Technology on Fibroin Finishing of Cotton Fabrics

The change of structure and the properties of cotton fabric was studied on the condition of fibroin finishing hydrolysis time and concentration of aqueous slkali.The breaking strength and breaking elongation maintained stabe with the prolonging of hydrolysis time,but decreased distinctly at 120 min.The crease recovery and white content increased with prolonging of hydrolysis time,but reduced distinctly at 120 min.The breaking strength,breaking elongation,crease recovery and white content increased with the rise of concentration of aqueous slkali,but decreased distinctly in 17%.Research shows that after alkali treatment and processing of silk fibroin solution crystal structure of cotton fibre is breaked,accessibility and bridging property are raised.After fibroin finishing,the cotton fabrics effects are the best at 120 min and 17%.
