Weibull Statistics and ANOVA Analysis of the Tensile Mechanical Characteristics of Chamaerops humilis Cellulose Fibers and Sustainable Twisted Yarns

Abstract

This study examines the tensile characteristics of Chamaerops humilis (ChF) fibers by testing them for the first time on samples with N?=?30 to 210. This study examined the quasi-static traction properties on 50?mm gauge length ChFs. Tensile tests with an average diameter of 12.381?�?1.23?mm and a twisting angle of 13� were conducted on 10 twisted ecological yarns to determine the effect of variation on plant fiber tensile properties for textile yarns. Furthermore, seven groups (N?=?30, 60, 90, 120, 150, 180, and 210) had 210 fibers analyzed. The dispersion was examined using variance analysis and Weibull distribution analysis because of the inherent heterogeneity in the mechanical properties of ChFs. The samples of Ch yarns exhibited a tensile stress ? of 68.52?�?7.89 MPa, ? of 7.14?�?0.32%, and E of 380.23?�?145.33 MPa. Tensile testing on ChFs revealed that N raises the fibers� ?, E, and ? values between 30 and 150 tests, while N?=?180 and 210 caused a drop. Also, The Kaplan-Meier estimator offers a better fit for the ChFs, according to the statistical study�s estimating techniques employing LS and ML approaches.
