Abstract
This article reports on a new type of spinning equipment which, using air flow, differs radically in the method of twisting from the ring spinning frame and which needs no ring, traveller or pot.
By this continuous spinning equipment, yarns, after spun with rovings can be wound directly into the cheese.
The equipment is capable of a spindle speed of more than 20, 000r.p.m. The yarn spun by this equipment-“.ir-spun yarn”, as we call it-has some defects, particularly in strength and elongation, when compared with ring-spun yarn.
