Fibre disentangler

Sliver cuts are first made to each individual fibre

Copper helix pipes

Copper is an appropriate choice of material in the triboelectric series with good grounding properties.

When fibres rub against copper pipes, protein fibres are positively charged while synthetic fibres are negatively charged.

Electrodes

Two high potential plate electrodes of opposing polarity are used to attract the 2 types of fibres, thus fibre separation.
