Abstract:
A method for making an elastic fabric for a damper or cone edge, comprising extracting an elastic thread from a combination of spandex, and at least one fiber composed of cotton, polyester and aramid, andweaving the elastic thread to the elastic fabric, wherein the spandex has a volume from 0.1 to 5.0% of the total volume of the elastic fabric and the cotton, the polyester and the aramid has a volume from 99.9 to 95.0% of the total volume of the elastic fabric, wherein the spandex has a forming temperature of 150Â° C.Â±10Â° C., the cotton has a forming temperature of 245Â° C.Â±20Â° C. the polyester has a forming temperature of 200Â° C.Â±20Â° C. the aramid has a forming temperature of 235Â° C.Â±10Â° C., whereby the elastic fabric has a forming temperature of 175 to 250Â° C., which is higher than the forming temperature of the spandex but lower than any of the remainder of the combination.
