Therefore, in the case of thin paperboard, "all dry weight percentages refer to thin paperboard that has been aged for three weeks and thus balanced with the surrounding conditions. The dry weight percentage is defined by chemical extraction and extract analysis. If processed, the basis weight of the paperboard is known before treatment, and the treated basis weight of the treated tissue is subtracted from the treated basis weight of the treated tissue. The treated basis weight of the treated tissue is multiplied by 100.

After the tissue product was made, the geometric mean tensile strength, wettability (wetness time ' as described above) and softness were carried out. The thin cardboard is manufactured as follows. The wet-pressed tissue paper is used to produce a paper substrate which is produced by a conventional wet-added tissue paper method well known to those skilled in the art.

The thick paper miscellaneous "containing the debonding agent" is then redispersed in the water towel - and is used as the outer paper in the tissue making process. The cork pulp fibers were beaten for 3 minutes at 4% consistency, after which they were diluted to a 2 2% consistency, while the debonded eucalyptus pulp fibers were diluted to a consistency. The total stratified paperboard weight, between the eucalyptus/refined softwood/eucalyptus pulp fiber layer, is divided into about 30% / about 40 〇 / 〇 / about 30%. The intermediate layer is refined to achieve the desired target strength value while the outer layer provides surface softness and bulk. A three-layer feed bin for forming wet paperboard in which refined softwood kraft paper is stacked in two central layers of the feed bin to produce a single center layer of the three-ply tissue product. A turbulent flow of 3 inches (75 mm) at the rear end of the sheet was used to produce an inserter' and a layer separator having an extended sheet of about 1 inch (25.4 mm). The net flake openings are approximately ο" inches (23 mm) and the water flow in all four feed bin layers is comparable. The consistency of the feedstock fed to the feed was about 〇.〇9 weight percent. The finished three-layer paperboard is formed on the roller of the double-layer metal mesh, which is a forming machine, and the formed fabrics are Lindsay 2164 and Asten 867A, respectively. The speed of the forming fabric was 11.9 meters per second. The freshly formed tissue was dewatered to a consistency of from about 20 to about 70% from the underside of the forming fabric before being transferred to the transfer paper at a moving speed of 9.1 m/sec (30% sprint). The transfer fabric is Applet〇n wire T8〇7_ w吏, which is used to pull the cardboard to a conveyance fabric by pulling up about 6-15 inches (150-380 mm) of mercury. The cardboard is then transferred to a breathable, dry fabric (Linday wire T1205-1). The dried fabric was conveyed through a honeycomb (H〇ney COmb) dryer operating at 35 F (175 dc) and dried to a dryness of about 94-98 consistency. 17 (:.\@ΕυηΑ»200β{§ν>Κ·ΰΟ1-(10) 200914683 The finished unwrapped thin cardboard is wound onto a female roller.

The method was set to a condition, the gap between the 375-inch sigmographic concave wheel and the rubber back roller, and The gap between the surfaces of the thin rubber back roller is at the same time. At the same time, the offset/offset gravure printing machine performs the addition of _ _ _ _ _ _ _ _ _ _ _ _ _ Obtain the desired rate of addition. The gravure roller speed difference used in this example is 5 (8) gram per minute. The method produces a _ body addition level of 2 〇 weight percent based on the weight of the finished tissue. The cardboard is then transported to Water bath thin paper rollers. The softness and stiffness of thin paper products are provided by trained in-handranking pands, which provide a basis for softness and stiffness estimation of tissue paper products.

Each sample decoded by the panel is produced. The ranks and other data were analyzed using the proportional hazards regression model. Evaluate the model numerically: The panel list' performs the ranking process from the most frequently estimated attributes to the least ordered order of attributes. The softness and stiffness test results are presented in the table below, which is a log odd value. The log odd value is the logarithm of the natural risk ratio, which is estimated by each code of the proportional regression regression model. Larger l〇g odd values indicate that the property of interest is perceived by greater intent.

The sample is prepared as described above using a gravure coating formulation onto both surfaces of a single layer of tissue substrate. 2 The dry weight percentage of total active agent added (each side i dry weight ratio) was uniformly applied to both sides of the substrate. The treated substrate was then converted into a bath tissue roll and tested for softness and absorbency. The test results are shown in Table 2 and the first figure.

A (2.4454) * "A" is clearly Na, soft, but only directional is softer than "ab". "ab" is associated with greater softness than "c" = softer, etc. Larger, lower softness. Therefore, the higher wealth is what the sleeves want. WA is obviously stiffer than "B", but only directional is stiffer than "AB". "AB" is harder than "c". The souther position number is related to larger stiffness. Larger negative It is related to the lower stiffness. Because the stiff scale is recorded in the product - it is converted, so the lower number is more we want. As further illustrated in the first figure, the result shows AF-2340 poly stone.

Example 3 A tissue softening formulation containing the genus number 1: polygala (AF-2340), an aliphatic alkyl derivative (Tergitol 15-S-9), and glycerin was prepared. AF-2340 is an aqueous emulsion of an amine polyoxyalkylene which contains about 35 weight percent of an amine polyoxyxane fluid (AF_23) and a formulation aid. The amounts of polyoxyalkylene, aliphatic alkyl derivatives and glycerol in the formulation are described in Table 5. A thin paper sample was prepared by gravure coating a layer of unbleached, dry tissue paper substrate as described above. 2 The total active agent addition amount of dry weight percentage (1 weight% on each side of the mother side) is uniformly applied to the auxiliary enamel of the substrate. The treated substrate was then subjected to Lai (4) bath paper and tested for softness and absorbency.
