ジャーナル フリー布で被覆された円筒の空力特性を明らかにするため,実験を行った。被覆の外側表面(布表面)と内側表面(剛な表面)における圧力分布,及び外部領域における定常・非定常速度分布を測定した。測定した外側表面の圧力分布は,布が異なってもほとんど一致していた。しかし,これらは負圧のピークが見られない等の点で被覆の無い円筒の場合とは違っており,その原因は被覆円筒面上の剥離点が,被覆の無いときより上流にあるためと考えられる。内側表面の圧力分布は,布の透過率が小さいときは被覆の影響でなだらかになるが,透過率が大きい布の場合は外側表面の分布とほとんど変わらなかった。速度分布の測定からは,被覆による剥離点の上流〓への移動が確認された。布の透過率が小さい場合の速度分布は,剥離点以外は被覆の無い場合とほとんど同じであるのに対し,透過率が大きい場合は表面の境界が厚くなり,その乱れも大きいことがわかった。抄録全体を表示PDF形式でダウンロード (446K) -

ジャーナル フリーAttention was paid to the clingy properties of wet fabrics, which were closely related to discomfortable contact feeling. The contact resistances were measured between a metal cylinder and the hanged fabrics during moisture sorption and desorption processes by means of the changes in cylinder temperture or ambient temperature and humidity. The clingy force by water was discucssed, and the following results were obtained under this experimental condition:
(1) The contact resistance decreased during moisture sorption process and increased during moisture desorption process. A stickslip phenomenon was observeed, too.
(2) The change in the contact resistance reached the maximum value of 1.5g per the apparent contact area of 5.61cm2.
(3) It was assumed that the apparent clingy force by capillary water reached the value of the order of 10-2g/cm2.
(3) The change in the contact resistance was large for hygroscopic and wettable fabrics.抄録全体を表示PDF形式でダウンロード (626K) -

ジャーナル フリーTotal resistance R of fabrics to water vapor transmission was divided into apparent inner-resistance R1a and outer-resistance R2a from linear relation between R and number of layers for multilayered fabrics. The change in R through the adhesion of a nonwoven interlining to each woven fabric was studied in connection with R1a and R2a. This study also dealt with resistances of woven fabrics having relatively fuzzy uncertain surface.
Practical outer-resistance tended to decrease to a larger extent through the adhesion in the case of woven fabrics having rougher structure. The thickness of still air layer above the woven fabrics may be different from that above the same woven fabric which composed laminated one. This suggests that the thickness of still air layer above the fabrics may depend on the inner structure of the fabrics.抄録全体を表示PDF形式でダウンロード (411K) -

ジャーナル フリーProgress of computer aided engineering (CAE) for apparel industry is slow as compared with other fields, for instance, electric, machinery and chemical industries. The CAE for apparel has been partially developed in computer grading, computer marking, computer cutting systems and so on. The most of production process for apparel industry is still dependent on manual works. This is due to difficulty of material handling and body model for the computer system of apparel production.
Therefore, it is important to investigate the human body form for apparel engineering. In this paper, various problems regarding human body forms were studied and new methods for data reduction, representation and standardization of the human body form were explained. Furthermore, the cluster analysis of the human body form was proposed by means of power spectrum.
The method of low-pass filther was effective in data reduction. The standardization of the human body form using linear transformation of Fourier coefficient agreed approximately with the sensation of our visual feeling for forms. The cluster analysis was useful in grouping the human body form.抄録全体を表示PDF形式でダウンロード (406K) -
綿,ポリエステル,改質ポリエステル衣服を身体左右に同時着用して菅井 清美, 中島 利誠1989 年 45 巻 5 号 p. 206-213

ジャーナル フリー衣服気候と感覚におよぼす衣服素材の影響を,身体左右に綿,ポリエステルあるいは改質ポリエステルを同時に着用して検討した。暖かい環境で,環境水蒸気圧のみを変化させ,背部の皮膚と衣服上の温度と湿度,口腔温,体重損失,着用感覚を2時間測定した。
その結果,被験者はそれぞれ固有の生理的応答パターンを示した。衣服気候の温度変化は,綿/ポリエステル系では環境湿度の上昇,下降期間とも,ポリエステルより綿側の方が大きかった。湿度の下降期間では,ポリエステル間でも差がみられた。温度の降下は通常のポリエステルより改質ポリエステル側の方が大きかった。衣服素材特牲によっておこる着用感覚の差は,特に衣服の濡れ感・湿り感においてみられた。身体左右に異なる素材の衣服を着用して行う一対比較は,わずかな環境変化によっておこる衣服気候や感覚を評価するのにたいへん有用である。抄録全体を表示PDF形式でダウンロード (463K) -

ジャーナル フリーTactile soft-feeling (“SOFTNESS”) is one of the most important factor for the quality of underwear fabrics both for experts in the fabric producing factory and also for consumers, that is, the highest softness is closely related with the higher quality.
Firstly, the experts' group and consumers' group judged subjectively the softness for selected 203 samples by grading the feeling using the number corresponding to the intensity of feeling, form HV=1 (weakest) to HV=10 (strongest). Then these grading numbers were correlated with primary hand values of the fabric to explain what the softness feeling is.
When the mean values in each group are correlated, the good agreement between evaluations in two groups was observed. This implies that these two groups have a common criteria for the softness evaluation. This suggests the importance of evaluating the softness by the objective formula derived based on the mean values of judges because of existing within-group variation in the evaluation.
Secondly, the subjective quality values were correlated directly with mechanical parameters of those fabrics and the equation for obtaining the quality value was derived. It has been proved that the prediction ability of this equation is rather higher than the individual judges' judgment.抄録全体を表示PDF形式でダウンロード (662K) -

ジャーナル フリーAlthough the visual judgment of clothes generally depends on the verbal exprssion, the variance of standard for judgment has always been a trouble some problem. Then, purpose of this paper is to analyze the construction of judgment and to establish the common standard.
Valuers were classified to a professional and a contrast non-professional group. They judged twenty clothes by employing three pairs of words, for judgment.
Considering these results, we obtained following conclusions.
1) By variance-analysis, some combinations of the paired words and the clothes, in which the significant difference was observed in both valuers groups, were studied. We found that the professional group had (1) high coincidence and (2) many definite judges for each paired words.
2) Then, by studying the standard ot judgment in the professional group, we found that they judged clothes paying attention to some factors. These factors were classified and summarized to a table.
If these factors were employing as the standard of judgment which was made more acculately by adding the new paired words, objectivity of the visual expression of clothes and efficiency of training on the clothes judgment would be accomplished.抄録全体を表示PDF形式でダウンロード (656K) -

ジャーナル フリーIt is quite necessary to have informations on the relation between physical properties of mattresses and sleep comfort in order to design the ideal advanced bedding system. In this paper, subjective ratings for both sensation and the preference at initial sleep for each 14 types of mattress have been investigated by Sheffe's paired comparison (modified by Ura). The relation between preference ratings and the multiple compressive properties of mattresses has been also formulated.
The results were mainly as follows:
1. The correlation coefficients between overall comfort rating and the sensation of hardness suggested that the panels were needed to be classified into a few groups which prefered the different types of mattresses.
2. The following multiple regression equations were given to overall comfort ratings for mattresses at initial sleep for each A, B, C and total group.
The equation YA indicated that the mattress prefered by A group had easy compressive surface layer and supportive under layer. This agreed with the characteristics of the ideal bed recommended by Kohara. The equation Yc indicated that panels in C group prefered thin and easy compressive, so-called “senbei” mattress.抄録全体を表示PDF形式でダウンロード (611K) -

ジャーナル フリーカップ法による透湿水蒸気の拡散機構の研究には透湿水蒸気圧の水平分布を明らかにしておく必要がある。そこで,穴を開けて透湿性を与えたプラスチック板でふたをしたカップを用いて透湿度,板面からの高さおよびカップの内径を変えて透湿水蒸気圧の水平分布を検討した。透湿水蒸気圧の水平分布は透湿度,板面からの高さおよびカップ内側壁からの距離には依存しないが,内側壁からカップ中心に向って1.5cmの間は外気の水蒸気圧に影響され,境界領域と考えられる。その結果,透湿水蒸気圧の垂直方向の分布から水蒸気の拡散を研究するには,カップの内径が少なくとも3cm以上必要であることが分かった。抄録全体を表示PDF形式でダウンロード (216K) -
