COOPERATION：
The aim of flock testing is to facilitate a reliable production process for flocking objects. Testing the properties of the material to be used, i.e. flock and adhesive, and also the properties of flock finished goods. Since 1975 different industry groups have developed approved testing methods and determined the testing procedures to be used. Practical testing methods were developed by exchanging information and experience between those companies involved.
