The present invention provides water-based ink and coating compositions comprising greater than 70 wt % natural materials. The ink and coating compositions of the present invention are suitable for printing on feminine care products, baby care products, and other personal care products.

A method for producing a printed textile item is disclosed, the method including applying a pretreatment liquid containing a coagulant, water and a surfactant to a fabric, and, after the application of the pretreatment liquid, applying a white ink containing a white pigment and water to the fabric by an inkjet method, wherein a surface tension of the white ink at 0.05 Hz is within a range from 33 to 39 mN/m, a surface tension of the white ink at 10 Hz is 40 mN/m or greater, a specific gravity of the pretreatment liquid is greater than a specific gravity of the white ink, and the application of the white ink is performed within 100 seconds from the application of the pretreatment liquid and by a wet-on-wet method.

An example fixer composition includes a glycidyl amine resin, an acid, a co-solvent, and a balance of water. The glycidyl amine resin includes at least two epoxide groups, a phenyl group, and a tertiary amine group. The fixer composition may be included in a printing kit with an ink composition. In an example, the ink composition including a pigment, a polymeric binder, and an aqueous ink vehicle.

A textile printing ink jet ink composition includes a dioxazine pigment, a resin particle, and a lubricant, wherein the content of the dioxazine pigment is 0.5 to 1.5 mass % based on the total amount of the ink composition.

A textile printing ink jet ink composition includes a dioxazine pigment, a resin particle, and a lubricant, wherein the content of the dioxazine pigment is 0.5 to 1.5 mass % based on the total amount of the ink composition.

The present disclosure pertains to an aqueous inkjet ink containing a pigment as colorant, a polymeric dispersant, a polymeric binder, and a water-insoluble additive. The inks show improved properties for printing on paper and textile.

The disclosure provides a method for improving the strength and dyeing of wool fibers, and belongs to the technical field of modification of textile materials. By using the feature that protein fiber macromolecules contain a large number of active groups such as hydroxyl groups, amino groups and carboxyl groups, which easily react with polyphenolic pigments formed by a phenolic compound catalyzed by an enzyme to form covalent bonding, the disclosure realizes low temperature dyeing of wool fibers while improving the fiber strength. The disclosure has mild operating conditions easy to control, and in view of increasingly emphasis on environmental protection nowadays, the use of the biological enzyme for dyeing wool fibers is safe, environmentally friendly and efficient, and has a long-term development prospect.

A method for producing a printed product is provided. The method capable of producing the printed product is superior in a friction fastness and a texture. And, a printing system is also provided. The method includes a printing step in which an ink composition for inkjet, containing a colorant and a crosslinkable binder component, is inkjet-printed onto a textile good to obtain a print body; and a heat-treatment step in which, by heat-treatment of the print body with steam, the crosslinkable binder component is caused to melt or soften, and to crosslink to be a film, thereby fixing the colorant to fibers of the textile good. The printing system includes a printing apparatus and a heat-treatment equipment with which a print body after printing is heat-treated with steam.

The invention generally relates to fabric dyeing, such as fabric dyeing using indigo or sulphur dyes. A process is provided which provides a dyed yarn having reduced dye penetration and a white core. The process involves modification of existing sulfur dye ranges to more efficiently and in an environmentally improved method produce dyed fabrics. The modification involves one or more of i) using of a barrier compound to subsequent dye applications; ii) performing a scouring stage without a caustic agent; iii) bypassing scouring and/or scour rising; iv) using sodium bicarbonate to control the pH of dye tanks; v) reducing the dye concentration and increasing the number of dye vats; and vi) adding a sizing stage to the dye range. The invention also is directed to yarns dyed on dye ranges through use of the process, and fabrics formed from the dyed yarns.

The present invention is directed to a nanoporous cerium oxide nanoparticle (NCeONP) macro-structure containing a plurality of the cerium oxide nanoparticles which define a plurality of macro-structure pores. The NCeONP macro structure may be used to improve pigment and/or dye performance.
