摘要： A woven tubular liner comprising an outer surface comprising outer wefts and warps and an inner surface comprising inner wefts and the warps, wherein the inner and outer surfaces are connected by the warps, the outer wefts being protected from an environment inside of the tubular linear and the inner wefts being protected from an environment outside of the tubular liner. The method comprises repeating a weaving unit of continuous outer wefts and continuous inner wefts running uninterrupted along a circumferential direction, woven with continuous warps running along a longitudinal direction, offsetting positions of the warps relative to the wefts in the weaving unit, selectively interlacing outer wefts with the warps, and selectively interlacing inner wefts with the warps.
