Document Type and Number:
Japanese Patent JP6849454
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an artificial lawn of which a feeling of use changes only a little in different environmental conditions, such as under sunlight, rainy weather, after sprinkling water, etc.SOLUTION: An artificial lawn has a filler layer formed by filling a filler material between lawn-like yarns, the filler material of the filler layer comprising hard particles at a volume ratio between 1% and 50%, a palm filler material at a volume ratio between 5% and 45%, and elastic particles in the remaining portion. A temperature rise suppression effect brought about by evaporation heat may be obtained appropriately, because the palm filler material is contained at the volume ratio of 5% or more and moisture contained in the palm filler material evaporates when a temperature rises. On the other hand, aggravation of a feeling of touch and generation of an abnormal sound may be suppressed in rainy weather or when water is sprinkled on the artificial lawn, because the volume ratio of the palm filler material that holds moisture is kept at 45% or less. A change in a feeling of use may be kept small when the filler layer is dry and when moist, because the hard particles are contained in the filler layer at the volume ratio of 50% or less and the remaining portion of the filler layer is formed by the elastic particles.SELECTED DRAWING: Figure 1
