Benefits of technology

This patent describes a new coating for artificial turf infill that has several benefits. The base coating protects the natural fibers, keeping them together, which makes the infill last longer. The inclusion of a green pigment can make the infill look more realistic. The use of a binging agent, a type of polyurethane polymer, can provide openings in the coating that improve its durability and mechanical properties, and can also cool the infill.

Problems solved by technology

The physical contact between different natural fibers will however cause defects.
There would be small surface defects.
This may reduce the heating of the artificial turf infill.

Embodiment Construction

[0086]Like numbered elements in these figures are either equivalent elements or perform the same function. Elements which have been discussed previously will not necessarily be discussed in later figures if the function is equivalent.

[0087]FIGS. 1 and 2 illustrate the manufacture of an artificial turf using an artificial turf carpet and artificial turf infill. In FIG. 1 an artificial turf carpet 100 can be seen. The artificial turf carpet 100 comprises a backing 102. The artificial turf carpet 100 shown in FIG. 1 is a tufted artificial turf carpet in this example. The artificial turf carpet is formed by artificial turf fiber tufts 104 that are tufted into the backing 102. The artificial turf fiber tufts 104 are tufted in rows. There is row spacing 106 between adjacent rows of tufts. The artificial turf fiber tufts 104 also extent a distance above the backing 102. The distance that the fibers 104 extend above the backing 102 is the pile height 108. In FIG. 1 it can be seen that the a...

Abstract

The method includes providing a base composition including a natural fiber, at least one first type of pigment, and a fluid binding agent. The fluid binding agent includes at least one type of polymer component. The natural fiber includes any one of hemp fiber, burlap fiber, sisal fiber, elephant grass, cotton, coconut fiber, and combinations thereof. The method further includes mixing the base composition. The method further includes adding water and a catalyst to the base composition during the mixing of the base composition to cure the fluid binding agent and the at least one first type of pigment into a base coating of the natural fiber.

Description

FIELD OF THE INVENTION[0001]The invention relates to artificial turf and methods for the manufacture of artificial turf infill.BACKGROUND AND RELATED ART[0002]Artificial turf or artificial grass is surface that is made up of fibers which is used to replace grass. The structure of the artificial turf is designed such that the artificial turf has an appearance which resembles grass. Typically artificial turf is used as a surface for sports such as soccer, American football, rugby, tennis, golf, for playing fields, or exercise fields. Furthermore artificial turf is frequently used for landscaping applications.[0003]Artificial turf may be manufactured using techniques for manufacturing carpets. For example artificial turf fibers which have the appearance of grass blades may be tufted or attached to a backing. Often times artificial turf infill is placed between the artificial turf fibers. Artificial turf infill is a granular material that covers the bottom portion of the artificial turf...
