生丝强伸力单丝检测与复丝检测结果的差异及相关性分析

The diversity and correlation analysis of monofilament test results and multifilament test results of raw silk tensility

文章在同台设备上开展了100批生丝强伸力的单丝检测与复丝检测比对试验,并运用数理模型进行检测结果分析。结果表明,单丝断裂强度明显高于复丝,断裂伸长率低于复丝。单丝检测对生丝强伸力质量波动反应更灵敏,可建立包括变异系数在内的单丝强伸力检测质量考核体系。单、复丝断裂强度呈非线性关系,断裂伸长率呈线性关系,探索了通过单、复丝各项指标之间的线性关系推算出单丝强伸力质量指标考核值的可行性。

100 batches of raw silk were compared on the same equipment in the aspects of tensility of monofilament test and multifilament test.Then,the mathematical model was applied to analyze the test results.The results show that,the breaking strength of monofilament is obviously higher than that of the multifilament,but the breaking elongation of monofilament is less than that of the multifilament.Monofilament test is more sensitive to quality fluctuation of tensility.Quality assessment system of tensility of monofilament test should be built,including variable coefficient.The breaking strength of monofilament and multifilament presents non linear relationship.And their breaking elongation presents linear relation.The linear relation among various indexes of monofilament and multifilament was explored,and the feasibility of tensility quality index assessment value of monofilament was calculated.
