Dye dispersing power and antistatic power of polyoxypropylene polyoxyethylene glycols prepared from polypropylene glycols, the molecular weight being 1200, 2000, 3000 and 4000 respectively, were investigated.
The rates of dye-absorption and migration were also observed, using the copolymers as dyeing assistants. For the dyeing of wool with 2 : 1 metal complexes dyes, the copolymers of polypropylene glycol, the molecular weight being 2000 with 400 moles of ethylene oxide, showed excellent results.
For Tetron, the copolymers of polypropylene glycols having molecular weight of 12000 with 100 moles and 200 moles ethyleneoxide showed good results.
