An article of manufacture, comprising, an artifact formed from at least a portion of at least one continuous artifact fiber, the artifact fiber dyed by a first digitally controlled dyeing process to exhibit a visible first color section and a visible color gradient section transitioning from and visibly distinguishable from the first color section; and, a textile portion, comprising at least one dyed fiber that has been dyed by a second digitally controlled dyeing process; wherein said artifact fiber is dyed by the first dyeing process applying metadata, said metadata relating to at least said first color, and wherein said textile portion fiber is dyed at least said first color by the second dyeing process applying said metadata.

An authentication device comprising a woven authentication pattern, wherein the woven authentication pattern comprises a plurality of pattern forming woven elements each defining at least one pattern defining element or a plurality of pattern defining elements, and each pattern forming woven element is formed by a plurality of threads having contrasting optical or visual properties in twisted mutual engagement, wherein said pattern defining element has a spiralling outline or boundary and adjacent or abutting pattern defining elements of a pattern forming woven element are visually or optically distinguishable.

The invention provides a light-reflective mark formed with light-reflective yarn. The light-reflective mark is made on a sheet material, the sheet material is an article that can be sewn or embroidered or a knitted fabric; the light-reflective mark is a pattern formed with graphics and/or texts, and is formed by combining one or more than one light-reflective yarns with the sheet material by sewing, embroidery or weaving. Thereby, daily supplies or clothing can be provided with the light-reflective mark of the invention, so as to improve the safety of daily activities. The light-reflective mark can be made into an aesthetic pattern, or a pattern or a text with a specific shape, such as graphic or text of a logo, so that the article or clothing with the light-reflective mark is fashionably and aesthetically pleasing.

The invention relates to an adhesive tape, in particular winding tape for bandaging elongated objects, such as cable bundles in automobiles for example. The adhesive tape has a fabric support (1, 2), additionally an adhesive coating (3) which is applied onto one side or both sides of the fabric support (1, 2), and at least one marking thread (4, 5) which is introduced into the fabric support. According to the invention, the marking thread (4, 5) is a warp and/or weft thread (4, 5) which is incorporated into the fabric support (1, 2) during the production process.

An authentication device comprising a woven authentication pattern, wherein the woven authentication pattern comprises a plurality of pattern forming woven elements each defining at least one pattern defining element or a plurality of pattern defining elements, and each pattern forming woven element is formed by a plurality of threads having contrasting optical or visual properties in twisted mutual engagement, wherein said pattern defining element has a spiralling outline or boundary and adjacent or abutting pattern defining elements of a pattern forming woven element are visually or optically distinguishable.

An article includes an identifier fiber. The identifier fiber includes a photonic structure that, upon illumination, produces an optical response having an optical parameter value. The optical parameter value, at least in part, identifies a particular article characteristic. The inclusion of the identifier fiber in the article indicates, at least in part, that the article has the particular article characteristic.
