Document Type and Number:
WIPO Patent Application WO/2023/190964
Kind Code:
A1
Abstract:
The present invention provides a three-dimensional net-like structure having excellent cushioning properties and excellent compression recovery properties after thermal compression at the use environment temperature, and a manufacturing method for the same. Provided is a three-dimensional net-like structure that is formed from a continuous filament formed from a thermoplastic resin composition and has a three-dimensional random loop bonded structure, wherein the thermoplastic resin composition contains at least 70 mass% of polybutylene adipate terephthalate resin, and in a DSC curve of the continuous filament measured using a differential scanning calorimeter, the enthalpy of an endothermic peak having a minimum value in the range of 30-70°C is at most 2.7 J/g.
