Definitions
- the invention relates to a gentle method for bleaching textiles, in particular colored and delicates with preparations containing hydrogen peroxide, for the production of which the use of heavy metal and / or chloride ions has been dispensed with.
- liquid laundry pretreatment agents are on the market which are applied to the stains in concentrated form before the laundry. These are usually more or less dilute hydrogen peroxide solutions that contain small amounts of anionic or nonionic surfactants and, if necessary, thickeners (e.g. electrolyte salts), colorants and fragrances.
- anionic or nonionic surfactants e.g. anionic or nonionic surfactants
- thickeners e.g. electrolyte salts
- the object of the invention was therefore to provide a process for the treatment of textile fabrics, preferably textiles, but also fabrics and knitted fabrics, which reliably avoids the problems mentioned in connection with the use of aqueous hydrogen peroxide solutions.
- the invention relates to a process for the gentle bleaching of textile fabrics by bringing them into contact with aqueous preparations containing hydrogen peroxide, which is characterized in that the agents are free of heavy metal and / or chloride ions.
- a particular embodiment of the invention relates to a method in which red-colored preparations are used instead of the commercially available blue-colored bleaching agents.
- pitting due to chlorine formation can be reduced further by adding nitrogen, phosphorus or iodine-containing inhibitors to the bleaching agents, which either capture and chelate ions in the sense of a sequestering agent or the oxidation of the iodide to hypochlorite or chlorine prevent.
- the first group includes the substances of the formula (I),
- n stands for numbers from 1 to 3.
- Typical examples are nitrilotriacetic acid or nitrilotripropionic acid.
- EDTA ethylenediaminetetraacetic acid
- Further suitable inhibitors are phosphonic acids, amine oxide phosphonic acids or their alkali salts such as, for example, acetophosphonic acid or the amine oxide phosphonic acids, which are commercially available from Bozetto / IT under the brand Sequion®.
- Alkali periodates, in particular sodium periodate, can be used as inhibitors of the second group. The amount used is in the range from 0.01 to 1, preferably 0.05 to 0.1% by weight, based on the formulations.
- the bleaching agents to be used in the process according to the invention usually contain hydrogen peroxide in amounts of 1 to 10, preferably 5 to 8 and in particular 6 to 7% by weight.
- the calculation relates in each case to 100% by weight of active substance, while the use is generally in the form of 35% by weight solutions.
- surfactants which can be present in amounts of 0.1 to 10% by weight and preferably 1 to 5% by weight are fatty alcohol ether sulfates, fatty alcohol ethoxylates, oxo alcohol ethoxylates - the latter two with a conventionally broad and narrow homolog distribution - alkyl polyglucosides, fatty acid N- alkyl glucamides, amine oxides and alkyl phosphates.
- the bleaching agents can contain electrolytes.
- electrolyte salts with the demanding restrictions alkali or alkaline earth salts of mineral acids and their mixtures come into consideration, which are used as auxiliaries for the Viscosity adjustment of aqueous surfactant solutions are basically known.
- Magnesium sulfate is preferably used.
- the amount of salts used can be 0.1 to 2% by weight.
- the agents can contain lower alcohols such as ethanol or isopropyl alcohol, peroxide-stable fragrances, optical brighteners, antioxidants, dyes and pigments in a total amount of 0.01 to 0.5% by weight, based on the agents.
- the fragrances known to be peroxide-resistant include, for example, monocyclic and bicyclic mono-alcohols and their esters with acetic or propionic acid (for example isoborneal, dihydro-oil, isobornyl acetate, dihydroterpenyl acetate).
- the optical brighteners can be, for example, the potassium salt of 4,4'- bis (1,2,3-triazolyl) - (2 -) - stilbin-2,2-sulfonic acid, which is sold under the brand name Phorwite® BHC 766 or Tinopal
- CBS-X (Ciba) is sold.
- suitable antioxidants are di-tert-butylhydroxytoluene (BHT), di-tert-butylhydroxyanisole (BHA), tocopherol (vitamin E), ascorbic acid and ascorbic acid palmitate, optionally in combination with citric acid.
- BHT di-tert-butylhydroxytoluene
- BHA di-tert-butylhydroxyanisole
- vitamin E vitamin E
- ascorbic acid and ascorbic acid palmitate optionally in combination with citric acid.
- TAED can be used as a bleach activator.
- yellow Solar Yellow BG 300 (Sandoz) or preferably red Rojo Basazol® can be used as color pigments.
- the preparation is made by stirring. If necessary, the product obtained can be decanted or filtered to remove foreign bodies and / or agglomerates.
