The fashion tech department of Sona College of Technology has unveiled a ‘dynamic sweat transfer tester’ which tests a fabric’s ability to dry. The product can analyse the wicking behaviour of multi-structure fabric used for manufacturing sportswear and health care textiles.
The tester can be used at the fashion design and production stage. “Since it is part of the production process, it will not add any additional cost to the garment,” said D. Raja, Head of Department of Fashion Technology.
The working of the device is based on the absorbing behaviour of the fabric. And to have this trait, the fabric should draw off liquid through capillary action and should spread well so that the evaporation is quicker.
For the test, copper pins are used as a sensor and the sweat is injected through a syringe in the fabric. The sweat is spread in all directions and the time taken for the process is measured using the sensors that determine the fabric wicking behaviour.
The rate of sweat spreading to the fabric is measured on the principle of electrical conductivity.
Since the fitness and athleisure category has seen a surge in the demand due to pandemic, the device would provide a quick and easy method to check for the quality of the product that they are manufacturing.
