丝素整理剂用于棉织物防皱整理的研究

Study on anti-wrinkle finishing of cotton fabric with silk fibroin

分别研究丝素、柠檬酸、丝素/柠檬酸复配整理棉织物后,对棉织物的折皱回复角、白度、断裂强力的影响。采用丝素与柠檬酸复配,对棉织物进行防皱整理,结果表明,丝素/柠檬酸复合整理棉织物,具有良好的协同增效作用,既克服了柠檬酸整理的泛黄现象,又可以大大提高棉织物的防皱性能。分别选用丝素浓度、丝素水解时间、柠檬酸用量、pH值设计L16(44)正交试验,结果显示,丝素浓度6%,柠檬酸用量30 g.L-1,丝素水解时间2 h,pH值6时对棉织物的整理效果最好。

We discussed the wrinkle recovery angle,whiteness,breaking strength of cotton fabric after hav-ing been finished by fibroin,citric acid,fibroin/ citric acid.We finished the cotton fabric with fibroin/citric acid complex,and found that the silk/cotton,citric acid compound treatment showed good synergistic coordination,which not only overcame the shortcoming of turning-yellow with citric acid treatment,but also improved the anti-wrinkle properties of cotton fabric.Four factors such as fibroin concentration,fibroin hydrolysis time,citric acid dosage,pH value,were chosen to design L16（44）orthogonal experiment.The results suggest that treated with fibroin 6%,citric acid 30 g·L-1,fibroin hydrolysis for 2 h,pH 6,cotton fabric could get best finishing effect.
