Abstract

The invention relates to the technical field of textiles, in particular to a preparation method and application of an organosilicone antistatic agent. The preparation method of the organosilicone antistatic agent comprises the following steps: adding low-hydrogen-content silicone oil and allyl alcohol polyoxyethylene ether into a reaction kettle provided with a reflux device; then adding a chloroplatinic acid solution; raising the temperature to 100-130 DEG C; performing a heat preservation reaction for 1-3 h after the system is transparent and clarified; and reducing the temperature and performing discharging, wherein the addition amount of chloroplatinic acid is 0.0005-0.0020% of the mass of the low-hydrogen-content silicone oil. As the low-hydrogen-content silicone oil is taken as the raw material to react with allyl alcohol polyoxyethylene ether with different activity, the reaction is complete, the conversion ratio is high, the product quality is stable, and such phenomena as polymerization and cross-linking are avoided. The organosilicone antistatic agent prepared by the preparation method has favorable hydrophilic hygroscopicity, the fiber surface specific resistance is greatly reduced, the antistatic effect is achieved, and the antistatic and washing-enduring requirements in the textile industry are satisfied.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a preparation method and application of an organic silicon antistatic agent. Background technique [0002] Synthetic fibers, yarns and the fabrics they form can have good toughness and aesthetic properties through production and processing, and are cheap, so they have been rapidly developed and widely used. At the same time, these textiles also have disadvantages that cannot be ignored, such as low hygroscopicity, poor dyeing performance, and easy accumulation of charges. [0003] The static electricity generated by textiles plagues people's daily life. For example, during the wearing process of clothes, the static electricity is easy to stick to dust and cause discomfort to the body; in textile production, static electricity during the spinning process will cause poor cohesion between fibers, It is easy to entangle and break the end, which affects the smooth progress of spinni...
