Abstract
(EN)
Provided is an inexpensive three-dimensional net-shaped structure body having soft cushioning properties and little variations in hardness. The three-dimensional net-shaped structure body has a spring structure comprising a thermoplastic resin containing a mixture of a polypropylene-based copolymer (a) and a polypropylene-based copolymer (b), with loops being formed by continuous filaments being welded partially at random. The flexural modulus of the polypropylene-based copolymer (a) is different from the flexural modulus of the polypropylene-based copolymer (b).
(FR)
L'invention concerne un corps de structure en forme de filet tridimensionnel peu coûteux ayant des propriétés d'amortissement souple et de faibles variations de dureté. Le corps de structure en forme de filet tridimensionnel a une structure de ressort comprenant une résine thermoplastique contenant un mélange d'un copolymère à base de polypropylène (a) et d'un copolymère à base de polypropylène (b), les boucles étant formées par des filaments continus soudés partiellement au hasard. Le module de flexion du copolymère à base de polypropylène (a) est différent du module de flexion du copolymère à base de polypropylène (b).
(JA)
やわらかなクッション特性を有し、硬さのばらつきが少ない、安価な立体網状構造体を提供する。 ポリプロピレン系共重合体(a)とポリプロピレン系共重合体(b)の混合物を含む熱可塑性樹脂からなり、連続線条が部分的にランダムに溶着することによりループを形成したスプリング構造を有し、ポリプロピレン系共重合体(a)の曲げ弾性率は、ポリプロピレン系共重合体(b)の曲げ弾性率とは異なる、立体網状構造体である。
