A method for dyeing, such as vat dyeing, or coating synthetic fibers, such as polyester fibers and/or polyamide fibers, or yarns or fabrics including these fibers can include providing a powdered dye or a powdered precursor dye (powdered leuko dye), or providing an aqueous dye formulation or an aqueous precursor dye formulation (an alkaline aqueous leuko dye formulation). An aqueous system including a lipase enzyme can be provided. The fibers/yarn/fabric can be pretreated with the aqueous system, and the pretreated fibers/yarn/fabric can be coated or dyed with the powdered dye or powdered precursor dye, or with the aqueous dye formulation or aqueous precursor dye formulation.

Method for manufacturing artificial leather having excellent fastness and dyeing properties by using a dope-dyed polyester sea-island type composite yarn and artificial leather produced by the method are disclosed. A non-woven fabric is made of a dope-dyed polyester sea-island type composite yarn, to which an organic pigment and/or inorganic pigment is added. The yarn is impregnated with a polyurethane resin containing an organic and/or inorganic pigment, followed by weight reduction processing and dying with a disperse dye. The fabric/artificial leather expresses an uniform and deep color.

A dye-releasing product for dyeing of or for refreshing of dyeing in textile materials is provided. The dye-releasing product includes a flat, cloth-like carrier material, and at least one coating applied onto the carrier material. At least one indigoid dye in its oxidized form is encompassed by the coating. The coating contains at least one binding agent for the at least one indigoid dye such that the at least one indigoid dye is released in an aqueous solution with a temperature equal to or greater than 20 C. that is, the coating is soluble, at least in part from the flat, cloth-like carrier material, which is added to the textile material to be dyed or whose dyeing is to be refreshed in a washing process.

Disclosed is an artificial leather base material having a surface with a lightness L* value of 50 and including a fiber base material that includes cationic dye-dyeable polyester fibers and an elastic polymer, the artificial leather base material being dyed with at least one cationic dye. Also provided is a resin layer-equipped artificial leather, a napped artificial leather, and a shoe that use the artificial leather base material is used. Also provided is a decorating sheet including the artificial leather base material, and a decorative molded body using the same.

A decorative sheet includes a fiber base material and a first pattern. The first pattern decorates a surface of the fiber base material. The first pattern is formed by a resin portion made of resin. The resin portion adheres to the surface of the fiber base material. In the first pattern, a height of the resin portion from the surface of the fiber base material changes on the surface of the fiber base material.

A dye-releasing product for dyeing of or for refreshing of dyeing in textile materials is provided. The dye-releasing product includes a flat, cloth-like carrier material, and at least one coating applied onto the carrier material. At least one indigoid dye in its oxidized form is encompassed by the coating. The coating contains at least one binding agent for the at least one indigoid dye such that the at least one indigoid dye is released in an aqueous solution with a temperature equal to or greater than 20 C. that is, the coating is soluble, at least in part from the flat, cloth-like carrier material, which is added to the textile material to be dyed or whose dyeing is to be refreshed in a washing process.

A protective textile sleeve for providing protection to an elongate member contained therein and method of construction thereof are provided. The sleeve has a wall formed of interlaced yarn(s) and a coating of elastomeric material bonded to an outer surface of the wall. The coating has an indicia therein to provide a viewer viewing an outer surface of the coating with information, wherein the indicia extends radially inwardly into the outer surface of the coating to provide the indicia with depth so as to avoid being easily worn away.

Disclosed is a leather-like sheet having a surface configured such that, when an L* value, a C* value, and an h value under illumination of a D65 light source are represented as L*.sub.D65, C*.sub.D65, and h.sub.D65, and an L* value, a C* value, an h value under illumination of an F10 light source are represented as L*.sub.F10, C*.sub.F10, and h.sub.F10, L*.sub.D65 is 30 to 95, and at least one selected from a condition |C|=|C*.sub.F10C*.sub.D65|7, and a condition |h|=|h.sub.F10h.sub.D65|7 is satisfied.

A construct, for use in articles like apparel, footwear, backpacks, etc., the construct including a substrate, e.g., a textile, foam, leather or rubber material, having a surface of plasma transformed textile material; colorant set in the plasma transformed textile material, providing a change to the color of the underlying substrate material; and wherein the colorant and the plasma transformed substrate material are chemically bonded together.

A method of treating a substrate, comprising providing a substrate having a generally sheet or planar form or a fiber or yarn form; providing a colorant to be set at the surface of the substrate; and subjecting the substrate and colorant to reactive species from a plasma generated by an atmospheric plasma apparatus until the colorant is set at the surface of the substrate. A method of setting a colorant on a substrate, comprising performing an etch operation, or plasma pre-treatment to change surface charge, on a substrate using a plasma, particularly a plasma generated at atmospheric conditions, to create a desired surface texture, or surface charge, at the surface of substrate; and depositing a colorant on the surface under plasma or non-plasma conditions; and allowing the colorant to set at the surface of the substrate.
