Reference and standard white fabrics, market relevant textiles
All standard fabrics are especially produced for wfk – Testgewebe GmbH. Only well defined yarns are used, weaving and finishing is controlled by us.
The following table lists some of our standard fabrics and indicates their typical textile technical data (please note that actual data of individual batches may deviate from the numbers listed below):
 Area weight for washed fabric: Fabrics 10 A / 11 A are defined in DIN 53919, the weight per area shall be 170 g/m² after being washed in standard wash cycles. The unwashed fabric is approx. 160 g/m². The wfk standard fabrics 20 A and 30 A were specified using the description for the cotton fabrics to have all fabrics as similar as possible. Area weights of unwashed fabrics for 20 A / 30 A are approx. 160 g/m² as well.
market relevant fabrics
Market relevant fabrics (MRF) e.g. for testing the maintenance of whiteness over multiple wash cycles. Our MRF textiles are produced with optical brightener. This allows to get information about the influence of detergents and wash programs on brightened textiles consisting of different fibres and fibre mixtures.
