Definitions

• a process for reducing or preventing discoloration of a textile material in a wash bath comprising
• the wash washing one or more dyed textile materials (herein defined as "the wash") that contain free dye or liberatable dye (i.e dye that can be washed out of the material) in the presence of a dye scavenger capable of taking up any free dye or any dye that is liberated in the wash, the scavenger comprising a substrate to which a polymeric material, (hereinafter referred to as the polymeric material) selected from any one of Products A to D, is fixed where Products A to D are as follows:
• the dye scavenger may be dyed or undyed. Preferably the scavenger is undyed.
• the polymeric material of the dye scavenger has a molecular weight of over 4000, more preferably over 5000.
• Product A is known, and is described for example in British Published Patent Application No 2 142 642, US Patent 4 764 585 and US Patent 4 410 652, and may be prepared by methods described in said patents,the contents of which are incorporated herein by reference.
• the amine, in free base or salt form is reacted with the other starting material in the absence of water at elevated temperatures optionally in the presence of a non-aqueous solvent.
• the reaction is carried out in the absence of solvent at a temperature of 140-160°C, and for most combinations of reagents, ammonia is evolved.
• the reagents are preferably reacted in a molar ratio of 0.1 to 1 mole of cyanamide, DCDA, guanidine or biguanide per mole of reactive -NH- or -NH2 group, and when DCDA is reacted with a polyalkylene polyamine, the molar ratio of the reactants is more preferably from 2:1 to 1:2, particularly about 1:1.
• the reactants are reacted in the presence of a catalyst selected from metals, metal salts and heterocyclic nitrogen-containing compounds (defined as catalyst K in USP 4 764 585).
• the Products A are near-colourless viscous liquids or solids which are basic in character, water-soluble either in the free base or salt form, and contain reative hydrogen atoms bonded to nitrogen.
• Up to 50 mole % preferably up to 20 mole % of the DCDA or other reagent to be reacted with the amine may be replaced by a dicarboxylic acid or a mono- or di-ester thereof.
• Suitable acids include adipic acid, oxalic acid and terephthalic acid, for example in the form of their dimethyl esters.
• Particularly preferred Products A are the reaction products of DCDA with diethylenetriamine or triethylenetetramine, preferably in the presence of a catalyst selected from metals, metal salts and heterocyclic nitrogen containing compounds (especially zinc chloride) defined as catalyst K in USP 4 764 585.

• the polymeric material is Product A, C, or D.
• the polymeric material of the scavenger is Product A or Product C′; where Product C′ is a synergistic mixture containing as active ingredient a textile auxiliary (T) and the polymeric compound (P) in which T is the product of a 2-step reaction comprising the steps of
• P is a water soluble homopolymer of a mono-or di-allylamine, or a water soluble copolymer comprising (preferably consisting of) mono-, di- or tri-allylamine units.
• the synergistic mixture may also contain 3) the reaction product of epichlorohydrin or a precursor thereof with a polyalkylene polyamine.
• polymeric Product is Product A (especially Product of Example 1 as described in USP 4 764 585).
• the amount of polymeric material to substrate of scavenger is to 20 %, more preferably 2 to 6 %, by weight of substrate.
• the scavenger can be in any form.
• the polymeric material can be applied to the whole substrate or to just a surface.
• Preferred substrates including fabrics, garments, films, non-woven material or paper.
• the substrates can be natural or synthetic, preferably undyed cotton, undyed regenerated cellulose or undyed natural or synthetic polyamide.
• the substrates can be treated with any one of Products A to D by known methods, for example by immersion, padding, spraying, printing, exhaustion.
• the amount used is preferably from 2 to 200 g/l, more preferably 10 to 80 g/l (based on the activates of components A to D) preferably in a goods to liquor ratio of 1:1 to 1:30.
• the scavenger that is so produced can be used in standard washing procedures, merely by being added to the wash.
• the scavenger takes up any free or liberated dyestuff, in particular anionic dyestuff, free in the bath. In this way, the scavenger assists in preventing staining of the washing by free dye being taken up undesirably on other pieces in the wash.
• the scavenger is optimally effective with dyeings, preferably of not more than 1/1 standard depth, especially in light shades.
• the amount of scavenger should be sufficient to prevent as reduce staining and/or discoloration. This amount will vary depending on the total amount of wash and also on the properties of wash that contains free or liberatable dye.
• the amount of scavenger to the wash is preferably 5 to 80 g to 1 kg of the wash; more preferably 10 to 30 g to 1 kg of wash.
• the substrate of scavenger is a textile material.
• the textile material (hereinafter referred to as the "scavenger") is then added to a household coloured wash made up of cotton textile fabric dyed with C.I. Reactive Violet 23 and undyed cotton textile fabric.
• the weight of the wash is 3 kg and the wash to bath ratio is 1:4.
• the washing powder used was "0mo", a commercially available product, for a 60°C wash and was used in an amount of 6 g/l.
• the amount (by weight) of scavenger to washing is about 1 that is to say 30 g of scavenger is used.
• the wash and scavenger is then washed in a Bauknecht washing machine, a commercially available household machine, at 60 °C and is then dried.
• Example 1 is repeated, using instead of the C.I. Reactive Violet 23, C.I. Direct Blue 251.
• the resulting scavenger is soiled with free dye.
• Example 1 is repeated using the following wash. 60-70 % cotton dyed with C.I. Direct Blue 251 ; 10 % nylon dyed with the dye of Example 1 of D.O.S. 2,400,654 ; 15 % Dacron T56, dyed with C.I. Disperse Yellow 23 ; and 5 % Orlon dyed with C.I. Basic Blue 45.
• the wash is then washed with the scavenger at 60°C.
• the scavenger picks up the free dye available (primarily of C.I. Direct Blue 251) whereas the fabrics of the wash retain their clear colours.
