Abstract

Abstract A novel antistatic agent soluble in organic solvent which can afford durable antistatic property to hydrophobic fibers and fibrous structures is provided. Such antistatic agent consists substantially of a complex compound of a polyvinyl derivative having quaternary ammonium groups in its side chains, its counter anion being substituted with an anionic surfactant containing 2 to 8 ethylene oxide units, an esterbonded sulfonate, an alkylamidocarboxylic acid salt or an amphoteric surfactant of carboxylic acid type. Hydrophobic fibers and fibrous structures having durable antistatic property, and a process for producing such hydrophobic fibers and fibrous structures also are provided, by utilizing the above antistatic agent.
