TIRE CHAFER FABRIC is called breaker fabric .It’s a special industrial fabric mainly made of dipped Nylon 6, Nylon 66 and Polyester yarns. Chafer fabric is used for connect the shoulder and the rim of a tire.
A variety of materials are used as tire fabrics, including:
Bead Wrap: Tires use a loop of high strength wire cable that helps keep the tire mounted to the wheel, this wire bundle is often wrapped with a rubber coated nylon or polyester fabric called bead wrap. The fabric helps to prevent bead wire separation failure and is crucial to keeping the tire seated to the rim during operation and withstands the forces of the installation process. In addition, it offers an adhesive anchor point for the apex bead filler, sidewall and body plies that loop from bead to bead of the tire. For efficient tire production, it is crucial that the fabric has a well designed polymer system, including RFL and rubber coatings, to provide sufficient processing tack as well as adhesion to the various rubber stocks.
Chafer Fabric and Flipper Strips extend from the bead up the sidewall of the tire and are used to protect the tires. In addition, these fabrics provide abrasion resistance from the chafing effects of the rim and reduce damage to the carcass plies. Chafer fabrics are often woven polyester or Nylon 6,6 materials coated with an adhesive chemistry such as RFL.
