Problems solved by technology

It can be seen that when the surface resistance is required to be low, it is impossible to directly add an antistatic agent, and an antistatic synergist must be added at the same time to solve the processing problem, and the permanent antistatic nylon elastomer material can only be added as an additive to In the fiber masterbatch, it cannot be melted and spun directly

Abstract

The invention relates to the field of macromolecular materials, and discloses a special conductive fiber material with permanent antistatic properties and melt direct spinning, including: 50-75% of multi-component nylon prepolymer with a molecular weight of 1500-2500, dibasic acid-terminated Polyester polyol or dibasic acid-terminated polyether polyol 35‑50%, the molecular weight of the polyester polyol and polyether polyol is 200‑3000, ethoxylated lauramide 1‑5%, ionic surface Active agent 1‑3%, lithium bisoxalate borate, 0.3‑0.5%, water 3‑5%. The material of the invention is polyester, polyether, amide block polymer, which can be directly melted and spun into conductive fibers, and can also be added to nylon or PET co-spinning as antistatic masterbatch to prepare antistatic fibers. It is characterized by permanent antistatic ability and no need to add antistatic synergist.

Description

technical field [0001] The invention relates to the field of macromolecule materials, in particular to a special conductive fiber material with permanent antistatic properties and capable of melt direct spinning. Background technique [0002] At present, most of the antistatic fibers are made of nylon or PET, which are modified by adding an antistatic agent and then spun.
