Abstract: PURPOSE: To obtain a fiber shaped body having uniform density, capable of stabilizing shape because of low residual strain of compression, hardly causing fatigue regardless of having lightness and softness and not aggregating. CONSTITUTION: This fiber mixture is composed of 20-60wt.% of a conjugate fiber A obtained by joining two kinds of different component thermoplastic polymers R1 and R2 in a range within the range of a weight ratio of (30/70) to (70/30) to form a core part and conjugating a thermoplastic polymer R3 having a melting point lower than that of a polymer having lower melting point between thermoplastic polymers R1 and R2 into the sheath part in a range of (20/80) to (60/40) weight ratio expressed by the formula R3/(R1+R2) and 40-80wt.% of a fiber B to which silicone resin is attached, having a melting point higher than that of the thermoplastic polymer R3. The fiber mixture improves also operability in production and has advantage which has not adverse effect on environment, because fluorocarbon is not used.
