| This process consists of lifting from the body of the
fabric a layer of fibres which stand out from the surface using card-wire.
Lubricants may be applied to the fabrics to facilitate the separation
of the fibres. |
After raising the pile is brushed and then cut using
rotating helical blades which act against a straight edge. The cropped
fleece may be treated with a hydrophobic finish e.g. fluorocarbon
to give enhanced water resistance in addition to the excellent insulating
properties of the fabric. |
