Kit Comparison
Method:• Three drops of the IPA/Water
solutions are placed on the fabric• Fabric passes the test if no wetting
is observed after ~15 seconds

Stain Release
Concept: Test measures ability of fabric to release oily stains during home laundering.
Method:Corn oil and mineral oil applied to fabric.Glassine surface placed on top followed by a 2.27 kg weight for 60 seconds.Surface and weight are removed and the fabric is washed.
Stain Release Test AATCC 130

Wash Durability
• Allows fabric to be washed/dried as much as required
• Sample evaluation is completed again after the wash/dry cycles are completed
• Provides a numerical value for performance longevity
• Used in stain release evaluations

Hydrostatic Pressure Testing
• Equipment measures the force (kPa) and time required to force a liquid, usually water, through a piece of fabric.
• The larger the force and time required to penetrate the fabric the more resistant the fabric is to that particular liquid.
• This equipment provides a means of quantitatively differentiating treatments that perform similarly in the testing discussed earlier.

Static Decay Testing
• Static Decay measures the time it takes for the charge applied to fabric to dissipate
• Decay data is useful for medical garment and carpet customers

Surface Resistivity
• Electrical resistance of the fabric surface is measured between two concentric rings.
• Comparing the voltage gradient to the current density provides a numerical value of how much charge can build up on the surface of the fabric.
