A process and composition is provided for preparing substrates with both visual and thermal camouflage. The substrate is metallized through a deposition process and polished or calendered to smooth the metal layer and lower the infrared emissivity of the layer deposited onto the substrate. The metallized substrate is then visually decorated by a tarnish and/or dying process that minimally impacts the infrared emissivity of the metallized substrate.

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.

Silkworm silk, has been processed into a variety of new material formats including, hydrogels, ultrathin films, thick films, conformal coatings, 3D porous or solid matrices, fibers and many related material formats. Silk is processed in an all water-based, room temperature, neutral pH environment, is mechanically stable, edible, and biocompatible. Given the favorable material properties, the use of silk-based inks have been used in a variety of controlled chemical and biological material fabrication on the micro- and nano-scale. Tuning of the properties of silk-based inks has led to the utilization of more diverse printing techniques and has expanded the scale and function of the printed substrates.

A treatment solution composition for ink jet textile printing contains one or more selected from the group consisting of a glycol solvent with a molecular weight of 100 or less and a sugar with a molecular weight of 400 or less, water, and an alkaline agent.

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.

A sprayable and hygroscopic ink for a digital printing process on a fabric includes 3.0 parts by weight to 6.0 parts by weight of a colorant, 0.5 parts by weight to 2.0 parts by weight of a hygroscopic agent, 0.5 parts by weight to 1.0 part by weight of a surfactant, and a balance of a solvent, in which a pH value of the hygroscopic agent is between 6.0 and 8.5 at 25° C., and a particle diameter D90 of the sprayable and hygroscopic ink is between 180 nm and 220 nm.

A biopolymer composition can be formed based, at least in part, on a recombinantly expressed protein, expressed from a DNA coding sequence of a source protein, and the recombinantly expressed protein can optionally comprise one or more tags that enhance the crosslinking capacity of the protein. It was determined that such biopolymer composition can be suitable for use to obtain, for example, a biodegradable textile that exhibits a functional characteristic associated with the recombinantly expressed protein.
