Document Type and Number:
Japanese Patent JP3130617
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject fiber not causing the generation of waves even on the adhesion of water, having excellent water resistance and suitable for wigs, etc., by adjusting the swelling rate of a soluble collagen within a prescribed range, and subsequently treating the treated collagen with a metal salt aqueous solution.
CONSTITUTION: Soluble collagen is dried and subsequently treated with a water- soluble organic crosslinking agent such as formaldehyde (in a concentration of preferably 0.3-5wt.%) to give a swelling rate of 100-300% followed by treating the product with a metal salt aqueous solution such as chromium sulfate (in a concentration of preferably 0.2-5wt.% converted into the metal oxide) to obtain the objective fiber.
