Artificial turf with textured hydrophilic fibers

Abstract

An artificial turf system for installation over a receiving surface is described. The artificial turf system comprising: a sheet member made of a flexible material, the sheet member defining a first surface for interfacing with the receiving surface and a second surface; primary yarns made of straight fibers backstitched in and threaded through the sheet member and upwardly extending from the sheet member to a first elevation; and secondary yarns made of textured fibers backstitched in and threaded through the sheet member and upwardly extending from the sheet member at a second elevation less than the first elevation which is caused by a difference in texture between the primary yarns and the secondary yarns, wherein the secondary yarns are more rigid than the primary yarns, and wherein the primary yarns and the secondary yarns have ends which are cut after being threaded through the sheet member.

AI Technical Summary

Benefits of technology

The patent describes a method to make yarns more rigid than the primary yarns. This is achieved by improving the material and process used to make the secondary yarns. The technical effect of this is better control and stability during processing, resulting in stronger and more reliable yarns.

Problems solved by technology

Even though the rubber granules and / or sand used in modern artificial synthetic turf tend to contain lower quantities of harmful substances, such as metal (e.g., lead and zinc), inorganic and organic compounds, it may significantly increase health problems for those playing / walking on it, it may significantly increase the surface temperature above the surface covering panel and it may lead to some other environmental problems.

The infill also becomes compacted with time affecting directly shock absorption and traction of the artificial synthetic turf to the detriment of the players.

Therefore, the straight fiber support, traction and shock absorbent characteristics are not optimized.

However, according to this configuration, the straight fiber support, players traction and shock absorbent characteristic are not optimized.
