Embodiment Construction

[0030] (1) Add ethyl orthosilicate (0% to 50%), γ-glycidyl etheroxypropyl trimethoxysilane (0.1% to 50%), and ethanol (30% to 90%) to the three necks in sequence. In the bottle, stir on the stirrer to make them mix evenly, and the stirring speed is 200-400 rpm; add the hydrochloric acid (0.005-1.0mol / l) solution into the mixed solution dropwise under stirring; stir at room temperature for 24 Hour.

[0031] (2) Dip and roll the dyed fabric twice in the finishing solution (pressure 2-3kg / cm2) 2 ), and then dried in a blast oven at 100-180°C for several minutes.

[0032] (3) Carry out the fastness test to the dyed fabric, specifically as follows:

[0033] ① Soaping fastness test: Prepare 4g / L soaping liquid, sew a 4cm*10cm cloth sample with white cloth of the same size, soak in 1:50 soap liquid, put it into the soaping fastness tester, After soaping at 40°C for 30 minutes, take it out, wash the cloth sample with distilled water, remove the stitches, and dry it. Then test it o...

Abstract

The present invention belongs to the field of chemical technology and is a kind of sol-gel color fixing method. Reagent capable of producing chemical combination with fabric fiber is selected as material for sol finishing liquid to finish fabric at 100-180 deg.C. Thn and transparent complicated network film is formed on the inner and outer surface of fiber to fix the dye on the fabric and to raise the color fastness of fabric.

Description

Technical field: [0001] The invention belongs to the technical field of chemical industry. Specifically relates to a sol-gel color fixing method. Background technique: [0002] The basic principle of sol-gel technology is to directly form a metal alkoxide or inorganic salt by hydrolysis or degelation to form a sol, then polymerize and gel the solute, then dry and bake the gel to remove organic components, and finally obtain Inorganic materials. At present, it is mainly used in the preparation of glass, ultra-fine powder and thin film. It needs to be fired at a high temperature of 300-800 ° C. When making the film, the smooth surface of glass, metal, plastic, etc. is used as the substrate for coating, and a continuous film is formed on the surface of the substrate. , The combination between the membrane and the carrier is by van der Waals force, and there is no chemical combination. It is unrealistic to use such a process on textiles, because textiles cannot withstand high...
