The present invention relates to a composite textile article which includes at least one textile, a biopolymer layer on the textile and a textile softening agent on at least part of the biopolymer layer. The textile article may be a fiber, a yarn, a fabric or a garment. The textile softening agent may be macro-silicone, semi-micro silicone, micro-silicone or nano-silicone. The biopolymer layer may comprise a sugar-based biopolymer, an amino acid-based biopolymer, or a mixture thereof. The composite textile article may be an elastic woven fabric or denim garment.

Provided is a process for forming a composite textile article that includes a biopolymer layer. The process includes providing a textile and contacting at least part of the textile with a culture comprising biopolymer-producing microorganisms and culturing the biopolymer-producing microorganisms to obtain a biopolymer layer on the textile. A silicone softening agent is provided to at least part of the biopolymer layer to obtain a composite textile, wherein the silicone comprises macro-silicone, semi-micro silicone, micro-silicone or nano-silicone. The composite textile article may be an elastic woven fabric or an elastic denim garment.

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.

Provided is a composite fabric having a base fabric and at least one bacterial biopolymer layer. The base fabric is a woven fabric, and includes warp yarns and weft yarns. At least a first plurality of warp yarns and a first plurality of weft yarns form a base layer of the base fabric. A second plurality of warp yarns and/or a second plurality of weft yarns forms an additional layer of loop portions on at least one of the sides of the base fabric. The bacterial biopolymer layer is provided at least on part of the additional layer. Further provided is a process for the production of the composite fabric and a clothing article formed of the composite fabric.

Described is a method for decoloring of a textile material, the method includes the steps of: providing a textile material; providing an alkaline solution containing one or more anionic polyelectrolytes; treating the textile material in the alkaline solution during a treatment period; and recovering at least some of the textile material from the alkaline solution.

An ink jet textile printing penetrant includes a water-soluble organic solvent; a surfactant; and one type or two or more types selected from the group consisting of a chelating agent and an aromatic compound.

A method is disclosed for producing denim-effect garments by the following steps: 1) printing a reactive dye ink onto a PET film to form a pattern thereby obtaining a transfer printed PET film; 2) transfer printing a base pulp-treated fabric by attaching the transfer printed PET film thereby obtaining a denim-effect fabric; 3) cutting, sewing, washing to soften, and drying the denim-effect fabric and thereby obtaining a denim-effect garment. The method has the advantages of simple production, being environmentally friendly, having high efficiency, and being suitable for flexible fabrics, and the produced denim-effect garment of the invention has the advantages of having a good color fastness to rubbing, washing resistance, and having a diversity of patterns, and are suitable for large-scale production and application.
