  • Method for the preparation of borate-containing, dispersible, water-soluble polygalactomannans and polygalactomannan derivatives
    Patent number: 4745184
    Abstract: Method for preparation of dispersible, water-soluble polygalactomannans and polyglactomannan derivatives by crosslinking with borate ions, in which the polygalactomannan-containing endosperm of legumes is allowed to soak in an aqueous alkaline solution of a material containing borate ions in which the concentration of the borate ions, expressed as borax, is between 0.001 and 0.09 wt. % and the hydroxyl ion concentration, expressed as NaOH, is between 0.2 and 10 wt. % of the polygalactomannan and after taking up the solution, the cell structure of the splits is mechanically destroyed using high shear forces in a flaking, crushing or extruder process and then the product of the process is dried and ground in known fashion.
    Type: Grant

  • Sizing agent and process for the manufacture thereof
    Patent number: 4368324
    Abstract: A sizing agent for yarns made of cotton, regenerated cellulose and synthetic fibers and their mixture. The sizing agent substantially comprises a hydroxyalkylated polysaccharide from the seed of Cassia occidentalis. The polysaccharide has a viscosity of from 40 to 10,000 mPas (10% aqueous solution, 80.degree. C., Brookfield RVT) and a substitution degree of from 0.05 to 1.0.
