PURPOSE:To obtain a high-quality artificial rush extremely similar to natural rush, having tension, rigidity, proper elasticity, excellent handle and heat insulating properties, providing touch cool in summer and warm in winter. CONSTITUTION:This artificial rush is a linear hollow foam having a shell and a hollow part, comprising a thermoplastic resin and the shell has a modified cross-sectional shape and a great number of striped projections and dented parts extending in the axial direction on the surface. Or, artificial rush is a linear hollow foam having a shell and a hollow part, comprising a thermoplastic resin and the shell has a modified cross-sectional shape and fibrillated. Further, artificial rush is a linear hollow foam having a shell and a hollow part, comprising a thermoplastic resin and the shell has a section of a shape of plural connected block-like materials with a modified cross section and cracked parts at least on the surface. |
