The effect of eight different spinning front and back line cots (Synthetic rubber cot) varying only in shore A hardness (65°,83°) on 100% cotton 30’s ring spun yarn has been investigated. The change in cotton yarn properties like mass uniformity, unevenness percent, Imperfection levels (in all class) with progressive change in shore A hardness has also been reported. The count and process parameter’s from opening and cleaning machines that covers blow room and carding then breaker and finisher drawing, speed frame and up to ring spinning kept identical. As one progress from lesser shore hardness (65°) to higher shore hardness (83°) the yarn unevenness percent and imperfection levels gradually increases.
