Selecting Processing Parameters That Influence the Strength of Rotor Spun Yarn Formed on the SDL Quickspin System

摘要

The SDL Quickspin System is designed to allow spinners to quickly evaluate raw cotton and observe its effects on the resulting yarn quality and spinning performance. This work reports on the effects of several critical processing parameters of the Quickspin System, including navel type, rotor speed, and sliver linear density, on the tenacity of Quickspin yarn. The results show that there are several significant effects of these critical parameters and their interactions on the tenacity of Quickspin yarn. The navel type exerts significant effects on the tenacity of Quickspin yarn. A higher tenacity, finer Quickspin yarn can be obtained at a lower rotor speed. Reducing the linear density of sliver is beneficial to the tenacity of Quickspin yarn. These findings confirm that the parameter settings of the Quickspin System closely match those of conventional rotor spinning adopted in normal yarn production. From this investigation of the interactions of the critical parameters, optimum settings of the Quickspin System can be obtained and used as a reference for spinners.
