PU-coated gloves offer excellent elasticity and dexterity. They are suitable for applications such as parts assembly and other precision machining operations. In the past, PU-coated work gloves were primarily manufactured using DMF (dimethylformamide). However, DMF is toxic. This creates risks during production, and if the coating is not properly cleaned, it may also pose safety risks to the wearer. This article will explain the PU glove coating process in just 3 minutes.
What is the PU coating process?
The amount of DMF used in traditional formulations is now strictly regulated. The M-tide R&D team uses safer polyurethane solvents in production. The main solvent components include DMSO, NMP, and other safer reagents. This formulation effectively reduces the viscosity of the coating solution. This helps ensure the quality of the coated gloves.
PU coating process flow:
- Place the knitted gloves onto the molds
At the same time, remove dust and adjust the knuckle area. Ensure the gloves are flat and free of wrinkles. - Dip the gloves into a safer polyurethane solution
The dipping time is usually 15–55 seconds. (Adjusted according to the required protection level.) - Water Bath Treatment
After dipping, the gloves undergo water-bath treatment in a series of baths at different temperatures. This stabilizes the PU coating to form a film, while the solvent dissolves into the water. This effectively removes residual reagents from the glove surface. - Drying Process
The gloves are then placed in a high-temperature tunnel oven. They are dried at 100–110°C for about 60 minutes. This process effectively enhances the protective performance of the coating. - High-Vacuum Solvent Recovery Technology
During the water-bath stage, part of the solvent dissolves in the water.
Using vacuum decompression and distillation technology, the solvent is separated and recovered. Solvent components in the water can be effectively recovered.
What are the characteristics of PU-coated gloves?
PU-coated gloves have a unique structure. The coating is lightweight, thin, and closely bonded to the glove liner. Key features include:
- Excellent abrasion resistance
- High tensile strength
- Resistance to oil and certain chemicals
- Excellent oxidation resistance and some protection against ozone.
- Moderate breathability
PU-coated gloves are commonly used in light precision assembly industries.
WPU Finishing Process
To make the gloves easier to put on and take off, M-tide applies WPU (waterborne polyurethane), mainly to the inner layer of the gloves. It provides a degree of cut resistance and elasticity. It also improves ease of donning and removal.
WPU is non-toxic and non-polluting. It is environmentally friendly. It improves the wearing comfort of work gloves.
