The present invention relates to a method for air jet texturizing or air entangling a silk filament or multifilament. Further, the present invention relates to a texturized or entangled silk filament or multifilament obtained by this method. Furthermore, the present invention relates to a yarn comprising the texturized or entangled silk filament or multifilament. In addition, the present invention relates to the use of the silk filament, multifilament, or yarn in the textile industry.

The present disclosure provides methods and compositions for directed to synthetic block copolymer proteins, expression constructs for their secretion, recombinant microorganisms for their production, and synthetic fibers (including advantageously, microfibers) comprising these proteins that recapitulate many properties of natural silk. The recombinant microorganisms can be used for the commercial production of silk-like fibers.

The present invention concerns an isolated recombinant nucleic acid molecule comprising at least one nucleic acid sequence encoding at least one mink hair keratin protein and further comprising a heterologous promoter controlling the expression of said at least one nucleic acid sequence, as well as an expression vector comprising said nucleic acid molecule, a host cell comprising said nucleic acid molecule or said expression vector and a method of production of mink hair keratin protein using said nucleic acid molecule.

Also disclosed are processes for the production of filaments, cartridges comprising filaments, bioreactors comprising filaments, food products comprising filaments, cordage comprising filaments, woven materials comprising filaments, non-woven materials comprising filaments, and sutures comprising filaments.

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.

A method of forming collagen textile filaments is disclosed. The method includes supporting a continuous filament of collagen extrudate on a surface of a moving build platform through a fibrillating bath; transferring the filaments of collagen extrudate to at least one drying module; and moving the filament of collagen extrudate through the or each drying module. In the or each drying module, the thread is moved without support from the first roller through the drying chamber to a second roller spaced apart from the first roller. The or each drying chamber is heated by at least one heater. Related devices, products and uses of collagen textile filaments are also disclosed.

Embodiments of the invention relate generally to electrospun fibers and, more particularly, to the controlled release of an active pharmaceutical ingredient (API) from electrospun fiber scaffolds (EFSs).
