Abstract

The invention discloses a p reparation method of a novel polyester filament yarn fabric alkali weight reduction accelerant FY-01. The novel polyester filament yarn fabric alkali weight reduction accelerant FY-01 is prepared by compounding the following components in percentage by weight: 25%-35% of 3-chloro-2-hydroxypropyl dimethyl octadecyl ammonium chloride, 15%-25% of N,N-dimethyldiallyl ammonium chloride, 10%-12% of AE-07 polyoxyethylene ether, 5%-8% of iso-ol polyoxyethylene ether, and the balance of water. The 3-chloro-2-hydroxypropyl dimethyl octadecyl ammonium chloride and N,N-dimethyldiallyl ammonium chloride of the alkaline weight reduction accelerant are mixed, so that the uniform adsorption amount of cationic alkali weight reduction accelerants on the surface of the polyester filament can be increased so as to achieve better weight reduction effect, the uniformity is good, and the weight reduction rate is easily controlled; the polyoxyethylene ether is added for compounding, substances can be added into grooves in the surface of the polyester stripped and etched by sodium hydroxide, so that the hydrophilicity of the fiber can be increased to achieve the moisture absorption and sweat releasing functions, and the wearing comfortableness can be promoted.

Description

technical field [0001] The invention specifically relates to a preparation method of an alkali weight reduction accelerator FY-01 for polyester filament fabrics. Background technique [0002] Polyester alkali reduction refers to the process of treating polyester fabrics in high temperature and relatively concentrated caustic soda. After its surface is etched by alkali, its mass is reduced, the fiber diameter becomes thinner, pits are formed on the surface, the simple cut stiffness of the fiber decreases, the aurora of the polyester yarn is eliminated, and the interweaving point gaps of the fabric are increased, making the fabric feel soft and comfortable. The luster is soft and improved. [0003] The application number is 201310267553.9, the application publication number is: CN 103343445 A, the patent name is: Accelerator for polyester alkali weight reduction processing and its use method, the patent uses imidazole Gemini ionic liquids with different hydrophobic carbon cha...
