The Effect of Fiber Properties on the Characteristics of Spliced Yarns Part I: Prediction of Spliced Yarns Tensile Properties

In this study, the effects of splicing parameters, fiber and yarn properties on the tenacity and elongation of spliced yarns were investigated in detail. For this purpose, yarns from eight different cotton types, having three different counts (29.5, 19.7 and 14.8 tex) and three different twist coefficients (?tex 3653, ?tex 4038, ?tex 4423) were produced. Fiber properties measured using an Advanced Fiber Information System fiber tester were evaluated. Artificial neural network and response surface models were used to analyze spliced yarn tenacity and elongation as dependent variables. As independent variables, fiber properties together with the machine settings such as opening air, splicing air and splicing time, yarn twist and yarn count were chosen. As a result of the study, equations and neural network models that predict the tenacity and elongation of the spliced yarns were obtained. The obtained equations and models are statistically important and have high coefficient of multiple determination (R2). © 2010, SAGE Publications. All rights reserved

Parameters affecting the properties of the s pliced cotton/elastane blended core yarns

In this study, cotton/elastane blended core yarns in the yarn count of 20 tex with different twist factors and elastane linear densities were produced in order to determine the parameters which affect the properties of the splicing zone in winding process. After several trials, it is observed that the parameters affecting the breaking strength are splicing air pressure, splicing time, twist factor and elastane linear density for cotton/elastane yarns spliced with the elasto-splicer. The parameters which affect breaking elongation and the diameter of the spliced yarn are splicing air pressure and twist factor
