Abstract
An object of the present invention is to provide a three-dimensional network structure which has high hydrolysis resistance and thus degradation of resin due to moisture in the air is prevented in long-term use. The three-dimensional network structure includes a three-dimensional random loop shaped and bonded structure including a linear continuous fiber, wherein the linear continuous fiber includes a resin composition, and the resin composition includes a polyester-based thermoplastic elastomer and a phosphate glass. The phosphate glass preferably contains P2O5, SiO2, ZnO, and at least one selected from the group consisting of an alkali metal oxide and an alkaline earth metal.
Claims3
A three-dimensional network structure comprising a three-dimensional random loop shaped and bonded structure comprising a linear continuous fiber,
- wherein the linear continuous fiber comprises a resin composition, and
- the resin composition comprises a polyester-based thermoplastic elastomer and a phosphate glass, and
- the molar ratio of phosphorus atoms to silicon atoms (P/Si) in the phosphate glass is 1 to 15.
