Problems solved by technology

However, during lamination and coating of fluororesin, the fluororesin film is thin and non-adhesive, so it is easy to peel off, and in order to maintain sliding properties for a long time, it is necessary to repeat lamination and coating

Abstract

To provide a sliding fabric having excellent sliding properties and durability, in which the amount of compression in the thickness direction when a load is applied is low, and play does not occur between members. A sliding fabric in which, on at least one surface of the fabric, fluororesin fibers (X) and other fibers (Y) are alternately disposed as the warp and / or the woof, and the compression distance of the fabric is 25 [mu]m or less.

Description

technical field [0001] The present invention relates to a sliding fabric containing fluororesin fibers suitable as a sliding material. Background technique [0002] Conventionally, fluororesins have been used by laminating and coating on the surface of sliding members, taking advantage of their low coefficient of friction. However, during lamination and coating of fluororesin, the fluororesin film is thin and non-adhesive, so it is easy to peel off, and it is necessary to repeat lamination and coating in order to maintain slipperiness over a long period of time. In order to eliminate such shortcomings, it has been developed to fiberize fluororesin, make woven knitted fabrics and non-woven fabrics, and arrange them on the surface of sliding members to improve friction durability, or further combine them with woven fabrics that are easy to bond with other raw materials. Sliding materials that are bonded more firmly by compounding knitted fabrics. [0003] For example, Patent...
