SDCE Blue Wools

SDCE Light Fastness Standards 1 to 8 each pattern 15x25cm

These are a series of 8 wool fabrics dyed with specified blue dyes to give blue wool cloths ranging from very low light fastness to very high light fastness. This forms a numerical scale of 1 to 8 where 1 has the poorest light fastness, to 8 which has the best light fastness. This allows fabrics to be graded, using a Grey Scale for Change in Colour, for correlation with performance in use. This is used to predict the suitability for a given end use; typically apparel would be a minimum of grade 4 whilst furnishings would require a grade 6. They are used in the ISO 105 B series of tests and can be used in conjunction with the Humidity Control fabric for machine calibration.

SDCE Wool Abradent-5 meter Pack

Testing and quality control are carried out at the yarn stage, after weaving of the greige fabric and the final finished abradant cloth. This ensures excellent correlation and conformity, not only within the production batch, but also between different production batches. Available in 5metre packs or in pre-cut 175mm discs.
