Glove Manufacturing Process

The next stage involves drying and curing the wet gloves inside a long and deep oven heated either electrically, by natural gas or hot air. Curing, or vulcanization, converts the gloves into an elastic state by causing the chemicals added during compounding to react with the rubber molecules in the latex. This is the most critical step as without curing the gloves will not be elastic as well as they will tear easily.

Vulcanization is a chemical process, discovered by Charles Goodyear, by which the physical properties of natural or synthetic rubber are improved. It consists principally of heating rubber with sulfur and other substances, such as accelerators and activators. The sulfur does not simply dissolve or disperse in the rubber, but rather combines chemically, mostly in the form of cross-links (bridges) between rubber chain molecules and the sulfur atoms. On the other hand, accelerators and activators act as catalysts to initiate the process as well as boost the reaction at room temperatures.

Cross-linking is analogous to net building using strings that are knotted together. The sulphur atoms reside in the nodes that link the rubber molecule chains. Just as a net provides strength and a network to catch fishes, cross-linked rubber in latex provides the base upon which gloves are moulded.

Vulcanized rubber has higher tensile strength and resistance to swelling and abrasion, and is elastic over a greater range of temperatures. In other words, natural rubber without undergoing vulcanization will eventually become too brittle in cold weather or become sticky in hot weather.

Upon exiting the oven the gloves are dipped once again into hot water to perform a dry film post-leaching wash to extract residual proteins and chemicals that bloomed to the glove surface. It has been established that a combination of wet and dry leaching has been very effective in removing residual proteins and chemicals and has significantly reduced the number of cases of protein allergies and sensitization.

The leached gloves are then dipped into a slurry of corn starch and dried. This layer of corn starch assist in glove removal and donning.
