Abstract

The invention discloses a modifying and dyeing method for a polyamide textile by using tetrabutyl titanate and reactive dye, comprising the following steps of: repeatedly washing the polyamide textile in ultrasonic oscillation at the temperature of 60-90 DEG C by respectively using deionized water and absolute ethyl alcohol with mass concentration of 95%, and drying; then, processing the polyamide textile with the tetrabutyl titanate and the reactive dye; finally, washing the polyamide textile for 10-30 minutes with a cleaning solution at the temperature of 95 DEG C according to a bath ratio of 1:30-50, repeatedly washing the polyamide textile by respectively using hot water and cool water, and drying or naturally airing the polyamide textile to get the modified and dyed polyamide textile. With the method provided by the invention, production procedures are greatly simplified, material cost is saved, and additional value of products is improved. The modified and dyed polyamide textilehas excellent color fastness to dry and wet frictions, scrubbing and lighting; and polyamide textile has higher dye uptake and is dyed uniformly, after being washed for 30 times, the dyed polyamide textile still has better antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and relates to a method for modifying and dyeing nylon fabric, in particular to a method for modifying and dyeing nylon fabric by using tetrabutyl titanate and reactive dyes. Background technique [0002] Nano-titanium dioxide is a very important inorganic semiconductor material. Its unique ultraviolet shielding ability, photocatalytic activity and color effect make it popular as soon as it comes out. It has broad applications in sun protection, sterilization, wastewater treatment, environmental protection and automobile industry application prospects. Fabrics with multiple functions can be prepared by utilizing the characteristics of nano-titanium dioxide such as high temperature resistance, refractory decomposition, non-toxicity, long-lasting function, and good compatibility with polymers. The preparation methods of nano titanium dioxide mainly include gas phase method, l...
