Apparatus to uniformly control wrapping a filament around the surface of a spun core yarn during ring spinning |
摘要 |
An apparatus to uniformly wrap filament around the surface of a spun core yarn is disclosed. Means for fabricating a core yarn is provided. At the critical point of yarn fabrication, the spun core is simultaneously twisted or rotated on its longitudinal axis by means of ring spinning and contacted with a filament introduced by means of over-feed rollers. Helical wrapping of the filament around the surface of the staple core yarn takes place as the filament cohesively contacts the twisting core yarn to form a composite filament wound yarn.
