as to enable the imitation leather to have the same texture as the real leather after dyeing.

Description

technical field [0001] The invention relates to the field of leather products, more specifically, to a dyeing process for imitation leather. Background technique [0002] Leather clothing is a relatively high-end garment in clothing. It is made of animal skins that are artificially processed into leather and cut into clothing. The utilization rate is low and the cost is high. The goods are scarce, and ordinary consumers are discouraged. [0003] In order to meet the needs of ordinary consumers, the company and Zhongtianjin Garment Co., Ltd. jointly developed the dyeing of imitation leather garments. Garment dyeing production reached 600,000 pieces. [0004] The early imitation leather is the artificial leather that people all know, but there is a big difference in the simulation effect. There is no crepe feeling, the leather surface is too flat and the gloss is too bright. It is an imitation at a glance. It is generally used for sofas, Furniture. Contents of the inventio...
