Liner for unvulcanized rubber member

摘要

A liner for an unvulcanized rubber member is provided that has excellent durability while maintaining the tackiness of an unvulcanized rubber member. An unvulcanized rubber member liner 10 is a plain fabric made from weft threads 14 of a split yarn of 1000 to 1330 dtex fiber diameter threads formed from a smooth faced resin film. Fine linear threads of multi-filament thread are employed as warp threads 12. Due to employing smooth surfaced split yarn weft threads 14, the surface of an unvulcanized rubber member 16 that makes contact with the weft threads 14 is also made smooth. The multi-filament threads of the warp threads 12 suppress the contact surface area with the unvulcanized rubber member 16 to a minimum. Accordingly the surface of the unvulcanized rubber member is made smoother overall than when a liner formed from a conventional plain fabric is employed. This results in excellent release properties while excellent tackiness of the unvulcanized rubber member can be maintained. A high durability is also obtained due to coating of the liner surface not being required.
