    This study aims to find out the relationship between the wearing comfort of underwears and the physical properties of the materials. As the physical properties of the materials, measurements were carried out on the mechanical, surface, heat transport and water transport properties. The wearing comfort of underwears was evaluated by ten women and four men. The results are as followes:
    1) The wearing comfort of the two-layered knitted fabrics was shown, compared with that of cotton knitted fabrics.
    2) The relationship was found between the physical properties and the wearing comfort. Therefore, it was understood that the wearing comfort of underwears may be predicted from the physical properties of the materials by considering the wearing condition.
    3) It was found out the terms of the wearing comfort which contribute to the total comfort of underwears by the use of principal component analysis and regression analysis.

    Using thermal mannequins, unlined long women's kimono were made using different Japanese clothing fabrics, then the thermal resistance of the clothing, were studied. Results clarified the following points.
    1) Thermal resistance of the clothing was within the 0.45-0.57 clo when there was no wind, while it dropped 3.0-41.6 % when there was a wind. The thermal resistance of the clothing was found to be closely related to air permeability.
    2) The thermal resistance of the clothing showed a high correlation with experiments involving cylinder models (with a 4 mm air layer) and showed the validity of the cylinder expveriments.
    3) The structural features of Japanese clothing show high heat retention from the shoulders to the upper arms and from the hips across the thighs, with low heat retention in the chest, back, forearms and lower legs and medium heat retention in the hips and abdomen.

    Up to the present, the evaluation of the detergency has been mainly carried out concerning the soils on the white cloth.
    However, concerning the soils on the dyed cloth, at present, the quantitative information has not become clear. This is why the evaluation by Harris' detergency which has been used generally are not appropriate.
    Therefore, in order to express the detergency based on the visual evaluation, regardless of the white or dyed cloth, an attemption has been made to prepare the private gray scale for detergency corresponding to the gray scale for color fastness determination.
    When this private gray scale was prepared based on ND value with α= 1.5, ω= 1.54, this scale coincided fairly with visual evaluation. Then, when the achromatic specimens were evaluated by using this gray scale, the visual evaluation resulted with ease and the value corresponding to the gray scale grade were obtained.
    But, in the visual evaluation, there are unavoidable difference among individuals. Therefor, an instrumental measurement are required to get the accurate and stable evaluation.
    The trial preparation of the private gray scale for detergency in this experiment are considered to be an intermediate step to more accurate evaluation of detergency.

    Formability which indicates the ability of plane fabrics to be fitted on curved surface, is required for constructive tailored clothes.
    Formability of different structures of women's fabrics, namely, woven, knitted and non-woven fabrics and its relations with the mechanical properties of the fabrics were studied. The results are summarized as follows:
    1) Formability of woven and knitted fabricis is mostly dependent on shearing property and tensile property, respectively.
    2) From the analysis of the relations between formability and mechanical properties of the fabrics, it was found that formability was described as a function of (G+HG5), (EMT/LT) and (B+HB) .
