Abstract

The invention provides a method for finishing wool fabric by compositing chitosan / TiO2, which comprises the following steps: A)pretreating fabric; B)preparing composite finishing liquor, taking butyl titanate and dissolving in ethanol, adding diethanolamine, uniformly stirring and adding mixed liquor mixed by ethanol and water, heating, stirring under a backflow state to form nano TiO2 sol; adding chitosan, citric acid and sodium hypophosphate in the nano TiO2 sol, uniformly stirring to obtain the composite finishing liquor; C)finishing wool fabric, placing wool fabric in the composite finishing liquor, dipping and padding twice, wherein mangle expression is 85% and padding temperature is 50-65%; D)predrying; E)baking; F)washing; and G)drying. According to the finishing method, chitosan and nano TiO2 sol are employed as the composite finishing liquor, the finished wool fabric has good antibiosis, shrinkproof, ultraviolet resistance and anti-insolation performances; the finishing method generates no pollution on human body and environment, and the finished wool fabric has good hand feeling.

Description

technical field [0001] The present invention relates to a kind of finishing method of wool fabric, especially relate to a kind of using chitosan / TiO 2 A method for compound finishing wool fabric. Background technique [0002] With the widespread use of light and thin fabrics in summer, the deodorization, antibacterial, anti-ultraviolet and sun resistance properties of wool fabrics have become the concerns of textile workers. After long-term ultraviolet irradiation on wool fabric, the dye molecules on the fabric will absorb photons and become excited states, which will cause the dye to undergo photochemical reactions and reduce the light fastness of the fabric. Become an important factor affecting product quality and grade. [0003] Nano-TiO 2 With its excellent chemical stability, high efficiency, selectivity, non-dissolvability, safety, low price, and non-polluting advantages, it is recognized as one of the hot spots in the application research of high-tech textiles....
