Abstract

The present work aims to develop the performance and the comfort of the polymeric textiles to enhance the quality of the clothes. It is known that one of the measures of the comfort is the generation of electrostatic charge (ESC) on the surface of the textiles when they rub other materials, human hair and skin. As ESC increased, the comfort of the clothes decreased. In the present work ESC generated from contact-separation as well as sliding of polymeric textiles on cotton is discussed. Test specimens of composites containing polyester (PET) and polyamide (PA) textile fibers were blended by 2.0 wt. % carbon fiber (CF) and tested by contacting cotton textiles under 10 N load. Ultra surface DC Voltmeter was used to measure ESC of the tested textile composites.
 
It was found that ESC generated on PET/PA strings blended by CF from the contact-separation and sliding on cotton drastically decreased with increasing PET content. PA strings displayed positive ESC, while PET showed negative one, then the zero value of ESC was detected at 40 wt. % PET content. Composites blended by 2.0 wt. % CF showed significant reduction in the values of ESC due to their conduction of ESC from one surface to the other. Besides, cotton gained zero ESC at 30 and 40 wt. % PET at contact-separation and sliding respectively. Finally, sliding of the tested polymeric textiles against cotton displayed relatively higher ESC values than that observed in contact-separation. And the zero value of ESC was observed at 22 wt. % PET, while composites blended by 2.0 wt. % CF showed zero value detected at 40 wt. % PET.
