A method for localized or diffused decolorization of colored fabrics and garments by applying an accelerating substance comprising quaternary ammonium salts and subsequently treating with ozone.

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 fabric print medium containing a fabric base substrate and a primer layer composition applied to the fabric base substrate. Said primer layer composition includes at least three types of polymeric particles, at least two different fire retardant agents and a water-soluble high-valence metal complex. Also disclosed are the method for making such fabric print medium and the method for producing printed images using said material.

Described herein are apparatuses and methods for dyeing garments. An exemplary apparatus comprises a dye injection system configured to dispense concentrated liquid dye; a dyeing machine comprising a dyeing chamber configured for dyeing at least one garment in a dyebath; and a controller in communication with the dye injection system and the dyeing machine, wherein the controller is configured: to receive at least one garment parameter corresponding to the at least one garment; based at least in part on the at least one received garment parameter, cause the dye injection system to dispense a volume of concentrated liquid dye containing an amount of dyestuff that can be substantially absorbed by the at least one garment; and cause the dyeing machine to execute a dye cycle such that substantially all of the dyestuff in the dispensed concentrated liquid dye is absorbed by the at least one garment within the dyeing chamber.

A fabric treatment composition for preparing a fabric substrate for printing is described. The fabric treatment composition comprises at least one fibre-bonding agent, at least one hydrophobicity agent and at least 50 weight % water. A method is also described comprising applying, to at least an area of a fabric substrate, a fabric treatment composition to form a coating, wherein the fabric treatment composition comprises at least one fibre-bonding agent, at least one hydrophobicity agent and a carrier liquid; and printing at least one ink composition onto the coating. A printable fabric medium is also described comprising a fabric substrate; and a coating formed on at least one side of at least an area of the substrate.

A printable fabric medium can include a fabric substrate and a polymeric particle blend including polysiloxane particles and polyolefin release particles pre-treated on the fabric substrate. A weight ratio of the polysiloxane particles to polyolefin release particles can be from 1:5 to 4:1, for example.

An aqueous ink comprising a dispersion of a capsule composed of a polymeric shell surrounding a core, the core comprises one or more chemical reactants capable of forming a reaction product upon application of heat and/or radiation, the shell is stabilized by cationic dispersing groups and a colorant stabilised by cationic dispersing groups.

Disclosed is an environmentally friendly method that enables the pre-treatment and dyeing processes applied to cellulosic products used in the production of textile products such as towels, bathrobes to be carried out in a single bath with natural, biological preparations.
