Abstract

The present invention discloses an antistatic nylon fibre and its preparation method. Said antistatic nylon fibre is made up by using (by weight portion) 89-96 portions of nylon 6 chip, 3-10 portions of polymer type antistatic agent and 1 portion of adjuvant. Its preparation method includes the following steps: uniformly mixing and stirring the above-mentioned materials for 30 min, then under the condition of nitrogen gas protection placing the obtained mixture into a melt spinning machine to make melt spinning at 265 deg.C-275 deg.C.

Description

technical field [0001] The invention relates to a nylon fiber, in particular to an antistatic nylon fiber and a preparation method thereof. The antistatic nylon fiber is suitable for making antistatic fabrics, antistatic clothing, antistatic woven bags, and antistatic packaging bags. Background technique [0002] U.S. Patent 6072001 discloses a kind of antistatic nylon fiber material based on high molecular weight polyethylene glycol and maleic anhydride modified polyolefin as antistatic agent, and its preparation process is high molecular weight polyethylene glycol and maleic anhydride modified polyolefin It is mixed with nylon chips, then extruded and spun to obtain antistatic nylon fibers. The source of antistatic agent that this method adopts is abundant; But, its antistatic principle of this method adopts antistatic agent belongs to hygroscopic type, so antistatic effect is limited, and its surface resistivity is 10 10 -10 12 Ω, especially un...
