A method for processing bast-fiber materials involving loosening a material, placing said material in an aqueous medium, hydrodynamically processing material successively in two modes: first, in a continuous mode by performing a hydrodynamic wave field action, and then in a pulsed mode by performing a shock-wave action, wherein the pressure amplitude of the positive wave phase in the continuous mode is less than the pressure amplitude of the positive wave phase in the pulsed mode, and removing the material from the aqueous medium. It is possible by the method to produce a high quality cottonine, the linear density of which is equal to or less than 0.3 Tex with the optimal energy consumption of the production process.

A process of decortication for separating the bast from the inner core of fibre plants using a disc refiner includes the steps of cutting the straw to a predetermined length; refining the straw by passing the cut straw of the predetermined length through a disc refiner with an applied energy less than about 150 kWh/t; and screening the refined straw to separate the bast fibres from the inner core.

An apparatus for processing a fibrous material batt like lint cotton to increase the moisture content of the material and to compress the batt of humidified fibers to increase the batt density. A stream of warm humid air is passed through the moving batt of fiber that is constrained between a rotatable hollow cylinder and a stationary perforated screen. The air passing through the batt of figure removes debris from the batt and carries the debris to an associated plenum. The batt is doffed off the rotatable cylinder by a roller that serves to both doff and compress the batt. A roller doffs the fiber batt from the rotatable cylinder and doffs and compresses the batt against a compression roller.

A wool card includes a rotatable Morel roller and first and second burr beaters rotatable relative to the Morel roller and relative to each other and spaced apart about the periphery of the Morel roller. The wool to be carded moves in one direction about the Morel roller and between the first burr beater and the Morel roller and then between the second burr beater and the Morel roller. The first burr beater turns at a lower speed than the second burr beater. The burr beaters have blades thereon which contact the wool to remove impurities from the wool. The number of blades on the first burr beater is less than the number of blades on the second burr beater.

The dosing method and apparatus meters predeterminate quantities of fiber flocks per unit of time by means of two feed devices arranged at the lower end of a flock chute and which form therebetween a conveying gap and an opening roll is preferably arranged beneath the feed devices. The feed devices selectively comprise either:(a) a rotatable feed roll and an oppositely situated slide; or(b) a rotatable feed roll and an oppositely situated driven or freely revolving belt; or(c) two oppositely situated revolving belts, wherein at least one of the revolving belts is driven and the other either revolves or is likewise driven; or(d) a driven revolving belt and a oppositely situated slide; or(e) a rotatable feed roll and an oppositely situated freely rotatable further feed roll; or(f) a rotatable feed roll and an oppositely situated feed trough; orwherein, for all of the indicated possible embodiments (a) to (f) the conveying gap converges to a minimum width and at least one of the feed devices is pre-biased in the direction of the other feed device and is movable away from the other feed device by the force of the fiber flocks such that the spacing between both of the feed devices is changed in the sense that there is altered the minimum width x of the conveying gap, there is selectively determined the minimum width of the conveying gap or a value proportional thereto, and the surface velocity u of the driven feed device or feed devices is regulated such that at least the average value of the product x.multidot.u of this minimum width x and the surface velocity u remains essentially constant.

An apparatus for the opening-up and cleaning of cotton waste, especially strips, card fly and scutcher material and the like with a fiber material draw-in roller for feeding the fiber material to be cleaned to a saw tooth barrel the peripheral portion of which includes an opening-up section for opening-up the fiber material to be cleaned into individual fibers. When viewing the saw tooth barrel in its direction of rotation, the opening-up section is followed by a fiber material take-off roller rotatable in a direction counter to the direction of rotation of the saw tooth barrel. The apparatus furthermore includes a conduit having an inlet adjacent the peripheral surface of the saw tooth barrel for receiving fiber material therefrom and having an outlet for connection to a fiber material collecting container.

The machine accepts cut lengths of fibrous plant stem, and slices and cuts them into chips, and then crushes and squeezes them to partially defibered and de-watered condition. In the crushing and squeezing, the chips are fed by a pair of conveying endless chains to a squeeze-pass between circumferentially and chevron grooved rollers.

Coconut crumb can serve as an infill material on synthetic turf fields in the place of tire crumb. The crumbs are less than 10 mm big and have smooth corners and edges. The process of producing the coconut crumb involves successive grinding or milling processes that reduce the inner hard shell of the coconut to particles of an appropriate size for infill, while screening out the unwanted material from being included in the infill.

The present invention relates to the field of textiles. More specifically, it pertains to a process for producing and using fibrillated biodegradable microfibers. The process involves sourcing and preliminary processing plant materials encompassing cellulose-rich fibers followed by mechanical compression method or a solar powered electric presser to expel surplus moisture. Then, an aqueous immersion technique is employed for thermal processing to obtain thermal processed plant materials. The thermal processed plant materials then undergo a rinsing step and a mechanical disintegration step to reduce the thermal processed plant materials into micro-sized entities while maintaining the integrity of the fibers. Furthermore, matrix forming substances, stabilizer, sealant and preservative to said micro-sized entities subsequently undergoing a blending process to obtain a first mixture. Lastly, the first mixture is exposed to a controlled desiccation regimen followed by implementing a mechanical reduction process resulting in the attainment of said fibrillated biodegradable microfibers with a diameter measurement below the threshold of 10 μm.
