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.

Abstract: A heat-generating fabric contains an modacrylic fiber A and an animal hair fiber. The modacrylic fiber A contains an infrared absorber inside of the fiber, in an amount of 1 to 30% by weight with respect to the total weight of the modacrylic fiber, and the fabric has a heat-shielding rate of less than 40% as measured according to JIS L 1951:2019. The heat-generating fabric contains a first yarn and a second yarn whose fiber composition is different from that of the first yarn. The first yarn may contain the modacrylic fiber A, and the second yarn may contain the animal hair fiber. Accordingly, it is possible to provide a fabric with good heat-generating performance and durability, and a textile product containing the fabric.

Abstract: A flame-retardant fiber composite includes an acrylic fiber A containing an acrylic copolymer and an aramid fiber. The acrylic fiber A is substantially free of an antimony compound, and the flame-retardant fiber composite forms a surface-foamed char layer when burned. A flame-retardant work clothing includes the flame-retardant acrylic fiber. A highly flame-retardant fiber composite and highly flame-retardant work clothing include an acrylic fiber, and are capable of exhibiting high flame retardancy while suppressing environmental impacts caused by a flame retardant.

Abstract: An arc resistant acrylic fiber includes an acrylic polymer. The arc resistant acrylic fiber also includes an infrared absorber in an amount of 1 wt % to 30 wt % with respect to a total weight of the acrylic polymer.
