Essential in post-processing and storage, conditioning agents improve fiber manageability and prevent brittleness, especially in natural and regenerated fibers. Older formulations may contain oily residues or volatile components that are now being phased out. Recent developments focus on non-toxic emulsions and biodegradable lubricants that ensure fiber integrity without adding burdens to wastewater systems. Their improved efficiency also supports lower dosage levels and better compatibility with downstream treatments. B2B directories enable manufacturers to access conditioning solutions that meet both technical and environmental specifications, facilitating responsible sourcing at scale.
