Abstract
An irrigation pipe formed from a sheet that is rolled into a tube about a longitudinal axis of the sheet. The pipe has a watertight layer and a fabric layer. The fabric layer comprises a first fiber arrangement including first main fibers having a first orientation and a second fiber arrangement including second main fibers having a second orientation. The first and second orientations are transverse relative to each other and to the longitudinal axis when viewed in the sheet before it is rolled.

An irrigation pipe formed from a sheet that is rolled into a tube about a longitudinal axis of the sheet, the sheet comprising a watertight layer and a fabric layer, the fabric layer comprising a first fiber arrangement including first main fibers having a first orientation and a second fiber arrangement including second main fibers having a second orientation, wherein the first and second orientations are transverse relative to each other and to the longitudinal axis when viewed in the sheet before it is rolled wherein:
- the fabric layer comprises a first fabric sub-layer and a second fabric sub-layer, the first fabric sub-layer comprises the first fiber arrangement and the second fabric sub-layer comprises the second fiber arrangement;
- and
- the first fabric sub-layer comprises auxiliary fibers extending along the longitudinal axis and the second fabric sub-layer comprises auxiliary fibers extending along the longitudinal axis.
An irrigation pipe formed from a sheet that is rolled into a tube about a longitudinal axis of the sheet, the sheet comprising a watertight layer and a fabric layer, the fabric layer comprising a first fabric sub-layer and a second fabric sub-layer attached to each other, the first fabric sub-layer having a first fiber arrangement comprising first main fibers having a first orientation, the second fabric sub-layer having a second fiber arrangement comprising second main fibers having a second orientation, the first and second orientations being transverse relative to each other and to the longitudinal axis when viewed in the sheet before it is rolled.
An irrigation pipe comprising a water tight inner layer, an outer layer and a fabric layer therebetween, the outer layer being formed with gaps that permit passage of fluid therethrough from the fabric layer.
