FORMALDEHYDE-FREE COMPOSITION FOR FINAL TRIMMING OF CELLULOSE DECOMPOSING TEXTILE MATERIALS Russian patent published in 2009 - IPC D06M15/267 D06M11/155 D06M13/46 D06M11/64 

FIELD: textile, cotton.

SUBSTANCE: this invention refers to the chemical technologies of the textile materials in particular, to the production of the formaldehyde-free compositions for the final trimming of the cellulose decomposing textile materials. The composition includes in g/l: 80-120 of othexide BPh-diglycol ether 1,3 - dimethyl- 4,5- dihydroxyethylene of the carbamide, 5-8 catalyst agent for the resinification including magnesium chlorides - the natural bischofite solution extracted by the underground dissolution of the chlorine magnesium salts, 2-4 of aluminium nitrate, 2-5 cloridealkyldimethylbenzyl ammonium and water up to 1 litre.

EFFECT: this invention allows to make the cellulose decomposing textile materials sanforised, decrease the tendency to be crumpled, decreases the strength losses, reduce power inputs due to the exclusion of the thermal treatment operation and reduction of the drying temperature (the final section 130°C), and to improve the stability of the composition and environmental security.
