Fabric

Abstract

A fabric has a unitary one-piece construction and includes a base layer and a first covering layer covering a first surface of the base layer. The base layer is formed by assembling at least a first yarn. The first covering layer is simultaneously formed with the base layer by assembling at least a second yarn when assembling the first yarn. The second yarn includes thermoplastic polymer.
