Process for washing, bleaching and cleaning of solid materials, mainly textiles, as well as compositions for the preparation of the process.

摘要

A method of washing soiled textiles, wherein the soiled textiles are immersed in an aqueous liquor which contains at least one compound inhibiting alkaline earth metal ion precipitation on said soiled articles comprising using finely-dispersed, water-insoluble silicate compounds having a calcium-binding power of at least 50 mg CaO/gm of anhydrous active substance and having the formula, combined water not shown (M2/nO)x ? Me2O3 ? (SiO2)y where M is a gallon of the valence n, exchangeable with calcium, x is a number of from 0.7 to 1.5, Me 18 a member selected from aluminum and boron and y 18 a number of from 0.8 to 6, as said compound inhibiting alkaline earth metal ion precipitation; as well as washing compositions containing said silicate compounds.
