Document Type and Number:

Japanese Patent JP6360319

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide long and short composite spun yarns capable of providing a long-lasting excellent heat insulation effect irrespective of weather to a fabric as well as wearing durability and warm feeling, and a fabric including the long and short composite spun yarns.SOLUTION: The long and short composite bundle spun yarns are formed by including a synthetic fiber filament containing far infrared radiation fine particles in a core part and hygroscopic and exothermic staple fibers in a sheath part, and has a core-sheath mass ratio (core/sheath) in a range of 20/80-50/50. It is preferable that the hygroscopic and exothermic staple fiber is any of cotton, lyocell and modal.
