FILAMENTS CONTAINING MICROFIBRILLARY CELLULOSE, FIBROUS NON-WOVEN FABRICS AND METHOD OF THEIR PRODUCTION Russian patent published in 2017 - IPC D01D1/02 

FIELD: textile, paper.

SUBSTANCE: cellulose textile filament obtained from fibers of the microfibrillary cellulose and thickening agent, as well as precursor spinning solutions for spinning of such filaments, non-woven fabrics obtained from such cellulose textile filaments, and the method of production of such filaments and non-woven fabrics containing such filaments are expressed in this document. One of the advantages of these filaments is the eco-sensitive method, by which they are produced, because the water-based spinning solution is used, which does not require any chemical solvents in contrast to other methods, such as applicable ones during production of Lyocell fibers. Additionally, the method does not contain any stages of washing-off or extraction, as well as it does apply the source of cellulose fibers, which is widely used and renewable.

EFFECT: document reveals the properties of the filament and the methods of production of such filaments, as well as describes advantages of such filaments.
