What are the recommended curing or drying methods for water-based ink on non-woven fabrics
Date: Jul 31 2023 From: Star Color
When it comes to curing or drying water-based ink on non-woven fabrics, there are several recommended methods you can consider. The choice of method depends on the specific equipment and resources available to you. Here are a few common techniques used in the industry:
1.Heat curing: This method involves using heat to evaporate the water content from the ink and accelerate the drying process. It can be achieved through various means, such as conveyor dryers, heat tunnels, or heat presses. The temperature and duration of heat exposure should be carefully controlled to avoid damaging the non-woven fabric.
2.Air drying: Allowing the water-based ink to air dry naturally is a straightforward and cost-effective method. However, it may take longer compared to other curing methods, and the drying time will depend on environmental factors such as humidity and temperature. Adequate ventilation is crucial to facilitate drying.
3.Infrared (IR) drying: Infrared drying utilizes IR lamps to emit heat energy that quickly evaporates the water content from the ink. This method can be efficient and allows for faster drying compared to air drying. Again, it's important to regulate the temperature and distance between the IR lamps and the non-woven fabric to prevent overheating.
4.Forced air drying: This technique involves using fans or blowers to circulate air and aid in the evaporation of water from the ink. It can be combined with other drying methods to accelerate the process. Controlling airflow and optimizing the drying environment can help achieve desired results.
5.UV curing: Although less common for water-based inks, UV curing is an effective method that utilizes ultraviolet light to polymerize and cure the ink. However, this method requires the use of specific UV-curable inks and UV light sources.
It's important to note that the choice of curing or drying method may also depend on the specific properties of the water-based ink you are using. Always refer to the manufacturer's recommendations and conduct small-scale tests to determine the most suitable method for your application.
