Cashmere sweaters (pants) are soft, smooth, warm and comfortable to wear and have good elasticity. They are popular among consumers, but they are expensive. The wool is rough, stiff, and thorny, but the output is large and the price is relatively cheap. After finishing the cardigan (pants) with silicone smoothing agent, you can get a smooth, soft, fluffy and high-elastic feel, and its added value is greatly improved. Therefore, silicone smoothing agent has been one of the research and development hotspots in the textile field in recent years. Although amino silicone oil can give wool fabrics excellent softness, it is not slippery and lacks elasticity, and high-molecular-weight methyl silicone oil can greatly reduce the friction coefficient between fibers, which can give wool fabrics a smooth feel, but Poor softness and lack of fluffiness. In order to obtain the ideal finishing style for wool fabrics, and considering the effect of the amino value of amino silicone oil on yellowing and softness of wool fabrics, amino silicone oil emulsions with different ammonia values and molar masses and methyl silicone oil emulsions with high molar mass were prepared in this experiment It is compounded, and the synergistic effect between the components is used to select the silicone smoothing agent that can give the wool smoothing agent, soft, full, bright and other styles.

Preparation method of silicone fabric smoothing agent

A preparation method of silicone fabric smoothing agent, which uses ultra-high viscosity hydroxyl-terminated dimethyl silicone oil and low-viscosity dimethyl silicone oil to reduce viscosity, mix with emulsifier and then emulsify by phase inversion method, then use high speed Shearing emulsifier emulsified to prepare silicone smoothing agent emulsion, and added smoothing synergist nano-oxidized polyethylene wax emulsion to prepare silicone fabric smoothing agent. Compared with the prior art, the present invention has the advantages of adopting a one-step preparation process and applying high-shear thinning emulsification technology for the first time, adopting an environmentally friendly emulsifier, and making a silicone fabric containing only ultra-fine particles at room temperature to be smooth Agent, the smoothing agent has good storage stability, solves the technical problem that conventional smoothing agents are easy to delaminate, and has better filling, fixing, fluffy and smoothing effects on fabrics. The smoothing agent is suitable for post-processing of wool, pure cotton, chemical fiber and blended fabric.
