Double winder line: DWL

The Xplore double winder line (DWL) is specially designed to be used to wind, elongate and de-wind polymer fibres. It enables you to pass a fibre through a temperature-controlled oven for heat treatment or a bath of liquid with additives to impregnate the fibre(s), as a result altering the properties of the mono or multifilament fibre.

‍

The DWL can also be utilized as a winding and de-winding instrument for testing the optimum wind and de-wind conditions for (brittle) fibres e.g lignin to enhance and or speed up fiber R&D (e.g lignin to C-fiber R&D). The DWL is designed to enable an experienced process engineer to wind and de-wind a very fragile mono-filament or multi-filament in between a carbonisation oven to treat e.g a lignin mono-filament into a C-fiber (this particular oven is not included). Or to guide the multi or mono-filament fibre through a liquid or solvent bath. The winding, de-winding speed and elongation ratio of the DWL are adjustable, allowing it to be precisely tailored to each fibre heating or coating application.

Key features

• Smaller samples, faster sample generation. Only a fraction of material and time is used compared to the conventional altering of fibre properties.
• Able to be used with mono and multifilament fibres
• Very slow draw and stretching rates possible
• Can be retrofitted with an existing oven or liquid bath
• Variable settings; winding speed, draw ratio and overlap pitch can be adjusted to influence or alter the properties of fibres
• Large operating window
