SYSTEMS AND METHODS FOR MANUFACTURING BULKED CONTINUOUS FILAMENT FROM COLORED RECYCLED PET
A method of manufacturing bulked continuous carpet filament from recycled polymer. In various embodiments, the method includes: (1) reducing recycled polymer material into polymer flakes; (2) cleansing the polymer flakes; (3) melting the flakes into a polymer melt; (4) removing water and contaminants from the polymer melt by dividing the polymer melt into a plurality of polymer streams and exposing those streams to pressures below 5 millibars; (5) recombining the streams; and (6) using the resulting purified polymer to produce bulked continuous carpet filament.
FOAMED PARTICLES OF AROMATIC POLYESTER RESIN, PRODUCTION METHOD THEREFOR, MOLDED FOAM, AND MEMBER FOR VEHICLE
An object of the present invention is to provide an aromatic polyester-based resin foam molded product having excellent mechanical properties, foamed aromatic polyester-based resin particles for producing the foam molded product, or a method for producing the foamed particles. The present invention relates to foamed aromatic polyester-based resin particles, wherein crystallinity (A) in a particle central portion and crystallinity (B) in a particle surface layer are both 10% or less, and a ratio of the crystallinity in the surface layer to the crystallinity in the central portion (B/A) is 0.3 to 1.4.
Nanofiber manufacturing device and nanofiber manufacturing method
According to the embodiment, a nanofiber manufacturing device that includes an ejector and a power generator is provided. The ejector is capable of ejecting a solution from a head portion toward a target. The power generator generates a potential difference between the head portion and the target. The head portion includes a first guide having a first surface and a second guide having a second surface, the first surface and the second surface making a gap, the gap being capable of maintaining the solution. A tip of at least one of the first guide and the second guide includes a maintain portion provided so as to be capable of maintaining the solution.
Photochemically cured millable polyurethane rubber
Photocurable millable polyurethane gum compositions contain a millable polyurethane gum having ethylenic unsaturation, photocatalyst, and a low molecular weight crosslinker containing minimally two ethylenically unsaturated groups. The compositions can be used to continuously extrude profiles which retain their shape.
Granulating Device Die, Granulating Device Cutter Blade Holder, Granulating Device Cutter Blade Unit, Resin-Cutting Device, Granulating Device, and Resin Pellet Manufacturing Method
Provided are a granulating device die, a granulating device cutter blade holder, a granulating device cutter blade unit, a resin-cutting device, and a granulating device, in all of which an increase in size is suppressed even when the processing amount is increased. The die (10) includes a bottom surface (10B), an upper surface (10A) having a radius smaller than a radius of the bottom surface (10B), a side surface (10C) that connects an outermost peripheral portion of the bottom surface (10B) and an outermost peripheral portion of the upper surface (10A), and a plurality of die holes (11) that discharge a resin raw material, the die holes being defined in the side surface (10C).
