In textile production, one of the most common and perplexingquality issues is "barré." The factors that can cause orcontribute to barré are varied and diverse. For this reason, when a barréproblem is detected, the skills of a sleuth may be required to expose theproblem and eliminate its cause. Once a cause is identified, steps can be takento minimize or eliminate the barré, and better quality fabrics can beproduced. This discussion will center on knitted fabrics.
Identification of Barré
The first step in a barré investigation is to observeand define the problem. Barré can be the result of physical causes thatcan usually be detected, or it can be caused by optical or dyeabilitydifferences that may be nearly impossible to isolate in the fabric. Barréanalysis methods that help to discriminate between physical barré andbarré caused by other reasons include Flat Table Examinations, LightSource Observation, and the Atlas Streak Analyzer.
