Abstract
A cylindrical body is produced which is composed of a fiber structure with a basis weight of 1-50 g/m2 and having a diameter of 0.5-50 mm and a bellows-shaped section, wherein the crest-to-crest spacing of the bellows-shaped section is no greater than 2 mm and the crest-to-valley depth of the bellows-shaped section is 0.01-1 mm; collagen is added to the cylindrical body to produce a composite including the cylindrical body and collagen.
Claims3
A method for the production of a cylindrical body composed of a fiber structure with a basis weight of 1-50 g/m2, wherein the cylindrical body has a bellows-shaped section, wherein the spacing of the bellows-shaped section is no greater than 2 mm and the depth of the bellows-shaped section ranges from 0.01-0.1 mm, the method comprising:
- 1) producing a solution of an aliphatic polyester in a volatile solvent, 2) spinning said solution by an electrostatic spinning method to form a fibrous structure on a mandrel having a surface roughness ranging from 0.2-S to 400-S, and 3) forming the bellows-shaped section by first securing one end of the formed fibrous structure against the mandrel and then pulling said mandrel out of the fibrous structure in the direction toward the secured end.
