The influence of increasing the productivity of the carding machine on the quality indicators of the card sliver

Abstract

The paper investigated the influence of the rotation frequency of the take-up, main and doffing drums of the C60 carding machine from RIETER on the quality indicators of the card sliver. The raw material used was medium-fiber cotton with a fiber length of 26.5-28 mm. The experimental study was carried out with changing speed modes: rotation frequency of the main drum from 451 to 520 rpm, of the take-up drum from 1018 to 1400 rpm, of the doffing drum from 62 up to 72 rpm.The quality indicators of the produced card sliver were determined using an USTERTESTER-5 laboratory equipment. It was established that an increase in the speed mode of the main working bodies within the studied limits on carding machines does not cause a deterioration in the combing quality.
