Variations in color or texture between dye lots are highly possible in the manufacturing of synthetic turf. This month ASK JW will help you understand the importance of dye lots and how it can affect the appearance of your installation.

Blending of special ingredients made from colored pellets give the turf its traditional green color. Added chemicals in the mixture protects the fiber from the ultraviolet rays from the sun. These pellets are melted, blended and can be manufactured in different ways. They can be produced in thin sheets that are cut into strips or extruded through molds to produce fibers with a round, diamond, “W” cross-section. The final extruded results consist of blades that feel and act like natural grass. This completed mixture creates a dye lot.
