Glove Manufacturing Process

The final step of glove manufacturing involves stripping of the finished gloves from the molds using pneumatic air jets. The now bare molds are then given a thorough chemical wash and rinsing before entering the next dipping cycle. Typically a mold will be dipped 4-5 times in an hour and once a week they will be given a thorough scrub to remove built-up stains and residues. Periodically the molds are visually examined for defects and replaced.

Stripped gloves are hot-air tumbled to even them out as well as remove detachable powder. They are batched in bins, tagged and sampled for inspection. Operators examine the samples for visual defects, measure their weights and dimensions and check them for air leaks.

Batches that pass the inspections are routed for direct packing. Those that fail are bagged for rework and retest.

Passed gloves are also tested for physical properties. These are tensile strength and elongation at break before and after ageing to ensure they can withstand prolong storage and handling stress. All packed gloves are water tested for compliance to the maximum allowable leak failures called AQL. Batches that fail will be reworked or downgraded. Only gloves that meet the in-house specifications will be allowed to be shipped to customers warehouses.

Secondary Processes

Traditionally, powder was used to facilitate the release of gloves from formers during gloves forming in the manufacturing process and also to aid the donning of the gloves. However, it was found that powdered gloves posed a potential health risk to users who are sensitive to latex protein by way of powder being carrier of latex protein or contamination of surgical wounds. As a result, powder-free technology has been developed involving either chlorination or polymer coating, or a combination of both.

Chlorination

Chlorination has been one of the most popular methods of manufacturing gloves that don easily for the user without the addition of powder. It is a process whereby the rubber surface is exposed to chlorine solution with low concentration and rinsed with ammonia, water and other chemicals in order to reduce surface tackiness and remove most of the powder deposited on the glove surfaces.

As gloves are made from natural rubber or synthetic materials with a relatively high degree of surface friction that make them difficult to don, the chlorination process improves donability by decreasing the surface friction of the gloves.

Polymer Coating

Polymer coating on the glove surfaces eases the donning and removal of gloves. Polymer coatings are applied either to the outer surface of the glove or to both outer and inner surfaces.

Acrylic polymer is the main ingredient in the polymer coating process to coat the inner and outer surface of the gloves. These acrylic coatings are based on acrylate polymers that have elastic properties.
