Abstract
The present invention concerns a method for manufacturing a woven informative support. The informative support (1) comprises a piece (2) of fabric, constituted by an interlacing of threads of at least two different colours. The interlacing of the threads of the piece (2) define the image (4) corresponding to an optically read code, on at least one face (3) thereof, through the contrast between at least two different colours.

1) A method for manufacturing a woven informative support provided with a QR code, comprising the following steps:
- choosing the height (Lt) of the QR code (5);
- choosing a total number of pixels (Px) per side of the QR code;
- choosing a loom with a certain number of warp threads per centimetre (Or/cm) ranging from 100 to 160;
- supplying a loom with a number of weft threads per centimetre (Tr/cm), in at least two colours, ranging from 60 to 120 per colour;
- interweaving, by means of said loom, of the weft threads and the warp threads, so as to obtain, by means of the contrast between the two colours of the weft threads, an image (4) that comprises the QR code;
- subjecting the informative support to a heating stage at a temperature ranging from 180° C. to 220° C.
