Abstract:
The precipitation of scale-forming materials in an aqueous system is inhibited by adding substoichiometric amounts of a precipitation inhibitor which consists of a mixture of an amino alcohol such as triethanolamine and certain phosphonic acids, such as amino tri(methylene phosphonic acid), to said system.
Abstract:
THE BLEACHING ACTION OF SOLUTIONS OF CHLOROCYANURIC ACIDS, SALTS AND COMPLEXES IS IMPROVED AND THE CORROSIVITY OF SUCH SOLUTIONS REDUCED BY THE INCLUSION THEREIN OF A TAURATE OF A SATURATED FATTY ACID.
Abstract:
Wool is rendered resistant to shrinking by contact with a solution of ((mono-trichloro,) tetra-(monopotassium dichloro,)) penta-isocyanurate or (trichloro), (monopotassium dichloro,) diisocyanurate.
Abstract:
TEXTILE FIBERS BLEACHED WITH SOLUTIONS OF CHLOROCYANURIC ACIDS, SALTS OR COMPLEXES ARE SOURED BY CONTACT WITH AN AQUEOUS ACIDIC SOLUTION CONTAINING HYDROXY ETHYLIDENE DIPHOSPHONIC ACID, SODIUM HEXAMETAPHOSPHATE, ETHYLENE DIAMINE TETRAACETIC ACID, NITRILOTRIACETIC ACID, ALKALI METAL SALTS OF THE FOREGOING ACIDS OR MIXTURES OF THESE COMPOUNDS AS WELL AS THE SULFITE SALTS CONVENTIONALLY UTILIZED IN SOURING SOLUTIONS. THE PROCESS PROVIDES FIBERS CHARACTERIZED BY IMPROVED APPEARANCE AND REDUCED HEAT SENSITIVITY.
Abstract:
A cyanide free electrolyte for the electrodeposition of metals comprises an aqueous solution of (a) a metal ion, (b) a cyanidine compound and optionally, (c) a phosphonic acid compound.
Abstract:
The precipitation of scale-forming materials in an aqueous system is inhibited by adding substoichiometric amounts of an amino alcohol such as triethanolamine to said system.
Abstract:
Textile fibers which have been desized and are about to be bleached are scoured with an alkaline caustic solution containing a surfactant and a synergistic inhibiting agent such as a mixture of amino tri(methylene phosphonic acid) and triethanolamine. This process provides fibers with a substantially reduced impurity level and an end product which is substantially more conducive to subsequent bleaching and dyeing processes.
Abstract:
Textile fibers which have been desized and are about to be bleached are scoured with a boiling alkaline caustic solution containing a surfactant and a solubilizing agent such as amino tri(methylene phosphonic acid). This process provides fibers with a substantially reduced impurity level and an end product which is substantially more conducive to a subsequent dyeing process.
