It’s a lightweight and loosely fabric made of cotton fibers. Created in 1888 by Lewis Haslam and a couple of doctors, who were his partners.
The discovery of the fabric was a result of experiments with air. After some time researching they were able to create a type of fabric that could maintain the warmth of the body and block the cold from outside without loosing it’s lightweight characteristic
With the result of the research Lewis and his partners were able to open the Aertex company.
In 1891 the Aertex fabric was already commonly used by the British middle class. During the WWII part of the British army started using aertex uniformes. In 1959, together with the company Ovoltine, the Aertex company sponsored the the ‘All New Netball Associations’ coaching film. In 1960 the Aertex fabric was used to manufacture school and sports uniforms in United Kingdom. The English football squad used Artex fabric jerseys made by Umbro company during the 1970 World Cup, in Mexico.
The fabric remains very much in use today.
