A preparation method of pearlescent pigment coating materials is provided. The method of the present invention lies in that titanium-iron ions in ilmenites are dissolved by using a hydrochloric acid at a certain temperature and pressure, and then ferrous chloride in the acidolysis solution is precipitated by adding hydrogen chloride gas, the remaining titanium-iron ions are separated from other colored ions by means of co-extraction using an extractant upon oxidation, and an enriched titanium oxydichloride solution and ferrous hydrous oxide are obtained by employing a fractional back extraction and enrichment method, the titanium oxydichloride solution can be used for mica-titanium based pearlescent pigment coating materials, and can also be used for preparing titanium dioxide; and the acidified ferrous hydrous oxide and the oxidized ferrous chloride can be used as iron based pearlescent pigment coating materials or used for preparing iron oxide pigments.

A process and composition is provided for preparing substrates with both visual and thermal camouflage. The substrate is metallized through a deposition process and polished or calendered to smooth the metal layer and lower the infrared emissivity of the layer deposited onto the substrate. The metallized substrate is then visually decorated by a tarnish and/or dying process that minimally impacts the infrared emissivity of the metallized substrate.

The present technology is directed to devices and methods for dyeing a fiber, including pretreatment of the fiber before contacting it with a dye. The present technology is also directed to methods of improving the dyeability of a fiber, as well as increasing the efficiency of the dyeing process and minimizing waste and loss of dye.

A phase-transfer catalytic color fixation processing method for textile includes the following steps: (1) dry-dyeing a textile with disperse reactive dyes in supercritical carbon dioxide fluid under waterless condition; (2) putting the textile in a phase-transfer catalytic fixation device, taking phase-transfer catalyst as the carrier of circulated supercritical carbon dioxide fluid, transporting the ionized fixing catalytic alkaline substance from aqueous phase to hydrophobic supercritical carbon dioxide fluid phase, getting full contact with functional groups on fibers, resulting in the fixing catalytic reaction with disperse reactive dyes.

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.
