Dryer fabric contaminants come primarily from the furnish and its additives and from coating or size press chemicals. Cleaning should proceed only after identifying the type and degree of contamination of your particular fabric.

Tests have shown that even a small amount of contamination can cause pronounced reduction in dryer fabric permeability. Pronounced contamination is common after size presses and coating positions. In these cases, it is not unusual for dryer fabric to be completely plugged.

Dryer fabric contaminants divide into four groups:
1.  Dust
   -short cellulose fibers
2.  Cross-linked organic substances
   -Wet strength resins.
   -Latex based coating chemicals (SBR, acrylic, and others).

3.  Organic substances not cross-linked
   -Pitch.
   -Asphalt, tar, wax (often from recycled furnish).
   -Size from CMD size press, starch and casein types.
   -Bearing oil and grease.
4.  Non-organic substances
   -Alum, calcium carbonate, kaolin, titanium dioxide, rust and scale.
