Abstract
The present invention is generally directed to a release liner adapted to separate adjacent layers of an elastomeric material. The release liner, which can be a woven fabric, is made, at least in part, from a fibrillated yarn. The fibrillated yarn provides a more textured surface to the release liner than a multifilament yarn of the same material, which allows the release liner to be easily separable from the elastomeric material. The release liner made according to the present invention is durable and can be used repeatedly before being replaced.
Claims23
A layered elastomeric article comprising:
- a plurality of layers of a sheet-like elastomeric material;
- and
- a release liner placed between adjacent layers of said elastomeric material for preventing said layers of said elastomeric material from sticking together, said release liner comprising a fabric made from at least one type of yarn, said at least one type of yarn comprising a fibrillated yarn.
A release liner comprising:
- a woven fabric adapted to be placed between adjacent layers of an elastomeric material for preventing said layers of elastomeric material from sticking together, said woven fabric including a warp yarn and a fill yarn, said warp yarn comprising a fibrillated yarn having a denier from about 500 to about 700.
A release liner comprising:
- a woven fabric adapted to be placed between adjacent layers of an elastomeric material for preventing said layers of elastomeric material from sticking together, said woven fabric including a warp yarn and a fill yarn, said warp yarn comprising a fibrillated yarn made from a network of interconnected and discontinuous fibrillated filaments, said fibrillated yarn having a denier from about 500 to about 700, said fill yarn comprising a monofilament yarn having a denier from about 300 to about 500, said woven fabric having from about 35 warp yarns per inch to about 45 warp yarns per inch and from about 30 fill yarns per inch to about 40 fill yarns per inch.
A method of separating multiple layers of an elastomeric material, said method comprising the step of:
- providing a plurality of layers of sheet-like elastomeric material;
- and
- placing a release liner between adjacent layers of said elastomeric material, said release liner comprising a fabric made from at least one type of yarn, said at least one type of yarn comprising a fibrillated yarn.
