As a key class for synthetic fibers, disperse dyes have historically relied on carriers that may pose health and environmental concerns. Reformulated systems now feature less hazardous carriers and increased dye uptake to reduce dye in effluent. Heat-transfer and supercritical COâ‚‚ dyeing are emerging as lower-impact technologies. B2B sourcing platforms enable procurement of disperse dyes from suppliers advancing safer and more efficient dyeing practices, promoting transparency in the synthetic textile supply chain.
