Nitrile-coated gloves are the most common type of work gloves. Nitrile coatings are typically categorized into foam coatings and flat coatings. The sandy finish process is a treatment method applied to the coatings. It gives the surface a sandy or rough texture, which enhances the coatings’ Grip Performance. This article will take just three minutes to walk you through the manufacturing process of the sanding technique!
Features of Sandy Nitrile-Coated Gloves
Textured nitrile-coated gloves offer outstanding performance. They are commonly used in high-wear-and-tear work environments, such as the construction industry. The textured coatings offer the following features:
- Waterproof.
- Superior Grip Performance, suitable for dry, damp, and greasy environments. It also effectively blocks oil and grease, preventing them from penetrating the glove.
- Good abrasion resistance, making them more durable than standard nitrile rubber.
Sandy Finish Process for Nitrile-Coated Glove
The sandy finish process is primarily used to treat the surface of the coatings. Therefore, it is typically performed after the gloves have been dipped in the coating solution. The sandy finish process is as follows:
First Dip:
After the glove liner is knitted, it is placed over a former. The former, with the glove attached, is then immersed in the nitrile coating solution. The primary purpose of the first dip is to provide the glove with basic protective capabilities.
Immersion in Micro-Foam Nitrile:
This step creates a micro-porous foam structure on the glove surface. This improves breathability and facilitates the subsequent surface texturing process.
Texturing Process:
There are currently two common technical approaches for texturing: salt granule washing and texture transfer.
Salt Granule Washing:While the micro-porous foam is forming on the glove surface, but has not yet set, the glove is immersed in a salt solution. The salt reacts with the micro-bubbles, creating a texture with a more pronounced granular feel. The gloves are then rinsed with water to thoroughly remove any salt residue from the surface.
Texture transfer:Texture transfer involves placing the glove, after the liner has been knitted, over a specific former. The surface of this former is designed with a granular, sandblasted texture. The glove is then immersed in a solution. After immersion, it is turned inside out and washed.
Drying, Vulcanization, and Curing:
After washing, the gloves undergo a heating, drying, and curing process to stabilize and set the coatings.
