Beschreibung
Zusammenfassung:	A seamless tubular liner for repairing an underground or surface pipe is disclosed, including circumferential wefts consisting of slivers comprising a plurality of staple fibers bundled together, the slivers adapted to elongate through disentanglement of the bundled staple fibers when the seamless tubular liner is subjected to an inflation pressure such that the diameter of the tubular liner is able to expand to accommodate variations of diameter of the pipe being repaired. Un revêtement tubulaire sans soudure est décrit pour réparer un tuyau sous-terrain ou de surface. Le revêtement comprend des trames circonférentielles, qui consistent en rubans composés de plusieurs fibres discontinues regroupées, les rubans étant adaptés pour sallonger par démêlement des fibres discontinues regroupées lorsque le revêtement tubulaire sans soudure est soumis à une pression de gonflage, de sorte que le diamètre du revêtement tubulaire soit capable de gonfler pour sadapter aux variations de diamètre du tuyau étant réparé.
