A textile substrate is patterned by the selective application of various dyes to the substrate surface in a way that provides desirable, visually apparent enhancements in the area of pattern detail, definition, and color range, through the use of a novel patterning system, including the application of various chemical agents, that makes such enhancements possible. In one embodiment, the patterning system described herein is capable of producing pile-faced textile substrates, useful as floor coverings, that exhibit a unique combination of desirable pattern attributes that have been identified and measured using novel techniques specifically developed for these substrates and pattern attributes.

Patterned textile product

A dyed substrate having at least one dyed surface. At least one dye solution is disposed across at least a portion of the surface in combination with a migration promoting composition and/or a migration limiting composition. The migration promoting composition and/or migration limiting composition adjusts the migration of at least a portion of the dye solution across the substrate in a controlled manner. Dye migration may be arrested by the application of RF (radio frequency) energy as a step in dye fixation. A process for forming the dyed substrate is also provided.

Selective application of chemical agents in the pattern dyeing of textiles

A textile substrate is provided which is coated with a film comprising iron (III) oxide hydroxide and aluminum oxide hydroxide. This film or coating is formed by contacting the textile substrate with an aqueous solution comprising ferrous or ferric salts and aluminum salts. The iron (II), iron (III), and aluminum ions are hydrolyzed and the iron (II) ions are also oxidized under controlled conditions. These hydrolyzed species then, it is believed, coprecipitate or copolymerized to on the textile surface to form a smooth, coherent, substantially amorphous iron (III) oxide/aluminum oxide hydroxide film or coating on the surface of the substrate without forming an insoluble iron (III) or aluminum hydroxide precipitate in the solution. This is accomplished by controlling the reaction conditions such that the rates of adsorption onto the substrate surface of both iron (III) and aluminum oxide hydroxides are greater than the rates of formation of said same oxide hydroxide particles. The resultant coating is substantially amorphous with extremely limited crystalline formation. The obtained substrate has very good color fastness, bacteriostatic, and virus removing properties and can be utilized as an inexpensive and effective water filtration article.

Textile surface coatings of iron oxide and aluminum oxide

A process is disclosed for using thickening agents with specific properties in connection with the automated pixel-wise patterning of textile substrates using liquid dyes.
