The invention relates to an improved method and apparatus for the treatment of animal skin substrates which employs a multiplicity of solid particles. There is disclosed an apparatus for treating one or more animal skin substrates with a multiplicity of solid particles and treatment liquor comprising: a rotatably mounted drum comprising an internal volume having a first portion defining a treatment volume for retaining said animal substrates and a second portion defining a collecting volume; one or more inlets for introducing solid particles and treatment liquor into said treatment volume; a partition separating said treatment volume from said collecting volume wherein said partition allows free passage of solid particles from the treatment volume to the collecting volume and prevents the passage of the substrates therethrough; a circulation path for conveying said solid particles from the collecting volume to the treatment volume; and a pumping device arranged to pump solid particles and said treatment liquor along a portion of said circulation path.

A method for providing visual effects to a decorative thread pattern, is provided. The method includes determining an object to be produced as such decorative thread pattern, determining a thread arrangement comprising a plurality of consecutive thread portions, each thread portion having a thread portion direction, wherein the entire thread arrangement corresponds to said object to be produced, determining at least one visual effect of said object to be produced, said visual effect being associated with a set of thread portions of said thread arrangement and having a direction being different from at least one thread portion direction of the set of thread portions, and determining a colouring scheme for a specific thread such that the visual effect is obtained when production of the decorative thread pattern, using said thread according to said thread arrangement, is performed. A control unit is also provided.

Provided is a sublimation transfer ink set including a yellow ink composition containing a yellow dye; a magenta ink composition containing a magenta dye; a cyan ink composition containing a cyan dye; a first black ink composition; and a second black ink composition, in which the first black ink composition contains the yellow dye and the magenta dye, and the cyan dye, and the second black ink composition contains a C.I. disperse blue 360.

A saturated extreme low liquor ratio conveyor-driving atmospheric fabric dyeing machine includes a machine body having an interior space having a rectangular lateral cross-section for effective use of the space and to accommodate an increased loading capacity of fabric. A conveyor device is installed inside the machine body to convey fabrics for circuiting movement. A dyeing tube is equipped above the machine body and is connected to the machine body at a front end and a rear end, at which a first nozzle and a second nozzle are respectively equipped to allow for selection between one single nozzle or two nozzles to jet dye liquid. A fabric plaiting down device and a fabric guide device are arranged at the rear end of the dyeing tube and in the interior space of the machine body and are adjustable for oscillation angle and amplitude in a left-right direction for optimization of oscillating and guiding the fabric to fall onto a conveyor device.

A dye discharge composition exhibiting extended shelf life and/or pot life and high suitability for inkjet printing on dyed substrates, is disclosed. The composition comprises a reducing agent such as, for example, a sulfur-based reducing agent, and a chelating agent, such as a sodium salt of a polyamino carboxylic acid chelating agent. Use of the dye discharge composition in combination with a translucent colored composition and an optional opaque underbase composition, for forming an image on a dyed substrate is also disclosed. Processes for inkjet printing of an image on a dyed surface using the dye discharge composition, kits for use in such processes or an ink formulation containing same are also disclosed.

The present invention relates to a process for dyeing textiles, in particular for dyeing textiles using enzymes. The present invention also relates to a method for producing leuco indigo and/or leuco forms of indigo derivatives. The present invention further refers to textiles obtainable through said process, to an apparatus comprising a reactor containing enzymes, and to a microbial flavin-containing monooxygenase.

Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image.

Silkworm silk, has been processed into a variety of new material formats including, hydrogels, ultrathin films, thick films, conformal coatings, 3D porous or solid matrices, fibers and many related material formats. Silk is processed in an all water-based, room temperature, neutral pH environment, is mechanically stable, edible, and biocompatible. Given the favorable material properties, the use of silk-based inks have been used in a variety of controlled chemical and biological material fabrication on the micro- and nano-scale. Tuning of the properties of silk-based inks has led to the utilization of more diverse printing techniques and has expanded the scale and function of the printed substrates.

Methods for coloration of substrates, including textiles, by plasma polymerization of dyes to which polymerizable moieties have been chemically bonded at sites on the dye capable of bonding to such moieties, and that have been deposited on at least one surface of the substrate, are described. Atmospheric pressure plasmas were used for the polymerization process. Generally, the plasma polymerization is performed away from the dye deposition so that undeposited dye is not exposed to the plasma. Textiles may include cotton, polyester, wool, silk, acrylics, polypropylene, polyolefins, aramids, and nylon, and blends thereof. The plasma-polymerizable moiety may be chosen from acrylates, methacrylates, and vinyl amides. Dye functional groups may include hydroxyl groups, carboxyl groups, amines: primary, secondary, and tertiary, epoxides, carboxylic acids, and chlorides, and dyes may include acid dyes, disperse dyes, azo dyes, vat dyes, sulfur dyes, direct dyes, reactive dyes, basic dyes, pigment dyes, aniline dyes, anthraquinone dyes, and coumarin dyes, as examples.
