1. The fabric is not shaped by high temperature
1 acetic acid washing
2 solvent type degreaser treatment at high temperature.


2. The fabric has been set at high temperature
Dedicated fluorinated and silicon based strippers are treated under alkaline conditions.
The main principle is to hydrolyze the fluorosilicon chain by boiling under alkaline conditions, and then emulsify and disperse the hydrolyzed fluorosilicon segment in time by means of the emulsification and dispersing ability of the fluorosilicone stripping agent. Thereby the removal of the silicone oil spots and the waterproof spots is completed.


Note that it is difficult to remove the method of adding deoiling and hydrogen peroxide on the basis of alkali and fluorine stripping agent. In addition, according to the severity of waterproof spots and silicone oil spots, the amount of stripping agent can be appropriately increased. Under the removal, the number of removal passes can be appropriately increased to complete the spot removal.


For regenerated cellulose fibers or protein fibers, it is recommended to use soda ash to adjust the pH of the treatment bath to 8.5-9.5 due to its poor alkali resistance to avoid strong damage or excessive protein loss.






3. Silicone oil
When the amino silicone oil emulsion is used together with a fixing agent or a soft oil, silicon plaque sometimes occurs. When it is used alone, why?


Amino silicone oil is incompatible with additives such as fixing agent and soft oil, resulting in silicone oil.


Amino silicone oil emulsion is a cationic surfactant (or weak cation). Many chemicals used in the dyeing process are anionic surfactants, such as: dyes (some dyes are anionic), leveling agents, diffusing agents, fixing Agent. . . After the dyeing and finishing of these chemicals, before the soft finishing, once the water washing is not thorough, when the cationic amino silicone oil softener reacts with the anionic substance in the dyeing bath, the aminosilicone oil cationic emulsion will be demulsified and the oil will be softened. Spot (silica spot), an effective way to enhance the full washing before soft finishing, it is best not to softly finish in the same dyeing machine. After the dyeing is washed, the fabric is poured out and softly finished in the rolling cart.


Note: The special cylinder is too soft to effectively avoid or reduce the formation of soft spots (silicon spots).
