A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

A method for manufacturing a fabric with an intelligently-designed digitally-printed pattern with energy saving effect is disclosed. The method includes S1 knitting: combining cotton yarn, bamboo fiber yarn, and mulberry silk yarn to form a double strand yarn, and knitting the double strand yarn into a silk-cotton plain knitted single-sided fabric; S2 singeing: subjecting the fabric obtained in step S1 to a double-sided singeing; S3 mercerizing: mercerizing the fabric obtained in step S2 by utilizing a knitting mercerizing machine; S4 boiling: subjecting the mercerized fabric obtained in step S3 to a neutralizing processing, a bleaching processing, a deoxidating processing, and a whitening processing in sequence; S5 setting a base color: setting the base color of the fabric obtained in step S4; S6 printing: subjecting the fabric obtained in step S5 to a sizing and setting treatment, a pattern design treatment, a digital printing, a steaming treatment, and a water washing treatment; S7 soft setting: subjecting the fabric obtained in step S6 to a soft setting by utilizing a setting machine; S8 decating treatment: subjecting the fabric obtained in step S7 to a decating treatment; and S9 pre-shrinking treatment: pre-shrinking the fabric obtained in S8 by utilizing a pre-shrinking machine.

The present disclosure describes fluid sets for printing, methods of textile printing, and textile printing systems. In one example, a fluid set for printing can include a pretreat composition, a fixer composition, and a white ink composition. The pretreat composition can include water and an emulsion of a silicone polymer having amino groups. The fixer composition can include a liquid vehicle and a cationic polymer. The white ink composition can include a liquid vehicle, a white pigment dispersion, and a polymeric binder.

In an example of the disclosure, a print job is received. The print job includes an image to be printed upon a substrate utilizing printheads. The print job is analyzed to determine a set of imaged segments, a set of image-adjacent segments, and a set of remote segments. The print job is printed upon the substrate utilizing a first set of printheads. A cooling liquid is applied to the set of image-adjacent segments of the printed print job utilizing a second set of printheads downstream from the first set of printheads. The printed job is exposed to an array of controllable illumination elements. The array of illumination elements is controlled to apply a drying illumination to the imaged segments and the image-adjacent segments of the printed print job, without providing the drying illumination to the remote segments.

An ink set for textile printing is disclosed which includes a pretreatment liquid containing a metal salt, a water-dispersible resin (A), an organic solvent (B) having an SP value of 10 to 14 (cal/cm.sup.3).sup.1/2 and water, and an ink containing a pigment, a water-dispersible resin (C) having a glass transition point of 10° C. or higher, an organic solvent (D) and water. A method for producing a printed textile item is also disclosed.

A treatment liquid composition for ink jet pigment printing is a treatment liquid composition which is used to be adhered to a cloth and which includes a block isocyanate compound, a hydroxyethyl cellulose, and a cationic compound.

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.

A dye printing method and an ink capable of performing printing on more types of media than in the related art are shown. A dye printing method using ink 10 containing a solvent 11, and particles of a thermoplastic resin dispersed in the solvent 11 and containing a dye 13 is characterized by including a printing process of performing a printing on a medium 20 with the ink 10, a particle fixing process of fixing the particles 12 to the medium 20 by drying the solvent 11 of the ink 10 ejected to the medium 20 by the printing process, and a resin fixing process of fixing the thermoplastic resin to the medium 20 by heating the particles 12 fixed to the medium 20 by the particle fixing process, at least at a glass-transition temperature or higher.

The invention relates to a dye system comprising at least one dye precursor, an oxidizing agent, and a catalyst. The dye system operates, ideally, at a pH of at least about 9. The dye system may enable faster and less damaging hair color treatment techniques. The invention further relates to methods for making and using said dye system.
