An elastomeric article (e.g., glove, condom, and so forth) coated with a hydrogel is provided. The hydrogel coating facilitates dry and/or damp donning. In addition, due to its low coefficient of friction, the hydrogel allows stripping of a dip-formed article without the use of an antiblocking powder. Thus, the present inventors have discovered that certain treatment steps, such as chlorination and./or lubrication, conventionally conducted "off- line" (i.e., after stripping) are no longer required. Moreover, even when such treatments are used, they may conducted "in-line" (i.e., before stripping). The ability to eliminate certain off-line treatment steps provides a significant improvement in the efficiency of the forming process.
L'invention concerne un article élastomère (par exemple, un gant, un préservatif, etc.) recouvert d'un hydrogel. Ledit revêtement d'hydrogel facilite l'enfilage à sec et/ou humide. Du fait de son faible coefficient de friction, l'hydrogel permet d'enlever un article formé par trempage sans utiliser de poudre antibloquante. Les inventeurs ont découvert que certaines étapes de traitement, telles que la chloration et/ou la lubrification, classiquement effectuées hors ligne (c'est-à-dire, après l'enlèvement) ne sont plus nécessaires. En outre, même lorsqu'on utilise ces traitements, ils peuvent s'effectuer en ligne (c'est-à-dire, avant l'enlèvement). Le fait de supprimer certaines étapes de traitement hors ligne apporte une amélioration significative dans le procédé de formation.
