Chemical softening is the softening of fabric with a softener. The role of softener is to reduce the friction between yarn and fabric, reduce the friction between fiber and fabric and human body.
Silicone oil is known for its greater stability and non-toxic use at high temperatures, low surface tension and high diffusion force. It is a mixture of polydimethylsiloxane (PDMS) and dimethylsiloxane and dimethylsiloxane.
In the dyeing process, various dyeing auxiliary agents such as dispersant and levelling agent for levelling, reducing agent and soaping agent for washing unfixed dyes to improve dyeing fastness, fixing agent for cotton and nylon dyeing, etc.
