Abstract
Fancy yarns which are also termed as novelty yarns, specialty yarns, effect yarns and fashion orientedyarns. Effect yarns are yarns which are given pre-programmed characters at spinning stageelectronically controlled, and consequently 100% reproducible. It is generated during the spinning process by controlling yarn diameter and length structure of the yarn, by effect devices. Our ultimate aim is to develop electronic programme(EP) for fancy yarns such as slub, Multicount and Multitwist of cotton and polyester-viscose blend using amsler device attached to the LG 5/1 Ring frame machine and provide information about properties, which is measurable and quantifiable, which forms the basis of this paper. Fancy yarns produced showed significant variation for properties like tenacity, breaking elongation, breaking time, U%, relative resistance value and twist per inch, but no significant effect was seen for properties such as hairiness and friction. Multicount yarn is suitable for weaving onhigh-speed looms with eye-catching look.
Keywords: Classification, Effect device, Slub, Multicount and Multiwist.
