Dyeing and finishing is a core mid-stream process in Dongsheng Carpet’s full industrial chain. Taking over white yarn from the wool spinning process, it endows yarn with accurate color, stable color fastness and customized protective properties through eco-friendly dyeing and functional finishing. It provides batch-consistent and performance-stable dyed yarn for subsequent carpet weaving and finished product finishing, serving as a key process that determines the color reproduction, weather resistance, functionality and long-term service stability of carpets.
