This invention relates to a process and apparatus for dyeing of textiles, to an immobilized enzyme comprised in said apparatus required for carrying out the process, and to a method to produce enzymatically indigo and derivatives thereof.

Impact indicator compositions, application devices, and methods comprising coating a surface to be impacted, wherein the coating comprises microcapsules having a cross-linked polyurea shell and a core surrounded by the shell, the core comprising at least one color former; and a developer capable of activating the color former when in contact therewith.

The invention describes a color-developing composition that contains at least four major components: (1) a leuco dye or a combination of leuco dyes, (2) an electron-withdrawing color-developer agent or a combination of color-developers that can form colored complexes with the leuco dyes, (3) a separator or combination of separators that when present in sufficient amounts, can prevent the formation of the colored complexes between the color-developer and leuco dyes, all contained within (4) an encapsulation matrix that includes at least one film-forming and one aqueous-insoluble polymer. All of the foregoing components are dissolved together in a volatile organic solvent medium to form a homogeneous solution that can be applied as an ink on substrates, which can be incorporated as part of absorbent articles or personal care products.

The invention relates to a colorant composition for coloring fibers and fabrics comprising leucoindigo and at least one organic solvent. To achieve a stable composition, which is broadly applicable to different fibers and fabrics, the water content of the composition is less or equal to 10 wt.-% of the total weight of the composition or the water content of the composition is less or equal to 60 wt.-% of the total weight of the composition and the composition also includes a base.

The present invention relates to a process wherein one or more dye precursors, e.g., indole, are provided to a textile and converted by one or more enzymes, e.g., an oxidizing enzyme, to provide the textile with a dye, e.g. indigo. At least the oxidizing enzyme is a hybrid enzyme including a binding domain that is suitable to bind the enzyme to the textile and/or increase the affinity of the enzyme for the textile, in particular, a cellulose binding domain (CBD).
