聚酯薄膜以前被广泛用作研磨胶带的背衬材料。开发了一种新的研磨胶带，称为TETORON塔夫绸胶带。这种背衬材料由布料制成，比聚酯薄膜更柔软。本文介绍了用不锈钢管对传统研磨带和新型研磨带进行超精抛光的对比结果。泰托龙塔夫绸研磨带与工件的接触面积大于聚酯薄膜的接触面积。

POLYESTER FILM HAS PREVIOUSLY BEEN WIDELY USED AS BACKING MATERIAL OF LAPPING TAPE. A NEW LAPPING TAPE CALLED TETORON TAFFETA TAPE WAS DEVELOPED. THIS BACKING MATERIAL IS MADE OF CLOTH, THAT IS MORE FLEXIBLE THAN POLYESTER FILM. THIS PAPER PRESENTS THE RESULTS OF COMPARING POLISHING CHARACTERTISTICS FOR CONVENTIONAL LAPPING TAPE AND THE NEW ONE BY MEANS OF SUPERFINISH WITH STAINLESS STEEL PIPE. CONTACT AREAS BETWEEN TETORON TAFFETA LAPPING TAPE AND THE WORKPIECE ARE LARGER THAN THOSE OF POLYESTER FILM.
