Definitions
- the present invention relates to a tissue web, more particularly to a printed tissue web, a method for preparing and use of same.
- tissue products such as bath tissue
- coloring the tissue is accomplished by the addition of a colored dye to the fiber furnish prior to the formation of the wet laid web.
- Product color changes are effected by running all of the dyed furnish out of the papermaking machine, rinsing the system, and starting up again with a new color. There is considerable waste and delay associated with this type of operation due to the down time necessary for purging the papermaking machine of the prior color, as well as placing limitations on recycling colored broke.
- the object of the present invention is to provide a tissue web being printed on one surface with a colorant without affecting the other surface and a method for making same.
- This object is solved by the method of independent claim 1 and the tissue web of independent claim 9. Further advantageous features of the method are evident from dependent claims 2 to 8 and further advantageous features of the tissue web are evident from dependent claims 10 to 18.
- Independent claim 19 provides a use of the tissue web. Further advantages and preferred embodiments of the tissue web, the method for preparing and use of same are evident from the following specification, the examples and drawings given in the figures.
- the tissue web can be printed with an ink, dye, or whitener/brightener (all hereinafter referred to as colorants) to impart an overall pattern (hereinafter defined) of small colored areas to the tissue web which, in the eye of an ordinary observer, gives the appearance of a solid color on the printed side as if the tissue furnish were colored conventionally.
- colorants an ink, dye, or whitener/brightener
- tissue webs are typically verythin, highly absorbent and weak, particularly when exposed to aqueous solutions, and would be expected to fall apart, or at least permit the color to bleed through if exposed to a printing process. Nevertheless, it has been found that one side of such webs can appear to be solidly colored without adversely affecting the properties of the tissue required for its end use.
- color includes true color, such as the colors of the visible spectrum, as well as white and different levels of brightness.
- true colors the printed side of the tissue web appears to be a solid color and the presence of the unprinted background area of the same tissue web surface, if white, imparts to the color a higher degree of brightness than a conventionally dyed web of the same color would have.
- a major advantage of the process of this invention is that a tissue machine can be operated making only white tissue, thus eliminating color changes and the associated down times and start-up problems as well as reducing inventories of different colored rolls.
- the invention is not limited to printing on white tissue.
- the tissue can be of one color prior to printing and thereafter printed to achieve a different color on one or both sides.
- a series of printing stations can be used to print a combination of primary colors to achieve any desired apparent color such as, for example, printing blue followed by printing yellow to obtain green.
- the invention resides in a method of making a colored tissue web comprising printing the surface of a tissue web with a colorant to provide an overall printed pattern of small colored areas, wherein the small colored areas cover at least about 5 percent of the surface area of the overall printed pattern of the tissue web without rendering the tissue web unsuitable for use.
- a method of making a colored crepe tissue web comprising printing the surface of a creped tissue web with a colorant in an overall pattern of small colored areas, wherein the percentage of the surface area of the overall pattern covered by the small colored areas is at least about 5 percent or greater.
- the surface area coverage is from about 10 to about 60 percent, and most preferably from about 15 to about 40 percent.
- the surface area coverage is from about 10 to about 60 percent, and most preferably from about 15 to about 40 percent.
- the invention resides in a tissue web, at least one of the two outer surfaces of which contains an overall printed pattern of small colored areas which are of a color different from the remaining area of the tissue surface, said small areas of different color covering at least about 5 percent of the total surface area of the overall printed pattern of the tissue web and imparting a solid color appearance to the printed surface.
- a creped tissue web in which at least one of the two outer surfaces contains an overall pattern of small colored areas which are of a color different from the remaining area of the tissue surface, said small colored areas covering at least about 5 percent of the surface area of the overall pattern of the tissue web.
- tissue web is a cellulosic web suitable for making or use as a facial tissue, bath tissue, paper towels, or the like. It can be layered or unlayered, creped or uncreped, and is preferably a single ply web, but can also be of two or more plies. In addition, the tissue web can contain reinforcing fibers for integrity and strength.
- Tissue webs suitable for use in accordance with this invention are characterized by being absorbent, of low density and relatively fragile, particularly in terms of wet strength. Densities are typically in the range of from about 0.1 to about 0.3 grams per cubic centimeter. Absorbency is typically about 5 grams of water per gram of fiber, and generally from about 5 to about 9 grams of water per gram of fiber.
- Wet tensile strengths are generally about 0 to about 300 grams per inch* of width and typically are at the low end of this range, such as from about 0 to about 30 grams per inch. Dry tensile strengths in the machine direction can be from about 100 to about 2000 grams per inch of width, preferably from about 200 to about 350 grams per inch of width. Tensile strengths in the cross-machine direction can be from about 50 to about 1000 grams per inch of width, preferably from about 100 to about 250 grams per inch of width. Dry basis weights are generally in the range of from about 5 to about 60** pounds per 2880 square feet***.
- the tissue webs referred to above are preferably made from natural cellulosic fiber sources such as hardwoods, softwoods, and nonwoody species, but can also contain significant amounts of recycled fibers, sized or chemically-modified fibers, or synthetic fibers. After printing, the tissue webs can be plied together to form multiply tissue products.
- an "overall pattern” is a printed pattern which macroscopically covers substantially the entire surface of the tissue web, as viewed in the eye of a casual observer such as a typical tissue user. Although macroscopic coverage of the entire surface of the tissue web is preferred, it is within the scope of this definition that the overall pattern macroscopically cover less than the entire surface of the tissue web.
- An example of covering less than the entire surface of the tissue web includes, without limitation, a tissue web having decorative unprinted areas interspersed within the overall pattern, such as a butterfly or floral pattern. In such a situation, for example, a roll of blue bath tissue having a decorative white floral pattern can be produced by printing an overall pattern of blue onto a white tissue web, but leaving individual unprinted areas having the shape of a flower.
- the printing operation to not apply colorant in the white decorative areas.
- Other examples of less than total surface coverage include leaving the edges of the tissue web unprinted or leaving unprinted areas which are in the form of alphanumeric indicia.
- the overall pattern macroscopically cover from about 75 to about 95 percent of the surface area of the tissue web, and most preferably from about 85 to about 95 percent in order to give the appearance of a solid background color.
- the surface area coverage provided by the small colored areas making up the overall pattern is at least about 5 percent of the surface area of the overall pattern of the tissue web.
- surface area is the planar area of the tissue web as viewed from above in a plan view. Surface contours in the web are not taken into account.
- the surface area coverage is from about 5 to about 60 percent, more preferably from about 5 to about 25 percent, and most preferably from about 5 to about 15 percent.
- a surprising advantage of printing webs in accordance with this invention is that in most instances the printed web can be immediately embossed after printing because drying of the web is almost instantaneous. Hence an embossing module can be positioned in line immediately downstream of the printing operation.
- the degree of penetration of the ink into the tissue web should be limited as much as possible to avoid using unnecessary amounts of ink and to avoid substantially affecting the properties of the tissue web. This is particularly true for water-based inks, which can adversely affect strength, stiffness and density of the tissue web by introducing additional bonding within the tissue.
- the inks are confined to the outermost fibers. This is most easily accomplished with pigment-based colorants containing polymeric vehicles, whereas substantive dyes have a greater tendency to migrate and penetrate the tissue web.
- penetration is preferably limited to an average of about 60 percent of the web thickness or less. More preferably, the penetration of colorant is limited to about 30 percent or less of the web thickness, and most preferably about 20 percent or less.
- a substantially uncolored appearance on the unprinted side means that the color difference between the printed side and the unprinted side of the web is substantial and the color of the unprinted side is minimally affected by the printing of colorant on the printed side.
- the color difference is at least 20 percent, and preferably at least 30 percent, as measured by averaging the percent change of the Hunterlab Color "a” and "b" values (hereinafter defined) from one side of the web to the other side.
- the formula for calculating this color difference is: 50[2-(a1/a2)-(b12/b2)], wherein "a1" and “b1” are the Hunterlab Color “a” and “b” values for the unprinted side of the web and "a2" and “b2” are the Hunterlab Color “a” and “b” values for the printed side of the web. If both sides of the web are printed, for purposes herein "substantially uncolored” means that the printing of one side has no substantial effect on the color of the unprinted side. In either case, the colored web has substantially the same density and stiffness (softness) as the untreated or uncolored web prior to printing.
- Single ply webs of this invention can be combined into a two ply product having the printed sides out, or can be utilized as a one ply product having sides of two different colors.
- the tissue web is wound onto a roll such that only one side of the web is displayed during end-use, it is advantageous to have the printed side out and the unprinted side in.
- the method of this invention can be applied to both sides of a single ply web if a single ply product having both sides of the same or different colors is desired.
- decorative patterns can be printed on top of the overall-printed web.
- the add-on amount of colorant will be as little as possible while sufficient to impart the desired color to the tissue web.
- the amount will depend upon the nature of the particular tissue web being treated, but in general can be from about 0.1 to about 3 milligrams per square inch of surface per side, and preferably from about 0.2 to about 1.5 milligrams per square inch.
- the method of this invention can be applied at any point in the manufacturing process after the tissue web is sufficiently dry to accept the colorant being printed thereon. It is convenient to print the tissue between manufacturing and converting, thus avoiding any difficulties associated with high manufacturing line speeds.
- the tissue web can be printed between the parent roll (soft roll) and the hardroll during rewinding.
- the tissue web can be printed as the hardroll is being unwound, prior to cutting or slitting. If a creped tissue web is used it can be printed between the creping cylinder and the parent roll or between drying and the creping doctor blade if desired. In any case, it is preferred that the printing precede any embossing step which would impart surface irregularities and make overall printing more difficult.
- in-line embossing of the printed tissue web immediately following the printing step is easily accomplished.
- In-line printing immediately followed by embossing is an unexpected combination because printing to obtain overall coloration of a tissue web would ordinarily be expected to leave the web too moist to process or, at a minimum, too moist to achieve good embossing definition.
- rotogravure printing which is a common, well known printing process, be used to apply the colorant to the tissue web because of the high degree of control provided by the rotogravure process.
- other printing methods can also be used such as, without limitation, offset gravure, flexographic, rotary screen, offset lithography and letter press.
- the method of this invention also can be utilized to deliver additional substances such as adhesives, web strength additives, lotions, fire retardants, disposal aids, and the like.
- Suitable colorants for printing onto the tissue web include solvent- and water-based inks and substantive dyes in an unlimited range of colors.
- the amount of colorant applied to the tissue web will depend upon the particular colorant composition, its color intensity, and the desired color intensity of the final product.
- the size of the small colored or brightened areas imparted to the tissue web by the printing method described herein must be sufficiently small so that they are not individually detectable by the naked eye. Because of the irregular shape of the colored or brightened areas, which is particularly true when using dyes which readily wick along the fiber network of the tissue web, the size of these printed areas can be specified with only limited precision. The spacing of these printed areas will depend upon their size and the desired surface area coverage, as well as the particular colorant being used.
- RGBColor a well known color measurement which is expressed in terms of three values: Rd, "a", and "b".
- Rd represents the percent diffuse reflectance (brightness) which ranges from 0 (black) to 100 (white).
- the "a” value is a measure of the redness (+a) and greenness (-a).
- the "b” value is a measure of yellowness (+b) and blueness (-b). For both the "a” and “b” values, the greater the departure from 0, the more intense the color.
- a stack of tissue samples is placed on the Hunterlab Color Difference Meter beneath the optical light sensor.
- the reason it is necessary to use a stack of the sample tissues is that the sample must be sufficiently thick to prevent light from penetrating the sample and reflecting back through the sample from the background sample support surface to give a false reflectance reading.
- tissue samples having a basis weight of from about 7 to about 20 pounds per 2880 square feet per ply about 40 plies are needed to form the stack. The number of plies will of course vary with the density and thickness of the test sample. In all cases, it is necessary that the test side of each ply within the sample stack be facing toward the optical light sensor.
- FIG. 1 is a schematic diagram of a rotogravure printing unit useful in the method of this invention. Shown is a tissue web 1 being passed between a rubber impression roller 2 and a gravure cylinder 3. The surface of the gravure cylinder contains a large number of depressions or cells 4 which are designed to receive, hold, and transfer colorant to the tissue web. .Colorant or brightener 5 is applied to the surface of the gravure cylinder downstream of the nip and is removed from the land areas of the gravure cylinder with a doctor blade 6.
- the tissue web As the tissue web enters the nip area, it is pressed against the gravure cylinder by the rubber impression roller, thereby permitting the colorant or brightener to transfer from the gravure cylinder cells and be deposited on the surface of the tissue web in small colored or brightened areas 7 corresponding to the individual gravure cylinder cells.
- the overall pattern of small colored or brightened areas remains relatively intact in the final tissue product.
- the percentage of the surface area of the tissue web covered by the colored areas will closely match the percentage of the surface area of the gravure roll covered by the gravure cells. However, as will be illustrated in Figure 3, this relationship may not hold when using dye inks which have a greater tendency to migrate.
- the overall pattern of the tissue web will appear to be a solid color.
- the rotogravure cell size and the number of cells per square inch will depend on a number of factors, including the flow characteristics of the colorant, the intensity of the colorant, the desired surface area coverage.
- the loading between the rubber impression roller and the gravure cylinder should be as low as possible to avoid permanent compaction of the tissue web, suitably about 100 pounds per lineal inch (pli) or less, and preferably about 40 pli.
- the rubber impression roller correspondingly can have a hardness of about 90 Shore A durometer or less, preferably about 70. Operation of the printer should be such as to avoid decreasing the bulk of the tissue web, which means not only minimizing the nip pressure, but also minimizing the amount of moisture added to the tissue web during printing in order to minimize the formation of new papermaking bonds.
- 1 ft.min 30.48 cm/min
- Web speeds through the rotogravure printing process can be from about 600 or less to about 5000 feet per minute*, allowing the printing to be accomplished on-line during web manufacture or subsequently during converting.
- FIG 2 is a plan view photograph (10x) of a creped tissue web in accordance with this invention.
- the photograph illustrates an example of a degree of overall surface coverage suitable to achieve the appearance of a solid color as viewed by an ordinary observer or end-user of the product.
- Shown is the creped tissue web surface and a multiplicity of small colored areas 21, which in this instance are deposits of a water-based pigment ink (blue, manufactured by Converters Ink Company, Neenah, WI) covering about 20 percent of the surface area of the tissue web.
- a water-based pigment ink blue, manufactured by Converters Ink Company, Neenah, WI
- the same rotogravure roll when using a substantive dye colorant, will produce small colored areas which immediately transform into a pattern vastly different in character than that shown in Figure 2. (See Figure 3).
- Figure 3 illustrates a different embodiment of this invention in which the tissue web has been printed with an overall pattern of small blue colored areas 21 using a substantive dye ink.
- the shape or nature of the small colored areas imparted to the tissue web by the gravure cylinder has changed dramatically because the dye migrates along the surface fibers.
- these colored surface fibers are considered to be small colored areas, notwithstanding that their shape is very irregular and no longer corresponds to the shape of the gravure cell.
- the percentage of surface area coverage provided by the colored or brightened areas can be determined using image analysis, provided the colorant or brightener can be distinguished from the base color of the tissue web.
- Figure 4 is a cross-sectional photograph (100x) of a creped tissue web in accordance with this invention, further illustrating the nature of the small colored areas 21, which in this case are blue dye ink deposits of the type illustrated in Figure 3. As shown, although the dye inks have a greater tendency to penetrate the tissue web surface, the colored areas 21, which are outlined with a solid line, are still substantially confined to the surface of the tissue web.
- Example 1 Water-based pigment ink (beige)
- a white single-ply creped tissue web having a finished basis weight of 17.4 pounds per 2880 square feet and a furnish consisting of 60% hardwood and 40% softwood fibers, was printed on one side with a beige water-based dye ink (W126105 Series 5 Beige supplied by Converters Ink Company, Linden, N.J.).
