SDCE Phenolic Yellowing Kit

SDCE Phenolic Yellowing Products

For BS EN ISO 105 X18:2007 Textiles - Assessment of the potential to phenolic yellowing of materials.

Based on a method developed around 1985 by Courtauld’s Research, this test

can be used to screen fabrics for their susceptibility to exhibit Phenolic, or elusive, yellowing – where garments or fabrics exhibit yellowing making them unfit for sale without re-processing.

Through extensive sampling and testing procedures, SDCE products are not only are guaranteed to conform to the standard, they also have excellent continuity of performance from batch to batch over many years. Testing not only includes practical and independent performance testing but also quantitative analysis of the concentration of active ingredient on the papers.

Due to the limited shelf-life of the papers, (3 months once the heat-sealed barrier foil bags have been opened), SDCE pack all their papers in small pack sizes to reduce waste or the temptation to use up out-of-date papers. Also, SDCE have developed a woven tape for the control fabric, this relatively heavy construction makes assessment and grading of the yellowing easier for the technician.
