Warmth retaining fiber structure

摘要

The present invention relates to a heat-retaining fiber structure comprising a cloth layer having a moisture/heat release control capability laminated with a cloth layer having water molecule adsorption/heat release capability, wherein said cloth layer having the moisture/heat release control capability has a moisture permeability of 3000-12000 g/m<2>.24 hr and said cloth layer having water molecule adsorption/heat release capability has an exothermic energy index of 5 or larger and a contact thermal sensation factor (qmax) of 0.1 W/cm<2 >or less. This constitution makes it possible to provide clothing having high heat-retaining performance achieved by water molecule adsorption capability.
