摘要： A method of treating a surface of a fiber, e.g. cellulosic fiber, with a finish in which the surface finish is applied as an aqueous emulsion stabilized at a first pH value and at the latest when applied to the fiber the emulsion is caused to destabilize by a change in the first pH value. The invention also relates to cellulosic fiber and threads thereof and to tampons made from cellulosic fiber.

摘要： The invention relates to filaments and fibers of acrylonitrile polymers, which contain 10 to 30% by weight of carboxyl groups, their use and processes for their production. The filaments and fibers exhibit, in the dry state, tensile strengths of more than 10 cN/tex and knot strengths of more than 6 cN/tex and can be processed on customary machinery and are suitable for the production of shaped structures of high water retention. The polymeric raw materials required for the spinning are produced by hydrolysis of acrylonitrile polymers using aqueous dilute acids in a heterogeneous phase system.

摘要： A fiber or filament of a swellable polymer of high tensile strength is made by spinning a polymeric raw material which is produced by agitating a suspension of solid particles of an acrylonitrile polymer in dilute sulfuric acid having an acid concentration between 40 to 50 percent by weight until the polymer is hydrolyzed to an extent that it contains from 10 to 30 percent by weight of carboxyl groups such that sticking of individual particles of the polymer to one another is avoided.
