The Process
The powder is scattered onto/under a textile substrate which is transported via
two belts in between the two dielectric. The alternative high tension applied to
the electrodes creates ions which collide with the powder and charge
electrically the powder particles which are accelerated by the electric field.
The powder forms a cloud occupying all the space between the dielectric and
thanks to its kinetic energy, penetrates the fibrous substrate homogenously. Due
to a corona effect a modification of the fiber and powder surface may occur
improving further matrix adhesion. The process was developed in cooperation by
FIBROLINE SPRL and IFTH (Institute Français du Textile et de l’Habillement),
Lyon, France.
Advantages of Powder Impregnation
• Enables introduction of powders into already bonded products
• Requires no water
• Requires no solvent
• Obtains an intimate and homogenous mixture of fibers and matrix powder
• Applies to a very large variety of fibers and powders
• Environmental friendly and economic (low electricity consumption)
• Performance
• Reliability
• Fully automatic
