The present invention relates to a method of dyeing using a salt mixture as an electrolyte with 0.5 to 5.00 GPL of sodium chloride or sodium sulphate and alkali agents I and II to exhaust and fix a dyestuff to a cellulose material in a reactive dyeing. In the method the cellulose fiber is treated with (i) the salt mixture with sodium chloride or sodium sulphate specifically, putting the pre-treated fiber maintained at a pH between 3 and above and an (MLR) maintained between 1:20 and 1:3 at a temperature between 20? C. and above and exhausted for between 15 minutes and above, (ii) the alkali agent I with a pH between 9.5 and above at a temperature between 30? C. and above and stained for between 20 minutes and above (iii) the alkali agent II with a pH between 10.5 and above at a temperature between 30? C. and above and stained for 40 minutes and above.

The present invention generally relates to a method for changing the color of a textile material to obtain a vintage and/or worn appearance comprising the steps of contacting the fabric textile material with a nitrate salt, activating the nitrate salt by the addition of an acid catalyst until the desired color change is achieved.

The present invention relates to a method for reducing or preventing the decomposition of a composition Z comprising Z1 a salt of dithionous acid in an amount ranging from 50 to 100 wt % and optionally Z2 an additive selected from the group consisting of alkali metal carbonate, alkaline earth metal carbonate, alkali metal or alkaline earth metal tripolyphosphate (Na.sub.5P.sub.3O.sub.10), alkali metal or alkaline earth metal sulfite, disulfite or sulfate, dextrose and complexing agents in a combined amount ranging from 0.0001 to 40 wt %, which comprises contacting the components Z1 and optionally Z2 in the solid and/or dry or solvent-dissolved or -suspended state with at least one of the following compounds V in the solid and/or dry or solvent-dissolved or -suspended state, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or of magnesium, (b) sodium tetrahydroborate (NaBH.sub.4), (c) anhydrous copper(II) sulfate (Cu(SO.sub.4)), phosphorus pentoxide and (d) basic amino acids arginine, lysine, histidine, wherein the solvent for Z1, optionally Z2 and V is practically water-free.

Described herein are compositions useful for infusing color into nonwoven polyester containing product and methods to do so. Such compositions and methods comprise use of a color infusion composition comprising an antimigrant polymer; pigment; ammonium polyphosphate; and an anionic surfactant comprising phosphate. In certain embodiments, thermoplastic polymer having a glass transition temperature (Tg) of 93.0 C. or less is used to enhance color infusion.
