Abstract
Generation of electrostatic charge (ESC) of textiles controls the quality and comfort of clothes.  The present work discusses the ESC generated from the contact-separation and sliding of polyamide and polyester strings blended by carbon fibers on cotton. Test specimens of composites containing both polyester (PET) and polyamide (PA) strings were prepared and tested by contact-separation and sliding under different loads against cotton textiles. The ESC generated on the surfaces of the tested materials was measured.
 
The experimental results revealed that at contact-separation of PET with cotton, ESC generated on the surface of PET blended by CF decreased with increasing CF content. PET free from CF showed the highest negative ESC values. It seems that CF facilitates the conduction of ESC from PET to cotton. At sliding, ESC recorded relatively higher values than that observed at contact-separation, where the effect of CF was significant. PA strings contacting cotton textile displayed relatively lower values than that observed for PET. That behavior can be attributed to that PET strings had fine fibers that increased the area subjected to ESC, while the surface of PA strings is smooth with no fibers. Finally, sliding of the PA strings blended by CF against cotton displayed relatively higher vales at 100 % PA than that observed in contact and separation.
