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 textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a textile material comprising yarns which contain an intimate blend of polyphenylene sulfide fibers and cellulosic fibers, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180° C. or more to fix the disperse dye to the polyphenylene sulfide fibers.

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 textile dyeing process is described for dyeing a textile material, product or article consisting of animal fibers, comprising the steps of dipping said textile material, product or article into a dyeing bath comprising at least one detergent substance, a wetting substance, a leveling substance and an acidity regulator; adding to the dyeing bath a coloring substance approved for food use; subjecting the dyed textile material, product or article to washes; and finally subjecting the dyed textile material, product or article to a color fixing treatment.

A printing method contains applying a processing fluid to a fabric and applying an ink to the fabric to which the processing fluid has been applied, wherein the ink contains a pigment, a resin having a cross-linkable functional group, a pH regulator, and at least one member selected from a block isocyanate compound, a carbodiimide compound, and a polymer having an oxazoline group.

A pretreatment liquid for a fabric used for transfer textile printing, includes a solvent having an organic/inorganic value (I/O value) of 1.0 to 3.0, and has a surface tension of less than 38 mN/m at 25° C.

A treatment liquid composition contains water, 1,2-alkanediol, and an aggregating agent aggregating or thickening components of an ink composition containing a pigment and is used for a printing method performed by causing the ink composition to adhere to cloth by an ink jet method.

An ink jet textile printing method includes recording by applying an ink composition containing a dye to a front surface of a fabric by an ink jet method and applying a liquid penetrant to the front surface or a rear surface of the fabric before or after the recording. The liquid penetrant includes a nitrogen compound having a boiling point of 230 to 260° C. and an alkyl polyol having a boiling point of 230 to 260° C. and does not substantially include alkyl polyols having a boiling point higher than 260° C.

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.

A method of combatting colour loss from a dyed material, the method comprising the steps of: (1) contacting the material with a composition comprising an electrophilic species selected from aldehydes, succinimidyl esters, and mixtures thereof; (2) contacting the material with a composition comprising a chelating agent and/or a salt of an amine and/or a carboxylic acid.
