Abstract

The invention relates to an antistatic polyamide elastomer spun yarn and a processing method thereof. The processing method of the antistatic polyamide elastomer spun yarn comprises the following steps: S1, melting an antistatic polyamide elastomer, and spinning the fused antistatic polyamide elastomer to obtain primary spun yarn; and S2, drafting the primary spun yarn by 4-6 times to obtain the antistatic polyamide elastomer spun yarn. According to the technical scheme, the antistatic polyamide elastomer is melted, the melted antistatic polyamide elastomer is spun, the obtained primary spun yarn is drafted by 4-6 times, and based on drafting of the primary spun yarn, the number of molecular chains, bearing external tension, of the antistatic polyamide elastomer spun yarn is increased, the breaking strength is remarkably improved, the elasticity is better, the low-temperature resistance is improved due to drafting of the primary spun yarn, the antistatic polyamide elastomer spun yarn has yellowing resistance, antistatic property and good water absorption property, and the fabric woven by the antistatic polyamide elastomer spun yarn is light in weight per unit area.
