Title:
ARTIFICIAL TURF CONTAINING GRANULE
Document Type and Number:
Japanese Patent JP2004300712
Kind Code:
A
Abstract:

To provide artificial turf containing granules, which has a good feel closely akin to that of natural turf, which hardly increases a temperature of its surface, which makes a player hardly feel a sense of fatigue, and which makes the player hardly feel a change in feeling not only because shock absorption hardly decreases but also because the outflow of soft granules and the like can be prevented, and a manufacturing method therefor.

In this artificial turf containing granules, at least two kinds of pile yarn, different in raw material and/or cross-sectional shape, are implanted in a base material, and rigid granules and soft granules are infilled between piles. The pile protrudes from the infilled granules; the pile, wherein a part protruded from the granules is curved or bent, and the erect pile are mixed together; and an L-value of the curved or bent pile is in a range of 25-60.
