An environmentally friendly process has been achieved for the manufacturing of coated fabrics with the use of high solid reactive systems, which permitts the production of textile coating and expanded compact foils.
The physicomechanical tests show a significant possibility of improving the final product. If food approval was granted this process could replace the use of polyvinyl chloride (PVC).
The new system is being trialed at pilot plant level.
Potential applications of the polyurethane coated fabric include: covering for trucks, membranes, rubber boats, geotextile products, marine barriers, tents, etc.
A great deal of emphasis is being placed on developing polyurethane products that respond to customer's needs, while recognizing concern for the environment.
The covering material of technical textiles currently used for conveyor belts or for artificial leather is made by a spreading technique of PU dissolved in solvent.
The toxic solvent spread on fabrics creates air pollution and workshop contamination requiring costly environmental protection systems.
The development of a new process will be based on a new chemical formulation and technology avoiding the use of solvents.
The process will be environmentally friendly. The resulting processing system will be cost-performance quality competitive with present coating processes in artificial leather, in conveyor belts and in other technically coated textile applications.
After extensive tests on the prototype plants of two partners the technology and the production equipment will be specified in order to be suitable for S.M.E. workshops as well.
