“…They also attempted to simulate the strength of fiber assemblies in yarn. In 2007, G. Yan and C. Yu attempted to explain the comprehensive influence of fiber length and fineness on yarn strength, and they offered a plausible method to estimate the critical length represented by Zeidman (Yan & Yu, 2007). W. B. Faulkner and associates conducted a study on the relationships between ring-spun yarn quality and fiber in 2012 and discovered that yarn work-to-break was highly correlated with fiber bundle elongation(Faulkner, 2012).…”

Fiber length is one of the major fiber properties that influence yarn strength, evenness, product handle, product luster, and yarn hairiness. To assure yarn quality, fiber passes through a number of machinery during the spinning process, where it is subjected to various sorts of action that modifies the fiber length. As different process parameters are chosen based on fiber length, fiber length analysis throughout the spinning process will benefit in the adjustment of machine parameters to produce better quality yarn. This study will reveal the chronological change in average fiber length at different stages of the carded ring spinning process, as well as a correlation analysis of length change among different phases, using correlation and regression methods. For five distinct mixing samples, raw cotton, card mat, carded sliver, breaker drawn sliver, finisher drawn sliver, roving, and yarn (pneumafil) were examined at each stage from raw cotton to ring frame. Then, using USTER AFIS PRO, all of the samples were numerically evaluated and statistically analyzed using Microsoft Excel 2016. A positive correlation between fiber length changes at several phases was observed in the experiment, with average fiber length increasing in carding, breaker drawing, finisher drawing, and simplex but decreasing in card mat and ring.

“…Yarn strength has been an important subject of research in the textile industry. 1–3 The factors influencing yarn strength, such as fiber properties, 4,5 yarn structure, 6 and testing parameters, 7 have been systematically investigated. Previously, scholars attempted to predict the overall yarn strength by analyzing the basic yarn parameters, in order to guide the processing of related products.…”

This study examined the superiority of the strength of compact-Siro spun yarn. First, the strength properties of four types of yarn-ring, compact, Siro, and compact-Siro spun yarn-were compared based on an experiment with 9.7 tex and 14.6 tex polyester yarns. Yarn unevenness and compactness were analyzed in terms of their influence on yarn strength. It was determined that compact spinning enhanced the strength distribution by improving the overall yarn compactness. Siro spinning significantly increased the minimum yarn strength by reducing unevenness. Furthermore, compact-Siro spun yarn, which incorporates the advantages of both compact and Siro, remarkably improved the yarn strength distribution. These results were verified in the first part of the experiment. Finally, the four types of yarn were applied in the same weaving process. The results indicated that the efficiency of weaving with compact-Siro pure polyester yarn was higher than that of other methods by 3%-6%, thereby confirming the superior productivity of the method.

“…Afterwards, the fiber length and its distribution were taken into consideration to calculate the sliver irregularity in the short-term based on the model of fiber arrangement in the sliver. 6,18,19 Besides, the irregularity of the total weight of fibers within each sliver subsection was obtained by applying the fiber fineness distribution in the sliver simulation. 7,20 Notwithstanding all this, the assumption that fibers were completely separated and straight along the sliver axis in these methods leads to far fewer simulated sliver irregularities than actual ones.…”

The fiber straightness and separation degree have the important influences on sliver properties. In this work, an innovative model of the fiber configuration considering straightness was presented and optimized by taking the fiber separation degree into account. The new developed model could simulate fiber assemblies and all kinds of separated fibers, including hooked fibers and straight fibers. Furthermore, some thin and thick segments were presented in the optimized simulated sliver with consideration of the fiber separation degree, and the simulated sliver irregularities were close to the actual ones. The relative errors between tested sliver irregularities and simulated ones were reduced from around 80% to less than 30%. Besides, the influence of each fiber parameter on the sliver irregularity could be drawn from the novel model of fiber configuration in the sliver, which verified the necessity of the applications of the straightness and separation degree. Therefore, it could be concluded that the introduction of the fiber straightness and the consideration of the fiber separation degree made more accurate and reasonable simulation of the fiber configuration in the sliver. Moreover, the straightening process of the hooked fibers and the random combination between thick fragments and thin fragments during the drawing simulation could be realized based on this model in the future.
