ARTIFICIAL LAWN AND ARTIFICIAL-LAWN STADIUM

摘要

PROBLEM TO BE SOLVED: To prevent a line from bending due to the elongation of an artificial lawn.;SOLUTION: In the artificial lawn, in which piles 2 are implanted to a base fabric 1 and which is positioned and placed on a substrate by filling a granular material among the piles, elongation in the case of load in 196 N/50 mm width (20 kgf/50 mm width) reaches 25% or less at a measured value by a tension test stipulated in JIS L-1096 (sections among chucks of 300 mm and a rate of pulling of 100 mm/min) in elongation in the 45° direction to the pile implanting direction of the base fabric 1.;COPYRIGHT: (C)2002,JPO
