An approach to investigate the spinnability of fine count yarns on vortex spinning system




File Size: 3.95 Mb

Description
In this study, the possibilities of fine count yarn spinning on vortex spinning system was investigated, and the factors influencing the fine count yarn spinning on the system were identified in relation to yarn structural and physical properties.

For this purpose, experiments were carried out to compare the properties of ring, open-end rotor and vortex spun yarns in three counts with special reference to cellulosic fibers including cotton, viscose and 50/50 cotton-Modal blend. Yarn samples were converted into single jersey knitted fabrics to determine the physical performances of yarns in knitted form. In this way, the position of vortex spun yarns among ring and open-end rotor spun yarns was determined on the basis of yarn physical properties and their performances on knitted fabrics.

In the following section, the experiments were conducted to examine the effects of intermediate draft, total draft and yarn delivery speed on viscose vortex spun yarns in order to identify the drafting conditions before proceeding to the investigation of possibilities of extending vortex spinning to finer yarns and to estimate the spinning limits.
