Such softeners are emulsions or microemulsions of polysiloxane and its derivatives, which can give the fabric a good soft and smooth feel. Products are emulsion polymerization, polymer silicone oil emulsification and modified, compound and other production furan, has basically formed a system, the supply of varieties and brands are also more. However, the application effect and performance are still very different.
1, dimethyl silicon emulsion: this is the earliest application of silicone softener products, used as a softener silicone oil relative molecular weight is generally 60,000-70,000. After finishing, it can give the fabric smooth, stiff and cool feel, reduce the friction coefficient of the fabric, and improve the wear resistance and sewability of the fabric. However, because there is no reactive group on its molecular chain, it can not react with the fiber, nor can it cross link itself, but only rely on molecular primer and adhesion on the fiber surface, so the washing resistance is poor, the increase of elasticity is also limited.
