Other tests.

Together with the shrinking test we also did a lot of other tests, especially in conjunction to colour fastness. We tested the colour fastness of our products in relation to perspiration, water, washing and rubbing. While testing our products in relation to perspiration and water, we soaked our products together with a multifibre material in an acid and an alkaline perspiration solution in 30 minutes before we put every sample for a drying cupboard at 37 degrees in four hours.

While we were waiting for the perspiration test to be finished, we started the washing test. Each sample together with a multifibre material had its own small container because they were not supposed to colour each other during the wash. Together with our products and the multifibre materials we put some very small and heavy metal spheres and soap.

The last test we did on colour fastness of our products before taking out the perspiration test from the drying cupboard was the rubbing test. Would our products/Maria's clothes lose colour due to rubbing (both wet and dry)? This was to be done by a rubbing machine. 

Of course after one day with different kinds of testing, you also need results. We used the grey scales to compared the tested materials to materials that had not been tested. The grey scales are able to tell us if the colour staining and colour change are good or bad, where five on the scale is very good.
