The present invention provides a process for the production of a fabric having a unique appearance and the fabric so obtained. Also provided is the clothing articles, i.e. garments, including the fabric. More particularly, the present invention relates to a process for producing a woven fabric having a unique, e.g. “used” (i.e. worn-out) or “multi-shaded” appearance and the process includes a step of providing a woven fabric with a layer of bacterial biopolymer, dyeing at least part of the fabric together with the biopolymer layer, and then removing at least part of the bacterial biopolymer layer from the fabric.

Provided is a process for the production of a dyed fabric using enzyme aggregates. In particular, provided is a process that comprises a step of providing a woven fabric that comprises a base layer and an additional layer which is located on at least one side of the fabric, wherein the yarns of the additional layer comprise fibers that are at least partially dyed, and a step of contacting the woven fabric with enzyme aggregates such as cross-linked enzyme aggregates (CLEAs), to remove at least part of the dye from at least the yarns of said additional layer. The disclosure also provides a fabric obtained with the process and garments including the fabric.

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 dyeing and finishing method for linen cotton textile fabric with high-shrinkage is described in the present invention, comprises the steps as below: preprocessing, pickling, dyeing and shaping, which can make the fabric with sufficient shrinkage and provide a qualitative sense of linen cotton. Through the above way, in the dyeing and finishing method for linen cotton textile fabric with high-shrinkage provided by the present invention, washing treatment on the fabric by the preprocessing and the pickling before dyeing makes the colorizing more easy and decreases the color difference and colored spot after dyeing, opening the fiber of the fabric and cooling shrinkage during the dyeing process can obtain the unique product style, with a handle more like the linen cotton effect, and a pellet feeling appeared on the cloth cover and the product fabric more like the woven fabric.

[Problem] The present invention addresses the problem of providing: a method for producing garments that use dyed cloth on which whiteness easily emerges due to heating by irradiation with laser or the like and which can be efficiently decolorized; dyed cloth used in production of decolorized garments; and a chemical agent used in decolorization of dyed cloth. [Solution] This production method for garments is characterized by using a heat treatment to decolorize garments which use dyed cloth containing an alkanolamine. The temperature of the heat treatment is preferably 160-180° C., and the heat treatment is more preferably a laser machining treatment.

The present disclosure provides dye compounds for use in dyeing textiles.

A fabric has enhanced response characteristics for laser finishing. The fabric can be denim for denim apparel such as jeans. Software and lasers are used to finish apparel made of the fabric to produce a desired wear or distressing pattern or other design. The fabric allows for relatively fast color change in response to the laser, color changes in hue from indigo blue to white, many grayscale levels, and maintains strength and stretch properties. A method used to make the fabric includes spinning, dyeing, and weaving yarns in such a way to obtain the desired enhanced response characteristics for laser finishing.

Described herein are compositions including O,O′-diacetyl leucoindigo. Also described herein are methods of pre-dyeing fibers with O,O′-diacetyl leucoindigo, followed by developing the pre-dyed fibers using hydrolysis or oxidation conditions to form indigo-dyed fibers. Also disclosed are indigo-dyed fibers, textiles, and fabrics made using O,O′-diacetyl leucoindigo, wherein cellulose, polyester, polyacrylonitrile, nylon, wool, and other compositional fiber types are suitably dyed with indigo dye using the described compositions and methods.

Methods for processing denim are provided. An initial fabric is abraded by passing the initial fabric through an abrader at a first predetermined speed, thereby obtaining a pre-washed fabric with an abraded texture. The abrader comprises one or more sanding boards, where each respective sanding board has a respective diamond surface that contacts the initial fabric while spinning about a respective axis at the respective center of the respective sanding board during the abrading. The pre-washed fabric is then washed with an ozone composition, thereby obtaining an ozone washed fabric.

Provided are a textile printing ink set including a pretreatment liquid including a cationic compound having a molecular weight per cationic valence of 150 to 220, and an ink composition including a water-insoluble dye, a dispersing agent, and water, wherein the dispersing agent is at least one selected from the group consisting of a urethane resin, a urea resin, and a urethane-urea resin; and a textile printing method.
