Printed nonwoven substrates for use in personal care articles
a non-woven substrate and personal care technology, applied in the field of printed non-woven fabrics and films, can solve the problems of difficult to produce printed images on such hydrophobic substrates, disadvantages of hydrophobicity, etc., and achieve the effects of improving color and/or brightness, increasing the adhesion of ink composition to the substrate, and improving the dot gain of ink composition

Benefits of technology
[0005] The present invention also provides a method of printing on a substrate, the method of printing includes the steps of: providing a substrate, heating an ink composition to a temperature Ti, depositing the ink composition on a portion of the substrate, heating a second composition to a temperature T that is greater than or equal to Ti, and depositing the second composition over the portion of the substrate that includes the ink composition. In certain embodiments, the step of depositing the second composition over the portion of the substrate that includes the ink composition causes the ink composition to melt. In certain embodiments, the step of depositing the second composition over the portion of the substrate that includes the ink composition enhances dot gain of ink composition. Desirably, depositing the second composition over the portion of the substrate that includes the ink composition increases adherence of the ink composition to the substrate. More desirably, depositing the second composition over the portion of the substrate provides a sacrificial layer that provide abrasion resistance. Still more desirably, depositing the second composition over a portion of a color image improves the color and / or brightness of the image.
Problems solved by technology
Polymers that are used to form theses, such as polyolefins, are naturally hydrophobic, and for many uses hydrophobicity is a disadvantage.
More particularly, it is difficult to produce printed images on such hydrophobic substrates.

[0057] Each of the following examples were prepared by first printing four stripes of four different ink colors on a spunbonded nonwoven fabric, such as the spunbonded nonwoven fabric used in the outercover laminates of HUGGIES Supreme diapers. Four separate stripes of color, one stripe of each of four colors, were printed on spunbonded nonwoven fabrics using four inks contained in a hotmelt printing test kit obtained from Spectra Incorporated of Lebanon, N.H. The inks obtained from Spectra Incorporated designated part numbers 7053-803, 7054-803, 7057-803, 7058-803 and 7061-028 were used to print four separate and distinct stripes on the spunbonded nonwoven fabric.
[0058] Two 8-inch wide stripes were printed via an inkjet printing apparatus obtained from Spectra, Inc. of Lebanon, N.H. The inkjet printhead of inkjet printing apparatus was heated to 125° C. The inks were jetted as an “all pattern” meaning all the 80 nozzles in the printhead were fired continuously to obtain 100 dot pe...

A personal care product, for example a diaper, that includes a surface upon which is disposed graphics, wherein the graphics comprise an ink composition applied to the substrate at a temperature and further comprises a layer that comprises a hotmelt composition that is applied over the graphics at a temperature that is greater than the temperature that the graphics were applied is provided.
Description
BACKGROUND OF THE INVENTION [0001] The present invention is directed to printed nonwoven fabrics, films, and laminates of nonwoven fabrics and / or films. [0002] Polymers are used extensively to make a variety of products which include blown and cast films, extruded sheets, injection molded articles, foams, blow molded articles, extruded pipe, monofilaments, fibers and nonwoven fabrics. Polymers that are used to form theses, such as polyolefins, are naturally hydrophobic, and for many uses hydrophobicity is a disadvantage. Polyolefins, such as polyethylene and polypropylene, are used to manufacture polymeric fabrics which are employed in the construction of such disposable absorbent articles as diapers, feminine care products, incontinence products, training pants, wipes, and so forth. Such polymeric fabrics often are nonwoven fabrics prepared by, for example, such processes as melt-blowing, carding, coforming and spunbonding. It would be desirable to provide a method of improving the...
