There are many manufacturing procedures that make it easier to put on and take off gloves with additional surface treatment.
The fundamental difference in a glove’s finish is whether the inside is powdered or not. Powdered gloves, which are coated on the inside with food-grade cornstarch for easy changes when hands are wet, are preferred by some people. They are popular in applications where there is a lot of moisture. Glove molds were traditionally powdered to make removing the gloves from the mold easier. As a result, powder was already on the glove, and those that were made powder-free required an additional process to remove the residue. The Food and Drug Administration (FDA) banned powdered latex exam gloves from sale in the United States in January 2017 due to concerns that the cornstarch could impede wound healing and serve as a vehicle for the transmission of latex allergy. During the production process, powder-free gloves are given three different finishes :
Inside coating
Gloves with a polymer coating on the inside (silicones, acrylics, and hydrogels) have a smoother finish and less surface friction, making them easier to put on and take off. They are commonly applied to nitrile gloves as they are the premium gloves. It is important to be aware that skin irritation can be an important problem for healthcare professionals. It is no secret that the constant cycle of washing and gelling can leave healthcare professional’s hands feeling dry and uncomfortable. Irritated hands make it difficult to comfortably care for patients and some inside coating can nourish the hands of the glove wearer or at least limit the hand’s skin irritation.
Chlorination
Gloves are chlorinated by being washed in a solution or with chlorine gas, giving them a softer texture and a more comfortable feel as well as making them easier to put on and take off. After that, they are completely rinsed. Chlorination lowers the amount of remaining latex proteins in latex gloves to prevent allergic reaction. Because latex is tackier by nature, double chlorination is utilized in some gloves, notably thicker latex gloves, to make donning and doffing easier.
Polyurethane
Polyurethane is frequently applied on the inside of vinyl gloves to reduce surface tackiness and make the glove simpler to put on and remove.
