METHOD OF MANUFACTURING PAINTED CELLULOSE ACETATE FIBERS Russian patent published in 2009 - IPC D06P3/44 D01F2/16 

FIELD: textile fabrics, paper.

SUBSTANCE: invention relates to field of dyeing-finishing manufacturing and can be used at colour execution of products from modified cellulose acetate (CA) fibers. It is described method of manufacturing of painted cellulose acetate fibers, consisting in that spinning solution of cellulose acetate is introduced 8-oxyquinoline in amount 0.5-5.0% from mass of polymer and from it is formed fiber. Fiber is impregnated according to continuous method by water solution of colloidal solution at pH 4.5-7.0, temperature not higher than 20°C and liquor ratio 8-10 during 1-5 minutes, it is wringed out up to additional weight 85-90%, it is steamed at 102-103°C during 2-8 minutes, washed and dried. There are used water solutions of dia-dispersoid solutions of concentration 20-60 g/l at 20-33% content of dia-dispersoids in vendible product.

EFFECT: reduction of power inputs and receiving on CA fibers of even, deep, bright and beautiful by colour of colouring of different colors, allowing high durability against physicochemical influence.
