Key Leather Quality Indicator - Leather's Breath - Air Permeability Testing Explained-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Key Leather Quality Indicator - Leather's Breath - Air Permeability Testing Explained The tiny spaces between leather's collagen fibers act like vents for air and heat. Throughout the leather processing stages (acid-alkali treatment, stretching, rubbing, fat liquoring, tanning, and finishing), the size, uniformity, and quantity of these spaces are affected. This directly impacts the leather's breathability. Here's where the air permeability test comes in. This specific test focuses on leather used for garments. The testing method adheres to the standard QB/T 2799-2006, which utilizes the differential pressure method to assess air permeability. The instrument used in this test is the TQD-G1A Air Permeability Tester, designed by Labthink Instruments Co., Ltd. This instrument boasts two test modes with varying control factors, fixed pressure difference and fixed air flow rate mode, it can assess car interior materials (polyurethane, PVC, textiles, nonwovens), textiles (cloth, nonwovens), porous polymer materials (sponges), paper materials (tissue, toilet paper).

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 The result showed average air permeability of the tested leather sample was 115 mL/(cm²h), calculated from three test results with a specimen area of · 8.04 cm² . Air permeability is a crucial factor in determining leather quality. Leather breathability, specifically how air permeability affects the comfort and quality of leather products, particularly garments and shoes. The study highlights the importance of air allowing sweat and heat to escape, preventing that unpleasant feeling of being hot and damp. More gas transmission...
