Abstract

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.
