Abstract
A yarn spun from a plurality of nano-fibers is provided and is characterized in that at least some of the nano-fibers are folded with the folds occurring at predeterminable distances which are integer multiples of a specific spacing. The folds result from spinning the nano-fibers onto a plurality of moving conductive strips which are inclined to their direction of movement. A process and apparatus for producing such yarn is also provided.

A yarn spun from a plurality of nano-fibres, consisting essentially of nano-fibres that are folded with the folds occurring at predeterminable distances.
A process for producing a yarn which includes electrostatically spinning a plurality of fibres onto a plurality of moving conductive strips inclined to their direction of movement such that the fibres span at least some of the conductive strips, collecting the fibres from the conductive strips to form a web of fibres, and forming the web of fibres into a yarn.
A process for producing a yarn, comprising:
- electrostatically spinning a plurality of fibres onto a plurality of moving conductive strips inclined to their direction of movement such that the fibres span at least some of the conductive strips, wherein the conductive strips have a uniform thickness of between 100 nm and 30 mm;
- collecting the fibres from the conductive strips;
- and
- forming the fibres into a yarn.
An apparatus for producing a yarn including an electrostatic spinning source and a plurality of conductive strips arranged to collect fibres from the spinning source and movable with respect thereto and a web collector and a web twister arranged in series therewith, wherein the conductive strips are inclined to their direction of movement.
An apparatus for producing a yarn, comprising:
- an electrostatic spinning source;
- and
- a plurality of conductive strips arranged to collect fibres from the spinning source and movable with respect thereto and a web collector and a web twister arranged in series therewith, wherein the conductive strips are inclined to their direction of movement, wherein the conductive strips are equally spaced apart, and wherein a spacing between conductive strips is between 1 μm and 300 mm.
An apparatus for producing a yarn, comprising:
- an electrostatic spinning source;
- and
- a plurality of conductive strips arranged to collect fibres from the spinning source and movable with respect thereto and a web collector and a web twister arranged in series therewith, wherein in that the conductive strips are inclined to their direction of movement, and wherein the conductive strips have a thickness between 100 nm and 30 mm.
