摘要
以硫代硫酸钠和过硫酸铵的氧化还原体系为引发剂,丙烯酸为单体,对亚麻短纤维进行接枝改性,并用红外光谱进行了表征。研究反应温度、时间、引发剂用量及单体浓度对亚麻接枝率及单体接枝效率的影响。接枝后亚麻短纤维的分裂度提高204Nm,断裂强度降低1.27cN/tex。性能测试结果表明:丙烯酸接枝改性亚麻短纤维工艺对纤维损伤小,改善了亚麻短纤维的可纺性,纺纱性能提高。
Short-staple flax was graft modified by redox system consisted of sodium thiosulphate and ammonium persulfate as initiator and acrylic as monomer. The modified flax was characterized by infrared spectrum. Influences of reaction temperature, time, dosage of initiator and monomer concentration on grafting rate of flax and grafting efficiency of monomer were discussed. The splitting degree of the grafted fiber is improved by 204 Nm, and breaking strength is reduced by 1.27 cN/tex. The process of the graft modification with acrylic is demonstrated to be slightly harmful to short-staple flax via performance tests. This process is also able to enhance the spinnability of the short-staple flax, leading to the improvement of the spinning performance.
