ABSTRACT:
An apparatus for forming a collagen fiber having microparticulates coated on the fiber surface includes a device for forming a continuous stream of liquid collagen, a coagulation bath wherein the continuous liquid collagen stream can be formed into a continuous collagen gel fiber, a dehydrating bath, wherein the continuous collagen gel fiber can be partially dehydrated and further polymerized, and a device for coating particulates on the surface of the fiber. The method includes directing a liquid collagen solution into a coagulating bath to form a continuous collagen gel fiber, transferring the fiber to a dehydrating bath so that the fiber is partially dehydrated and further polymerized, removing the dehydrated fiber from the dehydrating bath, coating the surface of the fiber with microparticulates, and stretching and drying the coated fiber.
