Noil Measurement and Short Fibre Content Analysis
topic
Noil percentage is measured gravimetrically as the mass ratio of extracted noil to input lap mass, with USTER AFIS short fibre content analysis of both noil and combed sliver providing fibre length distribution data that confirms the effectiveness of short fibre removal and the mean fibre length of retained combed sliver for spinning process and yarn quality prediction.
Role
Provides the quality control and process optimisation data that enables systematic management of the combing quality-yield trade-off, with regular noil percentage measurement and fibre length distribution analysis confirming that comber settings are achieving the required short fibre removal targets at the minimum noil waste percentage consistent with yarn quality specifications.
