Slub Yarn Attachment Systems for Ring Frames
topic
Slub yarn attachments on ring frames use servo-controlled variable-speed back or middle roller drives programmed to periodically reduce drafting speed creating localised thick places of defined length, spacing, and thickness ratio in the spun yarn, with electronic programming enabling infinite variation of slub pattern parameters to create custom slub sequences matched to specific fabric design requirements.
Role
Produces the irregular thick-thin slub yarn structures used in slub cotton fabrics, linen-look shirting, and denim where deliberate yarn count variations create the characteristic surface texture that differentiates these fabric aesthetics from regular yarn constructions, with programmable slub pattern generation enabling rapid design development for seasonal fashion yarn collections.
