An artificial turf can include a base material; a plurality of piles imitating turf leaves erected on the base material; and a filler layer formed by a filler material being filled between the plurality of piles, wherein the filler layer includes a water retaining layer and a mineral having calcium carbonate as a major component.

Artificial grass (100, 200, 320) with good fire-retardant performance including its manufacturing process (300) is disclosed, particularly to be used for indoor applications. The fire retardant, particularly of halogen-based type (311), is incorporated within the artificial fiber filaments (101, 201, 301). The backing (102, 202, 302) onto which the artificial fiber filaments (101, 201, 301) are attached, may also be provided with a fire retardant.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.

A method for producing an artificial turf fiber, comprising: preparing a core polymer mixture from a core polymer and a thread polymer forming beads within the core polymer; coextruding the core polymer mixture with a cladding polymer component into a monofilament, the core polymer mixture forming a cylindrical core, The cladding polymer component forming a cladding encompassing the core with a non-circular profile; quenching the monofilament; reheating the quenched monofilament; stretching the reheated monofilament to deform the beads into threadlike regions; and providing one or more of the stretched monofilaments as the artificial turf fiber.

Artificial turf for use with an artificial turf system, which may also include a base layer and a support layer. The artificial turf comprising a backing supporting pile tufts of between ¼″ to 4″ in length, in position on its upper surface. The backing may comprise a porous synthetic foam or backing sheet. A filler of particles shaped to have no sharp edges and of substantially equal size are interspersed over the backing and about the tufts up to at least half thick length. The artificial turf substantially retains its resiliency, porosity and equal density throughout.
