VERFAHREN ZUR HERSTELLUNG VON FASERN MIT HOHEM KOLLOIDALEN TEILCHENANTEIL UND DARAUS HERGESTELLTE ZUSAMMENGESETZTE FASERN

摘要

The invention relates to a method for the production of composite fibers with an increased content of colloidal particles, made from a pre-fiber, comprising a polymeric binder and colloidal particles, during which the chemical structure of the polymeric binder is degraded at a temperature of the order of ambient temperature such as to at least partially eliminate the above. The invention further relates to a fiber comprising a polymeric binder and colloidal particles, combining an excellent mechanical strength and a content of colloidal particles greater than 70% by mass.
