LR-Q052 Leather Air Permeability Tester Air Permeability Meter Fineness Apparatus
Leather can be characterized by its property of allowing air to pass through, which is known as breathability (or permeability). Breathability is one of the valuable properties of leather, and it, along with the water vapor permeability, is an important indicator of the hygiene performance of the leather, directly affecting the comfort during wearing.
Standards:
GB/T 4689.22-1996 Leather - Method for Measuring Air Permeability, QB/T 2799-2006 Leather - Method for Measuring Air Permeability.
