This utility model discloses a denim fabric that is resistant to pilling and comfortable to wear, belonging to the textile field. It includes interwoven weft yarns and pure cotton warp yarns. The weft yarns consist of parallel irregularly shaped nylon, plied yarns, and hollow polyester. The plied yarns are composed of linen yarns and elastic core-spun yarns. The elastic core-spun yarns include an elastic core and a cotton fiber covering layer on the surface of the elastic core. The plied yarns combine the elastic core-spun yarns and linen yarns, which helps improve the poor elasticity of linen yarns and reduces the exposed surface of the linen yarns, thus inhibiting pilling of linen fibers and reducing direct contact between linen fibers and the skin. It also retains the good moisture absorption and wicking capabilities of linen yarns. Furthermore, the use of irregularly shaped nylon and hollow polyester with strong moisture-wicking properties, which are not easily deformed, further enhances the fabric's moisture absorption and wicking properties, while also limiting linen yarn shrinkage and further reducing contact between linen yarns and the skin.
