The Importance of Fabric Air Permeability

2023-04-01 00:47:04

The air permeability of fabrics can have a major impact on people's lives.

Fabric Air Permeability

Air permeable fabrics allow air to pass through them, which helps regulate body temperature and keep people comfortable. The breathability of fabrics is especially important in hot climates, as breathable fabrics help people stay cool and dry. In colder climates, air permeable fabrics help trap heat closer to the body, keeping people warm. In addition, air permeable fabrics are also beneficial for allergy or asthma sufferers, as they allow air to circulate more freely and reduce the risk of dust and other allergens accumulating in the fabric. Breathable fabrics can help reduce energy costs through natural ventilation rather than relying on mechanical systems like air conditioning or heating.


So how to measure the air permeability of clothing fabrics?

1. Cut two pieces of fabric to be tested into squares of equal size.

2. Place one piece of fabric over the frame with the hole in the middle and the other piece of fabric directly under the frame.

3. Use an air permeability tester to simulate blowing air through the holes in the frame and use an anemometer to measure the amount of air passing through both pieces of fabric.

4. Compare the readings of the two fabrics and calculate the air permeability by subtracting the reading of one from the reading of the other. The greater the difference, the better the breathability of the fabric.
