Definitions

  • the present invention relates to a process for coating a material of the type as defined in the preamble of claim 1 and to a coated substrate of the type as described in the preamble of claim 10.
  • a process for coating a material and a coated substrate of this type are disclosed in GB-A-941 073.
  • This publication describes a process and several apparatus for impregnating fibrous webs with solutions or the like. No specific solution and no specific concentration thereof are described.
  • the fibrous web is impregnated with the solution by applying the solution to a first roll and then passing the fibrous web supported on a continuous band of wire mesh through a nip formed between this first roll and a second roll, while the wire mesh contacts the first roll.
  • the impregnating solution will be uniformly applied to the interstices of the wire mesh band and will thereafter be transferred to the fibrous web.
  • Nonwoven, hydrophobic substrates or materials are well known in the art. Many disposable products such as diapers and sanitary napkins are constructed with top sheets made of nonwoven, hydrophobic material. The outer surface of these top sheets is typically treated with a wetting agent to allow fluid to more readily penetrate the outer surface for capture by an underlying absorbent pad. Top sheets made with a hydrophobic material having an outer surface treated with a wetting agent are preferred for such applications over top sheets made with a hydrophilic material because the wetting agent provides hydrophilic properties to the outer surface to improve fluid penetration without compromising the desired hydrophobic properties of the inner surface of the top sheet. The hydrophobic inner surface retains the penetrated fluid and inhibits flow back of the penetrated fluid to the outer surface, thus acting as a "one-way valve".
  • wetting agent it is desired to apply the wetting agent to the nonwoven material in a uniform concentration for aesthetics and to provide uniform wettability to the outer material.
  • Nonwoven materials typically have irregular surfaces onto which it is difficult to uniformly apply the wetting agent. This is particularly so if a coating solution having a high concentration of wetting agent is used.
  • wetting agents are typically applied by spraying, direct printing, or roller coating a low concentration solution of the wetting agent onto the outer surface of the material.
  • a material treated using conventional techniques is disclosed in US-A- 4,585,449 to Karami.
  • the present invention fills the above need by providing a process for uniformly applying a high concentration solution of a wetting agent to a fibrous substrate such as a nonwoven material in accordance with the features of claim 1.
  • the application of a high concentration solution results in lower wet pick-up by the material, which reduces subsequent drying of the material and the associated loss in tensile strength. This provides a strong, nonwoven material having a uniform coating.
  • the present invention provides a process for coating a material, the process comprising the steps of introducing a coating solution to a first rotating roll, the coating solution containing between about 20 and 30 percent by weight of a wetting agent compound and between about 70 and 80 percent by weight of a solvent; and passing the material through a nip defined between the first roll and a second rotating roll positioned adjacent the first roll, wherein a portion of the coating solution is applied by the first roll to a surface of the material in an amount such that the wetting agent is applied to the material in an amount of between about 0.1 and 0.5 percent by weight of the material, and the solvent is applied to the material in an amount not exceeding about 1 percent by weight of the material.
  • Another aspect of the present invention provides a coated substrate, comprising a nonwoven material and a substantially uniform coating on a surface of the nonwoven material.
  • the coating comprises a wetting agent applied to the nonwoven material in an amount of between about 0.1 and 0.5 percent by weight of the nonwoven material and a solvent applied to said nonwoven material in an amount not exceeding about 1 percent by weight of said material.
  • a further object of the present invention is to provide a process for coating a fibrous material using a high concentration coating solution such that wet pick-up and loss of tensile strength are reduced and drying requirements are reduced and may be eliminated.
  • a still further object of the present invention is to provide a process for coating a fibrous material which does not require drying of the coated material and yet microbiological testing confirms that no unacceptable levels of bacteria are present.
  • Figure 1 is a perspective drawing of the "inverted L" differential offset printer used to apply a coating to a material in accordance with the present invention.
  • Figure 2 is a graph showing the percent surface concentration of the wetting agent on the coated material of the present invention as a function of cross-direction position.
  • Figure 3 is a graph showing the percent surface concentration of the wetting agent on the coated material of the present invention as a function of machine-direction position.
  • Figure 4 is a graph showing the percent surface concentration of the wetting agent on the coated material of the present invention as a function of gravure roll speed.
  • the nonwoven material 18 is preferably a hydrophobic, nonwoven spunbonded web having a basis weight of between about 16,9 and 33,9 g/m 2 (0.5 and 1.0 ounces per square yard- "osy") although the basis weight is not known to be critical and may be higher, for example, up to 84,8 g/m 2 (2.5 osy) depending on the desired application.
  • basis weight is not known to be critical and may be higher, for example, up to 84,8 g/m 2 (2.5 osy) depending on the desired application.
  • Such material is well known in the art and may be prepared in conventional fashion such as illustrated by the following patents: Dorscher et al.
  • the wetting agent 14 is applied to a surface 50 of the nonwoven material 18 using the printer 10 to provide hydrophilic properties to the surface 50.
  • the printer 10 is preferably a "differential” type printer, with the term “differential” referring to printers wherein the gravure roll speed may be varied with respect to the material or line speed to allow compensation for basis weight changes without changing the gravure roll.
  • the most preferred printer is that which is referred to in the art as an "inverted L" differential offset printer, such as is shown in Fig. 1.
  • the wetting agent 14 is preferably a non-ionic surfactant.
  • a preferred wetting agent for use with nonwoven materials having a basis weight up to about 27,2 g/m 2 (0.8 osy) is "Triton X-102," available from Union Carbide. "Gemtex SM-33", available from Finetex Inc. is a preferred wetting agent for use with nonwoven materials having a basis weight in excess of about 27,1 g/m 2 (0.8 osy), particularly where "one-way valve" properties are not necessary.
  • a surface concentration of the wetting agent on the material of between about 0.1 percent to 0.5 percent, broadly and, preferably, between about 0.16 percent and 0.38 percent is desired.
  • the "fountainless pan” doctor blade system 44 supplies a uniform application of a solution containing the wetting agent 14 to the gravure roll 38 in a conventional manner.
  • the solution is preferably a high concentration aqueous solution having the wetting agent 14 present in an amount of between about 20 and 100 percent, and most preferably about 25 percent, by weight of the solution.
  • the gravure roll 38 is preferably a metal roll of a type conventionally used in the printing art, and having a cell pattern known in the art as a "quad" pattern with between about 300 and 700 cells per 25,4 mm (1 inch) and a cell size of between about 1.5 and 4.0 CBM (cubic billion microns, volume per 6,45 cm 2 or 1 square inch).
  • the most preferred gravure roll is one known it the art as a 550 (cells per 25,4 mm or 1 inch) quad, 1.7 CBM.
  • the gravure roll preferably rotates at a speed of between about 20 and 120 percent of the line speed, and most preferably about 60 percent of the line speed (line speed is described below as preferably being between about 91,5 and 457,5 m/min (300 and 1,500 feet per minute).
  • line speed is described below as preferably being between about 91,5 and 457,5 m/min (300 and 1,500 feet per minute).
  • Fig. 4 A graph showing the percent surface concentration of the wetting agent as a function of gravure roll speed for a representative sample is shown in Fig. 4.
  • the transfer roll 24 is preferably a rubber roll of a type conventionally used in the printing art, and having a durometer hardness of between about 60 and 85.
  • the gravure roll 38 is spaced apart from the transfer roll 24 such that in operation a desired amount of the coating solution transfers to the transfer roll for subsequent application to the nonwoven material.
  • the distance between the transfer roll 24 and the gravure roll 38 which defines the nip 39 is preferably between about 1,5 and 12,7 mm (1/16 and 1/2 inch) to achieve the desired surface concentration, and is optimally about 4,77 mm (3/16 inch) when applying the coating solution to nonwoven materials having a basis weight of about 23,7 g/m 2 (0.7 osy).
  • the transfer roll 24 preferably rotates at a rate which advances the material at a line speed of between about 91,5 and 457,5 m/min (300 and 1,500 feet per minute), with an optimum line speed of about 152,5 m/min (500 feet per minute).
  • the backing roll 20 is preferably either a metal or rubber roll of a type well known in the printing art, having a durometer hardness of about 90. The backing roll 20 rotates at a rate which provides the same line speed as the transfer roll 24.
  • the spacing between the backing roll 20 and the transfer roll 24 which defines the nip 30 is preferably between about 6,3 and 19,1 mm (1/4 and 3/4 inch) and is optimally about 9,5 mm (3/8 inch) when coating nonwoven materials having a basis weight of about 23,7 g/m 2 (0.7 osy).
  • the resulting coated material 34 has a more uniform coating of wetting agent and has improved tensile strength over conventionally prepared coated materials.
  • a representative sample was produced by applying a 25 percent by weight "Triton X-102" aqueous solution to a 23,7 g/m 2 (0.7 osy) nonwoven, hydrophobic material. The solution was applied using an "inverted L” differential offset printer producing a line speed of 152,5 m/min (500 fpm) and a gravure roll speed of 91,5 m/min (300 fpm) (60% line speed).
  • the wet pick-up for the representative sample was determined to be about 0.9 percent and the average surface concentration of the wetting agent was about 0.3 percent solids (coat weight). No drying was necessary. This yielded a uniform distribution of about 0.24 grams of coating solution per 0,8 m 2 (1 square yard).
  • Figs. 2 and 3 With reference to Figs. 2 and 3, one can see graphically the uniformity of the surface concentration of the wetting agent on the representative sample in the cross-direction (Fig. 2) and in the machine-direction (Fig. 3).
  • the representative sample exhibited overall a 5.0 percent coefficient of variation in surface concentration across the material, and materials of the invention will generally exhibit a coefficient of variation in surface concentration of 10.0 percent or less.
  • Loss in tensile strength for the representative sample was determined (in accordance with RTM-6200) by comparing the tensile strength of treated material with untreated material for the same cross-direction or deckle position. Material treated in accordance with the present invention experienced a 5 percent loss in tensile strength. This compares with a typical tensile strength loss of at least 21 percent for coated materials prepared utilizing spray treatment and treatments requiring secondary drying over steam cans.
  • the printing process of the present invention coats the material from the transfer roll; therefore, only one side of the coated material is hydrophilic, while the other side is hydrophobic.
  • Hydrophilic material is wettable material that produces less than 20 mililiters of runoff; hydrophobic material produces greater than 20 mililiters of runoff.
  • a material having a hydrophilic and hydrophobic surface rapidly allows fluid to pass through and does not allow it to flow back.
  • such material acts as a "one way valve.” It has been observed that materials having basis weights between 16,9 g/m 2 and 33,9 g/m 2 (0.5 and 1.0 osy) which are treated in accordance with the present invention behave as one way valves when, after treatment, they are not wound up into roll form in a manner that causes contact between opposing sides of the material. It has also been observed that when materials having a basis weight of less than about 28,8 g/m 2 (0.85 osy) are rolled up after application of the wetting agent, some of the wetting agent transfers to the untreated side, producing a two-sided hydrophilic material. The time required for the wetting agent to transfer to the untreated side being dependent upon the basis weight.
  • Micropore filtration testing of materials treated in accordance with the invention showed reduced levels of Class I, Class II and Class III bacteria when compared with untreated materials.
  • Class I included Bacillus sp, Corynebacterium, other gram positive rods, mold and yeast (other than Candida albicans).
  • Class II included Staphylococcus sp. (other than S. Aureus), Pseudomonas sp. (other than P. Aeruginosa), Enterobacteriaceae (other than E. Coli and Salmonella sp.), other gram positive cocci, Oxidative-Fermentative bacteria, and other gram negative rods.
  • Class III included Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella sp., and Candida albicans. While the control had a total CFU of 17, none of the treated samples exceeded 10 CFU.
