Methods and systems are provided for a composite material. In one example, the composite material includes a polymer base reinforced with a powder formed from pupunha fibers. The resulting composite material is provided as pellets for further processing.

A battery packaging material which is slim, has excellent moldability, effectively prevents curl after molding, and moreover, is capable of imparting sufficient surface insulation to a battery. This battery packaging material is configured from a laminate which is at least provided with a polyester film layer, an aluminum alloy foil layer, and a thermally-fusible resin layer in this order. The thickness of the polyester film layer is 23-27 μm, the thickness of the aluminum alloy foil layer is 33-37 μm, the thickness of the thermally-fusible resin layer is 55-65 μm, the thickness of the laminate is 130 μm or less, and the insulation breakdown voltage of the polyester film layer-side surface is 13 kV or greater.

A sheet manufacturing apparatus includes a second web forming unit that processes fibers into a web shape, a sheet forming unit that pinches and transports a second web processed into the web shape by the second web forming unit, and a control unit that controls at least any of a pressing state and a transport state in the sheet forming unit. The control unit causes the second web to pass through a nip unit by controlling at least any of a transport speed of the sheet forming unit, a nip pressure of the sheet forming unit, and a nip width of the sheet forming unit depending on a position of a leading edge of the second web with respect to the nip unit in which the sheet forming unit pinches the second web.

A sheet manufacturing apparatus includes a coarse crushing portion that crushes a raw material containing a fiber into coarse crushed pieces, a defibrating portion that defibrates the coarse crushed pieces into a defibrated material, a sieve portion that includes a plurality of openings, a sheet forming portion that uses the defibrated material passing through the opening of the sieve portion to form a sheet, and a transport passage that transports the defibrated material, which has not passed through the opening of the sieve portion, between the coarse crushing portion and the defibrating portion.

A tailings-reclaimed green stone paper processing method, which treats the tailings to meet the pH 7 pH requirement of the paper standard, grinds the treated tailings after drying, modifies the powdered tailings, implements a modified granulation process with the use of a modification aid, and then implements plastic granule stirring, heating mixing, filament spinning, cutting, papermaking and surface treatment processes to form an environmentally friendly stone fiber paper product, achieving the effects of tailings reuse, pollution-free, moisture-proof, anti-mite and low cost.

A storage portion includes a case which includes an internal space configured to accommodate raw material pieces having fibers, a discharge pipe coupled to a side wall of the case, and a transport motor which rotates the discharge pipe on an axis, in which one end in an axial direction of the discharge pipe communicates with the internal space and the other end has an outlet for discharging the raw material pieces, and a spiral member is provided on an inner peripheral surface of the discharge pipe.

A stirring apparatus includes a case that houses fiber pieces containing fibers, and a rotary body that is disposed inside the case and that stirs the fiber pieces, in which the rotary body includes a rotary portion that forms a portion of a bottom surface of the case and that rotates, and blades that stand upright on the rotary portion.

A date tree trunk-based lost circulation material (LCM) is provided. The date tree trunk LCM includes date tree trunk fibers produced from date tree trunks. The date tree trunks may be obtained from the date tree waste produced by the processing of date trees in the production of date fruits. The date tree trunk LCM may include fibers having lengths less than 8 millimeters (5 mm) and having an aspect ratio range of 10 to 15. Methods of lost circulation control using a date tree trunk LCM and manufacture of a date tree trunk LCM are also provided.

A fiber assembly-forming method includes forming a web containing a plurality of fibers charged to a first polarity on a transport belt charged to a second polarity opposite to the first polarity and applying a liquid to the web formed on the transport belt from a nozzle of a liquid coater. The liquid contains a binder binding the fibers.

Improved processes for liberating trichome fibers from non-seed portions of a trichome-bearing host plant are provided. The processes include one or more steps for disassociating trichome fibers that are already separated from leaves, stems, and still-attached fibers so that the separated trichome fibers can be collected and not lost through a waste stream.
