Dyeing and finishing precautions
1. Pre shrinkage should be carried out before dyeing and finishing to make sys shrink and show elastic characteristics.

2. Disperse dye is used for dyeing. Dyeing temperature is 115-125 ºC. Pay attention to holding time. Too high temperature will affect elasticity.

3. The setting temperature shall not exceed 170 ºC to avoid excessive stretching. The reference is fabric elasticity and hand comfort.
