棉织物的免烫整理

为消除棉织物免烫整理后的甲醛影响,针对棉织物进行了多元羧酸整理的研究,以降低高温焙烘时织物的泛黄现象,减少整理后废水中的含磷量。以柠檬酸与酒石酸的混合酸作为棉织物免烫整理剂,研究了柠檬酸与酒石酸物质的量比、焙烘工艺条件、催化剂种类及质量浓度、添加剂质量浓度等对织物整理效果的影响。结果表明,柠檬酸与酒石酸物质的量比为1∶1,焙烘温度为180℃,焙烘时间为2 min,纳米二氧化硅质量浓度为2 g/L,次磷酸钠质量浓度为20 g/L,柔软剂LD-5030质量浓度为20 g/L时,织物整理效果较佳。

Durable press finishing of cotton fabrics

Polycarboxylic acid finishing of cotton fabrics was studied. In order to eliminate the effect of formaldehyde released by DP finishing, and reduce the yellowness caused by high temperature curing and phosphorus content in wastewater, DP finishing of cotton fabrics was performed with mixed citric acid and tartaric acid as finishing agent, and the effects of mass fraction of citric acid and tartaric acid, curing conditions, kinds and concentration of catalyst, and mass concentration of additives on the treatment were investigated. The experiment demonstrated that the optimum finishing results are obtained when mass fraction of citric acid to tartaric acid is 1:1, curing temperature is 180 ℃, curing time is 2 min, mass concentration of nanosilica is 2g/L, mass concentration of sodium hypophosphite is 20g/L, and mass concentration of softener LD-5030 is 20g/L.
