上側と下側が異なった厚さの二種類の掛布団 (掛布団A : 厚さが中央部より上側が12cm, 下側が5 cm。掛布団B : Aとは逆に上側が5 cm, 下側が12cm) を着用して環境温度18℃において夜間睡眠をとった場合に, 成人女性の核温がどのように変化するかについて実験を行った。被験者は, 半袖のシャツと半ズボンを着用してベッドで眠り, 午後10時から翌朝の6時まで掛布団AかBを掛けて眠った。

　主な結果は, 核温が掛布団Bでは, 入床後, 速やかに低下し睡眠中低く保たれたことである。すべての被験者は, 掛布団BをAより快適なものとして好んだ。これらの知見を温熱生理学の立場から論じる。

  We proposed the method of measurement of swinging properties for clothes when wearing. The fluorescent agent has radiating character under the black light, which is applied to the method of measurement in this report. At first, radiating characters for various threads, clothes, seals and beads with fluorescent agent under the black light were investigated experimentally. And next, two types semiutight skirts with 45cm and 65cm for the length were made of gray flannel clothes, and were sewn the white thread with fluorescent agent into these skirts. Finally, the wearing test using these skirts were carried out under the black light, for example, the panels worn these skirts and raised their right legs slowly to give the swing motions for skirts, and then the swinging properties were recorded as the continuous locus of the radiants.

  The extent of fatigue of the workers in the tomato-vinyl-green-house was investigated on the spot. Their fatigue, as a result, were easy to become chronic, although the daily works inside the vinyl-house are not so stressed. Furthermore the sunburn accelerated the fatigue becoming chronic.

  Then 6 type of UV-cutting fabrics with different finishings and materials were screened to choose the one suitable for the working clothes, which relieves the fatigue by preventing the sunburn. One type of UV-cutting fabric made of 100 % cotton with knitted texture possessed the high regain and smart air permeability. Also the fabric shielded the UV-ray at high rate, and the shielding effect was kept after repeated washing.

  A working clothes was made from the fabrics above mentioned, and clothes from non-finished cotton fabrics, UV-cutting polyester fabrics and normal cotton fabrics were also prepared for comparison. The temperature and humidity within clothes with cotton UV-cutting fabrics could be well controlled and was comfortable for the worker, while the clothes with UV-cutting polyester fabric was less comfortable due to the humidity increase inside the clothes in spite of the comparative UV-cutting property.

  Thus the wearing environment during work in the vinyl-green-house can be improved by choosing the UV-cutting fabrics with suitable material for working clothes.

  Air porosity is an important performance of clothing material to consider the comfortable clothing.

  Air porosity is estimated by a calculation formula. A suitable experiment method has not been found. Now that we develope an easy measurement method to be able to determine the correct air porosity. The method consists of two ways by means of measuring cylinder and syringe.

  Both methods have a good sense of sigth and are the effective teaching materials, so that they are able to be applied to an actual teaching load. Particularly, the method using measuring cylinder is very accurate and easy to operate.

  Air permeability is one of the important characters of textiles and clothing materials in considering comfortability of clothing. Many simple measurement methods of air permeability have been reported, but each has it's own problem. Now we have developed a simple measurement method to be able to determine easily the correct values.

  With this method, the air permeability is determined by the use of volume of effluent air in a baloon.

  It is very accurate and good visual method with easy operation. Moreover, it is effective teaching materials and possible to use in the actual teaching.

  The compressive properties of the arms were studied in healthy nomal subjects (20 males and 20 females). The used compactor was a circular surface 3cm² in area, and the maximum of the compressive force was 100gf/cm². The experiment was carried out at rest and tonus, and the compressive properties of the arms were measured at 12 points, which were the medials and lateral sides of bilateral upper arms, forearms and wrists. The compressive stress-strain curves of these points were compared.

  The compressive-recovery curves of the arms showed hysteretic mechanical properties. The arms at rest were more compressible than those at tonus ; and the medial sides were more compressible than the lateral ones. The compressibility was high in order of the wrists, forearms and upper arms, and there was no difference between compressivilities of the female arms and male arms.

  Being made model experiments of yunoshi process in shrinking for Kimono, residual tensile strain and bending rigidity of silk crape clothes when stretched in warp and filling direction of clothes shrunk at their maximum by pre-washing (huriarai) under steaming were discussed.

  1) It's sufficient to set in shape of residual tensile strain of clothes due to loading by steaming at 98℃ for 60sec.

  2) Residual tensile strain of clothes due to loading in filling direction is larger than that of warp direction, in case of filling creping clothes. Here, in former tensile loading, the width of clothes in perpendicular to loading direction (warp) becomes shorter, but in latter tensile loading, the width of clothes in perpendicular to loading direction (filling) becomes longer a little.

  And in case of Habutae, it does not almost generate residual tensile strain due to loading.

  3) Changes of density, thickness and weight of clothes due to tensile load under steaming depend on residual tensile strain mentioned in above 2). Above all, as residual tensile strain due to loading when steaming in filling direction is large, these three properties of clothes in warp direction decrease to a high degree. Accordingly, variations of properties for clothes due to yunoshi treatment look forward to the degree of tensile extension in filling direction of clothes when steaming.

  4) With still more increase of tensile load in steaming, bending rigidity of clothes grows larger. This is caused by next ① and ② come about when loading to clothes under steaming, ① the contact area both warp and filling yarns of clothes become langer, and ② the hardening of the very filling and warp yarns of clothes.
