Studying the Mechanical Properties of Jute/Cotton Blended Yarns Using the Weibull Model

The phenomenon of a material failure varies with its gauge length in use. In the present study, the breaking strengths of J30/C70 and J55/C45 blended yarns spun by the ring spinning technology were investigated with the employment of the equations derived from the Weibull theory. The four probability estimators of the Weibull distribution were also evaluated. The results showed that the estimator （2a） was acceptable for calculating the Weibull modulus of the jute/cotton blended yarns. With the exception of breaking strength of the J30/C70 at the gauge length of 200 ram, the breaking strengths of both blended yarn could be predicted accurately by the Eqs. （9） or （10） in this paper.

2000年棉花及纺织品进出口形势分析

在经历了亚洲金融危机的冲击之后,2000年彻底扭转了自1998年以来我国出口增速下滑的趋势,全国外贸出口和纺织品出口双双创历史新高。据海关统计,2000年我国纺织品服装进出口总值达700.6亿美元,比上年上升20.4％,占全国外贸进出口总值的14.8％。其中,进口总值为168.1亿美元,比上年上升19.3％,占全国外贸进口总值的7.5％;出口总值532.4亿美元,比上年上升20.7％,占全国外贸出口总值的21.4％。
