摘要： The present disclosure is concerned with aqueous dispersions of anionic acid dyes, especially the monosulphonated level dyeing acid dyes, which have low room temperature, low shear viscosities and good storage stability. This low viscosity enables them to be readily poured, pumped and otherwise handled. These dispersions comprise dyestuff solids with a controlled particle size distribution having a median value between about 1 and 10 microns; an anionic dispersant; and an electrolyte. In a preferred embodiment the pH is adjusted to give an optimum viscosity value. Another preferred feature is the adjustment of the rheology with a thickening agent such as xanthan gum. These dispersions find particular utility in the continuous dyeing of carpet, especially in Kuesters or foam dyeing equipment.

摘要： The present disclosure is concerned with storage stable concentrated fluid aqueous dispersions of water soluble cold dyeing fiber reactive dyes. These dispersions contain anionic or polyvinyl dispersants to provide resistance against settling or agglomeration and water soluble electrolytes to provide resistance against hydrolysis of the fiber reactive groups. The dispersions have an average particle size of less than 100 microns and in a preferred embodiment sufficient buffering agent to stabilize the pH at between about 5 and 8.
