SDCE Blue Wools

SDCE LightFastness Standards 1 to 8 each pattern 15x25cm

These are a series of 8 wool fabrics dyed with specifiedblue dyes to give blue wool cloths ranging from very low light fastness to veryhigh light fastness. This forms a numerical scale of 1 to 8 where 1 has thepoorest light fastness, to 8 which has the best light fastness. This allowsfabrics to be graded, using a Grey Scale for Change in Colour, for correlationwith performance in use. This is used to predict the suitability for a givenend use; typically apparel would be a minimum of grade 4 whilst furnishingswould require a grade 6. They are used in the ISO 105 B series of tests and canbe used in conjunction with the Humidity Control fabric for machinecalibration.
