What is it for?
Conveyor dryers are essential equipment in the direct-to-garment (DTG) printing process, designed to cure or dry ink directly onto textiles. They ensure the ink adheres properly to the fabric, achieving vibrant colors and durable prints.
-
Why is it important?
- Ensures proper curing of ink, preventing smudging or fading after printing.
- Increases production efficiency by rapidly drying garments, reducing turnaround times.
- Improves print quality by eliminating moisture and ensuring consistent ink absorption.
How does it work? Conveyor dryers use a combination of heat and airflow to cure DTG ink effectively. Garments printed with water-based or discharge inks pass through a heated chamber on a conveyor belt, where controlled temperature and airflow settings facilitate the curing process.
- The conveyor belt moves garments through the dryer at a consistent speed, ensuring even drying.
- Heating elements and fans regulate temperature and airflow, optimizing drying conditions for different types of ink and fabrics.
What are the benefits?
- Achieves vibrant, durable prints with excellent color saturation.
- Increases production capacity by drying multiple garments simultaneously.
- Reduces labor costs and manual handling compared to alternative drying methods.
What are the common issues and how can you fix them?
- Inadequate curing: Adjust temperature and belt speed to ensure sufficient drying time.
- Uneven drying: Ensure proper airflow distribution across the conveyor belt.
- Maintenance issues: Regularly clean heating elements and inspect conveyor components to prevent malfunctions.
What are some of the best practices and common mistakes?
-
Best Practices:
- Monitor and adjust temperature and conveyor speed based on ink type and fabric.
- Conduct regular maintenance to keep equipment in optimal condition.
- Train operators on proper loading techniques to maximize efficiency and quality.
-
Common Mistakes:
- Over-drying or under-drying garments due to incorrect temperature settings.
- Neglecting regular maintenance leading to equipment breakdowns and downtime.
- Failing to optimize airflow, resulting in uneven drying and inconsistent print quality.
