Resumo(s): | The wool and cotton spinning processes are quite different, regarding the opening, cleaning and blending operations. However, yarn formation with different parameters due to fiber characteristics (length and origin) could take place in the same machine. Factors involved are the drafting and twisting parameters. In this work, a preliminary study regarding the use of the ring spinning process to produce wool and cotton yarn is carried out concerning the drafting system, as this is one of the major differences between the process for the two materials. During the drafting operation, fibers must be moved relatively to each others as uniformly as possible, by overcoming friction between them. As they show different average lengths, it is necessary to provide means for automatic adjustment of the roller distance according to the type and length of fiber being processes. |
