Abstract

The invention discloses a method for carrying out modification on real-silk fabrics by using butyl titanate, and the method comprises the following steps: in a bath ratio of 1:(20-50), placing a real-silk fabric to be modified in a mixed solution to process for 10 minutes under the conditions that the temperature is 90 DEG C and the pH value is 10, wherein the mixed solution is prepared by dissolving soda ash (1.5 g / L) and sodium silicate (1 g / L) into water; then washing the real-silk fabric to be modified for 10 minutes by using hot water at a temperature of 60 DEG C, then rinsing the real-silk fabric to be modified for 10 minutes by using cold water, and drying the real-silk fabric to be modified beside or over a fire; carrying out modification reaction on the real-silk fabric subjected to processing; in a bath ratio of 1:(30-50), washing the real-silk fabric subjected to modification reaction for 10-30 minutes by using a washing solution at a temperature of 40-60 DEG C; and then repeatedly washing the real-silk fabric by using cold water, and drying the real-silk fabric beside or over a fire or in the air, thereby obtaining the modified real-silk fabric. The modification method disclosed by the invention is material-saving, simple and convenient in operation and less in loss of fabric strength. The modified real-silk fabric after being washed 30 times still has the advantages of excellent uvioresistant and antibacterial properties.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and relates to a method for modifying real silk fabrics, in particular to a method for modifying real silk fabrics by using butyl titanate. Background technique [0002] Nano-titanium dioxide powder is an oxide wide-gap semiconductor material that has attracted much attention today. It has excellent anti-ultraviolet and antibacterial functions. Combining it with ordinary textile materials can protect people from ultraviolet rays and reduce the spread of diseases. Therefore, it has Very important practical application value and development prospect. At present, the methods for preparing nano-titanium dioxide mainly include sol-gel method, uniform precipitation method, microemulsion method and hydrothermal method, etc. Among them, the hydrothermal method is environmentally friendly and high in purity, and the prepared nanoparticles are uniform and well dispersed without high te...
