textile manufacturers and end users alike have been searching for ways to improve the surface properties of natural and synthetic fibers. specifically, there is a need to improve adhesion, wettability, printability, dyeability, as well as to reduce material shrinkage. methods of modifying fiber properties to make polypropylene dyeable, including the process of copolymerization with polymers which can be dyed, have been evaluated. traditional latex systems and primers with low melt points have been used to coat fabrics to promote ink adhesion, heatsealing and thermoforming performance.
