Abstract

Ultraviolet blocking modacrylic fibers contain an anionic surfactant in an amount of 0.03 wt % or more. The ultraviolet protection factor (UPF) rating value of the ultraviolet blocking modacrylic fibers measured according to JIS L 1925: 2019 is UPF15 or more. Thus, ultraviolet blocking modacrylic fibers that are less likely to be discolored and have excellent ultraviolet blocking properties, an ultraviolet blocking fabric and a fiber product containing the ultraviolet blocking modacrylic fibers, and a method for manufacturing the ultraviolet blocking modacrylic fibers are provided.
