Linear friction stud slide & stud deceleration value

Yarn type is the key component for stud slide and and stud deceleration, but pile height is also significant.

General Characteristics Dow Products Qualities Results
Yarn Type

Similar to rotational resistance the elastic properties and the fibrillation resistance of the yarn are decisive for stud slide.

The best performance is obtained by achieving the right balance between stiffness, friction and resiliency. The more the elastic properties of the yarn, the better the resiliency to achieve optimal stud slide and deceleration value.

Dow can develop modular products that combine polyethylene resins, such as DOWLEX™ Polyethylene Resins or ELITE™ Enhanced Polyethylene Resins, with polyolefin elastomers Flexibility and sliding (skin friction) properties of fibers Achieve the required performance
Pile Height

Similarly to rotational resistance, pile height can have an impact on stud slide, as the higher the pile the greater the chances that a player can entangle in the blades of grass during a tackling or sliding effort.

Early artificial turf systems had low piles with very bad sliding and friction characteristics that caused high risk of injury to players.

A certain pile height is therefore required to make sure that sliding mainly takes place on the yarn, avoiding players' friction with the sand and rubber infill material underneath the pile, which would reduce stud slide, increase stud deceleration and cause skin friction and abrasion.

Your Dow product choice for yarn type will contribute to desired pile height.
