METHOD AND DEVICE FOR IMPACT-WAVE PROCESSING OF FIBROUS MATERIALS Russian patent published in 2020 - IPC D01G21/00 

FIELD: textile.

SUBSTANCE: invention relates to textile industry, namely to devices and methods for primary treatment of fibrous materials and can be used in preparatory shops of spinning mills for preparation of industrial fibres of flax, hemp, jute. Device for impact-wave processing of fibrous raw material includes generator (2) of electro-pulsed discharges in liquid, bearing frame (21), device for transportation of fibrous material, at least one cylindrical shock-wave tank (10) with underwater discharge electrode (7) with high-potential (8) and low-potential (9) parts, elastic membrane (18) on end part of cylindrical housing (13) of shock-wave tank (10), vessel for water-and-raw mixture and control unit (1). Each of shock-wave tanks (10) is equipped with an additional elastic membrane, which is installed on the opposite end part of the cylindrical housing of impact-wave tank (10) opposite to the first elastic membrane (18). Vessel for water-raw material mixture is made in the form of two pipelines (15) and (16) with openings (20), which are arranged perpendicular to axes of cylindrical housings of impact-wave tanks and are conjugated with external surface of discharge electrode of elastic membrane. Also disclosed is a method for impact-wave processing of fibrous raw material. Creation of additional flow of water-raw material mixture parallel and opposite to the first flow with impact-wave action on both opposite sections of flows simultaneously by one and the same electric pulse discharge, which increases efficiency. operation at simultaneous reduction of power consumption of treatment and increases efficiency and quality of raw material treatment.

EFFECT: obtained fibrous materials can be used not only in high-quality mixed yarn and non-woven materials, but also as component (reinforcing) composite polymer materials and cellulose base in medical products.
