Abstract Exposure of reactive chemical functional groups through controlled surface lipid removal provides a means for covalent attachment of novel molecular entities to the wool fiber surface. Cleavage of the dominant lipid in the epicuticle, 18-methyleicosanoic acid (18-MEA), from the underlying proteinaceous layer was employed, prior to further surface modification, by means of aqueous hydroxylamine treatment. Treatments utilizing covalent bonding to the surface through thiol, carboxyl, amine, or other reactive chemical groups offer improved durability to textile processing, such as dyeing and laundering. This surface modification investigation compared and assessed the attachment and ...
