Definitions
- the present invention relates to a new process for the production of cellulose fibers spun from solvents with a reduced tendency to fibrillate by treating the fibers with certain reactive compounds.
- GB-A-2 043 525 describes the production of cellulose fibers by spinning a cellulose solution in a suitable solvent, e.g. an N-oxide of a tertiary amine, such as N-methylmorpholine-N-oxide, is known. In such a spinning process, the cellulose solution is extruded through a suitable nozzle and the resulting fiber precursor is washed in water and then dried. Such fibers are referred to as "solvent spun fibers".
- Such cellulose fibers spun from solvents offer many technical advantages, but tend to fibrillate. These are the splicing off of the finest fiber fibrils, which can lead to problems when processing the cellulose fibers in textile production.
- WO-A-92/07124 recommends treating the cellulose fibers with an aqueous solution or dispersion of a polymer which has a large number of cationically ionizable groups, e.g. a polyvinylimidazoline.

Nevertheless, the polyisocyanates used according to the invention have a pot life of several hours in the aqueous liquor, i.e. the present polyisocyanate dispersions are stable within the usual processing time. A dispersion is said to be stable if its components remain dispersed within one another without separating into discrete layers.

- Lower polyester diols or polyether diols can also be used as starters for the preparation of the lactone polymers.

- the polyether diols which can optionally be used in a mixture with polyester diols are in particular by polymerization of ethylene oxide, propylene oxide, butylene oxide, tetrahydrofuran, styrene oxide or epichlorohydrin with themselves, for example in the presence of BF 3 or by addition of these compounds, if appropriate in a mixture or in succession available on starting components with reactive hydrogen atoms, such as alcohols or amines, for example water, ethylene glycol, propylene glycol (1,3) or - (1,2), 4,4'-dihydroxydiphenylpropane, aniline.
