초록 ▼

A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.

대표청구항 ▼

A process for making a strong, soft absorbent paper web comprising the steps of: (a) providing an aqueous dispersion of papermaking fibers; (b) forming an embryonic web of papermaking fibers from said dispersion on a foraminous surface; (c) contacting said embryonic web with the paper-contacting side of a papermaking belt, said papermaking belt comprising: a framework comprising a cured photosensitive resinous material, said framework having a first surface defining said paper-contacting contacting side of said belt, a second surface opposite said first surface, and conduits extending between said first surface and said second surface, said first surface having a paper side network formed therein defining said conduits, and said second surface having a backside network with passageways, distinct from said conduits, that provide surface texture irregularities in said backside network; and a reinforcing structure positioned between said first surface and at least a portion of said second surface, said reinforcing structure having a paper-facing side, a machine-facing side opposite said paper-facing side, interstices, and a reinforcing component comprised of a plurality of structural components a first portion of said reinforcing component having a first opacity and a second portion of said reinforcing component having a second opacity less than said first opacity, wherein said first opacity is sufficient to substantially prevent curing of said photosensitive resinous material which comprises the framework when said photosensitive resinous material is in its uncured state and said first portion is positioned between said photosensitive resinous material and an actinic light source, and said second opacity is sufficient to permit curing of said photosensitive resinous material, said first portion defining a first projected area; wherein said passageways in said backside network of said framework are positioned predominately within said first projected area, whereby said passageways let at least about 1,800 standard cc/min of air at a differential pressure of 7 inches of mercury enter between said backside surface of said papermaking belt and a vacuum source, thereby climinating a seal between said backside network and said vacuum source; (d) traveling said papermaking belt and embryonic web over said vacuum source and applying a fluid pressure differential to said embryonic web with said vacuum source such that the fluid pressure differential is applied from the backside of said papermaking belt through the conduits of said papermaking belt to deflect at least a portion of the papermaking fibers in said embryonic web into the conduits of said papermaking belt, and to remove water from said embryonic web through said conduits, and rearrange said papermaking fibers in said embryonic web to form an intermediate web from said papermaking fibers under such conditions that said deflecting is initiated no later than the initiation of the water removal from the embryonic web; (e) impressing said paper side network into said intermediate web by interposing said intermediate web between said papermaking belt and an impression surface to form an imprinted web of papermaking fibers; and (f) drying said imprinted web.
