Abstract

In spinning production, the carding process has a great influence on the sliver’s quality, as well as the resulting yarn’s quality properties. This research work was carried out to substantiate the spinning yarn’s quality by changing the carding release speed. Changes in the yarn’s quality properties obtained at different carding speeds were analyzed using laboratory equipment Uster® system. The study’s main aim is to determine the optimal carding speed required to obtain low linear density yarn. Yarn number Ne 40/1 (14.5 tex) was obtained on a Zinser® ring spinning machine As a result of the study, it was found that when measuring the effect of spreading release speed on yarn inhomogeneity with increasing release speed from 180 m/min to 210 m/min with lower value of yarn inhomogeneity, with increasing spreading release speed from 180 to 210 m/min there is a continuous increase in yarn defects in spinning yarn. In the study, with the increase in release drum speed, the spinning yarn strength decreased from 16.8 cN/tex to 16.0 cN/tex. There was an increase in discharge speed from 180 to 210 m/min from 4.2% to 4.8% with low yarn pile. It was found that yarn elongation decreased from 5.42% to 5.25% due to increase in distributed release speed.
