Abstract
The present invention relates to a water-resistant regenerated collagen fiber containing 12 wt % or more of zirconium salt in terms of zirconium oxide and 2 wt % or more of phosphorus compound in terms of phosphorus. The present invention also relates to a method for producing a water-resistant regenerated collagen fiber, and the method includes treating a regenerated collagen fiber with a zirconium salt to incorporate the zirconium salt into the regenerated collagen fiber, and then treating the regenerated collagen fiber with a phosphorus compound to incorporate the phosphorus compound into the regenerated collagen fiber, thereby obtaining a water-resistant regenerated collagen fiber containing 12 wt % or more of zirconium salt in terms of zirconium oxide and 2 wt % or more of phosphorus compound in terms of phosphorus. The present invention also relates to a fiber bundle for hair including 30 to 100 wt % of the water-resistant regenerated collagen fiber and 0 to 70 wt % of polyester-based fiber.
