ABSTRACT:
A tubular lining material for pipe lines having a relatively large inner diameter and possibly a plurality of bends or curved portions, which comprises a tubular textile jacket made of warps and a weft knitted or woven in a tubular form overlaid with an air-impervious coating of a flexible synthetic resin and is applicable onto the inner surface of a pipe line which has a relatively large inner diameter and may have a plurality of bends or curved portions in such manner that the tubular lining material with a binder on the inner surface thereof may be inserted into the pipe line and allowed to advance within the pipe line with or without the aid of a leading rope-like elongated material while turning the tubular lining material inside out under fluid pressure thereby applying the tubular lining material onto the inner surface of the pipe line with the binder being interposed between the pipe line and the tubular lining material, characterized in that the warps are comprised of crimped yarns of polybutylene terephthalate fibers and the weft is comprised of a yarn of synthetic fibers. This tubular lining material is improved in biaxial stretchability, especially in lengthwise direction and has high flexibility and consistency so that the tubular lining material can be impregnated with a sufficient amount of a binder and applied onto the inner surface of the pipe line in good compliance with the shape of the inner surface without forming wrinkles or narrowing the flow path in bends or curved portions of the pipe line.
