METHOD OF PRODUCTION OF FLAX COTTON-WOOL Russian patent published in 2013 - IPC D04H1/02 

FIELD: textiles, paper.

SUBSTANCE: method of production of flax cotton-wool comprises preparing fiber, its mechanical treatment, bleaching using chemical solution, rinsing, spinning and drying. In preparing the fiber, the ribbon is formed from it, which is treated with the chemical solution, followed by rinsing, spinning and drying. The dry bleached ribbon is subjected to mechanical treatment by alternating bending deformation, bilateral sliding bending with entanglement of the ribbon end parts and the subsequent purification of short-stapled fiber formed by mechanical treatment from non-fibrous impurities.

EFFECT: reduction of content of foreign impurities, improving the quality of flax cotton-wool and reduction of fibrous losses.
