    摘要: A device and a method of flattening recycled carbon fiber material are provided. A main body is provided with two flat plates at an upper and a lower positions corresponding to each other and an ultrasonic unit is disposed on each of the flat plates. While in use, recycled carbon fiber material is placed at the lower flat plate and then at least one ultrasonic probe of the ultrasonic unit is driven to work and vibrate the recycled carbon fiber material into a flat and thin state. After the flattened recycled carbon fiber material being pressurized to form products required, the product has flat and smooth surfaces with special textures. A thickness of the product can be controlled and the product can be thinned according to users' needs, without surface treatment such as grinding, polishing, etc. Thereby production cost is reduced and yield rate of the products is improved.

    摘要: The invention relates to the textile industry, and specifically to methods for processing bast-fiber materials, for instance the fiber of flax, hemp, jute, nettle, kenaf, and others. The technical result which the present invention aims to achieve consists in: enhancing the quality of a cottonized fiber, when processing bast-fiber materials, by means of high-voltage electric pulse discharges following preliminary biochemical and final minimal mechanical processing; and in enhancing the physical/mechanical and spinning properties thereof, which, overall, allows for an optimized, efficient production process. Said technical result is achieved in that a bast-fiber material processing method includes a technological sequence of processes involving feeding raw material into a bale breaker, which is provided with a decompactor, and into a dosing system, processing using high-voltage electric pulse discharges, rinsing with emulsifying reagents, washing and press-drying in a drum-type installation, decompacting, final drying and light decompacting; the raw material is biochemically treated prior to being fed into high-voltage electric pulse discharge chambers.
