Abrasion: the damage caused by aggressive grooming equipment, heavy traffic with inappropriate footwear, improper vehicle traffic or infill materials that “irritate” or wear the yarn fiber surfaces. i.e. the reason cleats are mandatory garb for lacrosse, football, soccer, etc.
Anti-microbial: yarn or surface materials chemically treated to reduce the growth of common elements. Additives treat specific challenges such as bacteria, fungi, yeast, mold and mildew.
Anti-static: the ability of the fibers to disperse electrostatic charges and reduce the build-up of static electricity.
Backings: the materials that make up the underside of finished turf. The primary backing anchors the pile yarns, while the secondary backing provides extra dimensional stability and locks in the stitches.
Base materials: material that is used to construct the foundation over existing sub-base like native soil and under the final installation of synthetic surface material. May be made of gravel, mine rock, compactable aggregates and road base.
Cover: the degree to which the backing is concealed by the face yarn.
Dimensional stability: refers to the ability of the finished turf surfaces to retain its original size and shape.
Dry hand: the feel of the turf is dry to the touch.
Fiber: the fundamental component of turf. Turf fibers are made from nylon, polypropylene or polyethylene, colorants, stabilizers and other enhancements to provide features such as low-slip, UV protection, anti-static, anti-microbial in nature.
Flexural strength: the amount of bend or flex something exhibits against pressure.
Float: to float materials is to gently and smoothly spread them across the installation site. The objective is to leave the surface without ruts, bumps or bumps in the surface.
Glue down: the need to glue the turf materials to the flooring. Adhesives are selected for indoor or outdoor use, moisture, temperature variables, flooring and turf backing materials.
Hard edges: perimeter edges of a synthetic grass installation project that touch elements that will not or cannot move i.e. walkways, driveways, walls, patios, fences, buildings, foundations. The synthetic grass must be hand-trimmed to these edges.
Nylon: the primary product in a synthetic polyamide family widely used as a turf face yard in either BCF or staple yarn form.
Perforations: holes drilled or heat-punched into the backing of some synthetic turf materials. The perforations provide relief for watershed through the surfaces to accommodate percolation.
Permeable: how much liquid the surface will allow to flow through itself. Can be determined by a percolation test.
Pile: the visible surface of a finished product, often called the face or nap of the turf.
Polypropylene: synthetic, thermoplastic polymer used for molded items, sheets, films and fibers.
Relief cuts: cuts made into synthetic grass materials that will help alleviate any tension in the turf while positioning it and trimming it against hardedges that are curved or odd shaped.
Resilience: the capability of the turf to bounce back to its original appearance after being used.
Swale: typically used as an open channel to direct water runoff from rain and watershed.
Tuft bind: force required to pull a tufted blade out of the backing.
