Latest Patents

Dao Xu holds a patent for an AZO dye specifically designed for waterless dyeing of natural fibers in supercritical CO2 fluid. The invention discloses a special-purpose reactive disperse dye that features a longer alkane-chain bridging group between a chromophoric parent structure and an active group of the dye. This innovative approach effectively promotes the donating-withdrawing effect on the electron cloud in the conjugated system, enhancing the hyperchromic effect. It also reduces the influence of the active group itself and its reaction on the dye coloring system. The improvements lead to better color stability against acid and alkali, as well as enhanced compatibility of the dye with supercritical fluid, ultimately improving dyeing performance for natural fibers.
