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.
Claims36
A method of manufacturing artificial turf infill (202, 202′, 202″), wherein the method comprises:
- providing (800) a base composition comprising a natural fiber (500), at least one first type of of pigment, and a fluid binding agent, wherein the fluid binding agent comprises at least one type of polymer component, wherein the natural fiber comprises any one of the following:
- hemp fiber, burlap fiber, sisal fiber, elephant grass, cotton, coconut fiber, and combinations thereof;
- mixing (802) the base composition;
- adding (804) 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 of pigment into a base coating (502) of the natural fiber.
The method of manufacturing artificial turf infill of any one of the preceding claims, wherein the natural fiber comprises fibers less than 5 mm long, more preferably less than 1.5 mm long.
