Embodiment 1
[0025] Example 1: Finishing silk fabrics with silk fibroin nano-sol composite functional finishing agent
[0026] (1) Prepare A liquid: hydrolyze waste silk with sodium hydroxide to obtain silk fibroin hydrolyzate; wherein the concentration of sodium hydroxide is 2mol / L, the consumption of waste silk is 2g, the consumption of sodium hydroxide is 50ml, and the hydrolysis temperature is 70 ℃, the hydrolysis time is 2 hours.
[0027] (2) Preparation of liquid B: Take 3.5g of butyl titanate and 3ml of glacial acetic acid, add 10ml of deionized water and stir evenly with a magnetic stirrer, then add them dropwise to 40ml of 0.1mol / L hydrochloric acid solution, and at the same time After 30 minutes of magnetic stirring at constant temperature at 20°C, the temperature was raised to 40°C and continued to stir for 40 minutes to make it peptized, and then it was taken out and naturally cooled and aged to obtain nano-titanium dioxide sol;
[0028] (3) Preparation of silk fibroin nanosol...
