Latest Patents

Piermattei holds a patent for a laminate material that features a microfibrous polyurethanic base sheet. This imitation leather laminate material consists of a base sheet made up of 50 to 90% by weight of microfiber felt. The microfibers used are either polyethylene terephthalate, polyamide 6, or polyamide 6-6, with a denier ranging from 0.05 to 0.4. The remaining 50 to 10% by weight comprises a polyurethane-polyurea polymer, which has an average molecular weight that corresponds to a polymer solution viscosity between 10,000 to 50,000 centipoise when the solution is 25% by weight in dimethylformamide at a temperature of 20°C. The resulting base sheet has a final weight between 140 to 450 g/m² and a density ranging from 0.20 to 0.40 g/cm³, and it is backed with one or more functional substrates adhered to it.
