Abstract
A moisture holding material for blending with fill to form an engineered surface. The moisture holding material includes a first non-woven fabric coated in an aqueous superabsorbent polymer (SAP); a second non-woven fabric; fiber; and a fluff material that are chopped and applied topically within a surface, on various substrates including, but not limited to, rubber, sand, wood chippings, grass, soil, fiber, textile, clay or rock. A portion of the non-woven material is coated with SAP.
Claims20
A moisture holding fiber blend material comprising:
- superabsorbent polymer (SAP) coated non-woven fabric materials;
- untreated non-woven fabric materials;
- polymeric materials, including staple fibers and particles;
- and
- fluff, a natural and/or synthetic cotton-like material that is generally a fibrous mass of natural and/or synthetic fibers, intertwined and entangled to form a cohesive unit of fibers and held together by interfacial friction and surface energy,
- wherein the moisture holding fiber blend material is blended as a particulate mixture that may be applied to a substrate or mixed with a substrate to form an engineered earthen recreation and sports surface that requires minimal irrigation and maintenance.
