Structural Performance of DRF And Conventional Yarns

[Full Text]



Lokesh Shukla, Dr. Anita Nishkam



KEY WORDS: DRF Yarn, Configuration of Wool Fiber, Straight Hooked (Trailing), Hooked (Leading), Hooked (Both), Looped and Entangled, Mean Fiber Extent and Spinning-in-Coefficient (%).



Abstract:- Constituent Wool Fibers Structure in DRF and Conventional yarns were elicited in Co-relation to Processing Parameters Wool Fiber Length, Twist Multiplier and Strand Spacing by using Box and Behnken\'s Design. The Straight fiber % increases as strand spacing increases at 65 and 70 mm fiber length and decreases at 75 mm fiber length. In all strands spacing, Straight fiber % increases up to 70 mm fiber length than decreases in further increase in fiber length, and Spinning-in-Coefficient % is increases as fiber length increases. In all 3 levels of fiber length, Spinning-in-Coefficient % increases up to 14 mm strand spacing than decreases in further increase. The straight Fiber %, Mean Fiber Extent and Spinning-in-Coefficient of Wool Fiber at optimum levels of variables DRF yarns are improved in comparison to Conventional yarns. The role of TM is not visible. In DRF yarns, straight fiber % was 71 to 61, mean fibers extent was 44.10 to 53.90, spinning in coefficient (%) was 64.75 to 74.90, trailing hooks was 9 to 15, leading hooks was 0 to 10, both leading and trialing hooked was 0 to 5, looped was 1 to 4 and entangled was 0 to 4 respectively.
