     DETAILED DESCRIPTION 
     Described herein are an inkjet ink and related methods for the related preparation and use in printing and dyeing fabrics, and related compositions, printed fabric, methods and systems. 
     The term “ink” as used herein indicates a gel, sol, or solution that contains at least one colorant, such as a dye or pigment, and is used to color a surface to produce an image, text, or design. Ink formulas vary, but commonly involve two components including Colorants and Vehicles. Suitable colorants comprise pigments and dye. The vehicles usually comprise binders. Inks in the sense of the disclosure can be in an aqueous liquid paste and/or powder form depending on the colorant and vehicle used as will be understood by a person with ordinary skills in the art. (Wikipedia-ink 2022) 
     The term “inkjet ink” as used herein indicates an ink in a formulation enabling application through nozzles on a substrate of interest. Inkjet inks comprises liquid ink that can be applied in the form of resultant ink droplets to form a pattern on the substrate. Inkjet ink may also comprise solid ink formulations, which usually are waxy ink with a consistency similar to a crayon, as will be understood by a person having ordinary skills in the art. Inkjet ink can be in either dye-based or pigmented forms as will be understood by a person having ordinary skills in the art. 
     The term “pigment” as used herein indicates a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Exemplary pigments comprise ochre, charcoal, and lapis lazuli as will be understood by a person with ordinary skill in the art. (Wikipedia-pigment 2022) 
     The term “dye” as used herein indicates a colored substance that chemically bonds to the substrate to which it is being applied. This property distinguishes dyes from pigments which do not chemically bind to the material they color. A dye in the sense of the disclosure is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber. Dyes are usually soluble in water whereas pigments are insoluble. Some dyes can be rendered insoluble with the addition of salt to produce a fake pigment as will be understood by a person with ordinary skills (Wikipedia-dye 2022) 
     Dyes in the sense of the disclosure can be classified, according to their solubility and chemical properties, as acid dyes, basic dyes, mordant dyes, vat dyes, and reactive dye. (Wikipedia-dye 2022) 
     In particular, in a reactive dye, a chromophore (an atom or group whose presence is responsible for the color of a compound) contains a substituent that reacts with the substrate. In reactive dyes, the covalent bonds that attach reactive dye to natural fibers make them among the most permanent of dyes. Reactive dyes have good fastness properties owing to the covalent bonding that occurs during dyeing and can be used for coloring various types of fabric such as cellulose fibers. wool and nylon; in the latter case they are applied under weakly acidic conditions. (Wikipedia-reactive-dye 2022) 
     Reactive dyes can react with a substrate at various temperatures as will be understood by a person with ordinary skills in the art. “Cold” reactive dyes, which can be applied at room temperature comprise Procion MX, Cibacron F, and Drimarene K. as will be understood by a skilled person (Wikipedia-reactive-dye 2022). 
     Exemplary reactive dyes are reported in Table 1 below with corresponding fixation process and temperature as will be understood by an ordinary skilled person in the art

     In this case, the Color Fixation Rate′ is the color fixation rate of the inkjet inks in Examples 1-6 on the rayon cloth, and the conditions for steaming include: 102° C. *3 mins, the rayon cloth is pre-treated with the primer, and the composition of the primer comprises: 0.5% sodium bicarbonate, 2% sodium alginate, 8% urea, and 1% reserve salt; the Color Fixation Rate 2  is the color fixation rate of the conventional K type reactive inkjet ink on the rayon, wherein the conventional K type reactive inkjet ink is a monochloro-s-triazine reactive inkjet ink, and the conditions for steaming include: 102° C. *10 mins, the rayon cloth is pre-treated with the primer, and the composition of the primer comprises: 3% sodium bicarbonate, 2% sodium alginate, 8% urea, and 1% reserve salt. 
     It can be seen from Table 3 that the color fixation rates of the inks prepared in Examples 1-6 are all over 90%, and even up to 95%, while the color fixation rate of the used conventional K type reactive inkjet ink is about 70%. Therefore, compared with the conventional K type reactive inkjet ink, the inkjet inks in Examples 1-6 of the present disclosure have high color fixation rate and very little unfixed dye after color-fixing. Hence, in the subsequent water washing, a very small amount of water is needed to remove and clean the unfixed dye, thereby avoiding the phenomenon of fabric color fading and unfixed dye and so on. 
     Example 10 Performance Test—Color Fastness Test 
     The color fastness of the fabrics dyed by the inkjet inks in Examples 1-6 was tested using a color fastness tester, and the specific test results are shown in Table 4.

     It can be seen from Table 4 that the inkjet inks prepared in Examples 1-6 of the present disclosure have high color fastness and extremely high color fixation rate, and thus, even if it is not washed with water, the color fastness of the fabric samples printed by the inkjet inks in Examples 1-6 is relatively high, the fabric samples can be used directly without washing, and can also meet the color fastness requirements of clothing when used directly. And, after being washed once with cold water, the color fastness of the inkjet inks in Examples 1-6 is better, and approximately 0.5 level of the water washing and wet rubbing fastness can be further increased. In contrast, the conventional K type reactive ink needs 4-8 times of water washing and soaping at high temperature after steaming, so as to obtain relatively high color fastness. Accordingly, the inkjet ink prepared in accordance with several embodiments of the present disclosure can be washed without water, and only needs a very small amount of water even if it is washed with water, which can save a large amount of consumption of water, electricity and steam and meet the requirements of environmental protection. For the patterns printed by the inkjet inks in Examples 1-6 of the present disclosure, almost all the unfixed dye can be removed after washed once with cold water, and there is almost no unfixed dye in the subsequent soaping process (washing with the soap solution at 95° C.); this demonstrates that the fabric printed by the inkjet ink according to the present disclosure does not need to be washed with water or only needs a very short water washing process to achieve satisfactory washing fastness. However, the conventional K type reactive ink requires a relatively long time and multiple steps of water washing-soaping processes. Therefore, compared with the conventional K type reactive ink, embodiments of the present disclosure have the advantages of saving time and saving water, electricity and steam, effectively. 
     Example 11 Performance Test—Storage Stability 
     The pH, surface tension, electrical conductivity and other indicators of six inkjet inks prepared in Examples 1-6 were tested, respectively. The pH values of the inkjet inks prepared in Examples 1-6 are shown in Table 5; the surface tension data is shown in Table 6, and the surface tension was tested with QBZY series automatic surface tensiometer; and the electrical conductivity data is shown in Table 7, and the electrical conductivity was tested with a METTLER TOLEDO LE703 conductivity meter.

     It can be seen from Tables 5-7 that the electrical conductivity and surface tension of the inkjet inks prepared in Examples 1-6 barely changed within a storage period of 3 months, while the variation trend of pH values varied with the reactive dyes used. In these cases, the pH value of the inkjet ink which was royal blue in Example 5 decreased to 5.88 after 1 month of storage, and decreased to 5.45 after 3 months of storage. The pH stability of the magenta and black inks was high, and the pH value barely changed within the storage period of 3 months, and thus the usage period of the magenta and black inks can be set to more than 3 months. The pH value of the inks which were other colors decreased within the storage period of 3 months, but was still above 5.5, which was still in a safe range for a print nozzle, and thus the usage period of them can be set within 3 months. 
     The embodiments of the present disclosure have been described in details above, but the present disclosure is not limited to the above embodiments, various modifications can also be made within the scope of knowledge possessed by those skilled in the art, without departing from the purpose of the present disclosure. Furthermore, embodiments of the present disclosure and features in the embodiments may be combined with each other in the absence of conflicts. 
     The examples set forth above are provided to give those of ordinary skill in the art a complete disclosure and description of how to make and use the embodiments of the inkjet ink, materials, compositions, systems and methods of the disclosure, and are not intended to limit the scope of what the inventors regard as their disclosure. Modifications of the above-described modes for carrying out the disclosure that are obvious to persons of skill in the art are intended to be within the scope of the following claims. All patents and publications mentioned in the specification are indicative of the levels of skill of those skilled in the art to which the disclosure pertains. 
     The entire disclosure of each document cited (including patents, patent applications, journal articles, abstracts, laboratory manuals, books, or other disclosures) in the Background, Summary, Detailed Description, and Examples is hereby incorporated herein by reference. All references cited in this disclosure are incorporated by reference to the same extent as if each reference had been incorporated by reference in its entirety individually. The webpages referred in the instant disclosure are the webpages available at the filing date of the present disclosure as will be understood by a skilled person. 
     It is to be understood that the disclosures are not limited to particular compositions materials, or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. The term “plurality” includes two or more referents unless the content clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosure pertains. 
     Unless otherwise indicated, the disclosure is not limited to specific reactants, substituents, catalysts, reaction conditions, or the like, as such may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. 
     As used in the specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a dye” includes a single dye as well as a combination or mixture of two or more dye, reference to “a substituent” encompasses a single substituent as well as two or more substituents, and the like. 
     As used in the specification and the appended claims, the terms “for example,” “for instance,” “such as,” or “including” are meant to introduce examples that further clarify more general subject matter. Unless otherwise specified, these examples are provided only as an aid for understanding the applications illustrated in the present disclosure, and are not meant to be limiting in any fashion. 
     In this disclosure and in the claims that follow, reference will be made to a number of terms, which shall be defined to have the following meanings: 
     The term “alkyl” as used herein refers to a linear, branched, or cyclic saturated hydrocarbon group typically although not necessarily containing 1 to about 10 carbon atoms, preferably 1 to about 6 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, t-butyl, octyl, decyl, and the like, as well as cycloalkyl groups such as cyclopentyl, cyclohexyl and the like. Generally, although again not necessarily, alkyl groups herein contain 1 to about 6 carbon atoms. The term “cycloalkyl” intends a cyclic alkyl group, typically having 4 to 8, preferably 5 to 7, carbon atoms. The term “substituted alkyl” refers to alkyl substituted with one or more substituent groups, and the terms “heteroatom-containing alkyl” and “heteroalkyl” refer to alkyl in which at least one carbon atom is replaced with a heteroatom. If not otherwise indicated, the terms “alkyl” and “lower alkyl” include linear, branched, cyclic, unsubstituted, substituted, and/or heteroatom-containing alkyl and lower alkyl, respectively. 
     The term “heteroatom-containing” as in a “heteroatom-containing alky group” refers to a alkyl group in which one or more carbon atoms is replaced with an atom other than carbon, e.g., nitrogen, oxygen, sulfur, phosphorus or silicon, typically nitrogen, oxygen or sulfur. Similarly, the term “heteroalkyl” refers to an alkyl substituent that is heteroatom-containing, the term “heterocyclic” refers to a cyclic substituent that is heteroatom-containing, the terms “heteroaryl” and “heteroaromatic” respectively refer to “aryl” and “aromatic” substituents that are heteroatom-containing, and the like. It should be noted that a “heterocyclic” group or compound may or may not be aromatic, and further that “heterocycles” may be monocyclic, bicyclic, or polycyclic as described above with respect to the term “aryl.” Examples of heteroalkyl groups include alkoxyaryl, alkylsulfanyl-substituted alkyl, N-alkylated amino alkyl, and the like. Examples of heteroaryl substituents include pyrrolyl, pyrrolidinyl, pyridinyl, quinolinyl, indolyl, pyrimidinyl, imidazolyl, 1,2,4-triazolyl, tetrazolyl, etc., and examples of heteroatom-containing alicyclic groups are pyrrolidino, morpholino, piperazino, piperidino, etc. 
     The term “alkoxy” as used herein intends an alkyl group bound through a single, terminal ether linkage; that is, an “alkoxy” group may be represented as —O-alkyl where alkyl is as defined above. A “lower alkoxy” group intends an alkoxy group containing 1 to 6 carbon atoms. Analogously, “alkenyloxy” and “lower alkenyloxy” respectively refer to an alkenyl and lower alkenyl group bound through a single, terminal ether linkage, and “alkynyloxy” and “lower alkynyloxy” respectively refer to an alkynyl and lower alkynyl group bound through a single, terminal ether linkage. 
     The term “aryl” as used herein, and unless otherwise specified, refers to an aromatic substituent containing a single aromatic ring or multiple aromatic rings that are fused together, directly linked, or indirectly linked (such that the different aromatic rings are bound to a common group such as a methylene or ethylene moiety). Preferred aryl groups contain 5 to 24 carbon atoms, and particularly preferred aryl groups contain 5 to 14 carbon atoms. Exemplary aryl groups contain one aromatic ring or two fused or linked aromatic rings, e.g., phenyl, naphthyl, biphenyl, diphenylether, diphenylamine, benzophenone, and the like. “Substituted aryl” refers to an aryl moiety substituted with one or more substituent groups, and the terms “heteroatom-containing aryl” and “heteroaryl” refer to aryl substituents in which at least one carbon atom is replaced with a heteroatom, as will be described in further detail infra. 
     The term “aryloxy” as used herein refers to an aryl group bound through a single, terminal ether linkage, wherein “aryl” is as defined above. An “aryloxy” group may be represented as —O-aryl where aryl is as defined above. Preferred aryloxy groups contain 5 to 24 carbon atoms, and particularly preferred aryloxy groups contain 5 to 14 carbon atoms. Examples of aryloxy groups include, without limitation, phenoxy, o-halo-phenoxy, m-halo-phenoxy, p-halo-phenoxy, o-methoxy-phenoxy, m-methoxy-phenoxy, p-methoxy-phenoxy, 2,4-dimethoxy-phenoxy, 3,4,5-trimethoxy-phenoxy, and the like. 
     The term “alkaryl” refers to an aryl group with an alkyl substituent, and the term “aralkyl” refers to an alkyl group with an aryl substituent, wherein “aryl” and “alkyl” are as defined above. In some embodiments, alkaryl and aralkyl groups contain 6 to 24 carbon atoms, and particularly alkaryl and aralkyl groups contain 6 to 16 carbon atoms. Alkaryl groups include, for example, p-methylphenyl, 2,4-dimethylphenyl, p-cyclohexylphenyl, 2,7-dimethylnaphthyl, 7-cyclooctylnaphthyl, 3-ethyl-cyclopenta-1,4-diene, and the like. Examples of aralkyl groups include, without limitation, benzyl, 2-phenyl-ethyl, 3-phenyl-propyl, 4-phenyl-butyl, 5-phenyl-pentyl, 4-phenylcyclohexyl, 4-benzylcyclohexyl, 4-phenylcyclohexylmethyl, 4-benzylcyclohexylmethyl, and the like. The terms “alkaryloxy” and “aralkyloxy” refer to substituents of the formula —OR wherein R is alkaryl or aralkyl, respectively, as just defined. 
     The term “acyl” refers to substituents having the formula —(CO)-alkyl, —(CO)-aryl, or —(CO)-aralkyl, and the term “acyloxy” refers to substituents having the formula —O(CO)-alkyl, —O(CO)-aryl, or —O(CO)-aralkyl, wherein “alkyl,” “aryl, and “aralkyl” are as defined above. 
     The terms “cyclic” and “ring” refer to alicyclic or aromatic groups that may or may not be substituted and/or heteroatom containing, and that may be monocyclic, bicyclic, or polycyclic. The term “alicyclic” is used in the conventional sense to refer to an aliphatic cyclic moiety, as opposed to an aromatic cyclic moiety, and may be monocyclic, bicyclic or polycyclic. 
     The terms “halo” and “halogen” are used in the conventional sense to refer to a chloro, bromo, fluoro or iodo substituent. 
     The term “polyether” as used herein indicates a structure containing multiple carbon-oxygen-carbon covalent linkages. 
     The term “olefins” as used herein indicates two carbons covalently bound to one another that contain a double bond (sp 2 -hybridized bond) between them. The other functional groups bound to each of these two carbons can be additional carbons, hydrogen atoms, or heteroatoms. 
     By “substituted” as in “substituted alkyl,” “substituted aryl,” and the like, as alluded to in some of the aforementioned definitions, is meant that in the alkyl, aryl, or other moiety, at least one hydrogen atom bound to a carbon (or other) atom is replaced with one or more non-hydrogen substituents. 
     Examples of such substituents include, without limitation: functional groups such as halo, hydroxyl, sulfhydryl, C 1 -C 24  alkoxy, C 2 -C 24  alkenyloxy, C 2 -C 24  alkynyloxy, C 5 -C 24  aryloxy, C 6 -C 24  aralkyloxy, C 6 -C 24  alkaryloxy, acyl (including C 2 -C 24  alkylcarbonyl (—CO-alkyl) and C 6 -C 24  arylcarbonyl (—CO-aryl)), acyloxy (—O-acyl, including C 2 -C 24  alkylcarbonyloxy (—O—CO-alkyl) and C 6 -C 24  arylcarbonyloxy (—O—CO-aryl)), C 2 -C 24  alkoxycarbonyl (—(CO)—O-alkyl), C 6 -C 24  aryloxycarbonyl (—(CO)—O-aryl), halocarbonyl (—CO)—X where X is halo), C 2 -C 24  alkylcarbonato (—O—(CO)—O-alkyl), C 6 -C 24  arylcarbonato (—O—(CO)—O-aryl), carboxy (—COOH), carboxylato (—COO − ), carbamoyl (—(CO)—NH 2 ), mono-(C 1 -C 24  alkyl)-substituted carbamoyl (—(CO)—NH(C 1 -C 24  alkyl)), di-(C 1 -C 24  alkyl)-substituted carbamoyl (—(CO)—N(C 1 -C 24  alkyl) 2 ), mono-(C 5 -C 24  aryl)-substituted carbamoyl (—(CO)—NH-aryl), di-(C 5 -C 24  aryl)-substituted carbamoyl (—(CO)—N(C 5 -C 24  aryl) 2 ), di-N-(C 1 -C 24  alkyl),N-(C 5 -C 24  aryl)-substituted carbamoyl, thiocarbamoyl (—(CS)—NH 2 ), mono-(C 1 -C 24  alkyl)-substituted thiocarbamoyl (—(CO)—NH(C 1 -C 24  alkyl)), di-(C 1 -C 24  alkyl)-substituted thiocarbamoyl (—(CO)—N(C 1 -C 24  alkyl) 2 ), mono-(C 5 -C 24  aryl)-substituted thiocarbamoyl (—(CO)—NH-aryl), di-(C 5 -C 24  aryl)-substituted thiocarbamoyl (—(CO)—N(C 5 -C 24  aryl) 2 ), di-N-(C 1 -C 24  alkyl),N-(C 5 -C 24  aryl)-substituted thiocarbamoyl, carbamido (—NH—(CO)—NH 2 ), cyano(—C≡N), cyanato (—O—C≡N), thiocyanato (—S—C≡N), formyl (—(CO)—H), thioformyl (—(CS)—H), amino (—NH 2 ), mono-(C 1 -C 24  alkyl)-substituted amino, di-(C 1 -C 24  alkyl)-substituted amino, mono-(C 5 -C 24  aryl)-substituted amino, di-(C 5 -C 24  aryl)-substituted amino, C 2 -C 24  alkylamido (—NH—(CO)-alkyl), C 6 -C 24  arylamido (—NH—(CO)-aryl), imino (—CR═NH where R=hydrogen, C 1 -C 24  alkyl, C 5 -C 24  aryl, C 6 -C 24  alkaryl, C 6 -C 24  aralkyl, etc.), C 2 -C 20  alkylimino (—CR═N(alkyl), where R=hydrogen, C 1 -C 24  alkyl, C 5 -C 24  aryl, C 6 -C 24  alkaryl, C 6 -C 24  aralkyl, etc.), arylimino (—CR═N(aryl), where R=hydrogen, C 1 -C 20  alkyl, C 5 -C 24  aryl, C 6 -C 24  alkaryl, C 6 -C 24  aralkyl, etc.), nitro (—NO 2 ), nitroso (—NO), sulfo (—SO 2 —OH), sulfonato (—SO 2 -01, C 1 -C 24  alkylsulfanyl (—S-alkyl; also termed “alkylthio”), C 5 -C 24  arylsulfanyl (—S-aryl; also termed “arylthio”), C 1 -C 24  alkylsulfinyl (—(SO)-alkyl), C 5 -C 24  arylsulfinyl (—(SO)-aryl), C 1 -C 24  alkylsulfonyl (—SO 2 -alkyl), C 5 -C 24  arylsulfonyl (—SO 2 -aryl), boryl (—BH 2 ), borono (—B(OH) 2 ), boronato (—B(OR) 2  where R is alkyl or other hydrocarbyl), phosphono (—P(O)(OH) 2 ), phosphonato (—P(O)(O − ) 2 ), phosphinato (—P(O)(O − )), phospho (—PO 2 ), phosphino (—PH 2 ), silyl (—SiR 3  wherein R is hydrogen or hydrocarbyl), and silyloxy (—O-silyl); and the hydrocarbyl moieties C 1 -C 24  alkyl (preferably C 1 -C 12  alkyl, more preferably C 1 -C 6  alkyl), C 2 -C 24  alkenyl (preferably C 2 -C 12  alkenyl, more preferably C 2 -C 6  alkenyl), C 2 -C 24  alkynyl (preferably C 2 -C 12  alkynyl, more preferably C 2 -C 6  alkynyl), C 5 -C 24  aryl (preferably C 5 -C 14  aryl), C 6 -C 24  alkaryl (preferably C 6 -C 16  alkaryl), and C 6 -C 24  aralkyl (preferably C 6 -C 16  aralkyl). 
     In addition, the aforementioned functional groups may, if a particular group permits, be further substituted with one or more additional functional groups or with one or more hydrocarbyl moieties such as those specifically enumerated above. Analogously, the above-mentioned hydrocarbyl moieties may be further substituted with one or more functional groups or additional hydrocarbyl moieties such as those specifically enumerated. 
     The term “distal” as used herein indicates substitution in the para-position (aryl rings), or at the farthest possible point of attachment from the point of origin (cyclic alkyl ring). 
     “Optional” or “optionally” means that the subsequently described circumstance may or may not occur, so that the description includes instances where the circumstance occurs and instances where it does not. For example, the phrase “optionally substituted” means that a non-hydrogen substituent may or may not be present on a given atom, and, thus, the description includes structures wherein a non-hydrogen substituent is present and structures wherein a non-hydrogen substituent is not present. 
     In the molecular structures herein, the use of bold and dashed lines to denote particular conformation of groups follows the IUPAC convention. A bond indicated by a broken line indicates that the group in question is below the general plane of the molecule as drawn, and a bond indicated by a bold line indicates that the group at the position in question is above the general plane of the molecule as drawn. 
     The term “carbon chain” as used herein indicates a linear or branched line of connected carbon atoms. 
     Although any methods and materials similar or equivalent to those described herein can be used in the practice for testing of the specific examples, additional appropriate materials and methods are described herein. 
     A number of embodiments of the disclosure have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the present disclosure. Accordingly, other embodiments are within the scope of the following claims.
