Definitions

  • the dried web is thereafter dislodged from the Yankee dryer with a doctor blade (creping), which serves to partially debond the dried web by breaking many of the bonds previously formed during the wet-pressing stages of the process. Creping can greatly improve the feel of the web, but at the expense of a significant loss in strength.
  • throughdrying has become an alternate means of drying paper webs.
  • Throughdrying provides a relatively noncompressive method of removing water from the web by passing hot air through the web until it is dry. More specifically, a wet-laid web is transferred from the forming fabric to a coarse, highly permeable throughdrying fabric and retained on the throughdrying fabric until dry. The resulting dried web is softer and bulkier than a conventionally-dried uncreped sheet because fewer bonds are formed and because the web is less compressed. Squeezing water from the wet web is eliminated, although the use of a pressure roll to subsequently transfer the web to a Yankee dryer for creping may still be used.
  • uncreped throughdried sheets are typically quite harsh and rough to the touch compared to their creped counterparts. This is partially due to the inherently high stiffness and strength of an uncreped sheet, but is also in part due to the coarseness of the throughdrying fabric onto which the wet web is conformed and dried.
  • an improved uncreped throughdried web can be made by transferring the wet web from a forming fabric to one or more intermediate transfer fabrics before further transferring the web to the throughdrying fabric for drying of the web.
  • the intermediate transfer fabric(s) is(are) travelling at a slower speed than the forming fabric during the transfer in order to impart stretch into the sheet.
  • the transfer fabric can be relatively smooth and dense compared to the coarse weave of a typical throughdrying fabric, but preferably is not as smooth as the forming fabric in order to provide some degree of friction to grip the web during transfer.
  • Gripping of the web is accomplished by the presence of knuckles on the surface of the transfer fabric.
  • one or more of the wet web transfers, with or without the presence of a transfer fabric are achieved using a "fixed gap" transfer which will be hereinafter described in detail.
  • the fixed gap transfer not only avoids compaction of the web while it is in a wet bond-forming state, but when used in combination with a differential speed transfer and/or a smooth transfer fabric, is believed to smooth out the surface of the web by scuffing its surface during the transfer.
  • the invention resides in a method of making a noncompressively-dried cellulosic web comprising: (a) depositing an aqueous suspension of papermaking fibers onto the surface of an endless travelling foraminous forming fabric to form a wet web having a consistency of from about 15 to about 25 weight percent; (b) transferring the wet web to a transfer fabric (hereinafter described) travelling at a speed from about 5 to about 75 percent slower than the forming fabric to impart stretch into the web; and (c) transferring the web to a drying fabric, preferably a throughdrying fabric, whereon the web is dried to final dryness in an uncreped state.
  • a transfer fabric hereinafter described
  • This method provides a means for producing webs with improved smoothness, stretch and relatively high caliper or thickness, as measured from one side of the web to another, particularly at relatively low basis weights. It is preferred that in transferring the web from one fabric to another, the transfer be carried out with a fixed gap between the two fabrics having a span equal to or greater than the thickness or caliper of the web so that the web is not compressed.
  • the invention resides in a method of making a noncompressively-dried cellulosic web comprising: (a) depositing an aqueous suspension of papermaking fibers onto the surface of an endless travelling foraminous forming fabric to form a wet web having a consistency of from about 15 to about 25 weight percent; (b) transferring the wet web to a drying fabric, preferably a throughdrying fabric, travelling at a speed from about 5 to about 75 percent slower than the forming fabric while maintaining a fixed gap between the forming fabric and the drying fabric; and (c) noncompressively drying the web.
  • the invention resides in an uncreped, uncalendered throughdried cellulosic web having a Surface Smoothness (hereinafter defined and described in connection with Figure 3) of about 81.3 ⁇ m (about 3200 micro-inches) or less, preferably about 63.5 ⁇ m (about 2500 micro-inches) or less, and more preferably about 38.1 ⁇ m (about 1500 micro-inches) or less.
  • a Surface Smoothness hereinafter defined and described in connection with Figure 3
  • increased smoothness is achieved through the use of the transfer fabric and, preferably, in combination with a fixed gap carrier fabric section following drying. Calendering of the web is not necessary to obtain these levels of smoothness, although it is within the scope of this invention that the smooth webs of this invention be further processed to further enhance the properties of the sheet, such as by calendering, embossing or creping.
  • the forming process and tackle can be conventional as is well known in the papermaking industry. Such formation processes include Fourdrinier, roof formers (such as suction breast roll), and gap formers (such as twin wire formers, crescent formers) etc. Forming wires or fabrics can also be conventional, the finer weaves with greater fiber support being preferred to produce a more smooth sheet or web. Headboxes used to deposit the fibers onto the forming fabric can be layered or nonlayered.
  • the basis weights of the webs of this invention can be any weight suitable for use as a paper towel or wiper.
  • Such webs can have a basis weight of from about 15 to about 60 grams per square meter, more suitably from about 20 to about 30 grams per square meter.
  • transfer fabric is a fabric which is positioned between the forming section and the drying section of the web manufacturing process.
  • Suitable transfer fabrics are those papermaking fabrics which provide a high fiber support index and provide a good vacuum seal to maximize fabric/sheet contact during transfer from the forming fabric.
  • the fabric can have a relatively smooth surface contour to impart smoothness to the web, yet must have enough texture to grab the web and maintain contact during a rush transfer. Finer fabrics can produce a higher degree of stretch in the web, which is desireable for some product applications.
  • Transfer fabrics include single-layer, multi-layer, or composite permeable structures. Preferred fabrics have at least some of the following characteristics: (1) On the side of the transfer fabric that is in contact with the wet web (the top side), the number of machine direction (MD) strands per cm (inch) (mesh) is from 3.94 to 78.74 cm (10 to 200) and the number of cross-machine direction (CD) strands per cm (inch) (count) is also from 3.94 to 78.74 cm (10 to 200).
  • MD machine direction
  • CD cross-machine direction
  • the strand diameter is typically smaller than 0.127 cm (0.050 inch); (2) On the top side, the distance between the highest point of the MD knuckle and the highest point of the CD knuckle is from about 0.00254 to about 0.0508 or 0.0762 cm (about 0.001 to about 0.02 or 0.03 inch).
  • the fabric In between these two levels, there can be knuckles formed either by MD or CD strands that give the topography a 3-dimensional characteristic; (3) On the top side, the length of the MD knuckles is equal to or longer than the length of the CD knuckles; (4) If the fabric is made in a multi-layer construction, it is preferred that the bottom layer is of a finer mesh than the top layer so as to control the depth of web penetration and to maximize fiber retention; and (5) The fabric may be made to show certain geometric patterns that are pleasing to the eye, which typically repeat between every 2 to 50 warp yarns.
  • transfer fabrics include, by way of example, those made by Asten Forming Fabrics, Inc., Appleton, Wisconsin and designated as numbers 934, 937, 939 and 959.
  • the void volume of the transfer fabric can be equal to or less than the forming fabric from which the web is transferred.
  • the speed difference between the forming fabric and the transfer fabric can be from about 5 to about 75 percent or greater, preferably from about 10 to about 35 percent, and more preferably from about 15 to about 25 percent, the transfer fabric being the slower fabric.
  • the optimum speed differential will depend on a variety of factors, including the particular type of product being made. As previously mentioned, the increase in stretch imparted to the web is proportional to the speed differential. For an uncreped throughdried three-ply wiper having a basis weight of about 20 grams per square meter per ply, for example, a speed differential in the production of each ply of from about 20 to about 25 percent between the forming fabric and a sole transfer fabric produces a stretch in the final product of from about 15 to about 20 percent.
  • the stretch can be imparted to the web using a single differential speed transfer or two or more differential speed transfers of the wet web prior to drying. Hence there can be one or more transfer fabrics.
  • the amount of stretch imparted to the web can hence be divided among one, two, three or more differential speed transfers.
  • the drying process can be any noncompressive drying method which tends to preserve the bulk or thickness of the wet web including, without limitation, throughdrying, infra-red irradiation, microwave drying, etc. Because of its commercial availability and practicality, throughdrying is a well-known and preferred means for noncompressively drying the web. Suitable throughdrying fabrics include, without limitation, Asten 920A and 937A, and Velostar P800 and 103A. The web is preferably dried to final dryness without creping, since creping tends to lower the web strength.
  • the side of the web not in contact with the throughdrying fabric retains its smoothness. Since the differential speed transfer has already occurred and the throughdrying fabric is not involved, there is no need for the web to be pulled deeply into the throughdrying fabric. Nevertheless, the side of the web in contact with the throughdrying fabric substantially conforms to the throughdrying fabric surface, rendering the other side of the web with a more textured macro-pattern.
  • the web consequently has a very two-sided appearance and feel, which is particularly advantageous for multi-ply products where the like sides (preferably the smoother sides) can be plied such that they are outwardly-facing. Alternatively, if desired, the more textured sides can be plied outwardly for improved surface cleaning, or one side of the product can be smooth and the other textured.
  • Figure 1 is a schematic process flow diagram illustrating a method of making uncreped throughdried sheets in accordance with this invention.
  • Figure 2 is schematic diagram of the transfer section of the method of Figure 1, illustrating more clearly the fixed gap transfer of the wet web from the forming fabric to the transfer fabric.
  • Figure 3 is a schematic diagram of the equipment set-up for determining the Surface Smoothness of a sample.
  • Figure 1 illustrates a means for carrying out the method of this invention.
  • a papermaking headbox 10 which injects or deposits a stream 11 of an aqueous suspension of papermaking fibers onto the forming fabric 13 which serves to support and carry the newly-formed wet web downstream in the process as the web is partially dewatered to a consistency of about 10 dry weight percent.
  • the forming fabric After formation, the forming fabric carries the wet web 15 to an optional hydroneedling station 16 where the web can be hydroneedled to increase its bulk.
  • Suitable means for hydroneedling are disclosed in U.S. Patent No. 5,137,600 issued August 11, 1992 to Barnes et al. and entitled “Hydraulically Needled Nonwoven Pulp Fiber Web", which is herein incorporated by reference.
  • Such means provide a multiplicity of pressurized water jets which impinge upon the surface of the newly-formed wet web while supported on the forming fabric, causing an increase in the porosity of the web and hence an increase in bulk.
  • additional dewatering of the wet web can be carried out, such as by vacuum suction, while the wet web is supported by the forming fabric.
  • the Fourdrinier former illustrated is particularly useful for making the heavier basis weight sheets useful as wipers and towels, although other forming devices can be used.
  • the wet web is then transferred from the forming fabric to a transfer fabric 17 travelling at a slower speed than the forming fabric in order to impart increased stretch into the web. Transfer is preferably carried out with the assistance of a vacuum shoe 18 and a fixed gap or space between the forming fabric and the transfer fabric to avoid compression of the wet web.
  • the wet web is then transferred to a throughdrying fabric 19 travelling at about the same speed, or a different speed if desired, and dried to final dryness as the web is carried over a throughdryer 20.
  • the dried web 22 Prior to being wound onto a reel 21 for subsequent conversion into the final product form, the dried web 22 can be carried through one or more optional fixed gap fabric nips formed between carrier fabrics 23 and 24.
  • the bulk or caliper of the web can be controlled by fabric embossing nips formed between rolls 25 and 26, 27 and 28, and 29 and 30.
  • Suitable carrier fabrics for this purpose are Albany International 84M or 94M and Asten 959 or 937, all of which are relatively smooth fabrics having a fine pattern.
  • Nip gaps between the various roll pairs can be from about 0.00254 to about 0.0508 cm (about 0.001 inch to about 0.02 inch).
  • the carrier fabric section of the machine is designed and operated with a series of fixed gap nips which serve to control the caliper of the web and can replace or compliment off-line calendering.
  • Figure 2 more clearly illustrates the transfer fabric section of the process disclosed in Figure 1. Shown is the forming fabric stretched between rolls 31 and 32, between which the wet web 15 leaves the forming fabric and is transferred to the transfer fabric 17. Transfer shoe 18 is provided with a source of vacuum to assist in transferring the wet web to the transfer fabric.
  • the surface of the transfer fabric is relatively smooth in order to provide smoothness to the wet web.
  • the openness of the transfer fabric as measured by its void volume, can be relatively low and can be about the same as that of the forming fabric or even lower.
  • the transfer fabric is travelling at a slower speed than the forming fabric.
  • the speed differential is preferably from about 20 to about 30 percent, based on the speed of the forming fabric. If more than one transfer fabric is used, the speed differential between fabrics can be the same or different. Multiple transfer fabrics can provide operational flexibility as well as a wide variety of fabric/speed combinations to influence the properties of the final product.
  • a feature of the transfer fabric section illustrated is the fixed gap between the forming fabric and the transfer fabric at the point of transfer of the web, which coincides with the position of the transfer shoe.
  • the width of the fixed gap is about the thickness of the wet web or even slightly greater in order to avoid or at least minimize compression of the web during transfer.
  • the fixed gap will be about 0.0635 cm (about 0.025 inch), but will vary with the amount of stretch imparted to the web since increased stretch results in a greater degree of web expansion at the transfer point.
  • the level of vacuum used for the fixed gap transfers can be from about 76.2 to about 381 mm (about 3 to about 15 inches) of mercury, preferably about 127 mm (about 5 inches) of mercury.
  • the vacuum shoe (negative pressure) can be supplemented or replaced by the use of positive pressure from the opposite side of the web to blow the web onto the next fabric in addition to or as a replacement for sucking it onto the next fabric with vacuum.
  • a vacuum roll or rolls can be used to replace the vacuum shoe(s).
  • the Surface Smoothness test measures the smoothness of a surface of a tissue sheet in a way that mimics the response of a human observer gently feeling the surface of the sheet with the fingertips. Either side of the sheet can be measured.
  • the test is based on measurement of the surface profile of a tissue specimen at a nominal angle of 45 degrees with respect to the machine direction of the sheet.
  • the standard deviation of the surface profile is obtained for special frequencies between 0.98 and 8.86 cycles per cm (2.5 and 22.5 cycles per inch) in order to include only those components of surface roughness that are important to human tactile response for tissue, towel or wiper products.
  • the test is based on a surface profile measuring instrument that scans the sheet at a rate of 0.254 cm (0.1 inch) per second with a 50-milligram tracking force placed on a 0.0508 cm (0.020 inch) diameter ball tip stylus. Since the surface topography of any tissue surface has a high degree of variability, the length of the profile scan line should be greater than 25.4 cm (10 inches) to ensure statistically valid results. Since standard profile instruments do not have the capability to scan such large distances, the test is based on an instrument that scans approximately 3.81 cm (1.5 inches). In order to obtain a larger total scan distance, the test specimen is translated in the direction normal to the profile scanning direction within the plane of the test specimen.
  • This sample translation is done at a speed approximately one-fortieth as fast as the profiling instrument scanning rate. This results in the stylus tracing a zig-zag back and forth across the tissue sheet such that a total path of greater than 25.4 cm (10 inches) can be obtained without sampling a given position more than once.
  • the output signal of the profile measuring instrument is passed into a signal analyzer where the amplitude information in the frequency range of interest is extracted. This information is integrated into an RMS average number representing the standard deviation of the signal in the frequency range of interest.
  • the specific test equipment includes:
  • the Surfanalyzer and translation table are mounted on a Newport Corporation (of Fountain View, California) Research Series Table Top (air table) to isolate them from any room floor vibrations. Specifically, the surfanalyzer is set on this table. The probe translation is switched on until the probe is centered in its translation range. Then, the translation table is placed so that its center is directly under the probe tip. The translation table is carefully aligned so that its axis of movement is orthogonal to the axis of movement of the Surfanalyzer probe.
  • Figure 3 illustrates a schematic diagram of the equipment set-up for measuring the Surface Smoothness of a sample. Shown is the Surfanalyzer control unit 40, the SD 380 Signal Analyzer 41, the Surfanalyzer servo unit 42, the translation arm 43, the probe 44, the stylus tip 45, the tissue sample 46 mounted on a glass slide, the translation table 47 with the direction of movement normal to the face of the page, and connecting cables 48.
  • the SD380 signal analyzer has many other "controls", the setting of which is not consequential to this test.
  • Samples for the Surface Smoothness test must be properly mounted to a glass microscope slide in order to obtain meaningful results. Specifically, samples are placed on a clean Corning Micro-Slide, Number 2947, 7.62 cm by 2.54 cm (3 inch by 1 inch) in size, nominally 1.0 millimeter thick. (These slides are available from Baxter Diagnostics, Inc. of McGaw Park, Illinois). In order to avoid sample slippage, which will invalidate test results, samples are bonded to these slides by the use of 3M Scotch-brand double-coated mylar tape #415. The tape is available from McCaster-Carr Supply Company of Chicago, Illinois). The samples are mounted by the following procedure:
  • Specimens are tested by placing the specimen slide on the translation table with the specimen side up.
  • the slide is aligned so that its longer dimension parallels the probe scanning direction of the Surfanalyzer. It is positioned so that the Surfanalyzer stylus, when fully extended, is positioned about 0.635 cm (about 1/4 inch) from the corner of the specimen slide, towards the center of the slide along the slide diagonal.
  • the Surfanalyzer translation (scanning) motion is switched on and the translation table is started in the direction that moves the centerline of the slide towards the stylus tip.
  • the Surfanalyzer stylus is adjusted vertically down onto the sample until the signal analyzer time domain display indicates that the signal trace is evenly split about the zero voltage level, indicating nominal centering of the stylus travel within its measurement range.
  • a delay of 40 seconds is required so that all data acquired during stylus centering is passed from the signal analyzer memory.
  • the cleared signal analyzer averager memory is switched on.
  • the averager will run for 120 seconds of spectrum data acquisition, after which time the averager will automatically switch off, indicated by the extinguishing of a panel light. At this point, the translation table and Surfanalyzer translations are switched off and the stylus is raised off the specimen to allow the removal of the slide.
  • a precursor of the Surface Smoothness value is read off of the signal analyser spectrum averager by integrating the average spectrum signal from 0.25 to 2.25 Hz using the "delta P" cursor mode.
  • the "delta P” mode integrates the square of the displayed magnitude spectra to give the RMS "power" within the frequency range of interest.
  • the output units are volts.
  • the numbers off the signal analyzer must be multiplied by the ratio of micro-inches of stylus displacement per volt of output of the Surfanalyzer to convert to units of ⁇ m (micro-inches).
  • the auxiliary output voltage represents 40.64 ⁇ m (1600 micro-inches) per volt. Therefore, the "delta P" value is multiplied by 1600 to convert the units from volts to micro-inches.
  • the temporal frequency range of 0.25 Hz to 2.25 Hz corresponds to a spacial frequency of 0.98 to 8.86 cycles per cm (2.5 to 22.5 cycles per inch).
  • the Surface Smoothness value is therefore equivalent to the frequency partitioned standard deviation of the specimen surface profile between the frequencies of 0.98 and 8.86 cycles per cm (2.5 and 22.5 cycles per inch).
