PROBLEM TO BE SOLVED: To provide a composite spun yarn capable of making woven/knitted fabrics having stretchability and wearing comfortableness and having such properties as crisp feeling and feeling of coolness as well. SOLUTION: The composite spun yarn is such that a core layer of a polyurethane elastic fiber is covered with a sheath layer including a natural bamboo fiber, wherein the blend percentage of the natural bamboo fiber is 40-97 mass%. A method for producing the composite spun yarn is also provided, involving, in general, using a means such as doubling twisting, single covering or double covering. Alternatively, the composite spun yarn can be produced using a fine spinning frame. COPYRIGHT: (C)2008,JPO&INPIT
