Definitions

  • Cores are a paper or paperboard construction around which material is wound.
  • the material can be tissue or towel, carpet, textile, plastic film, paper or any other material that is would around a core.
  • a tube is a container that is used to transport or store various dry foods, refrigerated foods or dough, oils and other liquids; and is also used for various other industrial applications.
  • Cores or tubes can be made using single or multiple plies of substrates.
  • Top speed capability the amount of time required to go from initial start up to full speed, scrap rate, and the quality of finished cores and tubes are all affected by the adhesive chosen.
  • Convolute winding uses a web of paper that is as wide as the resulting core is long. A mandrel spins and winds the paper onto itself forming the core. The adhesive is continuously applied to the ply material as the core is wound.
  • Spiral winding comprises continuous winding of 2 or more plies around a mandrel at an angle causing the length of the core to grow as the plies are wound.
  • the adhesive is continuously applied to the ply material as the core or tube is wound.
  • Aqueous adhesives and aqueous foamed adhesives, are known to be useful for adhering paper.
  • Aqueous adhesives are also used in paper core manufacture, however the aqueous nature of the adhesive in this application presents numerous problems.
  • Water based adhesives must dissipate water before a bond can be formed.
  • the water dissipates due to evaporation and/or absorption into the substrates (plies), and in the process the adhesive becomes tacky. Therefore an adhesive with the least amount of water is the most desired.
  • a water based adhesive must comprise enough water so when applied, the adhesive is sufficiently wet at the time of contact to ensure that both plies, that are to be bonded together, are wetted by the adhesive. This dichotomy, of the adhesive being wet enough to affect the surfaces of the plies, but not too wet such that the bond takes a long time to form, raises concerns for the core and tube construction industry.
  • dog ears refers to ply separation during the core cutting stage; the ply typically folds back upon itself resembling a dog's ear.
  • the absorptive characteristics of the ply material also have a significant impact on the adhesive performance when aqueous adhesives are used. If the ply material is too absorbent, the adhesive penetrates the ply material and precures (becomes dry) before the ply is wound on the mandrel. If the ply material is made of an nonabsorbent material, the coated ply is likely to be too wet when it comes in contact with another ply, thus causing slippage.
  • foamed adhesives do not penetrate porous surfaces to the same extent as nonfoamed adhesives and therefore open time increases and the tendency to precure decreases.
  • a foamed adhesive contains less water than an unfoamed adhesive. With less water to dissipate, a bond forms more quickly upon compression reducing the possibility of ply slippage and/or "dog ears". Also, the possibility of producing soft and/or soggy cores or tubes is reduced.
  • the foamed adhesives of the present invention allow tube/core manufacturers to use less adhesive and therefore add less moisture to the core construction.
  • the reduced adhesive content per a given volume allows high speeds to be obtained without adjustments to application amount.
  • these adhesives will not permeate the surface of a substrate, therefore allowing acceptable core/tube production.
  • foaming waterbased adhesives provides an unexpected benefit in the construction of paper cores or tubes.
  • the present invention is directed to adhesives formulated with up to 40% foam by weight added and the use of these adhesives in paper cores and tubes.
  • the present invention is directed to aqueous adhesives formulated with up to 40% by weight foam for use in paper cores and tubes.
  • the present invention is also directed to a method of making paper cores and tubes using a foamed adhesive.
  • the adhesives of the present invention include any conventional aqueous adhesive usable for paper core/tube manufacture.
  • adhesives that may be foamed include polyvinylacetate homopolymer or copolymer emulsions (neat or formulated with other components), polyvinyl alcohol, dextrins, starches, acrylates, silicates, filled systems and crosslinkables.
  • Preferred are the formulated polyvinyl acetate homopolymer emulsions.
  • a standard polyvinylacetate-based adhesive would not generate consistent foam until the defoamer component was substantially reduced or totally removed from the formula. Since defoamers are typically compounded into the adhesive formulation, adhesive formulated for the present invention should not have any defoamer, or at the minimum as reduced amount.
  • foaming agents such as surfactant or soaps
  • foaming agents such as surfactant or soaps
  • removal of defoamers and/or adding wetting agents from adhesives can be by methods familiar to one of ordinary skill in the art.
  • foamed adhesives of the present invention up to 40% by weight foam is added to the conventional adhesive.
  • Foam may be added to the adhesive by methods familiar to one of skill in the art, including mechanical stirring or agitation, introduction of gases, or by chemical reactions. Gases that may be used to introduce foam include air, nitrogen or oxygen.
  • the preferred method of introducing foam into the adhesives of the present invention is via mechanical agitation in situ with gas introduction.
  • the foamed adhesives of the present invention are applied during the conventional corewinding or tubewinding process used to manufacture paper cores or tubes. Specifically, the foamed adhesives are used in place of conventional adhesives in a conventional corewinding process.
  • a paper core or tube comprising one or more plies of paper or paperboard are bonded together with an adhesive which has been foamed to 40% by weight.
  • the foamed adhesives of the present invention contain less water by volume than unfoamed adhesives.
  • the volume of the adhesive increases allowing less adhesive to be used resulting in faster drying times, a reduction in the amount of adhesive used, and a reduced cure time for the finished core of tube construction.
  • Water in the waterborne adhesive swells the paper fiber in the core or tube construction. As the freshly made core/tube dissipates the water it normally shrinks from its original dimension. As a result, many core/tube processes include a built in "cure time" prior to cutting the construction to its final dimension. The use of the adhesives of the present invention, reduce the dimension change of the final core or tube and minimize the cure time.
  • foamed adhesives of the present invention do not penetrate porous surfaces to the same extent as nonfoamed adhesives. This increases open time and decreases the tendency of the adhesive to precure prior to contact with the addition plies. Further, since the foamed adhesive contains less water by volume than an unfoamed adhesive, there is less water to dissipate, and the bond between the plies forms more quickly reducing the possibility of ply slippage and/or "dog ears". Also, this reduction in the amount of water prevents the production of wet or soggy cores/tubes, which when filled or subjected to further processing, may come apart. In addition, the foamed adhesives of the present invention allow a much wider operating window of adhesive application amount during changes in production speed. Typically, the production speed of corewinding equipment cannot change without adjustments to the amount of adhesive applied. By using the foamed adhesives of the present invention, corewinding equipment can be run up to 100% maximum line speed with no adjustments to application amount.
  • the corewinding machine had a maximum speed of 350 core FPM (100%).
  • the glue roll to doctor blade gap was 0.012".
  • the adhesive formulations were foamed with air using a foam generator Model 2MT available from E. T. Oaks Corporation.
  • ethylene vinyl acetate based adhesive was evaluated; the control was pure adhesive which was compared to a sample foamed to 20% and 40% air by weight.
  • the adhesive comprised 92% EVA, 4.5% polyvinyl alcohol, and 3.5% water. This adhesive was a high solids, fast setting formula with a viscosity of 1500 cPs. The following was observed:
  • EXAMPLE 3 A polyvinyl acetate emulsion with a viscosity of 1500 cPs and available under the tradename PRODUCER® from National Starch and Chemical Company was evaluated; the control was pure adhesive which was compared to a sample foamed to 40% air.
