The leather breathability tester is a testing equipment independently developed and produced by our company Qisnun Precision Electromechanical Technology Co., Ltd. It is cost-effective and has comprehensive after-sales service. It is used for automotive interior materials, such as polyurethane foam, PVC, leather and textiles. , non-woven fabrics and other materials air permeability and air resistance testing, through measurements, to meet the requirements for controlling the physical properties of materials to meet the needs of practical application of products. In addition, it can also be used to test the air permeability of separation membranes, sponges, carpets, non-wovens, paper and leather.

Applicable standards:

Main parameters:

1. Measuring range: 0~2400ml/(c㎡.h)

2. Test duration: 15 seconds on average

3. Test area: 10c㎡

4. Sample diameter: 5cm

5. Pressure range: 10Pa~2500Pa

TestingPrinciple of adjustment:

Method A

Stabilize the air flow passing vertically through the sample at a constant rate and measure the test flow rate under these conditions . The pressure difference formed on both sides of the sample is used to calculate air flow resistance and other parameters.

Method B

By adjusting to form a constant pressure difference on both sides of the sample, measure the flow of air passing vertically through a given area of ​​the sample in a certain period of time and calculate parameters such as air permeability.

Testing process:

(1) Cut 3 specimens with a diameter of 5 cm from the leather sample to be tested.

(2) Take a sample and fix it in the equipment. The equipment connects to the air source, adjusts the valve de pressure regulation and adjusts the pressure difference on both sides of the sample. When the pressure difference on both sides of the sample reaches the set value, the equipment automatically measures and records the air flow entering the sample.

(3) Repeat the sample loading and adjust the pressure operation until all three samples have been tested.

Shanghai Fanbiao Textile Testing Technology Co., Ltd., as an enterprise integrating R&D, manufacturing, sales, training and service, is committed to putting more testing instruments to the market and provide long-term textiles, leather, combustion testing instruments, automobile interior materials, environmental climate aging, masks and protective clothing, etc. can also be customized to meet non-standard requirements. Targeted tests can be carried out in fanointing customer requirements before purchase to ensure that the instruments purchased are suitable.
