3 Principle
A specimen of the textile in contact with either two single-fibre adjacent fabrics or a multifibre adjacent fabric is immersed in sodium chloride solution, drained and placed between two plates under a specified pressure in a test device. The specimen and the adjacent fabric(s) are dried separately. The change in colour of the specimen and the staining of the adjacent fabric(s) are assessed by comparison with the grey scales or instrumentally.
