Different classifications of common softener agent
Softener agent are the most diverse and the largest amount of dyeing and finishing auxiliaries. At present, the softener agent on the market are mainly divided into the following categories:
Anionic softener agent
In addition to soap, sulfonated oil, etc., the anionic softener agent is mainly composed of cationic compounds or anionic and nonionic compounds with long chain alkanes such as stearyl succinate sodium sulfonate and stearyl ester sulfate. Generally, it has good wettability and thermal stability, can be used in the same bath with fluorescent whitening agent, and can be used as a softener agent for extra-white fabrics.
Non-ionic softener agent
Non-ionic softener agent are generally polyoxyethylene decaacid, pentaerythritol, or fatty ester of sorbitol. Since non-ionic softeners have poorer absorption to fibers than ionic softeners, they can only have a smoothing effect.
Cationic softener
Mainly because most fibers are negatively charged in water, cationic softeners are easily adsorbed on the surface of the fibers, have strong binding ability, can withstand high temperatures and wash, and the fabrics are plump and smooth after finishing, which can improve the wear resistance and wear resistance of the fabrics. It has a strong tearing force and has a certain antistatic effect on synthetic fibers.
Amphoteric softener agent
Amphoteric softeners are a type of softener developed to improve cationic softener agent. It has a strong affinity for synthetic fibers, and has no disadvantages such as yellowing and discoloration of dyes. It can also be used in the re-training process of silk to make the silk feel better. Amphoteric softeners can also be used together with cationic softeners to play a synergistic effect. Such softeners are generally of alkylamine lactone type structure.
Silicone softener agent
This kind of softener agent is an emulsion or microemulsion of polysiloxane and its derivatives, which can make the fabric have a good soft and smooth hand feeling. The products include emulsion polymerization, polymer silicone oil emulsification, modification, compounding and other production techniques, which have basically formed a system and supply more varieties and brands. But the application effect and performance are still very different.
Anionic softener agent
In addition to soap, sulfonated oil, etc., the anionic softener agent is mainly composed of cationic compounds or anionic and nonionic compounds with long chain alkanes such as stearyl succinate sodium sulfonate and stearyl ester sulfate.
