The trampoline (1) has a jumping mat (3) fixed on a frame structure (2) by an elastic element. The jumping mat is formed by low-stretch yarns made of textile fabrics. The low-stretch yarns form a string, where a two-dimensional structure of the textile fabric is formed by the string. The low-stretch yarns are made of aramid or para-aramid, particularly Levlar(RTM: Para-aramid synthetic fiber) or twaron, polyethylene, Dyneema(RTM: Ultra-high-molecular-weight polyethylene), carbon, and Vectran(RTM: aromatic polyester). |
