FIBER STRUCTURE

摘要

Provided is a fabric having a ground structure in which a hygroscopic polymer has been fixed, which fabric not only generates heat in moisture-absorbing conditions but also drops in temperature in moisture-releasing conditions, thereby allowing a person to feel more comfortable. A fiber structure obtained when a hygroscopic polymer is fixed to fibers of a fabric, wherein a front layer on a front surface side and a back layer on a back surface side, the boundary for which is the center line of the fiber structure cross-section, have different fiber densities.
