Abstract
A printed nonwoven web having improved oil crockfastness when an ink composition is applied to an outer surface of the nonwoven is generally disclosed. For example, an ink composition that has improved resistance to rub off of the web, even if the ink composition contacts an oily substance (e.g., baby oil, lotion, etc.), can be printed on a surface of the web. The nonwoven web can be a layer in a laminate having at least a film layer and the nonwoven web layer. For example, the printed laminate can be used as the outercover of an absorbent article.
Claims26
A nonwoven web defining a visible surface comprising:
- synthetic fibers interlaid to form the nonwoven web, and
- an ink composition applied to the visible surface of the nonwoven web, wherein the ink composition comprises a crosslinking agent in an amount of greater than about 3.5% by weight based on the dried weight of the ink composition, wherein the crosslinking agent comprises an aziridine oligomer with at least two aziridine functional groups.
An absorbent article comprising:
- a liquid permeable topsheet;
- an absorbent core;
- and
- a liquid impermeable backsheet, wherein the absorbent core is positioned between the topsheet and the backsheet, the backsheet comprising a nonwoven web overlying a film layer such that the film layer faces the absorbent core and the nonwoven web defines an outer visible surface of the absorbent article, wherein an ink composition is applied to the outer visible surface, wherein the ink composition comprises a crosslinking agent in an amount of greater than about 3.5% by weight based on the dried weight of the ink composition, wherein the crosslinking agent comprises an aziridine oligomer with at least two aziridine functional groups.
A method of printing to a nonwoven web, the method comprising:
- providing a nonwoven web of synthetic fibers, wherein the nonwoven web has a visible surface, and
- printing an ink composition to the visible surface of the nonwoven web, wherein the ink composition comprises a crosslinking agent in an amount of greater than about 2% by weight based on the wet weight of the ink composition, wherein the crosslinking agent comprises an aziridine oligomer with at least two aziridine functional groups.
