竹纤维家纺面料的防缩防皱整理

Shrink-Proof and Crease-Proof Finishing of Bamboo Home Textile Fabric

本课题采用超低甲醛树脂对竹纤维家纺面料进行防缩防皱整理,探讨了树脂用量、催化剂用量、pH、焙烘温度及时间对竹纤维家纺面料性能的影响。在单因素实验的基础上,通过正交实验,优化得出的整理工艺为:树脂125g/L,六水合氯化镁15g/L,整理液pH为4.5,焙烘温度145℃,焙烘时间2min。整理织物的折皱回复角提高了80°,缩水率降至3%以下,甲醛质量分数低于75mg/kg。

Anti-shrink and anti-wrinkle finishing of bamboo home textile fabric was carried out with ultra-low formaldehyde-free resin. The influences of dosage of resin finishing agent and catalyst, pH value, curing time and temperature on the performances of bamboo home textile fabric were discussed. On the basis of single factor test, the finishing process was optimized by orthogonal test method. The results showed that the optimum finishing process was resin 125 g/L, MgCl2~6H2O 15 g/L, pH value 4.5, curing at 145 ℃ for 2 min. The crease recovery angle of finished fabric increased by 80°, the washing shrinkage decreased to below 3% and the formaldehyde content was lower than 75mg/kg.
