An activated cotton material and a method for processing cotton to form the activated cotton material are provided. The activated cotton material includes a layer of natural wax that is locked to the surface of cotton fibers by a wax lock.

An inkjet textile printing treatment liquid contains an aqueous medium and a pH sliding agent. An inkjet textile printing apparatus includes a recording head that ejects an ink toward an image formation area of a textile printing target and a first treatment head that ejects a first treatment liquid toward at least the image formation area of the textile printing target. The first treatment liquid is the above-described inkjet textile printing treatment liquid. An inkjet textile printing method incudes: inkjetting an ink toward an image formation area of a textile printing target; and inkjetting a first treatment liquid toward at least the image formation area of the textile printing target. The first treatment liquid is the above-described inkjet textile printing treatment liquid.

A decolorization method of a polyester fabric includes: providing a polyester fabric, in which the polyester fabric is a dyed polyester fabric and the polyester fabric is adhered with a dye and has a first L value; providing a first decolorizing solution and a second decolorizing solution, in which the first decolorizing solution contains a reductant and the second decolorizing solution contains an oxidant; and performing a decolorization process which includes: using one of the first decolorizing solution and the second decolorizing solution to decolorize one portion of the dye and using another one of the first decolorizing solution and the second decolorizing solution to decolorize another portion of the dye, so that a color of the dye is removed and the polyester fabric is white in color and has a second L value that is greater than the first L value.

The present disclosure provides an ink fluid set containing an aqueous pre-treatment composition, a clear ink, and colored aqueous inkjet inks. This ink fluid set is particularly suitable for printing on polyester, cotton, and blends of cotton and synthetic textiles.

Described are methods and systems for cationizing and dyeing a natural fiber-containing textile, which uses a mono- or di-quaternized cationizing agent. The method includes a step of heating the textile to a temperature in the range of 90° C. to less than 110° C. for a period of time in the range of 1 min to 10 min to react the cationizing agent with the textile. The cationization step in the presence of heat using the halogenated cationization agent of the invention facilitates improved dyeing.

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.

A fabric print medium containing a fabric base substrate and a primer layer composition applied to the fabric base substrate. Said primer layer composition includes at least three types of polymeric particles, at least two different fire retardant agents and a water-soluble high-valence metal complex. Also disclosed are the method for making such fabric print medium and the method for producing printed images using said material.

An activated cotton material and a method for processing cotton to form the activated cotton material are provided. The activated cotton material includes a layer of natural wax that is locked to the surface of cotton fibers by a wax lock.

The present invention relates generally to compositions and methods for oxidizing or discoloring garments, such as denim. Another aspect relates to providing a cost-effective and environmentally safe alternative to hazardous bleaching agents, such as potassium permanganate.
