High temperature levelling agent DS-811

High temperature leveling agent, soluble in water and general organic solvent, Which has the advantages of excellent dye dispersity, initial slow dyeing and synchronous dye uptake.

Soluble in water and general organic solvents, DS-811 has excellent dye dispersity, initial slow dyeing, excellent synchronous dye uptake, low color elimination, green environmental protection, and so on. In textile, printing and dyeing industry, Used as levelling agent for polyester fiber at high temperature and at high pressure dispersion, Suitable for fast dyeing process. It can keep dyeing in acid condition and avoid the color deviation caused by the hydrolysis of sensitive dyes. Free of its solvent and its carrier, DS-811 is helpful to improve the working environment. The product is applicable to dark color of polyester at high temperature and light color dyeing with warmed-tone at high temperature
