The present invention refers to a plant (1) for printing a fibrous material (T). The printing plant (1) comprises: a station (14) for supplying a fibrous material configured for supplying the fibrous material along a predetermined operative path, a treating station (10) configured for treating the fibrous material with a treatment composition by applying the composition itself on a first side (T1) of the fibrous material (T) ; and a printing station (6) configured for ink-printing at least part of a second side (T2) of the fibrous material (T) opposite to the first side (T1). Moreover, the present invention refers to a process of printing a fibrous material.

Processes are disclosed which substantially eliminate the formation of oxidized indigo dye before and during dye application onto a natural fiber yarn or fabric while allowing the leuco-indigo dye molecule to diffuse fully into the natural fibers of the yarn where it can fix to the fibers prior to oxidation (i.e., exposure of the leuco-dyed yarns to oxygen). Indigo dyed textile products (e.g., dyed cotton yarns that may be twill woven to form a denim fabric) exhibit exceptionally high colorfastness as determined by the AATCC Crock Test.

A composition comprising: (i) an electrically non-conductive fiber having a surface; and (ii) piezoelectric particles adhered to the surface of said electrically non-conductive fiber, and optionally, (iii) a sizing agent (e.g., epoxy) coated over the piezoelectric particles and surface of the electrically non-conductive fiber. Also described are composites in which the above fiber composition is embedded within a matrix, e.g., a polymer, ceramic, or glassy carbon matrix. Also described is a method for producing a passive sensing fiber composition by: coating a fiber having a surface with a liquid suspension containing piezoelectric particles suspended in a solvent; and removing the solvent to result in the piezoelectric particles adhered to the surface of the fiber. Also described are methods for detecting formation of defects in a material and methods of generating electrical energy from ambient vibration by use of the above described fiber compositions and composites thereof.
