Abstract

The invention relates to a textile finishing agent preparation method, and belongs to the technical field of textile additives. Silk fibroin, maleic anhydride and tetrabutyl titanate serve as raw materials for preparing titanium dioxide, electrostatic attraction between the titanium dioxide and the silk fibroin is easily formed, imido combined hydrogen ions have positive charge, the surface of thesilk fibroin further contains rich hydroxy groups, the hydroxy groups and amino generated by auxiliary hydrolysis can form hydrogen bonds, and reaction activity is improved. The hydrogen bonds are inhybrid reaction with thiosemicarbazide, hydroxyethyl methylacrylate and the like, and the ultraviolet resistance and the antibacterial performance of a finishing agent are improved. The titanium dioxide is deposited on the surface of the silk fibroin and can be effectively combined with a fabric by the aid of rich active groups in the silk fibroin, the titanium dioxide and the fabric have good fusion properties by the aid of properties of the silk fibroin, the combination degree of the titanium dioxide and the fabric is further increased by an organic ligand formed on the surface of the titanium dioxide, and water resistance is enhanced under the action of aminopropyltriethoxysilane.

Description

Technical field [0001] The invention relates to a preparation method of a fabric finishing agent, belonging to the technical field of textile additives. Background technique [0002] Ultraviolet rays are prone to adverse effects on textiles. After silk is irradiated by ultraviolet, the C-N bond of the peptide bond group in the main chain of the molecular chain and the side group is broken, releasing CO and N 2 Wait for the gas to finally decompose into amino acids. High-performance fibers will also experience varying degrees of performance degradation under ultraviolet radiation. For example, after polyparaphenylene benzodioxazole (PBO) fibers are irradiated with ultraviolet rays, their internal carbon atoms are oxidized to CO and CO 2 And so on, and CO can further accelerate oxidation. At the same time, the hydrogen atoms in the polymer are oxidized to -COOH, and then the bimolecular decomposes to generate free radicals, attack PBO macromolecules, destroy the chemical structure...
