    摘要： This invention relates to a lining material for the inner surface of a pipe of a pipeline used for transferring various fluids such as water supply and sewage, town gas, petroleum, and the like, and is characterized in that filaments having low elongation but high strength are used as yarns (12) for constituting a fibrous cylindrical member (13) together with a cylindrical woven fabric (2′) or as wefts (5), (16) constituting each cylindrical woven fabric (2), (6). Because of this feature, the lining material has excellent properties such as vibration-­proofness, shape retentivity against external pressure and small diameter expansion that are required for lining materials of pipeline.
    SUMMARY
    A lining material adapted for lining the inner surface of pipelines for transferring various kinds of fluids such as city water, sewage, city gases and petroleum, etc., characterized in that low elongation high tensile strength filament yarns are used as wefts (5), (16) forming tubular textile jackets (2), (6) laid in the lining material or as the yarns (12) forming a tubular fibrous member (13) together with a tubular textile jacket (2′). This characteristic feature provides excellent performances required for lining materials for pipelines such as enhanced earthquake resistance and shape retaining property against external pressures and limited expansion in diameter.
