人造丝织物的仿真丝处理

Silk-like processing of rayon fabric

采用柠檬酸／柠檬酸钠溶液，对人造丝织物进行仿真丝处理。酸处理的优化工艺：pH值3．5～4．5，柠檬酸0．6～1．0g／L，柠檬酸钠0．4～0．8g/L，时间60-80min，温度80-100℃。碱处理：pH9-11，小苏打4—8g／L，砂洗粉3-6g／L，时间40-50min，温度40-50℃；柔软剂20-30g／L。大生产表明，处理后的人造丝织物仿真丝效果良好，质量稳定。

Silk-like finish of rayon fabric is carried out with citric acid/sodium citrate solution. The opti-mum acidifying process is pH value 3.5 - 4.5, citric acid 0.6 - 1.0 g/L, sodium citrate 0.4 - 0.8 g/L, treatingat 80 - 100℃ for 60 - 80 min; the optimum alkali process is pH value 9 - 11, sodium bicarbonate 4-8 g/L, sand washing powder 3 - 6 g/L, treating at 40 - 50 ℃ for 40 - 50 min; and softening with softener20 - 30 g/L. The practical application shows that the treated rayon fabric obtains silk-like performancewith stable quality.
