Abstract

Artificial turf (AT) made of polyethylene (PE) fibers needs no water. It can replace natural turf. The major disadvantage of the AT is the electrostatic charge (ESC) generated from friction with other materials. ESC has bad healthy effects on human beings. The present study investigates the possibility to reduce ESC generated from friction of rubber soles by blending AT by polyamide (PA).
 
The experiments reveal that ESC generated on the surfaces of rubber and AT decreased with the increase of PA content. Water wet contact-separation of AT and rubber, displayed lower ESC values than that shown for dry contact. It seems that the presence of water as good conductor facilitated ESC transfer. When the applied load increased ESC decreased. That can be due to the area of contact of the PA strings and AT increased with the increase of the load, where positive and negative ESC neutralized each other. AT fibers blended by PA strings displayed lower ESC values at water wet sliding. ESC drastically decreased with increasing the applied load because the area of contact of the PA strings with AT increased. Finally, it can be proposed to blend AT by PA strings to decrease the generated ESC after contact-separation and sliding. PA content of 50 wt. % relative to the AT showed the favorite results.
