Poor adhesion is one of the most common problems in silicone heat transfer printing on gloves.
Manufacturers often experience issues such as:
Silicone transfer peeling off
Edges lifting after heat press
Poor bonding after washing
Transfer falling off during stretching
Incomplete adhesion on glove surfaces
Unlike direct printing, silicone heat transfer involves multiple layers and processes, including PET release film, silicone layers, hot melt adhesive, heat pressing, and fabric bonding.
If any part of the process is not properly controlled, adhesion problems can occur.
This article explains the main causes of poor adhesion in glove silicone heat transfer printing and how to improve bonding performance.
How Silicone Heat Transfer Works on Gloves
The standard transfer printing process is:
PET Film
↓
Silicone Printing Layer
↓
Hot Melt Adhesive Layer
↓
Heat Press Transfer
↓
Bonding onto Glove Fabric
The final adhesion mainly depends on whether the hot melt adhesive can fully bond with the glove material during heat pressing.
Hot Melt Adhesive Does Not Match the Glove Fabric
This is one of the biggest causes of poor adhesion.
Different glove materials have different surface properties.
For example:
Nylon gloves
Polyester gloves
Waterproof gloves
PU-coated gloves
Spandex gloves
Some fabrics have low surface energy, making it difficult for the adhesive to penetrate into the fibers.
As a result:
Transfer peels easily
Edges lift
Washing resistance becomes poor
Solution
Choose hot melt adhesive according to the glove fabric type.
High-stretch gloves usually require elastic adhesive systems, while waterproof or coated gloves may require stronger bonding formulations.
Heat Press Temperature Is Too Low
Hot melt adhesive requires enough heat to melt and bond with the glove surface.
If the temperature is too low:
Adhesive cannot fully activate
Silicone transfer only sticks partially
Corners may peel after pressing
This problem is very common during fast production.
Common Symptoms
Partial transfer
Weak bonding
Easy peeling by hand
Solution
Optimize the heat press temperature according to:
Adhesive type
Silicone thickness
Glove fabric
Transfer structure
Heat Press Pressure Is Insufficient
Gloves are not completely flat.
Finger areas and textured surfaces often reduce transfer pressure.
Without enough pressure:
Adhesive cannot fully contact the fabric
Air gaps remain inside the transfer layer
Edges fail to bond properly
Solution
Increase pressing pressure
Use proper silicone pads
Improve pressure uniformity
Use glove-specific heat press molds if necessary
Heat Press Time Is Too Short
Even with correct temperature and pressure, short pressing time can still cause poor adhesion.
The adhesive needs enough time to:
Melt
Flow
Penetrate fabric fibers
Form stable bonding
If pressing time is insufficient:
Transfer may initially stick
But peel after washing or stretching
Solution
Adjust pressing time according to:
Transfer thickness
Fabric density
Adhesive flow characteristics
Silicone Layer and Hot Melt Adhesive Have Poor Compatibility
Not all silicone systems are designed for transfer printing.
Some silicone materials have poor bonding compatibility with hot melt adhesive layers.
This may cause:
Layer separation
Delamination
Peeling during stretching
Solution
Use transfer silicone specifically developed for:
Heat transfer printing
Hot melt adhesive bonding
High-elastic glove applications
Incorrect Screen Printing Parameters
Screen printing directly affects adhesive thickness and bonding performance.
Problems may occur if:
Mesh count is incorrect
Silicone layer is too thin
Adhesive layer is uneven
Printing pressure is unstable
These issues reduce transfer stability and adhesion strength.
Solution
Optimize:
Screen mesh count
Squeegee hardness
Printing pressure
Printing speed
Adhesive coating thickness
Glove Surface Treatment Affects Adhesion
Some gloves contain:
Waterproof coatings
Oil-resistant treatments
PU coatings
Anti-slip surface treatments
These coatings reduce adhesive penetration ability.
As a result, the transfer may appear bonded at first but peel later during use.
Solution
Test adhesion before production and select adhesive systems suitable for coated fabrics.
Conclusion
Poor adhesion in glove silicone heat transfer printing is usually caused by multiple factors together, including:
Hot melt adhesive selection
Heat press temperature
Pressure
Pressing time
Silicone compatibility
Screen printing process
Glove fabric surface
By optimizing both materials and printing conditions, manufacturers can significantly improve transfer adhesion, washing resistance, and long-term durability on gloves.
