Quantitative measurement of fibre is not easy to conduct chiefly because of its indefinite shape. Cylinder system and gum ball (gum balloon) method are most widely employed. Of these two, the former is not fully applicable because of the friction produced between the fibre and the inner wall of the cylinder, and the latter, because of the leackage of air through the gum ball. The important condition required for the apparatus is ever to exactly record the change of stress imposed on the fibre. The methods mentioned above do not satisfy this condition. In order to get over this difficulty, the author wishes to present you a new equipment as is explained in this paper. This new apparatus is a new apparatus of trial manufacture for measuring compressional behaviour of fibres. And the purpose of the research in this paper is to make clear for measuring the behaviour of temperature dependence on the compressional behaviour of each fibres. This new apparatus of trial manufacture for measuring compressional behaviour of fibres show Figure I. In this Figure I, new apparatus is made from five chief parts. Namely, this new apparatus is made from five chief parts from A, B, C, D and E. Here, A is a part of regulating pressure. B is a section of regulating temperature. C is a part on the tank of increasing and decreasing pressure. D is a section of refrigeratory. And E is a part of recording the movements of the column of mercury in the glass capillary tube for calculate changeable quantity of volume through increasing and decreasing pressure. Where, into this new apparatus, the parts of three in A, D and E is the very same part in the old apparatus. Accordingly, the author wishes to present you a new apparatus as is explained on the parts of B and C in this paper. The part of B is a part of precision constant temperature circulational apparatus. And as the type of this apparatus in part of B is MTU-3 type and LCH-7D type. Here, MTU-3 type is precision constant temperature circulational apparatus in range of plus in temperature. There-fore, as the circulate liquid is possibility to use water. Also, LCH-7D type is precision constant temperature circulational apparatus in range of minus in temperature. Consequently, as the circulate liquid is impossibility to use water. Accordingly, as the circulate liquid use the Methanol. This range of minus in temperature is temperature less than -20℃, as a temperature in experiment of this paper. Also, these MTU-3 type and LCH-7D type of precision constant temperature circulational apparatus is made by Advantec Toyo Co. Ltd. in Japan. In order to build up the ability of constant temperature, the author did renewal direct current hydroelectic resources 4-F (8-F) type of regulator of temperature. And the author adopted MTU-3 type and LCH-7D type of precision constant temperature circulational apparatus in this paper. O. in cipher into [Fig. I] is a discharge pipe of circulate liquid and an intake of circulate liquid. The part of C is a part on the take of increasing and decreasing pressure. And this part of new apparatus show by cipher of -C-into [Fig. I]. This is most important part on the stainless steel tank of increasing and decreasing pressure. And this part of -C- is highest original or creative part into the apparatus of trial manufacture for measuring behaviour of temperature dependence on the compressional behaviour of fibre's lump in this paper. Here, this part of stainless steel tank have the part on the upper and under lid of stainless steel, tank in duplication or doubleness, the feeling of heat or temperature, peep window for look the interior or inner part in the stainless steel tank of inside in the doubleness tanks from outside, the space to pass through the precision constant temperature circulational liquid, and the others many important sections. These important many sections is explicated into [Fig. I], Accordingly, the author wishes to see reader [Fig. I] of the new apparatu
