Discolouration caused by sunlight.

The extent of discolouration is expressed in terms of a number between 1 and 8 on the blue scale, where 1 is the lowest discolouration and 8 is the highest discolouration.
A lightfastness value of 6 means in practice that the fabric will show slight discolouration after approximately two years (provided that it is not exposed to direct sunlight).
De Ploeg has a lightfastness value of 5 as standard and strive to achieve a lightfastness value of 6.


Weight in grams per linear metre.


Pilling is where protruding fibres get twisted into small balls on the surface.


Resistance to abrasion

naad- schuifweerstand

De Ploeg tests upholstery fabric for its sensitivity to the stitching coming open.

In general, it can be said that a fabric where the yard threads can slip a maximum of 6 mm from each other does not give a problem. If the seam slippage is less, then it is recommended to pay extra attention when upholstering by using double stitches and serging the edges.
