Polyurethane or synthetic leather

TECHNOCEL® provides capillaries in the production process

Polyurethanes are the most important polymers for the production of micro-porous synthetic leather.

In the most important production method, the coagulation process, polyurethane is solved in dimethylformamide and mixed with technical cellulose fibre. The mixture is brushed onto a textile carrier and submersed in a water bath. Then, dimethylformamide is replaced by water. The end product is synthetic leather.

The fibres provide capillaries in the production process. In the finished end product, TECHNOCEL® cellulose fibres improve steam permeability or breathability as well as mechanical stability.
