Abstract

PURPOSE: To obtain the subject spun yarn having a specific strength and a boiling water shrinkage, excellent thermal properties, becoming stronger by a heat-treatment and useful as a sewing yarn for a protective wear, protective gloves, a leather, etc., comprising wholly aromatic polyester fibers having a specific fiber length. CONSTITUTION: This spun yarn is composed of wholly aromatic polyester fibers having 70-300 mm average fiber length (preferably a polyester comprising p- hydroxybenzoate with 6-hydroxy-2-naphthoic acid), >=3 g/d strength and <=2% boiling water shrinkage.
