Softeners can be roughly divided into two categories: fatty acid derivatives and silicone.


Fatty acid derivatives are traditionally widely used softeners, and silicones are the new varieties. The development of silicone softeners is very fast, and new products with various properties and functions are constantly being developed and listed.


Because the silicone softener is not only better than the fatty acid derivative softener, but also has good durability, it has occupied the main position in the use of textiles after softening. However, precisely because of its good durability effect, it also brings certain difficulties to removal, making it difficult to repair or repair dyeing. If the silicone oil spot is more headache, it is difficult to repair.


Silicone softeners are mostly cationic, weak cationic or non-ionic in ionic property. Therefore, in the production and processing, it is often treated with the same bath as the fixing agent, and the treatment bath temperature is generally 30 ~ 45 ° C. Do not wash after soft treatment, after baking its reaction film fastness is higher. If not properly operated, silicone softeners are easy to break emulsion and drift oil problems. Some need to be processed in the dyeing machine, such as clothing, yarn, loose fiber, after dyeing in the dye tank on the softener, etc., after a long time, it is easy to occur the residue of silicone substances in the equipment. It is more difficult to remove and repair than fatty acid derivative softeners.
