Precautions for water-based ink in non-woven fabric printing
Date: Aug 15 2023 From: Star Color
Water-based ink is commonly used in non-woven fabric printing due to its eco-friendliness, low toxicity, and ease of cleanup. However, there are some precautions you should take to ensure a successful and safe printing process. Here are some key precautions for using water-based ink in non-woven fabric printing:
1.Fabric Preparation: Ensure that the non-woven fabric is clean and free from any dirt, dust, or contaminants that may interfere with ink adhesion. Pre-treat the fabric if necessary to enhance ink absorption and color vibrancy.
2.Testing: Always perform a compatibility and adhesion test before full-scale printing. This will help you determine if the ink adheres well to the non-woven fabric and if the desired color and finish are achieved.
3.Ink Selection: Choose high-quality water-based inks specifically designed for non-woven fabric printing. Different inks have different properties, so make sure the ink you select meets your printing requirements.
4.Proper Mixing: If you need to mix ink colors, follow the manufacturer's guidelines for accurate color reproduction. Improper mixing can result in inconsistent colors or poor printing quality.
5.Screen Cleaning: Keep the screens and printing equipment clean to prevent any cross-contamination between different ink colors. Regularly clean the screens to avoid clogging and ensure smooth printing.
6.Humidity Control: Maintain appropriate humidity levels in the printing environment. Excessive humidity can lead to drying issues and affect the ink's performance, while low humidity can cause the ink to dry too quickly on the screens.
7.Drying and Curing: Allow sufficient drying and curing time for the printed fabric. Follow the recommended curing temperature and time provided by the ink manufacturer to achieve maximum adhesion and durability.
8.Safety Precautions: Wear appropriate personal protective equipment (PPE) such as gloves and safety glasses when handling water-based inks. While these inks are generally less toxic than solvent-based inks, it's essential to take precautions to avoid skin or eye contact.
9.Waste Disposal: Dispose of ink waste and cleaning solvents according to local regulations and best practices for environmental safety.
10.Storage: Store water-based inks properly in a cool and dry place, away from direct sunlight, to maintain their quality and consistency.
By following these precautions, you can ensure a successful water-based ink printing process on non-woven fabrics while maintaining safety and environmental standards. Always refer to the ink manufacturer's guidelines and recommendations for the best results.
