Are there any limitations and challenges in printing water-based ink on non-woven fabrics
Date: Jul 28 2023 From: Star Color
Water-based ink printing on non-woven fabrics can come with certain limitations and challenges. Here are some of them:
1.Absorption and spreading: Non-woven fabrics tend to have a relatively high absorption rate, which can cause water-based inks to spread and blur, leading to reduced print sharpness and clarity. This can be particularly challenging when trying to achieve fine details or precise designs.
2.Color vibrancy: Water-based inks may not produce colors as vibrant or intense on non-woven fabrics compared to other types of inks. The absorption properties of the fabric can cause the colors to appear dull or muted, resulting in reduced color accuracy and vibrancy.
3.Drying time: Water-based inks generally require longer drying times compared to solvent-based or UV-curable inks. The porous nature of non-woven fabrics can further slow down the drying process, prolonging production time and potentially causing issues such as smudging or transfer of wet ink.
4.Limited compatibility: Water-based inks may not be compatible with certain types of non-woven fabrics. Some non-woven fabrics have hydrophobic or water-repellent properties, which can prevent proper ink adhesion and penetration. In such cases, alternative printing methods or specialized pre-treatments may be required.
5.Durability and wash resistance: Water-based inks may exhibit lower durability and wash resistance on non-woven fabrics compared to solvent-based or UV-curable inks. The water-soluble nature of these inks can lead to color fading or bleeding when exposed to water or subjected to frequent washing, limiting their suitability for applications requiring long-lasting prints.
To overcome these limitations, various techniques and technologies have been developed, such as pre-coating non-woven fabrics to enhance ink adhesion, using pigmented or hybrid inks for improved color vibrancy and durability, and optimizing drying methods to minimize drying times. It's advisable to consult with printing experts or conduct specific tests to determine the most suitable printing approach for your particular non-woven fabric and desired outcomes.
