mauve cotton fabric

At the same time, if the impurities and auxiliaries on the fabric are partially degraded due to the influence of baking, once the degraded substances migrate to the inside of the fiber to produce marks, these marks will be difficult to remove in the subsequent processing. When dyeing, the oil spots inside the fiber will first absorb the dye, and they will not be able to escape in time during the heat preservation and dyeing process, forming dark spots. Even if the color is stripped and re-dyed, it will remain on the fabric. Therefore, high-temperature pre-forming above 195°C (Platform Jun Note: The softening temperature of spandex is about 200° or more), which will also affect the spandex fastness. The width of the fabric during shaping is 10% to 15% wider than the blank fabric, so that it can have a sufficient recovery during pre-treatment in the dyeing tank, so that the stress inside the fabric is completely eliminated.
