Abstract

A multilayer structured spun yarn (20) includes core component fibers (21) and sheath component fibers (24). The core component fibers (21) are a multifilament yarn. The sheath component fibers (24) include inner layer fibers (22) and outer layer fibers (23). The inner layer fibers (22) are untwisted and entirely bundled by the outer layer fibers (23) wound therearound in one direction. The sheath component fibers (24) are a blend of short fibers A with an average fiber length of 10 to 25 mm and short fibers B with an average fiber length of longer than 25 mm and 51 mm or shorter. The multifilament yarn of the core component fibers serves as a connecting yarn. The blending proportion of the short fibers A is preferably 0.1 to 20 mass % with respect to 100 mass % of the multilayer structured spun yarn (20). Accordingly, the present invention provides a multilayer structured spun yarn whose yarn properties and properties when the yarn is formed into a fabric are made comparable to those of conventional products by optimizing the yarn structure even when fibers with a short fiber length are contained, a method for producing the same, a fabric, and clothing.
