Title:
GELATIN FIBER AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/054553
Kind Code:
A1
Abstract:
It is intended to provide a gelatin fiber which has a lower toxicity and yet a higher strength than the existing gelatin fibers. A process for producing a gelatin fiber characterized by comprising heating an aqueous gelatin solution to convert it into a sol and then spinning the heated aqueous gelatin solution in the atmosphere. It is further characterized by comprising spinning an aqueous gelatin solution containing dimethyl sulfoxide in a solidifying solution. It is further characterized by comprising spinning an aqueous gelatin solution containing a hydrophilic solvent in the atmosphere or a solidifying solution. It is furthermore characterized by comprising spinning an aqueous gelatin solution containing a polyvalent glycidyl compound in the atmosphere or a solidifying solution.
