摘要： An improved method for creating fibers from a material dissolved in a solvent. In one embodiment, the method includes the steps of feeding a fiber making material dissolved in a solvent through a die including at least two rows of nozzles to form fiber strands. An attenuation medium is provided about the fiber strands. The attenuation medium is provided in a direction that is generally parallel to the fiber strands such that the attenuation medium elongates the fiber strands. The attenuation medium has a relative solvent-vapor content of at least about 50 percent.

摘要： A papermaking vacuum apparatus having a web-facing surface adapted to support a papermaking belt and comprising a head, a body and at least one vacuum slot disposed in the head and defining an aperture on the web-facing surface. The vacuum slot is in fluid communication with the web-facing surface and extends from the web-facing surface to the body which is in further fluid communication with a vacuum source. The web-facing surface comprises a leading surface and a trailing surface. The leading surface has a transitional area juxtaposed with the aperture created by the vacuum slot. This transitional area has a predetermined Z-directional spacing from the papermaking belt, which Z-spacing continuously and gradually increases in the machine direction whereby the amount of vacuum pressure applied through the vacuum slot to the paper web gradually increases as the paper web travels in the machine direction over the slot.

The vacuum slot is in fluid communication with the web-facing surface and extends from the web-facing surface to the body which is in further fluid communication with a vacuum source. The vacuum apparatus has a flow management device facing said web-contacting surface of the papermaking belt and disposed such that the papermaking belt having the paper web thereupon travels between the flow management device and the web-facing surface of the head. The flow management device has an air flow resistance and controls the distribution of the air flow through the aperture on the web-facing surface such as to effectively increase in the machine direction the amount of vacuum pressure applied through the vacuum slot to the papermaking belt.

摘要： A micropore drying apparatus having a variable wet flow resistance. The flow resistance preferably decreases in the machine direction. The micropore drying apparatus may comprise a single integral unit having an decreasing wet flow resistance from the beginning to the end of the unit. Alternatively, the micropore drying apparatus may comprise a plurality of discrete units, each unit having a successively lesser flow resistance than that of the preceding unit. Alternatively, a hybrid arrangement may be used wherein each discrete unit has a successively decreasing flow resistance within that unit. The micropore drying apparatus may comprise one or more micropore drying media. The micropore drying media have pores which allow air flow therethrough. The pores are disposed in a grid, to form a field of pores. The decreasing flow resistance may preferably be provided by adjusting one or more of said pores, which affect the flow resistance through a single pore or through the entire field of the pores.

摘要： An apparatus for drying a cellulosic fibrous structure. The apparatus comprises a micropore medium having pores therethrough. The pores are the limiting orifice in the air flow used in the drying process. The micropore medium has a relatively low wet pressure drop therethrough. This relatively low wet pressure drop advantageously reduces the energy costs used in drying, and/or allows for greater drying to be obtained at constant energy costs.

摘要： A micropore drying apparatus having a noncircular profile. The apparatus has a machine direction and dries a web thereon as the web or apparatus moves in the machine direction. The micropore drying apparatus comprises a micropore drying medium which has pores therethrough smaller than the interstitials in the web to be dried thereon. The micropore drying medium may be movable or stationary, as desired. The noncircular profile may have a major axis which is substantially vertically oriented. This arrangement provides the advantage that greater residence time for the web to be dried thereupon is provided, without increasing the machine direction footprint.
