Screen printing binder is a key component in screen printing, acting as the medium that carries pigments and adheres them to the fabric. Think of it as the glue that holds your design onto the material.
In more detail, screen printing binder:
- Carries the Pigment: The binder is a clear or translucent liquid that suspends the pigments or dyes, allowing them to be transferred through the screen.
- Adheres to the Fabric: Once printed, the binder creates a film that bonds the pigment to the textile fibers, ensuring the design remains intact after washing and wear.
- Influences the Print's Characteristics: The type of binder used affects the print's softness, durability, and washability. Different binders are formulated for specific fabric types and desired finishes.
Types of Screen Printing Binders:
While there are various types, some common ones include:
- Water-Based Binders: These are environmentally friendly and produce a soft, breathable print. SFXC offers an extra-soft, water-based, and solvent-free screen printing binder that is suitable for bright colors on light fabrics and poly-cotton blends. It can be mixed with special effect pigments and inks (using a 6% pigment load).
- Plastisol Binders: Plastisol is a PVC-based ink that provides vibrant, durable prints. However, it requires higher temperatures for curing and isn't as eco-friendly as water-based options.
- Silicone Binders: Known for their excellent stretch and durability, silicone binders are often used for sportswear and performance apparel.
Choosing the Right Binder:
Selecting the appropriate binder depends on factors such as:
- Fabric Type: Different fabrics require different binders for optimal adhesion.
- Desired Finish: Consider whether you want a soft, matte, or glossy finish.
- Durability Requirements: For garments that will be washed frequently, choose a binder known for its washability.
- Environmental Considerations: Water-based binders are generally considered more environmentally friendly.
In summary, screen printing binder is the crucial element that enables you to transfer your design onto fabric and ensures its longevity. Its properties significantly impact the final print's look, feel, and durability.
