These additives are used in nonwovens, composites, and performance fabrics to improve adhesion between fibers or threads. Traditionally, bonding agents included synthetic resins or adhesives that complicated end-of-life processing. Modern solutions are shifting toward thermoplastic polymers with improved recyclability, bio-based adhesives, and reactive systems that reduce energy consumption during application. These innovations support sustainable design principles and reduce emissions in production. Digital sourcing platforms make it easier to identify bonding systems that align with circularity goals and regulatory frameworks, ensuring both performance and environmental responsibility.
