Definitions

  • This invention relates to detergent impregnated fibrous structures for the cleansing of dishes and other articles.
  • the cleansing substance may be either soap or a non-soap detergent surfactant composition.
  • the non-soap surfactant compositions have been found generally more effective on the greasy food soils associated with dishes.
  • Sponges and brushes of various types have also been used to perform the scrubbing function, although a dishcloth is customarily employed. This mechanical action aids the cleansing process by mechanically agitating the food and grease particles clinging to the dishes and by carrying the soap or detergent solution to the dish surfaces.
  • the dishcloth agitates the water solution of soap or detergent so that loosened grease and soil particles are emulsified or otherwise put into solution or suspension by action of the cleansing substance.
  • the disadvantage of the procedure outlined above is that it is accomplished by a more or less inexact addition of amounts of cleansing substance to the water and is culminated by the necessity of storing a wet dishcloth or other spongious body between dishwashing operations.
  • the housewife In addition to the problem of where to hang the dishcloth for drying, the housewife is confronted with either the inconvenience of meticulously cleansing the dishcloth, itself, after each use, or the liability of incurring a kitchen nuisance problem.
  • This nuisance problem is made up of the mildew, odors and other products of bacterial or fungal action associated with damp porous bodies containing organic material.
  • Various means have been suggested or employed in an attempt to eliminate the nuisance of a dishcloth and to improve the exactitude with which amounts of detergents are added to batches of soiled dishes.

  • plastisol refers to plastic formulations which contain, in addition to powdered thermoplastic resins and liquid plasticizers, minor amounts of a compatible release agent. Because of the addition of release agents, the preferred plastisol formulations are readily printable and may be proper members of the organosol class.
  • Another object of this invention is to provide a disposable, uniformly detergent-loaded paper dishcloth of laminated paper construction having substantially the sarne wet-handlin g characteristics asa non-disposable dishcloth.
  • a still further object of this invention is to provide a laminated, wet-strength, paper structure, at least one ply of which is uniformly impregnated with effective amounts of a non-soap detergent surfactant, whose plies are held together by a continuous open-grid pattern composed of a bonding agent which contributes wet-bursting and wettearing strength to the structure without substantially interfering with the lateral or vertical movement of liquids within the individual plies of the laminate.

  • the plies of the present dishcloth may be formed of wet-creped, dry-creped and uncreped wet-strength toweling papers and combinations thereof, the creped papers are preferred because of the resiliency, absorbency and surface characteristics which they contribute.

  • a printing system known as intaglio, wherein pigmented bonding materials are-deposited from grooves in a roller has been found preferable in the present laminate formulation, but any system capable of placing the plastisol in the required pattern is acceptable for use in forming the paper structure.
  • These systems include, for example, offset printing and extrusion of the plastisol thru orifices.
  • the base sheet having the open-grid pattern of bonding plastisol applied thereon, is then brought into contact with another sheet on the still tacky printed side so that a bond is formed between the two sheets with the continuous bonding pattern sandwiched between the plies.

  • the time and temperature necessary to fuse and bend a given thermoplastic formulation without causing it'to slump can be easily determined by those skilled in the art. It is important to fuse and bond the thermoplastic without the application of exces- 's'ive heat because, if the plastic runs, ply separation will For instance, the machine dibe lessened.
  • Plastic fluidity caused by excessivee'heat will also permit penetration of the thermoplastic into or thru the paper at the bonding lines, and is to be avoided so that the absorbency of the plies at these points is substantially undiminished.
  • maximum grid strengths are obtained at longer curing times; for example, 350 F. for a period of about 5 minutes to about 10 minutes. Higher temperatures can also be employed for shorter periods to avoid charring the paper plies.
  • the heat necessary to accomplish the fusion of the powdered thermoplastic in the plastisol pattern and its bonding to the outermost fibers of the paper can be applied in any convenient manner.
  • the laminate can be passed thru a zone heated by electrical resistance elements, steam coils, infrared lamps or dielectric heating.
  • the laminate passes from the heated zone to a relatively cooler zone, which may be at room temperature or may consist of a cooled zone in a higher speed process.
  • This cooled zone solidifies the thermoplastic in its fused form.
  • One or both of the outside plies of the laminate are then impregnated or coated by spraying, dipping, doctoring, orifice or roller techniques, with aqueous or solvent solutions of detergent solids so that the detergent solids are absorbed in one or more plies of the laminate. If desired, the treated laminate can be passed between rolls to further distribute the detergent.
