Prediction of warp and weft yarn crimp in cotton woven fabrics

The aim of this study was to develop statistical models for the prediction of warp and weft crimp percentage of cotton woven fabrics. The developed models are based on the empirical data obtained from carefully developed 60 fabric samples with different yarn linear densities, fabric densities, and weave designs. The predictability and accuracy of the developed models was assessed by correlation analysis of the predicted and actual crimp values of another set of eight fabric samples which was not used for the development of models. The results show fairly good capability and accuracy of the prediction models.

Influence of process variables on antimicrobial properties of cotton knitted fabrics

ABSTRACT

This work discusses the influence of process variables on antimicrobial properties of cotton single jersey knitted fabrics. The antimicrobial process variables are optimized based on the Box-Benken experimental design using design-expert software 8.0 to predict the optimum process parameter for achieving the required level of antimicrobial properties. The effects of process parameters such as yarn count, loop length, and finishing % of the zone of inhibition (ZOI) against the Escherichia coli and Staphylococcus aureus microbes on cotton knitted fabric have been carried out. Result shows that except yarn count other parameters are not significant toward the ZOI against microbes.     

Wicking and drying properties of conventional ring- and vortex-spun cotton yarns and fabrics

This study investigated the vertical wicking, water absorption and drying properties of vortex- and ring-spun combed cotton yarns and knitted fabrics comparatively. The yarns were produced in three different counts as 30 Ne, 40 Ne and 50 Ne. The experimental results revealed that vortex-spun yarns had lower yarn and fabric wicking and water absorption values than ring-spun yarns. In addition, it was observed that yarn type did not have a significant impact on the drying time of the fabrics.     

Impacts of yarn twist and staple length on UV protection of plain-knitted cotton fabrics

Yarn construction is an important attribute in knitting and end use performance of knitwear. Holistically, yarn construction affects fabric thickness and weight, and thereby influences ultraviolet (UV) protection of fabrics. Although impact of yarn construction on UV protection of fabrics is apparent, there appears to be limited research on it. This paper studied the UV protection of plain-knitted fabrics made of three types of ring-spun cotton yarns varying in yarn twist level and staple length. The results show that these yarn properties affect UV protection of fabrics differently before and after laundering. The modified low-twisted yarn possesses a bulky feature which creates a porous fabric structure for more ultraviolet radiation (UVR) transmission. The extra-long staple yarn offers uniform fabric appearance for higher UVR reflection. However, the regularity of yarn also restricts the fabric shrinkage in laundering and thus improvement in UV protection by shrinkage is not as obvious as that provided by the conventional short-staple yarn.
