High quality natural fibres made from textile cotton cloths are used as the raw material of our DYNOS® and DYNAL® quality products. As a result of their rigid nature, those cotton rags are among the prime semi-finished products within the paper industry. They are also used for the production of durable and rigid papers – such as bank notes or document paper.
First the rag fibres are broken up, sorted and subjected to an extensive regeneration process. By cooking in pressure vessels and subsequent grinding the cotton rags gain high reactivity for the parchmentisation to Vulcanized Fibre. The resulting pulp is then being processed on paper machine accordingly.
