Selective partial coating of sheet materials, e.g. to make conductive patterns on textiles, involves applying a mask of intumescent material, coating the entire surface by thermal spraying and then removing the mask

摘要

A method for the selective partial coating of sheet materials by thermal spraying of coating material(s), involves applying a masking structure of intumescent material, carrying out at least one thermal spray procedure over the whole surface and then removing the masking structure. An independent claim is included for coated sheets in the form of knitted, woven or non-woven fabric, produced by the method described above.
