<P>PROBLEM TO BE SOLVED: To provide a drawing resistant liner for lining a pipe, the pipe lined by the drawing resistant liner, and a method of lining the pipe by the drawing resistant liner. <P>SOLUTION: This liner 10 is made of a laminate including a sealing later 12, a strength layer 14 comprising a drawing resistant woven material for coating the sealing later 12, a support layer 16 for coating the strength layer 14 of a nonwoven cloth impregnated with a resin, and a barrier layer 18 for coating the support layer 16. The laminate is rounded into the pipe, and is reversed, when inserted into the pipe, to make the barrier layer 18 serve as a layer adjacent to an inner wall of the pipe, to make the support layer 16 serve as an under layer of the barrier layer 18, to make the strength layer 14 serve as an under layer of the support layer 16, to make sealing layer 12 serve as an under layer of the strength layer 14, and to make the strength layer 14 contact with a material flowing through the pipe. <P>COPYRIGHT: (C)2011,JPO&INPIT |
