An embodiment herein provides a process for dyeing of textile materials 108 with supercritical fluid. One or more dye materials 102 along with additives (if required) are mixed with at least one suitable solvent 104 to obtain one or more dye solutions 106. A textile material 108 is pre-treated with the one or more dye solutions 106 to obtain a dye coated textile material 110. The dye-coated textile material 110 is exposed to the supercritical fluid 112 in a supercritical fluid dyeing vessel at controlled pressure and temperature. The supercritical fluid 112 solubilizes and diffuses the one or more dye materials 102 inside the surface, pores and capillaries of the textile material 108. The supercritical fluid vessel is then depressurized below supercritical condition to entrap the one or more dye materials 102 in the textile material 108 to obtain a supercritical fluid dyed textile material 114.

A dispersible wet wipe includes a layer of cellulosic fibers. In one embodiment, a first binder is applied in a coating comprising randomly distributed deposits of the binder. A second binder is applied in an intermittent pattern on the surface to define first regions on the surface that include first binder but no second binder and to define second regions on the surface that include both first binder and second binder. The first and second binders can have the same chemical composition. In a second embodiment, a first binder is applied to a web surface in a first pattern, and, after applying the first binder, a second binder is applied to the web surface in a second pattern that is different than the first pattern. In a third embodiment, a binder is applied to a web surface in a pattern, the pattern having first regions and second regions, wherein the add-on level of the binder in the first regions is lower than the add-on level of the binder in the second regions.

The present invention provides a substrate having a unidirectional water transport property, the substrate comprised of a fluid permeable structure and including: an inner side surface; and an outer side surface having a higher absorbent capacity than the inner side surface, wherein the inner side surface has a hydrophobic surface layer extending continuously over at least one section thereof, the hydrophobic surface layer having a predetermined thickness which, in use, produces a substantial hydrophobic property to contacting water, whilst allowing for water contacting the inner side surface of the substrate to wick through the hydrophobic surface layer into the substrate; and wherein the substrate is respectively comprised of hydrophobic channels and hydrophilic channels which respectively extend between the inner side surface and the outer side surface.

To provide a method of producing a processed cloth capable of forming various concave-convex patterns on a cloth material in a simple manner. A method of producing a processed cloth comprising the steps of: preparing a cloth; printing a first sizing agent containing a foaming agent on at least a portion of the cloth material; and pressing the printed cloth with a heated metal plate to foam the foaming agent. The method of producing a processed cloth may further include a step of printing a second sizing agent containing a coloring agent on the cloth material. The method of producing the processed cloth may further include a step of sublimation transfer to the cloth material.

A dye fixing section in a foam indigo dyeing machine for dyeing traveling sheets of textile yarn. The dye fixing section receives traveling sheets of yarn to which indigo dye in leuco form has been applied and penetrated partially through the yarn. Oxygen is applied to the substrate to set the dye at the level of penetration achieved as it enters the dye fixing section, to produce yarns in the sheet with outer dyed rings and undyed cores.

Processes are disclosed which substantially eliminate the formation of oxidized indigo dye before and during dye application onto a natural fiber yarn or fabric while allowing the leuco-indigo dye molecule to diffuse fully into the natural fibers of the yarn where it can fix to the fibers prior to oxidation (i.e., exposure of the leuco-dyed yarns to oxygen). Indigo dyed textile products (e.g., dyed cotton yarns that may be twill woven to form a denim fabric) exhibit exceptionally high colorfastness as determined by the AATCC Crock Test.

A dyeing machine comprising at least one dyeing module in which a first squeezing device for a textile support, a first treatment tank, a central tank, a second treatment tank and a second squeezing device are located in sequence is described. The dyeing machine also includes a hydraulic system for feeding, circulating and alternately adjusting the levels of process fluids in the tanks. The tanks are preferably enclosed in a hermetically sealed upper covering shell. The two treatment tanks have the same shape, the same dimension and capacity characteristics, and are symmetrical with respect to a plane of symmetry lying in the central tank and arranged perpendicularly with respect to the direction of advance of the textile support. The dyeing machine is provided with means for moving the textile support, configured to advance the textile support alternately in both directions, i.e. either from the first squeezing device to the second squeezing device, sequentially through the tanks, or from the second squeezing device to the first squeezing device, again sequentially through the tanks.
