Abstract

The invention discloses a preparation method of a spinning hot-melting sizing agent for polyester cotton. The preparation method specifically comprises the following steps: 1, adding maleic anhydride, vinyl acetate, methyl methacrylate and acrylamide as reaction units into a three-opening flask, and subsequently adding benzoyl peroxide as an initiator to prepare a main sizing agent polymer; and 2, mixing the main sizing agent polymer obtained in the step 1 with paraffin, polyvinylpyrrolidone, polyving alcohol and dodecyl sodium sulfonate together, so as to prepare the hot-melting sizing agent. The preparation method of the spinning hot-melting sizing agent for the polyester cotton is simple, and the prepared spinning hot-melting sizing agent has the characteristics of low hot-melting temperature and excellent water solubility.

Description

technical field [0001] The invention belongs to the technical field of textile slurry preparation methods, and in particular relates to a preparation method of textile hot-melt slurry for polyester and cotton. Background technique [0002] The main purpose of warp sizing is to improve the weavability of the warp so that it can withstand the strong mechanical action on the loom during weaving, that is, to ensure that the warp can be weaved smoothly on the loom and improve production efficiency. [0003] During the sizing process of the warp yarn, the size solution covers the surface of the yarn and penetrates into the inside of the yarn. After drying, a soft, tough and elastic uniform size film is formed on the surface of the warp yarn. The size film on the surface of the warp yarn improves the wear resistance. Due to the bonding effect of the size film, the free end of the fiber on the surface of the yarn is close to the yarn body, the hairiness is close to the yarn body, an...
