Abstract: Herein disclosed is a belt which is suitable especially for a sling to lift or hoist an article. The sling belt chiefly comprises a sheath of filament yarns made of polyamide synthetic fibers, and a core of filament yarns made of polyester synthetic fibers. The sheath covering the core has two sides, i.e., an upper or face side, which is to be brought into direct contact with the article, and a lower or back side which is apart from the article. The face side is made thicker than the back side to improve the anti-abrasiveness thereby to extend the life of the sling belt as a whole.
