Massavärjäyksellä
Massavärjäyksellä, also known as mass coloration or dope dyeing, is a process of coloring polymers during their manufacturing. Instead of applying color to the surface of a finished product, pigments or dyes are incorporated directly into the molten polymer before it is extruded or molded. This results in a homogenous distribution of color throughout the material, offering several advantages over traditional surface dyeing methods.
The process typically involves introducing concentrated pigment masterbatches or liquid colorants into the polymer melt within
Massavärjäyksellä is widely used in the textile industry for coloring synthetic fibers like polyester, nylon, and
