Part 1 : The Fabric Model Made of Elliptic Column Yarns Covered with Fine CylindersNobuo Muto, Toshihiko Arai, Koji Nihira, Tsuneyo Tsuboi, Toshihiro Gun ...1982 Volume 35 Issue 5 Pages T72-T78

JOURNAL FREE ACCESSAuthors have previously reported that the distribution curve of a specular reflection light, i.e., goniophotometric curve, on fabrics can be calculated by using the simple cross-sectional elliptic model. The experimental results agreed well with these calculated curves. It is necessary, however, to assume a model more similar to fabrics, because the surface of fabrics is much complicated.
The goniophotometric curves were obtained by a computer simulation by using a new model, in which a parallel luminous flux was assumed to be applied to the fabrics. The new model is so assumed that fine cyliners are arranged side by side on the surface of an ellipsoid. In this computer simulation, the axis of incident flux and photodetector were assumed to be perpendicular to the filaments of fabric, and the reflection light was calculated from the view point of luminous intensity.
The method of the calculation is more applicable than that of the previous paper.View full abstractDownload PDF (616K) -
Part 1 : The Studies on the Simulator to Analyze the Microclimate within ClothingTakashi Harada, Kazuyoshi Tsuchida, Sei Uchiyama1982 Volume 35 Issue 5 Pages P203-P209

JOURNAL FREE ACCESSThe microclimate within clothing, i.e., temperature and relative humidity between the human skin and clothings, is one of the most important factors for wear comfort. The microclimate within clothings isinfluenced by the transfer properties of moisture and heat through clothing materials.
Not only many factors of clothing properties, physiological and environmental conditions are related to the microclimate within clothing, but aslo these mechanism of their properties have not been clear sufficiently.
A simulator of the microclimate within clothings is developed to analyze the transfer mechanism of moisture and heat through clothing materials. This simulator is able to measure the microclimate within clothing at the same time under the artificial conditions of temperature and relative humidity, clothing state and the sweating state.View full abstractDownload PDF (3642K) -
Part 2 : Wear Sensations of Socks and Analysis of the Microclimate within Clothing on the SimulatorSei Uchiyama, Kazuyoshi Tsuchida, Takashi Harada1982 Volume 35 Issue 5 Pages P210-P218

JOURNAL FREE ACCESSAn experimental examination has been made to investigate a relation between the results on the simulator to analyze the microclimate within clothings and the wear comfort on the field tests.
The experimental results of men's socks are summarized as follows :
(1) The wear comfort of men's socks are expressed by the subjective estimations of temperature, humidity and sense of touch.
(2) The residual sweat content of socks on the field tests have a high correlation with the residual water content of the samples on the simulator. The residual water content of the samples and the humidity within clothing on the simulator are related to the comfort sensations on the field test.
(3) The comfort sensations on the field tests are explained by the residual water content on the simulator and the compressive percentage.View full abstractDownload PDF (1217K) -

JOURNAL FREE ACCESSAlthough a variety of patents have been applied of the methods of centrifugal pipe forming of cylindrical composite materials, few studies have systematically been made in the winding characteristics. This paper classifies represenative methods of fiber winding. Their characteristics and application limits are clarified through analyses and experiments.View full abstractDownload PDF (5230K) -

JOURNAL FREE ACCESSThe diffusion curves of the women's dress fashion have been analyzed by surveying fashion magazines for the last twenty years. The fashion curves have been obtained by plotting, in time series, the appearance percentage of a specific fashion category to the total fashion item. The results are :
(1) The diffusion curve of the mini-skirt fashion at growing and fading stage has coincided with the Gaussian distribution.
(2) All diffusion curves may be classified into five listed in the Table 2 of this paper.
(3) A fashion having a greater amplitude of the diffusion curve corresponds to the showy design. By contrast, a fashion having a less amplitude correponds to the plain or simple design.
(4) There are some designs which are in fashion at thesame time, e.g., flare skirts vs. polka dots, nicher pants vs. shirt collars.
(5) Different categories belonging to the same fashion are sometimes in fashion periodically, e.g., the length of skirts, coats, etc.View full abstractDownload PDF (643K)
