Influence of Delayed Timing on Knitted Fabric Characteristics

Abstract

Delayed timing is a complex adjustment of large-diameter circular knitting machine (LCKM). It corresponds to the delay between cylinder and dial needles knock-over. It is generally not well-known by machines users and its impact on fabric properties has not been enough studied in literature. Knitters generally use experience during delayed timing adjustment in order reach needed fabric characteristics. The aim of this paper was to investigate the relation between delayed timing intensity and yarn tension, yarn consumption, fabric weight as well as loop length and shape. The obtained results showed that delayed timing has an incidence on fabric weight and loop shape especially at fabric back side. The origin of this influence has been discussed and related to needles feeding mechanisms.
