Cellulose-based material suitable for low-salt dyeing and printing providing high dyestuff yields and color fastness and for printing using an inkjet method and wet transfer printing

摘要

A method for the production of a cellulose fibre - or fabric by spinning or extrusion of a cellulose carbamate hold strength spinning - or extrusion solution and by the usual further processing to fiber - or sheetlike structures characterized in that the carbamate groups in the cellulose fiber - or planar structure according to the spinning - or extrusion process are hydrolyzed to such an extent that, in the cellulose fiber - or sheetlike structures 0,02 to remain 0,85 carbamate groups per anhydroglucose unit, wherein the cellulose fibre - or sheetlike structures for the hydrolysis in an alkaline bath is washed.
