What Is the Double-Dipping Process for Nitrile Coated Gloves?
Double-dipping is a unique manufacturing process used for coated work gloves.
Compared to standard work gloves or single-layer coated work gloves. The double-dipping process produces double-coated gloves. They offer better flexibility and comfort, as well as superior stretchability. At the same time, the durability and protective performance of double-coated gloves are further enhanced.
This article will take just 3 minutes to give you a detailed introduction to the double-dipping manufacturing process!
What Is the Manufacturing Process of Double-Dipped Nitrile-Coated Work Gloves?
The main steps of the double-dipping process are as follows:
- Place the fabric liners over the molds.
- Dip into the coagulant solution. This step treats the surface of the gloves to improve the curing efficiency of the gloves and the coatings.
- Immerse in a polymer compound.
Typically: A suspension of synthetic rubber, plastic polymers, or natural latex. The first dip is primarily used to reinforce the structural integrity of the coated work gloves.
Note: Strict control of the viscosity of the dipping solution and the dipping time is essential. These factors affect the thickness and properties of the coated work gloves. - Second immersion of the gloves. The second coating layer is primarily intended to enhance protective properties. Such as chemical resistance, cut resistance, or grip performance.
- Vulcanization: Place the gloves in curing ovens for processing. This step improves the gloves’ chemical resistance and elasticity.
- Rinsing and pre-drying: Rinse the gloves to remove residual chemicals, then allow them to air dry.
Common latex dipping processes
Steps 2 and 3 above utilize the coagulant dipping process. Other common technical approaches in the industry for improving coating coagulation efficiency include heat-sensitive dipping and Straight dipping.
- Heat-sensitive dipping: The gloves are first heated to 135–170°F before being dipped.
- Straight dipping: By adjusting the viscosity of the suspension, the gloves are dipped directly without first being dipped in a coagulant.
Advantages of the Double-Dipping Process
The double-dipping process offers many benefits; the most common advantages are as follows:
- Smoother surface on coated work gloves:
Bubbles often appear on the glove surface during the first dip, which is difficult to completely avoid. A second dip results in a smoother surface and improves the glove’s appearance. - Superior durability:
The double-dipping process allows for thicker coatings and better film integrity. As a result, double-coated gloves offer superior durability and abrasion resistance. - Enhanced protection:
Single-dipped coatings have limited protection types. Double-dipping allows for the use of different dipping solutions. Therefore, double-coated gloves provide more comprehensive protection.
