Three-dimensional network structure and manufacturing method therefor

Abstract

It is provided that: a three-dimensional network structure that exhibits excellent cushioning property and excellent compression recoverability after thermal compression at a usage environmental temperature; and a manufacturing method therefor. A three-dimensional network structure having a three-dimensional random loop-bonded configuration and comprising a continuous filament made from a thermoplastic resin composition, wherein the thermoplastic resin composition contains 70% by mass or higher of a polybutylene adipate terephthalate resin, and an enthalpy of an endothermic peak in which a DSC curve regarding the continuous filament measured by using a differential scanning calorimeter has a minimum value in a range from 30° C. to 70° C. of 2.5 J/g or lower.
