Abstract

Artificial turf (AT) replaces natural turf because it needs no water. AT is made of polyethylene (PE) fibers, where electrostatic charge (ESC) generated from friction with rubber records relatively higher values that badly influences the health of human beings. AT is sprayed by water to decrease its abrasion action. In order to save fresh water, the present work investigate the possibility of spraying AT by salt water through testing its influence on the friction and ESC generated from contact/separation and sliding of rubber on AT.
 
It was found that at dry sliding of rubber on AT, friction coefficient represented the highest values. When AT was sprayed by water, friction coefficient showed values for salt water higher than that observed for fresh water. ESC generated from water wet contact/separation and sliding showed drastic decrease due to the good electrical conductivity that facilitated the ESC transfer between the two contact surfaces, where the values of ESC generated in the presence of salt water were lower than that measured for fresh water. It can be concluded that spraying AT with salt water can be promising solution to save fresh water and reduce ESC generated after both contact/separation and sliding of rubber on AT.
