摘要:
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 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.
摘要:
A textured elastomeric article and a method of making such an article is disclosed. The article includes a substrate body having an inside surface and a plurality of alkaline earth salt particles embedded within at least a portion of the inside surface but not extending through the thickness of the article such that no separate binder material is needed to affix the particles.
摘要:
Disclosed herein is an elastomeric article having a hydrogel donning coating. The hydrogel donning coating is made of a copolymer of hydroxy ethyl acrylate (HEA), hydroxy ethyl methacrylate (HEMA), and acrylic acid. The hydrogel donning coating is applied to the elastomeric article using an aqueous hydrogel dipping solution containing the hydrogel donning coating copolymer. The aqueous hydrogel dipping solution demonstrates thixotropic characteristics which allows for better manufacturing process control.
摘要:
An elastomeric article encompassing an enclosure with an interior surface having at least two regions or zones is described. The first region has a higher coefficient of friction than the second region, in which an average coefficient of friction (COF) ratio between the first and second regions of the wearer-contact surface ranges from about 1:1.2 to about 1:3.8 or 4.0. The first region has either the same or smaller surface area than the second region, and is situated at or near an opening to the enclosure. The second region is coated with a hydrogel-based donning layer. A process of making the elastomeric article is also provided. Examples of elastomeric articles according to the invention include surgeons' gloves that exhibit good lubricity and donning characteristics, and have an improved cuff-slippage control.
