Definitions

  • the present invention relates to air laid (or dry laid) fibrous webs a portion of at least one surface being compacted by application of an imprinted pattern or design which pattern enhances the rate of absorption during use as well as improving the retention of liquid absorbed within the webs. More specifically, the invention relates to air laid cellulosic webs whose individual fibers are bonded together by an adhesive material essentially permeating said web, the bonded web having said pattern on at least one surface thereof, the compacted area thereof comprising at least about 40% of the total area per imprinted surface. Imprinting of the web surface(s) to this degree densifies those interior portions of the web underlying each compacted area thereby promoting capillary tension and wicking to enhance web absorbency and wiping characteristics.
  • the invention relates to tissue, towel and napkin products of high bulk and rapid absorbency obtained from bonded air laid cellulosic fibrous webs, in accordance with the method disclosed here.
  • a non-nesting pattern is imprinted on the web to prevent loss of final product size, e.g., product roll diameter.
  • Fibrous webs particularly low basis weight webs between 8 and 60 lbs.-per ream (3,000 sq.ft.), for use ultimately as tissue, towel and napkin products, are fabricated conventionally by two alternate processes.
  • the older wet laid process dispenses an aqueous slurry of pulped paper-making fibers, generally natural cellulose fibers, onto a moving foraminous support means, e.g., a fourdrinier wire, the aqueous medium being removed through the support means by vacuum means.
  • the wet laid web is thermally dried and taken up on a parent roll. Because of the presence of water, the wet laid fibers bond naturally to one another by means of hydrogen bonding.
  • Such conventionally prepared webs are sometimes creped to improve feel and enhance absorbency.
  • the webs may be embossed to enhance softness and-to provide a more aesthetic appearance.
  • the second, now conventional, yet relatively recent, process defiberizes cellulose pulp, the dry individual fibers being pneumatically transported to the dispensing means, and then dry laid (or air laid) onto the moving foraminous support means. Vacuum means below the support means is employed to ensure that the dry fibers remain on the web, which web has little inherent strength inasmuch as hydrogen bonds are not formed substantially in the absence of an aqueous medium.
  • the dry, initially laid web is then sprayed with a synthetic bonding agent, such as a latex emulsion, preferably on both surfaces of the web.
  • the bonding agent is cured by passing the thus treated web through a dryer, e.g., a through air dryer, before being taken up on a parent roll. These webs may also be creped and embossed.
  • wet laid webs provide better wiping absorbency than dry laid webs. That is, under dynamic conditions-of use, wet laid webs absorb liquid at a faster rate and retain the liquid thus absorbed better that their dry laid counterpart.
  • the slower rate of wiping absorbency associated with dry laid webs is primarily due to the greater volume of interstitial voids, existing within the reticulated structure of these webs.
  • the greater void volume is occasioned by the larger size, on average, of individual pores, as well as by the greater degree of reticulation extent in the overall web structure.
  • These interstitial voids provide a greater interstitial liquid holding capacity under static conditions, but permit absorbed liquid to be squeezed back out more easily under dynamic wiping conditions.
  • a pattern imprinted on at least one surface of a dry laid web wherein the compressed areas comprise at least 40% of the total imprinted area improves web absorption rate and enhances water retention during use.
  • patterned webs whether by imprinting or by embossing, have been produced to enhance the softness, improve the bulk, or to alter the strength and stretch characteristics of the web, as well as to impart an aesthetic design to the surface.
  • a raised pattern is formed on a portion of a first web surface (the raised portion), with corresponding depressions in the remaining portion of said web surface (the depressed portion).
  • These discontinuities in the first surface of the web are occasioned by passing the web between two cylindrical rolls, one of which is resilient, the other being inextensible and having a plurality of bosses thereon.
  • the bosses contact the second surface of the web forming the raised areas (and depressions) on the first surface in contact with the resilient roll.
  • the raises comprise about 20 to 30% of the total first surface area, the depressions accounting for the remaining area.
  • Imprinting compresses certain portions of a web surface in intaglio, the other surface not being raised thereby. Necessarily, imprinting densifies the compressed surface portions substantially more than embossing.
  • Imprinting as opposed to embossing, has heretofore been used in wet laid processing in conjunction with subsequent creping as disclosed in, for example, U.S. Patent 4,191,609 to Trokhan and U.S. Patent 4,125,659 to Klowak et al. In doing so the finally creped product exhibits greater softness, improved stretch and tensile strength, and enhanced bulk.
  • Patents 3,692,622 and 3,776,807 to Dunning and Dunning et al respectively disclose spot bonding of dry laid webs wherein 5 to 40% of the web surface is imprinted.
  • U.S. Patents 4,207,367 and 4,138,848 a plurality of highly compressed, narrow regions, preferably about 30% of the surface, separate the high loft regions, the high loft regions being bonded only partially.
  • the high degree of compaction enhances the absorbency rate and.wiping characteristics of said web without excessive reduction of product size, e.g., web roll diameter.
  • Another object of the invention is to provide bulky cellulosic web products, for example, tissue, towel and napkin products, having an enhanced rate of absorbency and improved wiping performance, each surface of which has received an imprinted pattern, the compacted area of each imprinted surface representing at least 40%, preferably 50%, of same.
  • a collateral object of.the present invention is to provide a method for the manufacture of the absorbent webs and web products of the present invention.
  • an air laid . bonded web is imprinted with a depressed design, preferably with a non-nesting pattern to avoid loss of final product roll diameter.
  • the bonded web to be imprinted is wetted optionally with a spray of water and subjected to an areal pressure of at least about 16 lbs./in 2 by platen means, said means having been heated to a temperature of between about 140 to about 180°C.
  • at least one surface of the treated web must have a compacted area of at least about 40% of the total imprinted surface area, prefereably between 50% to 80% of the total imprinted surface area. Each side of the web may be so imprinted.
  • the imprinting means is a pair of non-resilient clindrical rolls adapted for imprinting the web continuously. While the levels of compaction are analogous, the applied pressure is at least 100 lbs. per lineal inch. Again, the imprinting means are heated to 140 to 180°C., and a water spray is optional.
  • the diameter of individual product rolls or the composite thickness of packaged product sheets of the present invention are preferably reduced not more than 10% as compared to unimprinted products. Depending on the pressure applied by the imprinting means, said reduction may approach between 20 and 30%. However, the wiping absorbency of products of the present invention is increased by at least about 25%, preferably about 40% or more, as ascertained by relative values of mirror wipe time between imprinted and unimprinted products.
  • FIG. 1 a flow diagram of a process for making air laid webs, pulp sheets, laps or bales 10 are defiberized in defiberizer 11, here a hammermill, and transported pneumatically through line 12 to distributor 14 by blower 13.
  • defiberizer 11 here a hammermill
  • distributor 14 pneumatically through line 12 to distributor 14 by blower 13.
  • Distributor arrangements are well known in the art.
  • the individual fibers are dispersed onto an endless fourdrinier wire 15, which circles continuously about guide rolls 16.
  • Vacuum means 17 draws and retains the loose fibers 18 onto the wire 15 to form a loose web 19 which has little integrity.
  • the loose web 19 is typically pressed by consolidation rolls 21, which compaction increases web strength to a limited extent, and permits transfer of the pressed web 22 to a carrier wire 23.
  • Wire 23 has larger perforations than wire 15 and is made typically from a synthetic plastic material. The use of a separate wire 23, then, is less likely to cause plugging with bonding material 26 from spray dispensing means 27, and will improve clean up. As shown in FIG.
  • the once bonded web 29, partially dried in dryer 28, is transferred from carrier wire 23 to a second carrier wire 31 where a second spray means 33 dispenses additional bonding material 32 onto the second surface of the web. While two bonding applications are shown, one application will suffice where the web is porous and has a low basis weight, e.g., less than about 20 lbs. per 3000 sq. ft. ream. Additional information relating to a preferred process for bonding air laid webs is disclosed in commonly assigned U.S. Pat. Appl. S.N- 108,022 entitled “Methods of Applying Bonding Materials Onto Fibrous Webs", filed December 28, 1979 by Pauls et al. After each bonding application, the web is at least partially cured in dryers 28, 35. If complete drying is not achieved in dryer 35, a curing oven 40 is provided..
  • the bonded, cured web 39, and before take up on parent roll 41, is then imprinted at an imprinting station, here a pair of cylindrical rolls 42, although this location is not.critical.
  • station 42 can be situated between consolidation rolls 21 and bonding station 27, or between dryer 28 and bonding station 33.
  • the imprinting station may be located anywhere following the consolidation rolls 21. It should be noted that when the web is imprinted before the curing step, the compressive force applied by the imprinting means need not be as high as post curing imprinting because the pattern is less likely to "spring back".
  • station 42 may be included as a step in the converting operation '(not shown), either from parent rolls or individual product rolls.
  • This failing of prior art products is attributed to the.inherently large pore volume between fibers in air laid webs.
  • wet laid webs begin to bond as soon as they are laid.
  • the high moisture content of the wet laid web which decreases from about 99% per weight water beneath the head box to between about 65% to 85% just prior to consolidation, facilitates densification of the web.
  • the water "lubricates" the web and "plasticizes" the fibers so that the individual fibers can come into close physical relationship with one another.
  • Air laid webs do not have water to lubricate the fibers, resulting in less dense webs with greater bulk and larger interstitial void volumes. While bulk is highly advantageous, the consequences of excessively large void volume are not.
  • Compaction by the vacuum means 17 and the consolidation rolls 21 is not intended to highly densify the webs. Although it would be possible to increase the pressure of the consolidation rolls to highly compact the webs, the beneficial bulk provided by the air laid process would be lost. Furthermore, densification of the web by the consolidation rolls 21 would compromise the ability to disperse bonding agent 26, 32 through the web.
  • the invention disclosed herein can be used with air laid webs of between about 8 and about 60 lbs. per ream (3000 sq. ft.) basis weight which have been consolidated by rolls 21 with pressures of between 50 and 300 lbs./ lineal inch, and then bonded with a latex emulsion bonding agent, the bonding agent typically representing between about 10 to 30%, preferably between 15 and 25%, of the web basis weight.
  • a latex emulsion bonding agent typically representing between about 10 to 30%, preferably between 15 and 25%, of the web basis weight.
  • such webs have a bulk of between 0.7 to about 1.2 mils/lb./ream and a wet MD tensile strength of at least 200 gms. per 3 inch strip. Dry CD tensile is between 500 and 1500 gms. per 3 inch strip.
  • test is being used herein to determine gross differences in absorbency rate so that the standard deviations of individual measurements are neglible by comparison.
  • Caliper was measured with a Testing Machines, Inc. (Amityville, New York) Model 551M micrometer having a two inch anvil.
  • FIG. 3 and 4 are photomicrographs of a conventional uncompacted air laid web and a compacted air laid web, respectively, each enlarged 74 times.
  • the densified web of FIG. 4 has much smaller interstitial voids between fibers as compared to the uncompacted web.
  • capillary tension and wiping absorbency is increased in the web of FIG. 4 web as demonstrated by reduction in mirror wipe time. Note, however, that a significant loss in caliper occurs as a consequence of the compaction. This loss is more than about 80% in each instance.
  • a web 50 representative of the invention was prepared using a pair of etched plates each having raised areas representing 69% of the plate. That is, about 69% of each surface of the web was compacted.
  • the web so treated had a grid pattern illustrated in FIG. 2.
  • the compacted areas 51 were about 5/16 inch square (dimension x) and the non-compacted surfaces 52, e.g., the essentially uncompacted zones which appear as intersecting ribs or bridge regions, were about 1/16" wide (dimension y).
  • the depth of the compacted areas is dependent upon the pressure applied by the plates.
  • the uncompacted web (Table I) had a basis weight of 43 lbs./ream, and a caliper of 44.6 mils.
  • the imprinting of the web does not reduce the caliper of the non-compacted portions of the web, that is, dimension C 1 , remains about 44 mils. However, some reduction occurs, typically less than about 10%, but possibly approaching 20 to 30%. A compression load of about seven tons was applied between the plates for about 20 seconds.
  • the caliper C, of the imprinted web was measured as 31 mils with the Model 551M Micrometer, as compared to 44.6 mils for the uncompacted web and as compared to less than 9.04 mils for the compacted webs.
  • the loss in caliper is about 30% versus about at least 80% for the totally compacted webs.
  • Conversleyrelative to the wet laid web, the caliper of the imprinted web is about 30% greater.
  • Mirror wipe time for the imprinted web was measured at 17 seconds, which is an improvement of 46.9% over the - conventional dry laid web.
  • the actual pattern is not critical, it is essential that at least 40%, preferably more than 50%, of the area of one web surface be compacted. If both surfaces of web are compacted, each should be compacted to at least 40%, each preferably more than 50%.
  • the plates or cylinders are heated to between 140 and 180°C., with water sprayed on the towel before pressing. The spray of water is not critical to the process, but it does aid in retention of the compaction.
  • the grid pattern of FIG. 2 is not critical to the concept of improved web absorbency rate by high compaction imprinting, the grid pattern does affect the end product beneficially in that the grid pattern prevents nesting of the compacted zones within one another when the web is taken up on a product roll.
  • the roll of the invention web has essentially the same diameter as conventional products, which is preferred.
  • FIG. 6 illustrates an alternate embodiment of the web of the present invention. Although only one surface has received an imprinted pattern, both surfaces may be imprinted if desired.
  • web 60 has compacted area 61 and a plurality of non-compacted areas.
  • the web of FIG. 6 has contiguous compacted channel regions 61, which regions likewise represent at least 40% of the surface of the web so imprinted.
  • densified zones here indicated by numeral 63, exist beneath the compacted area 61. These contiguous channel regions are desirable because they provide pathways for lateral wicking.
  • Table I The data of Table I is reproduced graphically in FIG. 5.
  • This graph a plot of compacted web density versus Mirror Wipe Time, shows that the improvement in MWT is rapid until a density of about 0.35 g./cc. is achieved, which value corresponds to a compression force of about 15 lbs./in. 2 . Thereafter, MWT increases slightly, an asymptote being reached at about 0.80 g./cc. It is believed that analogous relationships between MWT and web density are applicable to the product of this invention.
  • the reduction in absorbency at the higher density values in FIG. 5 apparently occurs because the interstitial voids are too small to permit large amounts of water to be absorbed.
  • the preferred densities of the densified web region are between about 0.20 to about 0.50 g./cc., which would correspond roughly to MWT's below 14 and 13 seconds, respectively, for the webs of this invention. It should be noted that the optimal density of 0.35 g./cc. provides essentially equal abosrbency as compared to conventional wet laid webs, that is, an MWT of about 11.5 seconds.
