Pigmentlastingsgraden

Pigmentlastingsgraden, a term originating from German, translates to "degree of pigment retention" or "color fastness" in English. It refers to the ability of a colored material, such as fabric, paint, or ink, to resist fading or discoloration when exposed to various environmental factors or treatments. This property is crucial in determining the durability and longevity of colored products.

Factors influencing pigmentlastingsgraden include light fastness (resistance to fading from sunlight), wash fastness (resistance to color loss during washing), rub fastness (resistance to color transfer when rubbed), and resistance to chemicals like perspiration or dry cleaning solvents. Different applications demand varying levels of pigment retention. For instance, outdoor textiles like awnings require high light fastness, while clothing needs good wash fastness.

Testing methods are employed to quantify pigmentlastingsgraden. These typically involve exposing the colored material to standardized conditions simulating real-world exposure and then evaluating the extent of color change using specialized scales or instruments. A higher rating indicates better color retention and a more robust color performance. Understanding and improving pigmentlastingsgraden is a significant aspect of material science and product development.
