The Sliver Quality and the Rate of Fiber Transfer of the High Production Card

고속소면기의 섬유의 이행솔과 Sliver 품질

In order to investigate the performance of high production card, some experiments were carried out on the fiber transfer rate, neps in the web and irregularity of card sliver with the various factor such as; density of metallic card clothing on the doffer, speed of cylinder, setting of flat and doffer, speed of doffer, weight of sliver, and micronaire value of cotton. As the results, the following conclusions were obtained; The density of metallic card clothing on the doffer and its speed were the most prominent factors on the fiber transfer rate. Large fiber transfer rate produced the cloudy web and it was thought that large fiber transfer rate brought less back doubling effect on the cylinder. When the speeds of cylinder were not increased. Within the range of present experiment, fiber transfer rate was not changed in accordance with the change of micronaire value.
