Permeability: Ink is usually a mixture of water and pigment, in which water is the main solvent. The molecular size of water molecules in ink is small and can penetrate into the fiber structure of industrial nonwovens. Once infiltrated into the fiber, the pigment in the ink will remain on the cloth to form words or patterns.
2. Adhesion: The pigment in the ink can be adsorbed on the fiber surface by physical or chemical means, so as to achieve adhesion with industrial non-woven fabrics. Some components in the ink may interact with the fiber surface, such as electrostatic adsorption and hydrogen bonding. , so that the ink is more firmly attached to the cloth to prevent easy fading or blurring.
