FLAME-RESISTANT MOULDED CELLULOSE BODIES PRODUCED ACCORDING TO DIRECT DISSOLVING METHOD Russian patent published in 2018 - IPC D01F1/07 D01F2/02 C08L1/02 C08L61/28 

FIELD: pulp industry.

SUBSTANCE: invention relates to the field of permanently treated cellulose moulded articles, in particular to shaped lyocell articles – fibres, yarns, directly moulded nonwoven materials, films or foams that have fire retardant properties. Said fibres and filaments can be further processed as textiles into yarns, wovens, knitted fabrics, and nonwovens. Said moulded articles are produced from solutions of cellulose and melamine cyanurate or cellulose and crosslinked or partially crosslinked melamine resin particles in an organic solvent. Melamine cyanurate or melamine resin particles provide the moulded cellulose bodies with flame-retardant properties. Molded cellulose articles made of cellulose and melamine cyanurate or melamine resin particles can further contain flame retardants, in particular flame retardants which act synergestically, in a particulate form. Obtained textile fibres and nonwoven materials have a soft touch and can be processed or finished as filaments or yarns on conventional textile machines.

EFFECT: invention provides a flame-retardant, moulded textile article made of cellulose, the fire resistance of which remains constant during use.
