Definitions

  • The'web of toweling may be composed of, say,
  • the web may be passed through an aqueous glue solution whose glue content corresponds with that desired in the finished toweling.
  • aqueous glue solution whose glue content corresponds with that desired in the finished toweling.
  • I may pass the web through an impregnating solution containing up to about 5% glue solids and preferably containing up to about /2% of a tanning agent such as formaldehyde, alum, or tannic acid.
  • the solution-soaked web is then passed through squeeze rolls which may be adjusted to reduce the solution content of the web to a point where the web holds similar to those used at the dry end of the usual paper'machine.
  • the dry toweling is characterized by an remarkably enhanced wet strength and a water absorptivity practically similar to that of the waterleaf paper used as a raw material.
  • the finished toweling containing only about 3% tanned glue, based on the weight of dry fiber may be characterized by a wet strength about four to seven times as great as that of the waterleaf paper used as the starting material. 4
  • the web of toweling may undergo such operations as ereping and/or embossing in the course of its manufacture, which operations are well known in paper towel manufacture.
  • the dried, glue-impregnated web may be mechanlcal- 1y softened, as by being brought into facial engagement, while under tension with the edge of a so-called doctor blade.
  • the softness and limpness of the web may also be enhanced by adding a softening agent, such as glycerine, soap, and alcohol, in relatively small amount to the glue solution.
  • the glue solution may contain a small amount of suitable preservatives. for instance phenolic compounds of the type of sodium-ortho-phenyl-phenate, which permit the glue solution to stand for comparatively long periods without putrefaction.
  • the glue used as a raw material may be derived from various sources, such as bones, fish, or hides.
  • the usual glues of commerce including those which have heretofore sometimes been used in sizing papers, may serve as the raw material.
  • any of the glues on the market glues which have been chemically treated or purified so as to be more valuable for use in paper toweling, and glues which upon drying become substantially water-insoluble, may be selected for the purpose of my invention.
  • the glue even when it is set in substantially water-insoluble condition, is apparently very easily wetted by water, by which I mean that water spreads easily over the films or coatings of glue rather than being shed therefrom.
  • the glue Inasmuch as the glue is distributed throughout the web and is present in such small amount that a large overall glue surface is exposed to contact with water without material loss in the total volume of the pores, the web of necessity must have a large capacity for water absorption. Doubtless, too, in addition to being wetted by water, the glue adsorbs and/orabsorbs the water 7 and then transmits water to the cellulose fibers, which, of course, are also capable of absorbing large amounts of water.
  • the sized pulp was then run off on a papermaking machine.
  • a pre-sized and dried paper sheet is sometimes passed through a bath of sizing agent, such as a glue or starch solution, and redried.
  • the second or surface-sizing treatment more perfectly fills the surface pores of the paper. All the paper-sizing procedures of the prior art, including the sizing of paper with glue, were thus carried out so as to produce papers of low waterabsorptivity.
  • a method which comprises dipping a porous, waterleaf web of paper into a glue solution containing less than 5% by weight of glue solids and containing a tanning agent for said glue to effect a soaking of such web with the solution,
  • the method of preparing a soft flexible, porous sheet of paper which comprises impregnating a sheet of thin paper of open formation with a dilute solution of albuminous adhesive, removing a part of the solution to reopen the interstices of the paper while leaving a thin coating of adhesive on the fibers to bind them together at their junctions, and rendering said coating temporarily water resistant, whereby the resulting sheet is characterized by softness, flexibility, porosit and high wet strength.
