Abstract

The invention refers to a kind of compound lyosol fixing arrangement agent, a synthesizing method and the usage. The arrangement agent is made up of following products: (1) the silicon sol is made up of gamma-glycidol ether oxygen propyl trimethoxy-silane, water and hydrochloric acid, whose mol proportion is: 1:5-100:1í‡10 -5-1í‡10 -1; (2) the titanium sol is made up of titanic acid butyl ester, water and hydrochloric acid whose proportion is 1:0.1-10:10-200: 1í‡10 -4-1í‡10 -1; (3) the product is produced by mixing above mentioned silicon sol and titanium sol, the mol proportion of silicon and titanium is 1:0.05-1.0. The arrangement agent may form a mesh particle film on the surface of the fiber, realizes the color fixing aim.

Description

technical field [0001] The invention relates to a finishing agent for dyed fabrics, in particular to a composite hydrosol color-fixing finishing agent, a synthesis method and application thereof. Background technique [0002] The sol-gel method is a method in which organic or inorganic compounds of metals are hydrolyzed to form a sol, and then the sol is polymerized and gelled, and then the gel is dried and baked to become oxides or other solid compounds. As a material preparation method, the sol-gel method can be traced back to the middle of the 19th century. After more than 100 years of development, this method has been applied in many fields, and is currently mainly used in the preparation of glass, ultrafine powder and film. In the preparation process, high-temperature roasting at 300-800°C is adopted. When making the film, the smooth surface of glass, metal, plastic, etc. is used as the substrate for coating, and a network film is formed on the surface of the substrate...
