DOWN PROOF

Downproofness of Fabric


• Air Permeability Air permeability describes breathability

  of the fabric & may indicate downproofness.
• Downproofness Physical tumbling of the fabric filled with

  down/feathers determine downproofness.



  The next most common source of the leakage is through the  

  fabric itself. Heavy, coated fabrics are almost always very  

  down-proof whereas, very lightweight synthetic fabrics  

  and  damask & other patterned cotton fabrics allow more  

  material to pass through. 



• Downproofness (FSTM 191-5530 & EN 12132-1).

  This involves physically testing the fabric to simulate the

  use of the product.
