摘要： PURPOSE: A three dimensional network structure is provided to be applied to a cushion, a sofa, a bed(mattress), and a chair. CONSTITUTION: A three dimensional network structure has enhanced expansion ratio with respect to the rate of shear when the diameter of the cross section of a filament is D2 by extruding thermoplastic resin from a tube with an intraluminal diameter of D1=1.0 MM and a length of 10 mm at 190 deg. C and cooling the extruded filament. The expansion ratio with respect to shear speed 24.3 sec-1 is 0.93-1.16. The expansion ratio=D2/D1 with respect to shear speed 608.0 sec-1 is 1.0-1.2.
