Thick polyester/cotton knitted fabrics can reduce creases greatly. The dense polyester/cotton and polyester knit fabrics are prone to creases during the bleaching process. This is a headache for dyeing technicians. The requirements are constantly improving, and the first-line dyeing and dyeing workers are constantly exploring, experimenting, and improving. Develop a series of preventive improvement measures. Today, we will explore some of the dyeing frontier technologies to prevent creases. 
1 dyeing machine selection:
It is difficult for a woman to be without rice. The equipment is the foundation. Its quality is directly related to the quality of the product. Most dyeing factories use various types of U-shaped, L-shaped or O-shaped water dyeing machines, although the nozzle is changed from 80MM to 80mm. 100MM or even 120MM, the main pump frequency is adjusted to 45-50HZ, the effect is still not ideal. With the continuous updating of the equipment, we can now choose the airflow dyeing machine and the vapor dyeing machine to produce the fan according to the width and weight of the door and the length of the cloth. Operating parameters such as main pump and machine speed, especially the air volume of the fan, can blow the cloth to prevent the folding of the cloth at the same place for a long time, resulting in creases.
2 process development:
The process is the core technology of bleaching and dyeing. The training and contact equipment, cloth and dyeing materials of each company's technicians are different, so the bleaching and dyeing formulas and processes and production processes are different.
