durchgefärbten

"Durchgefärbten" is a German adjective that translates to "through-dyed" or "uniformly colored" in English. It describes a material that has been colored throughout its entire mass, rather than just having a surface coating or dye. This means that if the material is cut or scratched, the exposed interior will reveal the same color as the exterior.

This characteristic is often a desirable quality, particularly in applications where durability and aesthetic consistency are important. For example, in the production of plastics, "durchgefärbten" plastics will not show a different color if they become scratched. Similarly, in textiles, "durchgefärbten" fabrics retain their color even after wear and tear, as the dye penetrates the fibers themselves.

The process of achieving "durchgefärbten" results can vary depending on the material. For plastics, colorants are typically mixed with the raw polymer before molding or extrusion. For ceramics, pigments are incorporated into the clay body before firing. In paper production, dyes are added to the pulp. The term emphasizes the homogeneity of the color throughout the material's structure.
