METHOD OF SHOCK WAVE TREATMENT OF FIBROUS RAW MATERIAL Russian patent published in 2013 - IPC D01G11/04 D02G3/00 

FIELD: textiles, paper.

SUBSTANCE: method of shock-wave treatment of raw materials includes preliminary mechanical treatment containing raw material adhesive, placement of successive batches of raw material into the aquatic environment, carrying out a shock-wave treatment of raw material with electropulse exposure in a mixture of "water-raw material" for garnetting and separation of fibers of raw material, dehydration and carrying out the final mechanical treatment. During the shock-wave treatment of portion the energy of electric pulse exposure is increased. The electric pulse exposure on subsequent portion of materials is carried out in an aquatic environment with dielectric adhesive fractions from the previous portion. The energy increase of electric pulse exposure is agreed in time with the stages of garnetting and separation of fibers of the raw material.

EFFECT: improvement of quality of garnetting the fabric and separation of fibers while simultaneous reduction of energy intensity of the treatment process, increase in its coefficient of efficiency and productivity of the process in production of a quality recycled fiber.
