All the yarn dyes used by Ian Mankin have a lightfastness of 4 or over on a scale of 1-5. The dyes used in fabrics that are marked as washable at 30°C should not fade as long as optical brighteners are not contained in the detergents.
Due to the nature of undyed and unbleached fabrics such as natural linens, cotton and viscose, you may notice colour fade if these are exposed to strong light over a long period. To keep their natural beauty, we would recommend that these fabrics are kept away from strong sources of light or that a protective film is used on windows if this is unavoidable. Our undyed and unbleached yarns achieve a colourfastness of 2 on a scale of 0 – 5.
As with all fabrics, it’s important to follow the care instructions as shown on our product pages, please lookout for the following symbols:
Please note that undyed natural fibres such as linen, cotton and viscose may lighten in colour when washed and caution should be taken when spot cleaning natural fibres as colour may leach to form watermarks.
If you are using this fabric for a product you intend to wash such as removable covers and soft furnishings, please take into account the possible 5-10% shrinkage when measuring or briefing a maker.
All of our fabrics are tested for rub fastness on an industry standard called the Martindale Test; this gauges how many times a fabric can be rubbed in a circular motion before the abrasion starts to break threads. Please see the individual product specifications for their usage and suitability.
