Barré: Visual Assessment and Grading
Developed in 1992 by AATCC Committee RR97
1. Purpose and Scope
1.1 Barré is the optical result of physical or dye differences in the yarns, geometric differences in the fabric structure, or any combination of these differences. This test method provides a standard procedure for evaluating barré intensity and for describing pattern characteristics based on visual comparison to a Uniformity Reference Scale and description of the barré pattern using a standard terminology. It can be used with knitted fabrics, woven fabrics and garments. The standard terminology is particularly useful in oral and written communications.
