Quiz

With the quiz below you can test your knowledge on cleaner production in textile wet processing. After filling out the questions you can submit your answers to see how many of them are correct. 16 or more correct answers out of 20 makes you quite an expert. In case you have 15 or less correct answers, you are invited to take the test again. The test is purely for your own use and the results are not stored or otherwise used by the e-textile project team.
