Definitions

  • PROCESS OF PREVENTING UNDESIRABLE LOOSENING OR MATTING IN PAPER FOR USE IN SANITARY PRODUCTS AND THE PRODUCTS THEREOF Filed Aug. 17, 1966 1 ENTORS KENNETH ClHoKAusow and DONALD KGE-OEGE' ATroRNEys United States Patent ()fiice dfildfidd Patented Feb. 27, 1968 3,370,599 PROCESS F PREVENTING UNDESIRABLE LGQSENING 0R MATTING IN PAPER FOR USE IN SANITARY PRODUCTS AND THE PRODUCTS THEREOF Kenneth C. Hokanson and Donald K.
  • the process comprises impregnating a Wet Web of the sheet material during manufacture thereof and while the web contains a substantial amount of moisture of at least 60% with a high molecular weight water soluble polymer that enhances bonding of the fibers of the finished sheet without adversely affecting the dispersible properties so that it is resistant to loosening or matting of the fibers during normal use.
  • This invention relates to a novel process for preventing undesirable loosening and matting on the surface of paper products when subjected to friction. More particularly, the invention relates to the utilization of this process in the manufacture of a special type of paper for use in diapers, sanitary napkins, bandages, nursing pads, etc., which are collectively designated hereinafter as Sanitary Products.” Loosening and matting of fibers on the surface of such products, as they become moistened with body fluids during use, causes these fibers to stick to the body of the wearer, and more particularly in the case of sanitary napkins to entangle in the pubic hair of the wearer, resulting in discomfort and unsightly appearance. The process of the present invention overcomes this problem.
  • Those products are characterized by having the necessary strength to prevent disintegration or damage during normal use, the necessary high water asborbency and other physical properties when in use, and finally the property of disintegrating quickly and easily when agitated in a large excess of water, such as in a water closet, whereby they may be easily flushed away without danger of clogging the fixture.
  • Patent No. 3,171,773 constituted a marked advance over prior so-called disposable products which were not truly flushable in the ordinary water closet Without clogging the fixture.
  • the products disclosed in the above Patent No. 3,171,773 were composed entirely or predominantly of a material made from a special form of regenerated cellulose fibers. These fibers are disclosed in U.S. Patent No. 3,156,605, issued Nov. 10, 1964, as hydrophilic, fiat, ribbon-like, aerated, re-
  • the material made from these special fibers has relatively good dry strength, good wet hang and dispersibility properties that are required to produce the satisfactory flushable product covered by said Patent No. 3,- 171,773.
  • Reference to this Patent No. 3,171,773 may be had for a further more detailed description of the special fibers and their properties.
  • An important feature of the present invention is to eliminate or avoid the above described loosening and matting characteristic of the material made from the above special fibers, without adversely affecting the important properties of high dry strength and ease of dispersibility, above described, that renders the products truly fiushable.
  • FIGURE 1 is a reduced perspective View of a sanitary napkin utilizing the improved paper of this invention.
  • FIGURE 2 is a reduced perspective view of a diaper pad utilizing the improved paper of this invention and illlustrated as being held in a holder for application to a baby.
  • the special regenerated cellulosic fibers of the Patent No. 3,156,605 may be so treated during the process of manufacture of a paper sheet comprising these fibers, to eliminate the tendency of the fibers in said paper to loosen or mat when subjected to friction or slight abrasion.
  • This process comprises in essence a novel treatment of the paper web during its manufacture on the paper machine such as, for example, a Fourdrinier paper machine as disclosed in G. L. Bedwell Patent No. 2,488,- 700, issued Nov. 22, 1949.
  • the treating process comprises applying to the wet paper web a certain chemical or chemicals which have been found elfective for the purpose of this invention and described further below.
  • the chemicals which are added to the wet paper web are not for the purpose of effecting flushability of the paper products produced from the ultimate paper sheet because the paper made from the fibers of the above patent already possesses that property, but instead serve the purpose of preventing the fibers of the paper products from loosening or matting and this without adversely affecting the flushability of the product.
  • the suitable chemicals for accomplishing the abovedescribed purpose of the present invention fall within the class of high molecular weight Water soluble polymers and illustrative, but non-limiting, specific examples of same are methylcellulose, ethylcellulose, gelatin, soluble starches, dextrin, water soluble gums, polyvinyl alcohol and polyvinylpyrrolidone, preferably of as high solution viscosity as possible but allowing a dilute solution of the chemical to be sprayed on the wet web.
  • the amount of chemical to be added to the paper may vary substantially but in actual practice it has been found that amounts of about 0.2% to based on the weight of the dry paper, may be used. A typical amount which has been found to give very good results is 2%.
  • These chemicals have the property of increasing the cohesiveness or bonding together of the fibers of the cellulosic sheet material so that in the normal use of the end products, the fibers of the paper material will not loosen or mat to any appreciable extent. This is in marked contrast to the products produced from material using the same fibers without the benefit of the process of the present invention and which have been found to loosen or mat quite considerably during normal use.
  • the chemical or chemicals used in the process of the present invention may be applied to the wet paper sheet, as above described, by spraying, dipping, immersing, kiss roll application, or other conventional means and methods, preferably by spraying.
  • the cellulosic web or paper sheet produced in accordance with the present invention may be used in whole or in part in a variety of ways in the manufacture of the sanitary products above described or for other similar products which may be worn in contact with the human skin.
  • the improved sheet material in commercial manufacture of sanitary products utilizing the cellulosic fibrous sheet material of this invention, it has been found particularly desirable to use the improved sheet material as a wrapper or cover material for enclosing and holding therein an interior pad of dispersible fibrous absorbent material which is adapted to absorb the bulk of the body fluids of the wearer.
  • This interior pad may comprise an improved fluffed wood pulp, as disclosed in copending application, Ser. No. 593,004, filed Nov. 9, 1966, assigned to the same assignee as the present invention, in cut layers, folded layers, shaped masses, etc., with or without creped wadding or creped tissue folded or formed therewith.
  • the improved fibrous cellulosic sheet material of this invention is used as a wrapper or cover material in combination with a cheaper interior pad of dispersible fibrous adsorbent.
  • the overall cost of the sanitary products may be substantially decreased.
  • the improved material would be utilized as a wrapper or cover for completely enclosing a layered, folded or otherwise formed pad 12 of improved dispersible fibrous absorbent material, as more particularly described in the above copending application.
  • This wrapper or cover would be manufactured in the usual configuration and secured around the pad to form attachment tabs on either side of the interior pad for attachment to the normal belt or holding means when utilized by the wearer.
  • the improved cellulosic fibrous sheet material of this invention would be utilized as a wrapper or cover for enclosing a bulky absorbent dispersible fibrous pad 22, the wrapper or cover material being formed into the desired generally rectangular configuration and secured around the pad for use as a diaper pad to be inserted within a holder 24 for placing in position on the body of the wearer.
  • the pad 22 is preferably formed of the improved fluffed wood pulp of the above copending application and reference may be had thereto for specific details of the pad construction.
  • pregnating chemical is selected from the group consisting of methylcellulose, ethylcellulose, gelatin, soluble starches, dextrin, water soluble gums, polyvinyl alcohol and polyvinylpyrrolidone.
  • a flushable sanitary product comprising:
  • a flushable sanitary product as defined in claim 5 in which said product is a sanitary napkin.
  • a flushable sanitary product as set forth in claim 5, in which said sanitary product is a diaper pad.
  • a cellulosic fibrous sheet material which is resistant to loosening or matting of the fibers and which has high dry strength, wet hang and dispersibility when agitated in a large excess f Wa e said material comprising:
