The purpose of the research in this paper is to make clear the behaviour of temperature dependence on the compressional behaviour of each single fibre's lump. Where, the author used trial manufactured apparatus for this experiment. This trial manufactured apparatus is introduced in previous thesis, Part twelve. And this trial manufactured apparatus is Japanese Patent Number 486847. The author searched for relation among many important factors. As these important factors, pressure P (kg/cm^2), strain of volume percentage Ev.p (%), percentage of critical strain of volume in theory E'v.p (%) and temperature T (℃) is taken into the consideration. As a range of pressure P is from O (kg/cm^2) to 5 (kg/cm^2) through increasing and decreasing pressure. As the single fibre's lump of the test piece in this experiment is the following. Namely, Viscose Rayon (Crimped Dull) 3 deniers x 76m/m, Nylon 3 deniers x 70m/m and Beslon 3 deniers x 55m/m have been used. The arrangement of all these single fibre's lump is case of non-parallel in direction of single fibre's arrangement. As a number of times in the hysteresis of increasing and decreasing of pressure adopted case of the first time in the hysteresis. As a first step, range of temperature set within the limits from 10℃ to 80℃. The experiment of behaviour of temperature dependence was tried by steps of 10℃ of temperature each. Before the experiment the author made control of fibre's weight into the gum ball, carding of fibre's lump and moisture regain of each fibre's lump as a test piece in this experiment. Also, before the experiment the author must obtain these factors as a measuring value for calculating the strain of volume percentage Ev.p (%) and percentage of critical strain of volume in theory E'v.p (%). These factors is made by ten factors : Wt (g), total weight (substituted by water) : Vt (cm^3), total volume (substituted by water) : Wr (g), weight of gum ball : {Wr+Wf} (g), weight of {(gum ball)+ (fibre)} : Wf (g), weight of fibre : Vr (cm^3), volume of gum : Vo (cm^3), volume of fibre under the pressure P=0 (kg/cm^2) : Vf=Wf/σf (cm^3), real volume of fibre : T (℃), temperature of water at the moment : σw/t (g/cm^3), the specific gravity of water under the temperature at the moment : The results of these experiments of single fibre's lump was investigated through the relation that is made by the following each graph. Namely, this is a P∿Ev.p curve. This is a relative curve between pressure P (kg/cm^2) and strain of volume Ev.p (%). And this is a relative curve in that time of each step from 10℃ to 80℃ in temperature through the test pieces. Here, the test piece is Viscose Rayon, Nylon and Beslon. Further, this graph is a drawing of the development tendency between temperature T℃ and difference of strain of volume Ev.p (%)-D- in that time of pressure P=0 (kg/cm^2) and 5 (kg/cm^2) through the test pieces, Viscose Rayon, Nylon and Beslon. And the author found that these investigated results in this experiment had not contradictory points. Thus, these experimental results which were obtained in the way described above proved the rationality.
