摘要
以苎麻纤维为试验原料,设计正交试验和单因素试验,探讨苎麻纤维碱-尿素改性工艺中Na OH质量分数、尿素质量分数、试验时间和浴比对纤维弯曲模量的影响。通过对测试数据进行分析,结果显示:正交试验得到碱-尿素改性工艺中的影响因素对纤维弯曲模量的影响显著性不同,其中Na OH质量分数的影响显著性最大,浴比的影响显著性最小。单因素试验得到碱-尿素改性工艺中的影响因素中苎麻纤维弯曲模量的影响规律也有差异,其中纤维的弯曲模量随着Na OH质量分数、尿素质量分数和试验时间的增加而逐渐减小,但是纤维的弯曲模量随着浴比增加却呈现增大的趋势。
The effects of NaOH concentration, urea amount, testing time and bath ratio on bending modulus of ramie fiber were studied by orthogonal test and single factor test. Orthogonal test results showed that, the factors affecting the fiber bending modulus were significantly different in alkali-urea modification process, NaoH concentration had the highest significant effect but bath ratio had the lowest effect. Single factor test results showed that, the bending modulus of ramie fiber was decreased with the increase of NaoH concentration, urea amount and test time, but increased with the increase of bath ratio.
