PROBLEM TO BE SOLVED: To obtain a formed underwear improving defects such as heat insulating properties, color developing properties and easy-care properties by using the acrylic staple fibers, which the conventional formed underwear composed of filaments such as nylon, or cotton and a polyurethane has and improved in pill resistance which is a disadvantage of acrylic staple fibers.;SOLUTION: (1) This formed underwear is characterized in that the constituent ratio of a nonstretchable fiber yarn to a stretchable fiber yarn is 65-99 wt.% and the ratio of the stretchable fiber yarn is 35-1 wt.% in the formed underwear composed of the nonstretchable fiber yarn containing 41-100 wt.% of the acrylic staple fibers having 0.3-3.3 dtex single fiber fineness and the stretchable fiber yarn. (2) The formed underwear is characterized in that the product of the loop strength (cN/dtex) of the single fiber of the acrylic staple fibers and the loop elongation (%) thereof is 1-20.;COPYRIGHT: (C)2002,JPO
