Assess the potential of 'yellowing' with our test kit
Our predictive phenolic yellowing test kit is designed to assess the potential for either white or pastel-coloured yarns, fabrics or garments to suffer from ‘yellowing.’ This is often a common occurrence amongst light coloured fabrics which can be caused due to both chemical and environmental factors, and fabric ageing.
The James Heal test kit is the original, developed by Courtaulds research. Designed in order to investigate complaints that particularly arise during either transit or storage. Please beware of copies and counterfeit products in the marketplace. These can, not only diminish the accuracy or consistent of results but may also cause health and safety issues.
