Abstract
Water-insensitive starch fibers having an amylopectin content of about 55 to 100% by weight are prepared by extruding a colloidal starch dispersion in thread-like form into a moving coagulating bath. Water-insoluble additives may be incorporated into the starch dispersion so as to produce a fiber containing the additive in encapsulated form.
