苎麻单纤维断裂强力等速伸长测定法研究

摘要

阐述了等速伸长法测定纤维断裂强力的先进性，同时系统研究了测定根数、拉伸隔距、拉伸速率等因素对苎麻单纤维断裂强力试验结果的影响。其结果为采用等速伸长法准确测定苎麻单纤维断裂强力奠定了基础。%This paper describes the advancement of testing fiber breaking strength under the condi-tion of constant extension rate,and the effect of sample numbers,extension gap and extension rate on breaking strength of ramie single fiber was studied systematically.These results would lay a foundation for accurate determination of breaking strength of ramie single fiber under constant extension rate.
