Described are methods and systems for cationizing and dyeing a natural fiber-containing textile, which uses a mono- or di-quaternized cationizing agent. The method includes a step of heating the textile to a temperature in the range of 90° C. to less than 110° C. for a period of time in the range of 1 min to 10 min to react the cationizing agent with the textile. The cationization step in the presence of heat using the halogenated cationization agent of the invention facilitates improved dyeing.

Dye baths including an aqueous solution including lignin in a range of 10% to 30% by weight of the aqueous solution are described. In addition, methods of dyeing fibers, yarns, textiles, or garments with an aqueous solution including 10% to 30% lignin by weight is disclosed. Further, methods of dyeing a fabric including preparing a first dye bath including an aqueous solution having lignin in a range of 10% to 30% by weight of the aqueous solution and passing a fabric through the first dye bath such that the fabric pics up lignin to dye the fabric is disclosed.

A method for manufacturing a dye scavenging substrate which comprises the steps of: (a) providing an absorbent substrate; (b) passing the substrate through a bath containing an alkaline solution of a dye scavenging compound selected from: (i) a N-trisubstituted ammonium-2-hydroxy-3-halopropyl compound having the general formula (I), or (ii) a salt of epoxy propyl ammonium having the general formula (II), or a combination thereof; (c) subjecting the substrate to a pressure of from about 0.04 MPa to about 0.40 MPa; (d) wrapping the substrate in a water impermeable material and rotating the substrate for a period of from about 12 hours to about 60 hours; (e) removing the water impermeable material and passing the substrate through a bath containing an acid solution; (f) subjecting the substrate to a pressure of from about 0.15 MPa to about 0.40 MPa; and (g) drying the substrate.

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.
