剑麻纤维的脱胶工艺及可纺性研究. (Chinese)

Degumming Process and Spinnability of Sisal Fiber. (English)

The spinnability of sisal fiber after degumming process was discussed. Chemical degumming method was used for sisal fiber treatment. The influences of hydrogen peroxide concentration, hydrogen peroxide treatment temperature & time, sulfuric acid and sodium hydroxide treatment concentration & time on sisal fiber degumming process were analyzed with residual gum content, fiber diameter and breaking strength. Sisal blended yarn was spun. The test results showed that the optimized treatment process was 1:50 as the bath ratio,1 h treatment with mass fraction 20 g/L of 30% hydrogen peroxide at 60 °C ,24 h treatment with 8% mass fraction sulfuric acid solution at room temperature and 2 h treatment with 5 g/L sodium hydroxide at 90 °C.The residual gum content of obtained sisal fibers was 5.45%,fiber diameter and breaking strength was 84.58 µm and 175.55 cN respectively. It is considered that the sisal fiber after degumming process has a certain spinnability. It can be used to spin sisal blended yarn. [ABSTRACT FROM AUTHOR]

探讨脱胶后剑麻纤维的可纺性能。采用化学脱胶法对剑麻进行处理，以残胶率、纤维直径和断裂 强力为指标，分析了双氧水浓度、双氧水处理温度和时间、硫酸与氢氧化钠处理浓度和时间对剑麻脱胶工艺的影 响，并纺制了剑麻混纺纱。试验结果表明：最佳处理工艺为浴比1∶50，20 g/L 的质量分数30% 双氧水于60 ℃下 处理1 h，质量分数8% 硫酸溶液于常温下处理24 h，5 g/L 氢氧化钠于90 ℃下处理2 h，所得剑麻纤维残胶率为 5.45%，纤维直径和断裂强力分别为84.58 μm、175.55 cN。认为：脱胶后的剑麻纤维具有一定的可纺性，可用于 纺制剑麻混纺纱.
