摘要:
Dyed raw cellulose can be bleached in a bleaching and after-treatment bath containing, in addition to usual stabilizers, cationic-monomeric and/or polymeric compounds and, if desired, nonionic surfactants. Bleaching is carried out with the aid of aqueous-hydrogen peroxide. The stabilizers that can be used and the cationic compounds are defined in the specification. Nonionic tensides, if their co-use is desired, are those of the class polyglycolethers.

The present invention relates to novel liquid formulations for the controlled and sustained release of insecticidally active compounds by means of a heat source and the water-based pre-solutions required for preparing these formulations.
摘要:
Polyamide-containing fibre materials can be given an anti-stain finish by treating them with a sulpho-containing aromatic formaldehyde condensation product in combination with polyacrylic acid, the treatment with the two components being carried out in any desired order or simultaneously.
