METHOD FOR PREPARING ELECTRICALLY CONDUCTIVE POLYAMIDE- POLYOLEFIN COMPOSITE FIBER AND ELECTRICALLY CONDUCTIVE COMPOSITE FIBER PREPARED THEREBY

摘要

The present invention relates to a method for preparing an electromagnetic wave shielding polyamide-polyolefin composite fiber with an improved electromagnetic wave shielding performance. According to the method, an electromagnetic shielding component of a composition obtained by dispersing carbon nanotube in polyamide polymers using a conductive agent become an interlining component and a polyolefin containing a low-melting point metal element becomes a core component and the interlining component and the core component are compositively spun. According to the present invention, the electromagnetic wave shielding hollow fiber with improved durability and electromagnetic wave shielding performance can be prepared through a simple process.
