Abstract: Electro-osmotic (or electrokinetic) transport is used to efficiently force a solution (or water) through the interior of the fibers or yarns of textile materials for wet processing of textiles. The textile material is passed between electrodes that apply an electric field across the fabric. Used alone or in parallel with conventional hydraulic washing (forced convection), electro-osmotic transport greatly reduces the amount of water used in wet processing. The amount of water required to achieve a fixed level of rinsing of tint can be reduced, for example, to 1-5 lbs water per pound of fabric from an industry benchmark of 20 lbs water/lb fabric.

Abstract: The present invention relates to an environmentally safe, water-free method for color fading and for producing patterns on textile materials (1, 10) by exposure to laser radiation (7, 12) of sufficient intensity to cause photo-decomposition of the coloring agent while leaving the underlying textile material undamaged. The pre-dyed material (1, 10), such as denim, is scanned by a laser beam (19, 20) generated by a selected laser having selective output characteristics to produce uniform fading and patterns of photo-bleached marks on the textile material (1, 10). When the laser radiation is modulated at a selected frequency, the fading may take the form of stone washing (18a and 18b), echo ball washing, or acid washing techniques commonly used on denim materials. The patterns (17a and 17b) may take the form of any desired image, line, or picture in the substrate material. For mass production the textile materials may be moved under the laser by a conveyer belt or similar means.

Abstract: Deep-colored fibrous articles, such as fabrics colored in a deep black shade, having on it surfaces a film coating of a resin mixture comprising at least two resins that are mutually miscible but incompatible and in phase-separated conditions. Color-deepening effect is augmented by forming pits and/or recesses and projections on the surfaces of the film coating by using resins different in solvent-solubility and eluting the resin having a larger solubility with a solvent. The above effect is further augmented by using resins different in plasma etching resistance and subjecting the formed film coating to a low-temperature plasma etching treatment. The plasma etching is effectively conducted by placing the fibrous article within a plasma sheath, preferably contacting with an antenna electrode. The deep color can be made abrasion resistant by further depositing an abrasion resistant resinous film on the pit-formed resinous film coating without filling up the pits.
