摘要:
A hammermill for singulating cellulosic fibers from a wet pulp sheet includes a cylindrical housing, a feed slot with a breaker bar positioned therein and a rotor mounted for rotation in the housing. Feed rolls are provided to feed a sheet of pulp into the feed slot upstream of the breaker bar. A plurality of hammers are mounted on the rotor. Air is introduced into the hammermill housing tangentially downstream from the second feed slot. An air outlet is positioned tangentially on the housing downstream from the air inlet to allow air and singulated fibers to escape. A process for producing singulated fibers includes wetting a fiber sheet, milling the fibers in the hammermill, and drying the fibers. The singulated fibers have a low knot content.

An absorbent product manufacturing apparatus comprises a pulp feed mechanism (2) for feeding a pulp sheet along a lower surface of a pulp guide part (2411) and a pulp crushing mechanism (3) for crushing the pulp sheet from the pulp feed mechanism (2). The pulp crushing mechanism (3) crushes the pulp sheet with a first crushing cylinder (312) and a second crushing cylinder (322) provided, being inclined with respect to a direction of feeding the pulp sheet. This reduces a force of drawing the pulp sheet in the feeding direction and suppresses an increase in movement speed of the pulp sheet in crushing a near-rearend portion of the pulp sheet. As a result, it is possible to increase the amount of crushed pulp to be generated in a unit time and uniformity in quality thereof.

There is provided a photocatalytic pulp composition having the antibacterial, bad smell degrading and harmful substance oxidatively degrading effects in various wide uses such as a filter material, a packaging material, a building material. A photocatalytic pulp composition is effectively used in the air treatment, the water treatment and the soil treatment and improves the photocatalytic activity effect itself. There is provided a photocatalytic pulp composition characterized in that 40 to 95 wt % of a pulp and/or a paper having the water content of 3 wt % or less, the average fiber diameter of 5 to 300 nullm and the average fiber length of 0.1 to 70 mm is blended with 5 to 60 wt % of titanium oxide, and a photocatalytic pulp composition in which 25 to 100 wt % of a thermoplastic resin is blended relative to the total weight of titanium oxide, a pulp and/or a paper blended at the above ratio can be provided.
摘要:
A method is disclosed for preparing a quantity of individual treated fibers from one or more fiber mats in a treatment apparatus. The apparatus comprises a fiber treatment zone, a conveyor for conveying each mat through the fiber treatment zone, wherein each mat is impregnated by an applicator with a crosslinking substance, and directly to an attrition device. The attrition device fiberizes the mats to form a fiber output having a low nit level, such as no more than about three, and a dryer for both drying the fiber output and curing the crosslinking substance. The fiberizer is configured to have minimize the accumulation of fiber at locations therein. An optional component of the fiberizer is a novel fluff generator comprised of multiple rotors each having plural longitudinally extended rows of radially extending rotor pins that rotate past groups of shorter pins mounted on the inside surface of the fluff generator housing.
摘要:
A method and apparatus for fiberizing feed stock in the form of shreds or the like to form a low density cellulosic product. The shredded feed stock is fed to a material handling rotor that functions as a centrifugal blower. The apparatus includes a housing that defines a cylindrical rotor chamber formed about a horizontal axis and a volute-shaped internal passage having at least one convolution formed around the rotor chamber. Located within the housing is a cylindrical screen with perforations that open into the rotor chamber. The centrifugal blower rotor is mounted in the rotor chamber and has a plurality of radial vanes with rakes attached to the outer ends closely spaced from the inner surface of the screen so that they continuously wipe pass the perforations to prevent clogging or blinding.

Apparatus and process for continuously converting dried cellulosic fibrous sheet material into a dispersion of individual fibers in air and thereafter forming said individual fibers into an airfelt.
摘要:
Method and apparatus are provided for producing dry disintegrated cellulose pulp such as cellulose fluff from bales of cellulose pulp in sheet form, by cutting the pulp sheets in the bale into strips while still located in the bale, and thereafter defibrating the strips, with an optional intermediate shredding step prior to defibrating.
摘要:
Method and apparatus are provided for converting sheet cellulose pulp to defibrated pulp, uniformity of the defibrated pulp stock being ensured by pooling the shredded pulp obtained from a plurality of cellulose pulp sheets, and uniformly feeding the pooled shredded pulp fibers to the disintegrators.
