Importance of processing before printing and dyeing pre-processing workshops

Practice bleaching workshop is a very important part of printing and dyeing plants. According to the statistics of quality analysis, there are 707 in the printed fabrics. The above quality problems are related to poor pre-treatment. Without good practice semi-finished products, it is impossible to produce a good finished cloth. Therefore, the implementation of the post responsibility system to improve the process of training and bleaching workshop processes, the rate of equipment, equipment in good condition to ensure that the quality of the next step down the machine, to produce a qualified practice bleaching and semi-finished products is to ensure the quality of printing and dyeing products. Some problems such as wrinkles and creases that occur during rinsing and bleaching process become quite flat after being mercerized, and semi-finished products with poor desizing and scouring are not easily detected when the cloth is dropped on the table. However, after treatment, the rickets of the pre-treatment were immediately exposed.

In the production practice, it can be seen that some semi-finished products that have not reached pre-processing quality but do not pass off have problems such as cloth noodles, uneven dyeing, chromatic aberration in the edges, chromatic aberration before and after, front and back chromatic aberration, creases, etc., and have to stop the dyeing process. Return to the practice bleaching workshop for repair. In the printing and dyeing factories, there are "seven-fold bleaching and three-point dyeing" statements, emphasizing the importance of practice and bleaching. A good printing and dyeing factory must have a good pre-processing plant (including good hardware and software) for printing and dyeing. The consensus of industry professionals.
