METHOD OF PROCESSING WOOL FIBERS Russian patent published in 2013 - IPC D01C3/00 D06M13/144

Abstract RU 2490377 C2

FIELD: textiles, paper.

SUBSTANCE: method includes sequential washing of fibers with aqueous solution of cleansing agents, with the intermediate wringing and the final washing with an aqueous solution containing 2-15 wt % PVA, drying followed by carding or combing.

EFFECT: invention enables to increase the micro-relief of the fiber surface by increasing the volume of the cleansed pores, to increase tensile strength and elongation, to reduce unevenness on tensile strength and significantly reduce the amount of waste generated in the process of carding and combing.
