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.

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.

An electrolytic dye reduction method comprises preparing a catholyte by dispersing a dye in a leucodye comprising electrolyte. In a preferred method the leucodye like leucoindigo is the sole dispersing aid.

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.

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.

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.
