Effect of silk yarn parameters on the liquid transport considering yarn interlacing

Abstract

Wetting and wicking are among the essential behaviors of fabric. Woven fabric is interwoven by the warp and weft yarn, and it can be considered as a yarn network. To clarify the wicking phenomenon of woven fabric and simulate its water transport, the wicking behaviors in the vertical and horizontal directions of six yarn samples were examined. The moisture movement of these interlacing silk yarns was clarified. The wicking behaviors of the silk yarn were found to increase at the first initial stage, and decrease with time until the yarn is saturated. The wicking length of the vertical direction revealed that the fiber and void areas in the silk yarn have an essential effect on water transport. Further, the wicking relationship between single and interlaced yarns was also discussed. The good relationship between the wicking length of single and interlaced yarns shows the possibility of predicting the wicking ability of the textile through the initial wicking ability of the single yarn in the future.
