How to repair the defects of the dyeing machine?

1. Prevention and repair of folds: Dyeing with overflow jet dyeing machine, the fabric is basically in a tension-free state. Practice has proved that there are five main factors for the formation of folds:
① Potential factors in textiles.
② The thermal shrinkage of two or more fibers that make up the fabric is inconsistent.
③ The size of the dyeing bath ratio.
④ Dyeing rises/cools too fast.
⑤ Select machines for processing according to dyeing products and requirements.
2. Repair of color flower: The color flower on the overflow jet dyeing machine is generally caused by mechanical problems, often due to the dyeing of light-medium color, the small amount of dye used, the poor effect of the uniform dye, the dyeing process heating up too fast and the chemical There are many reasons such as incorrect materials and careless addition of materials.
3. Restoration of dyed spots: the high temperature and high pressure overflow jet dyeing machine must often produce dyeing spots when dyeing various polyester and its blended fabrics. Therefore, first, the treatment and alkali reduction of polyester and its blends before dyeing are important. In addition, good disperse dyes should be selected, and only additives can be added to make up and improve.
