Title:
PRODUCTION METHOD OF COLLAGEN FIBER
Document Type and Number:
Japanese Patent JP2017061757
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of a collagen fiber, with which a collagen fiber having sufficient mechanical strength can be produced.SOLUTION: In a production method, fibrous collagen is formed by discharging a collagen solution into a coagulation bath through an air gap in a fibrous form, and a collagen fiber is produced by removing the solvent of the solution, while the discharged collagen solution is made to be stretched and to flow just before spinning by applying tension to the formed fibrous collagen. The discharged collagen solution is preferably made to be stretched and to flow just before spinning by applying tension to the fibrous collagen going out of the coagulation liquid with a tension roller.SELECTED DRAWING: Figure 1
