double winder line
Our 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
