Definitions

  • ABSTRACT An impregnated paper product having strength, toughness, tear resistance, softness, hand and breathability sufficient to permit such papers to be used as substitutes for woven or non-woven fabrics in making disposable fabric products.
  • This invention relates to paper, and more particularly, is directed to improved paper products useful as a substitute for woven and non-woven fabrics.
  • paper and paper-like products for woven and non-woven fabrics would be ideal for the making of disposable products, but paper, in general, has had several serious drawbacks from the standpoint of physical characteristics. While paper can be made from very inexpensive wood pulp fibers at a very high rate of speed, such papers that might be suitable as a substitute for fabrics such as creped or uncreped tissues or waddings suffer from an inherent lack of strength and toughness, particularly in the cross direction.
  • tear resistance and tensile strength can be imparted to papers by the addition of other materials such as styrene-butadiene polymers, methyl-methacrylates, urea formaldehyde and melamine resins, etc.
  • other materials such as styrene-butadiene polymers, methyl-methacrylates, urea formaldehyde and melamine resins, etc.
  • the strength and tear resistance may be increased to acceptable levels, but the papers do not have the desirable characteristics of hand, drape, softness and breathability inherent in woven fabrics.
  • Some degree of softness can be imparted to resin impregnated papers by the addition of glycerin or polyethylene glycol softeners to the paper. But, even in such instances, the hand, drape and breathability have been so inferior as to prevent the use of resin or polymer strengthened papers as a substitute for woven or non-woven fabrics.
  • FIG. 1 is a schematic flow diagram showing one method of making the paper products of the present invention.
  • FIG. 2 is a schematic flow diagram showing another method of making the paper products of the present invention.
  • the first mentioned tubbing" or impregnation method is required since at least two preformed dry creped tissue sheets must be first superimposed before being subjected to treatment with the resin emulsion. After the preformed sheets have been superimposed they are then passed through the emulsion of the particular strength imparting resin employed.
  • the resin concentration of the emulsion and the speed with which the paper is passed through the emulsion is controlled within limits to give the desired tensile strength and tear resistance characteristics as set forth more fully hereafter.
  • the unique paper products of the present invention are shown being made by first superimposing two webs, 10 and 12, of dry creped tissue or wadding being delivered from supply rolls l4 and 16, respectively.
  • the superimposed webs 10 and 12 then pass over a driven vacuum roll 18 which is provided in the usual manner to control tension in the web.
  • An idler roll 19 is provided to change direction of the web prior to its passing over a spreader roll 20.
  • the spreader roll 20 is a conventional Mount Hope" type and is used to maintain the combined web 10 and 12 at its maximum width and wrinkle free.
  • the combined web 10 and 12 is passed into a nip 22 existent between a pair of superimposed, rotating squeeze rolls 24 and 26, the latter of which is positioned with a portion of its lower half in vat 28 containing an aqueous emulsion or suspension 30 of the resins or polymeric substances to be impregnated into the web.
  • squeeze roll 26 picks up on its surface the resin or polymer suspension 30 and carries it into the nip 22 where the webs l0 and 12 become saturated with the suspension by impregnation.
  • Rolls 24 and 26 are normally biased together to exert a squeezing pressure on the webs l0 and 12 at the nip 22 to squeeze out and remove any excess of the resin or polymer suspension from the web.
  • the webs l0 and 12 are a dry creped tissue or wadding (i.e., the crepe has been imparted thereto while the paper is in a dry state whereby the fiber to fiber bonds have been formed therein while in the uncreped wet state prior to creping), passing through the aqueous suspension 30 readily causes the crepe to be removed therefrom, thus forming an uncreped, overall resin bonded laminate.
  • vacuum roll 18 mentioned earlier is driven at an angular velocity slightly under the angular velocity of the squeeze rolls 24 and 26 thereby imparting sufficient tension in the webs l0 and 12 to add a mechanical force for the removal of the crepe.
  • the resin emulsion or suspension is impregnated into the superimposed dry creped webs by passing them directly into the vat containing the aqueous suspension or emulsion.
  • the webs 50 and 52 of dry creped tissue or wadding are delivered separately from supply rolls 54 and 56 respectively into superimposed relationship over and under respectively a pair of idler rolls 58 and 59.
  • the superimposed webs 50 and 52 are then passed under the lower roll 66 of a pair of superimposed squeeze rolls 64 and 66, which lower roll 66 is positioned in a vat 68 with a portion of its lower half immersed in the aqueous resin or polymeric suspension or emulsion 70 contained therein.
  • the combined webs 50 and 52 then follow around the lower roll 66 passing through the nip 60 defined between rolls 64 and 66 where the excess emulsion or suspension picked up by the web is squeezed out.
  • the impregnated and saturated web passes through the conventional hot-air tunnel 32 and the series of heated can driers 34 to remove excess water and to cure the resin or polymeric materials in precisely the same manner as shown and described with respect to the method depicted in FIG. 1.
  • the resin bonded, uncreped laminate 36 is also then rewound into rolls 38 ready for use in fabric-like products.
  • the crepe present in the dry creped webs 50 and 52 is readily removed when the combined webs pass into the aqueous emulsion or suspension 70 in the vat 68, thus assuring overall resin bonding between the webs in the uncreped laminate ultimately produced.
  • the papers used as the starting materials for making the products of the present invention are of the class known as dry creped wadding or tissues which are of a porous character having a thickness ranging from about 2 mils to about 20 mils.
  • Their basis weight can be from about 5 pounds up to about 30 pounds which means the weight in pounds of a standard ream (3,000 square feet) of paper. Most preferred is a basis weight of about 10 pounds.
  • the wadding used can have a crepe based stretch level in the machine direction ranging from about 5 to about 50 percent and most preferred is a stretch level of about 15 percent, and an inter-fiber stretch level in the cross direction ranging from about 2.3 percent to about 6 percent and most preferred is a stretch level of about 4.5 percent.
  • the combined web will have a total basis weight ranging from about 10 pounds to about 60 pounds and most preferably about 30 pounds. Its machine direction stretch level due to creping will remain substantially unchanged from the individual plies as will the cross-direction stretch level due to inter-fiber bonding.
  • the saturation bath in general will be made up of an aqueous suspension or emulsion containing from about 5 to about 50 percent resin or polymer solids and preferably about percent solids.
  • the particular resins or polymers used or mixtures thereof can be any and all of those well known in the paper making art as strength imparting additives;
  • the superimposed dry creped webs are delivered together to the aqueous emulsion or suspension of resins or polymeric materials at a controlled rate of speed to provide a dwell time in the suspension sufficient to obtain a wet pick-up of the suspension or emulsion ranging from about 75 percent to about 250 percent based upon the weight of the combined superimposed webs. Most preferred is a wet pick-up of about 150 percent of the suspension or emulsion.
  • the wet pick-up is further controlled by adjusting the biasing force between the squeeze rolls where any excess pickup of the emulsion or suspension is pressed out of the webs.
  • the saturated webs are dried at 240F 350F for about 2 minutes to remove the water from the webs and to cure the resins or polymers in their water insoluble state.
  • Such treatment results in a lightweight, resin bonded, uncreped paper laminate containing from about 10 percent to about 30 percent resin and most preferred, about percent of resin or polymer solids based upon the weight of the dry resin bonded laminate.
  • the resin. bonded uncreped paper laminate thus formed exhibits substantially equal stretch levels in both the machine and cross directions, and since the crepe has been removed, the stretch exhibited by the laminate is due solely to the internal resinfiber bonding relationship.
  • the resin bonded, uncreped laminate produced exhibits an internal resin or polymer-fiber stretch level in both the machine and cross directions ranging from about 8 to about 20 percent and most preferred is a stretch level of about 13 percent.
  • the paper product of the present invention even though containing hardening water-insoluble resins, has excellent softness, hand, drape and breathability.
  • Softeners such as glycerin or polyethylene glycols are not required when practicing the present invention to produce a suitable paper substitute for woven and nonwoven fabrics, but they may be included where it is desired to produce a paper product having a very high degree of softness.
  • softeners When such conventional softeners are used, they are added to the saturation emulsion or sus ension alon with the resin or 0] mer solids. If use Medicare at all, the b ath will contain no r nor e than 25 percent of the glycerin or polyethylene glycols. But it is emphasized, softeners are not required in most instances to make the unique resin bonded, uncreped paper laminate of the present invention.
  • An uncreped laminated paper product suitable as a substitute for woven and dry-laid non-woven fabrics comprising at least two plies of lightweight, dry creped tissue, said laminate having impregnated therein a uniformly distributed strength imparting polymeric resin by which said dry creped tissue plies are overall bonded together with the crepe being removed to the extent that said uncreped laminate has a stretch level due solely to the internal resin-fiber bonding relationship, said stretch level in both the machine and cross direction ranging from about 8 to about 20 percent.
  • each of said plies of dry creped tissue has a basic weight ranging from about 5 pounds up to about 30 pounds, a crepe-based stretch level in the machine direction ranging from about 5 percent to about 50 percent and an inter-fiber stretch level in the cross directions ranging from about 2.3 percent to about 6 percent prior to impregnation with said polymeric resin.
  • each of said plies of dry creped tissue has a basis weight of about 10 pounds, a crepe based stretch level in the machine direction of about 15 percent and an inter-fiber stretch level in the cross direction of about 4.5 percent prior to impregnation with said polymeric resin and the removal of the crepe therefrom and said laminate has a resin-fiber based stretch level in both the machine and cross directions of about 13 percent.
