摘要
为提高尼龙织物的反应性,采用氯乙酸对尼龙织物进行羧甲基化改性。探讨了氯乙酸和异丙醇用量、反应温度和反应时间对尼龙羧甲基化程度的影响。以改性后羧甲基的取代度、增重率和阻燃整理后的氧指数评价尼龙织物的改性程度,采用傅里叶变换红外光谱和扫描电镜分析改性尼龙织物的结构及表面形态。尼龙织物羧甲基改性的优化工艺为:氯乙酸质量分数5%,异丙醇用量90 mL,60℃反应90 min,羧甲基化对尼龙织物物理性能的影响较小。
In order to improve the reactivity of nylon fabric, chloroacetic acid is used to modify the nylon fabric by carboxymethylation. The effects of the amounts of chloroacetic acid and isopropanol, reaction temperature and reaction time on the carboxymethylation degree of nylon are discussed. The modification degree of nylon fabric is evaluated by substitution degree, the weight gain rate and the LOI of fabric after the flame-retardant finishing. The structure and surface morphology of the modified nylon fabric are analyzed by FT-IR and SEM. The optimization of carboxymethylated modification of nylon fabric is： 5% of chloroacetic acid, isopropanol 90 mL, reaction at 60 ℃ for 90 min, carboxymethylation has little effect on the physical properties of nylon fabric.
