“…The load at break and extension at break of nanofiber webs show an increasing trend with cross‐head speed from 5 to 12 mm/min, followed by a decreasing trend with cross‐head speed from 12 to 18 mm/min. The increase in load at break and extension at break can be accounted for by two factors: the realignment of fibers during stress loading and the percentage of ruptured fibers . The increasing of interfiber pressure leads to an increasing of frictional resistance, which results in an increase of load at break and extension at break .…”

The increasing of interfiber pressure leads to an increasing of frictional resistance, which results in an increase of load at break and extension at break . However, there is insufficient time for realignment of fibers with cross‐head speed between 12 and 18 mm/min, which explains the decline.…”

A tensile properties testing study was conducted to understand the influence of thickness, cross-head speed (speed of testing), gauge length (GL; specimen test length), and sample shape on important tensile properties of polyvinyl alcohol (PVA) nanofiber webs. The effects of each testing parameter on load at break, extension at break, Young's modulus, and tensile stress-strain curve of PVA nanofiber webs are analyzed. The Welch two sample t-tests show the significant difference among tested data. Using interaction plots, two-way analysis of variance, and margin mean plots, the interaction effects among testing parameters have been analyzed. Of all the factors, cross-head speed, the interaction among GL, and sample thickness (GL: Thickness) and the interaction among GL, testing speed and sample thickness (GL: Speed: Thickness) have significant influence on the tensile properties of PVA nanofiber webs. Moreover, the hypothesized model of mechanism of tensile strain-stress curve of PVA nanofiber webs has been proposed. Based on the model, the tensile strain-stress curve can be split into three stages: linear elastic, partial break up, and complete breakage. This study will provide a better understanding of tensile testing parameters' effects and their interaction effects on the tensile properties of nanowebs.

“…RKM is an abbreviation of resistance per kilometre which is related to yarn tenacity. Tensile behaviour depends on the characteristics and structural arrangement of constituent fibres (Das, 2010; Majumdar and Sengupta, 2003). When RKM results of the samples were observed (Figure 10), it is generally observed that RKM results do not fluctuate in a wide range.…”

PurposeThe paper aims to provide an investigation about the effect of some selected production parameters such as core yarn type, sheath sliver type and total yarn count factors on core spun vortex yarns' evenness, imperfection and tensile properties. Hence it is aimed to contribute to the literature in vortex spinning where there are limited works related to core-spun vortex spinning.Design/methodology/approachThe paper evaluates the effect of core yarn type, sheath sliver type and total yarn count factors on yarn evenness, imperfections, hairiness and tensile properties. Completely randomised three-factor analysis of variance (ANOVA) was conducted in order to evaluate the effect of core yarn type, sheath sliver type and linear yarn density on core spun vortex yarns' evenness, imperfection and tensile properties at significance level of 0.05. SNK tests were also performed for observing the means of each parameter. Correlation analysis was also conducted to reveal some relationships between yarn evenness and yarn tensile properties.FindingsIn this paper, significant factors related to some production parameters affecting the core-spun vortex yarns' evenness, imperfection, hairiness and tensile properties were found.Originality/valueThere are limited works related to effect of selected production parameters on yarn evenness, Imperfections and Tensile Properties of Hybrid Vortex Yarns.

“…The tensile properties of yarn are accepted as one of the most important parameters for assessment of yarn quality. The tensile properties decide the performance of post spinning operations; warping, weaving and knitting and the properties of the final textile structure; hence its accurate technical evaluation carries much importance in industrial applications [16] [17]. Tenacity, tensile strength, elongation, and quality ratio are important measuring parameters of tensile properties of yarn.…”

This work reports the successful outcomes to process the polyester, acrylic and wool fiber along with jute fiber exclusively using existing jute processing machineries for manufacturing the 241 tex jute blended yarn. The blending was performed at feeding stage of breaker carding machine and blending ratio of jute and polyester/acrylic/wool fibers is 80:20. Manufacturing of jute blended yarns will create a new opportunity for extending the uses of jute fibers in value added jute products. The present work is concerned with the investigation of physical properties such as tenacity, elongation % at break, quality ratio, unevenness, imperfections (thick, thin & neps) and hairiness of manufactured jute blended yarns. The jute-polyester (80/20) blended yarn shows the higher strength and more evenness compared to jute-acrylic (80/20), jute-wool (80/20) blended and 100% jute yarn.
