| 中文摘要: |
| 分析了过氧乙酸在苎麻预处理工艺中的应用,探讨了过氧乙酸用量,温度,时间和pH值4个因素对过氧乙酸预处理效果的影响.根据苎麻精干麻的断裂强度、断裂伸长率、断裂比功、SEM和XRD等物理机械性能和表面形态的测试,对比分析了过氧乙酸-氢氧化钠脱胶工艺和传统化学脱胶工艺的精干麻性能.实验表明,当过氧乙酸浓度为2.5％,温度为50℃,pH值为8.0,时间为2h,苎麻精干麻的断裂强度可以达到最佳. |

| The application of peracetic acid on the pretreatment process of the ramie degumming was analyzed in this paper.The four factors the dosage of peracetic acid,temperature,time and pH value on the effect of pretreatment effect were discussed.According to the test results of the physical and mechanical properties and surface morphology,such as tenacity,breaking elongation,specific work of rupture,SEM and XRD and so on,the property of degummed fiber treated by peracetic acid-sodium hydroxide degumming process and traditional chemical degumming process respectively was compared and analyzed.The experimental results showed that when the concentration of acetic acid peroxide was 2.5%,the temperature was 50 ℃,pH value of 8.0,time was 2 hours,the tenacity of the degummed fiber was the best. |
