Embodiment

[0047] The thermal insulation cloth 20 constituting the example is a woven cloth made of cross-linked acrylic fibers formed of a cross-linked acrylic resin represented by Chemical Formula 1, blended yarns of acrylic fibers (by mass, cross-linked Type acrylate is 70%, acrylic fiber is 30%: 192dtex), and the surface is fluffed. As shown in Table 1, the thickness is 2.2mm, and the item payment (weight per unit area of ​​Japanese fabric) is 174g / m 2 , bulkiness is 12.6cm 3 / g.

[0048] In the woven fabric forming the underwear main body 40, in terms of mass percentage, the nylon fiber yarn of 33dtex is 61%, the polyurethane fiber yarn of 22dtex is 9%, and the cotton yarn of 80 / 1 count is 22%. The modulus is 4% viscose and 4% acrylic. In addition, the above-mentioned acrylate is a copolymer of acrylonitrile and acrylate, and is not cross-linked.

[0049] As shown in Table 1, the thickness of the woven fabric forming the panty main body 40 is 0.79 mm, the weight (weight per unit...
