Description:
Replacement of waterglass as a hydrogen peroxide stabilizer in a bleaching bath when used in the textile industry by aspartic acid derivatives. A similar research was carried out at the faculty around 1990, when stabilizers based on the homopolymer of maleic anhydride were tested very successfully in the flax industry during bleaching of flax yarn. The replacement of water glass has significantly improved the quality of flax yarns and fabrics. The proposed case would be polycarboxylates based on aspartic acid derivatives. Water glass in the bleaching process forms deposits of silicates (also calcium silicates) on the bleached material and the machinery used. The choice of a suitable aspartic acid derivative would ensure the sequestration of calcium and magnesium into the water-soluble complexes and at the same time stabilize the hydrogen peroxide in the bleach bath. The project assumes the preparation of functional samples, their testing both in the laboratory and in the operating conditions of the selected company. In the form of subcontracting tests for biochemical degradability. Finally, patent protection of a provably effective formulation.
