The Purpose of the experiment in this paper is to make clear the relation between pressure and strain of volume, examine compressibility and compressional resilience in blended fibre's lump of several kind's fibre by the aid of improved equipment, trial manufactured equipment in a series of this paper, registered as Patent Number 486847 in Japan Patent Office. The experiment of this thesis is in force under the pressure from 0 (kg/cm^2) to 5 (kg/cm^2) at the each stages of the increase and decrease in pressure. In order to keep column of mercury from scattering depend on the pressure, the author concentrated special attention on the increase and decrease of pressure from 0 (kg/cm^2) to 0.05 (kg/cm^2) in the early stage. As the several kind's fibre of test pieces, Viscose Rayon (Crimped Dull), Kanekalon (N-Type), Polynozic, Bemberg and Pylen have been used. The cut-length and fineness of the test pieces is 76 milimeters and 3 deniers. All of thease fibres is not straight filament, but crimped fibre. As the blended fibre of the test piece, Viscose Rayon (crimped dull)×Kanekalon (N-Type), Viscose Rayon (crimped dull)×Pylen, Viscose Rayon (crimped dull)×Bemberg, Viscose Rayon (crimped dull)×Polynozic, Kanekalon (N-Type)×Pylen, Kanekalon (N-Type)×Bemberg, Kanekalon (N-Type)×Polynozic, Pylen×Bemberg, Pylen×Polynozic and Bemberg×Polynozic have been used. The percentages of blending in each blended fibres is 30,50 and 70 percentages. The theoretical equation of strain of volume Ev.p (%) under pressure P is following, Ev.p (%)=(ΔVp)/(Vo)×100 (%) but, ΔVp (cm^3)=πr^2・l (cm^3) Here Vo (cm^3) represents the volume of fibre under the pressure P=0 (kg/cm^2) at the moment : ΔVp (cm^3), discharged air quantity under the pressure P (kg/cm^2) at the moment : r (m/m), radius of hole of glass capillary tube : l (cm), displaced length of column of mercury into the glass capillary tube. also, The theoretical equation on the specific gravity of blended fibre M (g/cm^3) is
