How To Test Whether The Woven Bag Is Breathable?

Whether woven bag products are breathable is not only important for consumers, but also important for manufacturers of woven bags. But how to test whether woven bags are breathable? This is difficult for many enterprises or consumers to do quickly.

To test whether the woven bag is breathable, the woven bag processing factory shall analyze that: first, a tubular glass pressure gauge shall be placed at the bottom of the test box, or one side shall be vacuumized, and the gas will flow from the high pressure side of the thermal insulation material to the low pressure side. This pressurization method is generally used to measure the total differential pressure of the gas passing through the insulating material. The differential pressure of the gas passing through the sample will be clamped at the top of the test chamber, and the volume of the gas on one side of the sample will remain unchanged, because the differential pressure of the gas on both sides of the sample is equal to the total differential pressure.

In addition, whether the woven bag is breathable is also related to the final quotation of the product and the customer's choice, so it is necessary to test whether there is air leakage.
