  • Concentrated flowable storage stable aqueous formulations of cold dyeing fiber reactive dyestuffs
    Patent number: 4435181
    Abstract: 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.
