Fiber collectors

Nanofiber yarn collector

Spiral collection for nanofiber yarns and three-dimensional fiber mats. Prepare yarn with or without a core, or build up layers of fibers into a thicker mat.

Nanofiber yarn, with or without a core

Nanofiber collection using core-yarn traction

Collection with a core yarn

A core yarn provides traction during collection. Nanofibers gathered at the spiral collector are drawn together with the core yarn to form a continuous yarn.

Coreless yarn formation at the spiral collector

Collection without a core yarn

Nanofiber yarn can also be collected without a core yarn. The photographs show the fiber bundle forming at the collector and the yarn being drawn away for take-up.

From collected fibers to yarn

The collection arrangement brings deposited fibers together into a yarn. This view shows the collector and yarn path during operation.

A closer look at the collected yarn

Scanning electron microscope images show the yarn and its surface at different magnifications. Enlarge each image to inspect the fibers and the original scale bar.

Build up three-dimensional fiber mats

Fiber deposition for three-dimensional mat preparation

The spiral collector can also be used to prepare three-dimensional fiber mats. Continued fiber deposition builds up successive layers, increasing the thickness of the collected mat.

Collected mats and layered structure

The sample photographs show the collected mat from above and at the lifted edge, revealing the accumulated fiber layers.
