高温裂解亚麻短纤维工艺及性能研究

Study on process and spinnability of flax short fiber decomposed under high temperature

用碳酸钠对亚麻短纤维进行高温裂解处理,分析碳酸钠用量对亚麻短纤维分裂度、失重率、断裂强度、伸长率指标的影响.结果表明:采用碳酸钠及相应助剂对亚麻短纤维进行高温裂解工艺处理,可以明显去除果胶和木质素,分裂度由未处理的237 Nm提高到1 598 Nm,改善了亚麻短纤维的可纺性能.

The flax short fiber is decomposed under high tempreture with NaC03, and the effect of consumption of NaCO3 split degree, reduction rate, strength and tensile stretch of flax short fiber. The results indicate that dealing the flax stable with the process of high temperature decomposition using the sodium carbonate and relevant auxiliary, the pectin and lignin pigments can be removed obviously and the split degree can increase from 237 Nm untreat- ed up to 1 598 Nm, and the spinnability is improved, which provide theory foundation to the flax factory on spin- ning procedure.
