Comber Settings for Different Quality Levels
topic
Comber quality-yield trade-off is controlled by detaching roller setting, nip gauge, and circular comb clothing density, with each millimetre reduction in detaching roller to nip distance increasing noil by 2 to 3 percent while improving combed sliver length uniformity; fine yarn production requires 18 to 25 percent noil for maximum quality while coarser combed yarns accept 12 to 16 percent noil for economic yield.
Role
Enables mill management to optimise the economic balance between yarn quality improvement and raw material cost by systematically relating comber setting parameters to noil percentage and combed sliver quality outcomes, determining the minimum noil extraction needed to achieve required yarn quality targets for each product and avoiding unnecessary noil waste that increases raw material cost.
