• the present invention relates to regenerated collagen fibers to which water resistance, heat resistance, and heat shape memory ability are imparted, and preferably relates to regenerated collagen fibers used in fiber products such as headdress products such as wigs and extensions.
• regenerated collagen fibers generally have natural texture and appearance originating from a natural material.
• the present regenerated collagen fibers are obtained by solubilizing acid-soluble collagen or by solubilizing insoluble collagen with an alkali or an enzyme to obtain a spinning stock solution, and discharging the spinning stock solution into a coagulation bath through a spinning nozzle to form fibers.
• regenerated collagen fibers generally have higher hydrophilicity and hence higher water absorption as compared to synthetic fibers, and the regenerated collagen fibers have extremely low mechanical strength when they contain a large amount of water. This leads to deterioration of suitability as a fiber product such as headdress products such that during washing, mechanical strength significantly decreases because of the higher water absorption, and during subsequent drying, rupture occurs.
• Regenerated collagen fibers also have the problem of low heat resistance, so that, for example, if a heat set using a hair iron or the like is performed at a temperature as high as that for human hair, shrinkage or crimping occurs, resulting in impairment of visual quality.
• regenerated collagen fibers may be inferior to conventional plastic synthetic fibers in terms of degree of freedom of shape set.
• Patent Literature 1 a method is known in which to human hair fibers having essentially no heat shape memory ability, a specific aldehyde derivative and phenolic compound are applied for newly imparting heat shape memory ability.
