Decreasing the electrostatic discharge generated from friction of polyester and polyamide sing carbon fiber Verringerung der durch Reibung von Polyester und Polyamid erzeugten elektrostatischen Entladung mithilfe von Kohlefasern

The present work discusses the voltage difference as a measure for electrostatic charge generated from the contact-separation and sliding of polymeric textiles on polyamide textile. It is proposed to blend polyester by carbon fiber to decrease the electrostatic charge generated on the contact surfaces. Because polyester acquires a negative charge and polyamide gains a positive one, carbon fiber is proposed to conduct the negative electrostatic charge from polyester to polyamide and conducts the positive one from polyamide to polyester, so that the resultant electrostatic charge decreased. The effect of carbon fiber to decrease the electrostatic charge depends on its area of contact, interaction, and distribution with polyester. Polyester double weaved by carbon fiber showed the lowest voltage. Based on those observations, it can be recommended to use double weaves of carbon fiber with polyester. The reduction in voltage was relatively lower for braided polyester by carbon fiber than that detected for double-weaved polyester by carbon fiber.
