PROCEDIMENTO DI FILATURA AD ANELLI E FILATOIO AD ANELLI

摘要

The ring spinning method drafts a silver in a multi-stage drafting system where the silver acquires a total draft in a range of from 60 to 150-fold. Following outlet from the last nip of the drafting system, the drafted silver is conveyed without drafting over a guide path in which the fiber band is condensed to form a compact fiber strand of not more than 2.5 millimeters width and preferably less than 15 millimeter in width. At the end of the guide path, the fiber strand passes through a twist inhibiting nip between two rollers and is then passed by twist distribution to a ring spinning device. The yarn produced possesses a high quality with respect to hairiness and neps.
