The present invention relates to a waterless fiber dyeing method using a mixed fluid medium, in which supercritical carbon dioxide fluid medium is mixed with steam to form a mixed fluid medium, so that the waterless fiber dyeing effect to natural fibers is improved. The method of the invention can effectively modify the hydrophobic supercritical carbon dioxide fluid medium and improve the polarity thereof, thereby increasing the solubility of polar dye under the dyeing condition and simultaneously expanding the fiber. Thus, the present invention significantly improves the dyeability and dyeing behavior of the hydrophilic fibers in supercritical carbon dioxide fluids. The invention has the advantages of simple process, convenient operation and low energy consumption, and avoids consuming a large amount of water resources and discharging pollutants in the traditional process, and has the characteristics of environmentally friendly and high efficiency.

A face mask kit has one or more face masks, each face mask having a facial covering configured to be colored; and at least one colored dye for applying to the facial covering to impart a color. The facial covering is a fabric of a neutral base color to be dyed with the at least one colored dye, the neutral base color is preferably white. The at least one colored dye includes a plurality of colored dyes of different colors, the plurality of colored dyes includes colors selected from colors of red, yellow, blue, orange, green or pink. The face mask kit further has at least one flavored-scent configured to be applied to the facial covering to impart a fragrance to the mask.

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.

The present invention relates to a process for the production of a dyed biopolymer comprising the steps of providing at least one biopolymer-producing microorganism, providing at least one dye-producing microorganism, culturing said at least one biopolymer-producing microorganism to produce at least a biopolymer, and culturing said dye-producing microorganism wherein said dye-producing microorganism produce at least a dye suitable to dye at least part of said biopolymer, whereby a dyed biopolymer is obtained. The present invention also relates to a dyed biopolymer, to process for the production of a dyed composite article comprising at least the dyed biopolymer and to articles comprising the dyed biopolymer.

Provided is an enzymatic treatment on polyester/cellulose blend textile by contacting the textile with a cutinase and preferable with cellulose as well.

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.

Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image.

A dye composition and a dyeing method for an elastic fabric are provided. The dyeing method includes: (a) providing an elastic fabric which includes an elastic fiber; and (b) immersing the elastic fabric in a dye composition. The dye composition includes an ion modifier and a dye. The elastic fiber of the elastic fabric has a first ion by contacting the ion modifier, and the first ion has a first charge; the dye has a second ion, and the second ion has a second charge opposite to the first charge. The first ion of the elastic fiber and the second ion of the dye together form an ionic bonding.

A liquid application unit includes a supply member, a liquid application device, and an application controller. The supply member includes a cylindrical or columnar winding core around which a linear medium is wound. The liquid application device applies liquid to the linear medium unwound and fed from the supply member. The application controller adjusts a liquid application length of the liquid applied by the liquid application unit to the linear medium in a feed direction of the linear medium. The application controller adjusts the liquid application length in the feed direction of the linear medium in accordance with a winding thickness of a remaining amount of the linear medium from an outer peripheral surface of the winding core.

A method of making a tie dye solution for a fabric includes adding a first predetermined weight of sodium chloride to a second predetermined weight of a dye, wherein the first predetermined weight of the sodium chloride is based on the color of the dye. The method further includes mixing the first predetermined weight of the sodium chloride and the second predetermined weight of the dye together to form a dry dye mixture, dispensing the mixed first predetermined weight of the sodium chloride and the second predetermined weight of the dye into a dye bottle, and adding water to the dye bottle having the mixed first predetermined weight of the sodium chloride and the second predetermined weight of the dye to form the tie dye solution.
