All artificial grass yarn falls into the category of either slit film or monofilament. The obvious questions is which one is the best choice? Slit film is made exactly as the name implies. It is extruded as a solid sheet and slit into smaller ribbons or tapes. Therefore, slit film does a good job of immulating wider blade grass when viewed from a distance. Slit film also has the advantage that it can be extruded at higher output rates than monofilament; therefore, a lower cost. The disadvantage is a slit film yarn will always be basically a flat yarn. Most real, wider-blade grass viewed up close has a spine that cannot be immulated with a slit film yarn. This spine also acts as a support and provides it with rigidity. Monofilament is extruded where each individual fiber is extruded out of an individual hole. This allows the manufacturer to make a variety of cross sections or shapes. This may lead to higher cost due to lower output rates; however, it makes a yarn that is pound per pound superior to a slit film yarn. It also makes a yarn that can be made to very closely copy the look and feel of real grass. The best example that people can relate to is a beam made of steel. A flat piece of steel does not have much rigidity or stiffness when compared to steel configured as an I beam. In our case the flat piece of steel would be a slit film yarn, and a monofilament could be extruded with a spine similar to the concept of an I beam. In summary, as a purchaser of artificial grass consumers should be aware that using a monofilament yarn may be slightly higher in initial cost. However, the resulting product can use different monofilament cross sections to maximize the properties that are required for their end use.
