Definitions
- the invention relates to alkali containing silica solution containing organic calcium sequestrant, to a bleaching bath formulation containing said silica solution and to a process for the alkaline hydrogen peroxide bleaching of textiles.
- Silicates are well characterised in the literature, for example "The Chemistry of Silica” by R.K. Iler (published by Wiley Interscience 1979) and they have many forms depending on the cation associated with the silicate species, the ratio of metal oxide of this cation to the silicon dioxide content of the solution, and the total solids content.
- Silicate liquors find uses as sealants adhesives, protective coatings, binders and also stabilisation system in the hydrogen peroxide bleaching of textiles, for example cotton and polyester/cotton (see “The Encyclopedia of organic Chemistry", Kirk Othmer, 3rd Edition, Supplement Vol.3, 1979, pages 877 and 949).
- silicate containing either potassium or sodium oxide is recognised as being the best stabilising system for alkaline hydrogen peroxide bleaching of cotton and polyester/cotton (white goods), i.e. the reaction of the soluble silicate to prolong the active life of the hydrogen peroxide in the bleaching bath, the drawbacks of using silicate are well documented.
- the whiteness values have been measured on the treated cloth, after bleaching for 20 minutes at 100°C in a Werner Mathis steamer. Listed below in Table 1 are the whiteness values obtained for the various silicate additions, the measurements being determined on an Elrepho spectrophotometer.
- the blends have been prepared by adding the candidate neutralised organic acid calcium sequestrant (40% solution as its sodium salt) to the stirred alkali containing silica solution. After aeration has settled, caused by the mixing action of the stirrer, the blends are transferred to a glass sample bottle and sealed to prevent moisture escaping. The blends have been stored for up to a period of 3-months at ambient temperature. The observations recorded in Table II are on the blends after standing for one month.
- the CCPL's for the range of modified alkali containing silica solutions containing 4% of the sequestrant in the form of its sodium salt, in the ratio range 1.6 to 2.0 are given in Table IV.
