Abstract: Disclosed is a method of forming a collagenous textile filament. The method comprises supporting a continuous thread of collagenous extrudate upon a moving build platform surface through the liquid of a fibrillation bath; transferring the thread of collagenous extrudate to at least one drying module; and moving the thread of collagenous extrudate through the or each drying module. In the or each drying module, the thread moves unsupported through a drying cavity from a first roller to a second roller spaced apart from the first roller. The or each drying cavity is warmed by at least one heater. Also disclosed are related apparatus, products and uses of the collagenous textile filament.

Abstract: Coated Fibrous Substrates The present invention provides a method of improving the adhesion of coatings to fibrous base materials. The method comprises treating a fibrous base material with one or more salt(s) of receptor species to provide a pre-coated fibrous base material comprising specific inorganic receptor sites within the fibrous base material. The one or more salt(s) of receptor species is selected from the groups comprising: (a) aluminium salts; (b) titanium salts; (c) zirconium salts; (d) iron salts; (e) soluble alkali silicates; or a combination thereof. The method further comprises coating the treated fibrous base material with a coating formulation comprising one or more compound(s) containing epoxy and alkoxysilane groups. The coating formulation acts as an adhesion promoter and cross-linker.
