Provided herein is a water-based metallic ink composition specifically adapted for direct digital inkjet printing on non-while fabrics and textile, which affords high resolution, high gloss and high luster metallic effect (high flop index) in decorations and designs that are wash-fast and stretchable. Also provided are processes of using the metallic ink compositions with other colored ink composition in direct digital inkjet printing on textile.

A dye additive suitable for use in improving the dyeing of aramid fibers includes non-water components dissolved in water. The non-water components include about 20-25% (w/w) sodium or potassium nitrate; about 20-25% (w/w) ketone solvent; about 30-40% (w/w) aromatic solvent; about 1-5% (w/w) of each of glycol ether, biodegradable solvent, acetic acid 56% strength or equivalent or equivalent amount of formic acid, brine salt, sodium or potassium hydroxide, and phenylenediamine, about 1-10% (w/w) of each of a strong acid, hydroxycarboxylic acid, and lanolin; wherein the water makes up about 50-70% of the weight of the dye additive and the non-water components make up about 30-50% of the dye additive. The dye additive may be added to a dye bath at a w/w percentage of about 0.25% to about 6%.

A nonwoven wipe having a reversible sanitizer indicator for multiple uses and recharges is provided. The nonwoven wipe includes a cloth-like nonwoven fabric coated with a reversible color-changing ink formulation. During use, the nonwoven wipe is impregnated with a quaternary ammonium compound-based sanitizer. When the level of free quaternary ammonium compound falls below a threshold level, the color-changing ink formulation changes from a first color to a second color, indicating the need to recharge the wipe. When the nonwoven wipe is recharged with sanitizer solution, the color-changing ink formulation changes back to the first color.

A method is disclosed for producing denim-effect garments by the following steps: 1) printing a reactive dye ink onto a PET film to form a pattern thereby obtaining a transfer printed PET film; 2) transfer printing a base pulp-treated fabric by attaching the transfer printed PET film thereby obtaining a denim-effect fabric; 3) cutting, sewing, washing to soften, and drying the denim-effect fabric and thereby obtaining a denim-effect garment. The method has the advantages of simple production, being environmentally friendly, having high efficiency, and being suitable for flexible fabrics, and the produced denim-effect garment of the invention has the advantages of having a good color fastness to rubbing, washing resistance, and having a diversity of patterns, and are suitable for large-scale production and application.
