The present invention is a process for converting a multilayer filament to a plurality of nano-ribbons. The process includes co-extruding a first layer and a second layer to form the multilayer filament, and separating the multilayer filaments to form a plurality of nano-ribbons having substantially flat cross-sections.

A process and a splitter for splitting a tape of a uniaxially oriented material. The tape is passed in a process direction over a static splitting profile having a row of teeth, e.g., with a cutting edge extending in the process direction. The tape is split to form a material comprising a plurality of parallel strips interconnected by fibrils. The split material can for example be used for the production of high tensile ropes or laminates.

Woven irrigation tubing comprising a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.
