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 synthetic fiber of acrylic series having an excellent animal-hair feeling is provided. The surface of the fiber having unevenness, in which the center-line mean roughness of the outer periphery of the cross-section of the fiber lies within a range of 0.01 to 0.13 .mu.m, is adhered thereon with an organopolysiloxane, wherein an effect by a treatment with silicone may be obtained to a greatest extent to provide the fiber having an extremely excellent animal-hair feeling. The kinds and amounts of additives to be added to a spinning solution may be so controlled that the roughness of unevenness on the surface of the fiber lies within the above range, thereby the appearance of the fiber with or without gloss may be selected. When the roughness of the surface unevenness lies within the above range and the cross-section of the fiber is a circle, or a flat or oval section having an aspect radio of 10 or less, a fiber having an extremely excellent animal-hair feeling may be obtained.
