    The regional thermal resistance of sixty-four kinds of women's underwears, i.e., panties, girdles, brassieres, camisoles, petticoats, shirts and stockings, has been determined by using a life-sized thermal manikin. The profile of the regional thermal resistance has been discussed of twelve combinations of panty, girdle, brassiere, stocking etc., which are put on the thermal manikin under the one-piece dress.
    The experimental results have shown that the do value of each garment well fits to the following formuli.
    Y= 0.00103W-0.0253 (r2=0.98)
    Y= 0.828X+0.0125 (r2=0.98)
    where, Y, W and X are total clo value, total weight of garment and sum of do value of each garment respectively.

    The dimensional change of fabrics during the wear is one of typical fatigue phenomena, which is called as “Bagging”. In order to give basic data for fatigue prediction, the dimensional change of double knitted fabrics is studied and discussed in relation to the change of other mechanical properties which was studied in the previous paper. The distortion and the recovering process after the cyclic shearing deformation under a constant extension are measured and analyzed by the same exponential approximate as in the previous paper, where αl, βl and T0 are the dimensional residual value, recover value, and the recovering time constant respectively.
    Following results are given by these parameters:
    1) The residual value αl shows an increase with the increasing of deformation repeating times n, and recovered ratio (βlll) represents well the advance of fatigue phenomena.
    2) The difference of dimensional recovering properties can be observed between fabric of Pontide-Roma structure and those of Interlock structure.
    3) Worsted double knitted fabrics show less amount of αl than that of textured fabrics.
    4) Residual extension amount can be related to the hysteresis of shearing and tensile properties of undeformed fabrics.
