The treatment of cellulosic fibre materials before or after dyeing or printing with direct or reactive dyestuffs is carried out with aqueous liquors which contain quaternized polyethers which are obtained by condensation of N-2-hydroxyalkylamines of the formula ##STR1## in which R.sub.1 and R.sub.2, independently of each other, denote hydrogen or a C.sub.1 -C.sub.4 -alkyl radical and

Process for treating cellulosic fibre material

The invention relates to fibre or filament mixtures consisting of high shrinkage side-by-side bifilar (mod)acrylic fibres or filaments separately containing TiO.sub.2 and carbon black and of normal fibres or filaments of polyamide, polyester, polyalkylene, poly(mod)acrylic, wool or cotton.

Fibre and filament mixtures containing high-shrinkage bifilar

This invention relates to urethanes which contain at least one sulphonic acid group and at least two free OH-groups and to a process for the preparation thereof.

Polyalkylene oxide-containing urethane polyols with sulphonic acid groups

The instant invention relates to dihydroxy carbamates containing sulphonic acid groups, and to a process for their production. They are obtained by the addition of bisulphites to unsaturated carbamates.
