In this paper the simulation of prediction on ladies clothing image from fashion information was tried using the analysis of terms frequency appeared in newspapers presented in the previous report. The data were used on recent two seasons, namely '88 fall-winter and '89 spring-summer. The simulation means clarification of correlation between frequency of each term used in fashion trend information appeared in two seasons mentioned above and that of actual market tendency. It is concluded that more reliable trend prediction with closer correlation to actual market tendency can be acquired by following procedure: 1. As a whole the fashion trend information in newspapers has predicted the tendency for the coming season roughly. However, in order to improve the reliability, some correction are necessary on the predicted values on each term by using their past tendency. 2. In the case of several usual terms that shared major parts in the frequency ranking list, better correlation was induced by using of the average appearance frequency in past several seasons in stead of the frequency value of the trend information. 3. With regard to fluctuating terms that the frequency of appearance fluctuated often in every season and new terms interchanged with old terms season by season, the average frequency of appearance in past several seasons is not related to the trend prediction. In this case the better correlation with the actual market tendency was acquired adopting the extrapolation from the trend of recent three seasons.
The purpose of this study is to compare changes in structures of molecules of resin finished cellulosic fibers caused by thermal treatment with the thermal analytical observations., i. e., thermel degradation onset point, weight loss, end- and exothermal behavior and apparent activation energy. Cotton and viscose rayon fabrics were treated with melamine (M), urea (U) and glyoxal (G) type resins respectively followed by heating with a programming rate of 10°C/min. The structual change to be brough about by thermal treatment was presumed by changes in characteristic absorption of infrared absorption spectra, that is, ratio of characteristic absorption (at 1700-1720 cm-1for carbonyl group to be produced by heating, at 1560 cm-1for M type resin, 1540cm-1for U type resin and 1700-1720 cm-1for G type resin) to the absorption at 2900 cm-1for streching vibration between C-H bond typical for the skeletal structure were regarded as measures for the structural changes. These ratios showed typical differences between kinds of resins as well as between cotton and viscose, that is, ratios of absorptions at 1560 cm-1and 1540 cm-1decreased with rise of temperature, while absorption at 1700 cm-1enhanced by increase in carbonyl group and reduction of absorption at 2900 cm. Comparison between changes in values of 1700 cm-1/2900 cm with elevating temperature and the above mentioned thermal analytical observations showed very good agreement in all cases. Thus, these thermal analytical behaviors well reflect in appearance of carbonyl group and its increase and structural change revealed by reduction of absorption at 2900 cm-1. It has been also shown by change in ratio at 1700 cm-1that in the case of cotton fabric treated with G type resin, structure of finished cellulosic fibers is largely dominated by cotton cellulose because of chemical bonding between resin monomer and cellulose molecules, while there is no interaction between resin and cellulose molecules in the case of viscose.
