This study shows the enhancement of thermal properties and the change of hand values due to the hollowness by comparing properties of fabrics made form hollow fibers are better compared with fabrics made from regular fibers, except for the frictional properties. the thermal properties measured by KES-F7(Thermo Labo II) system shows that the values of the initial maximum value($q_{max}$) and the thermal conductivity(λ) are higher in the fabricsmade from hollow fibers.
