Salts of hydroxy acids include functional groups capable of forming "hybrid" ionic bonds with fibers or particles and another functional group capable of forming a hydrogen bond or "hybrid" ionic bond with the fibers when the binder forms a "hybrid" ionic bond with the particles or a hydrogen, coordinate covalent, or "hybrid" ionic bond with the particles when the binder forms a "hybrid" ionic bond with the fibers. Amino acids are also described as binders capable of forming "hybrid" ionic or ionic bonds between fibers and particles. Salts of bases, such as choline chloride are also described as being useful binders for attaching particles to fibers. The salts of bases form ionic bonds with either the particles or the fibers. Such binding systems provide viable alternatives to existing binding systems.

Des sels d'acides hydroxy comprennent des groupes fonctionnels pouvant former des liaisons ioniques "hybrides" avec des fibres ou particules, et un autre groupe fonctionnel capable de former une liaison hydrogène ou une liaison ionique "hybride" avec ces fibres quand le liant forme une liaison ionique "hybride" avec ces particules ou un hydrogène ou des liaisons covalentes coordonnées, ou une liaison ionique "hybride" avec ces particules, quand ce liant forme une liaison ionique "hybride" avec ces fibres. On décrit aussi des acides aminés en guise de liants capables de former des liaisons ioniques, éventuellement "hybrides", entre ces fibres et particules. On décrit aussi des sels de bases, tels que le chlorure de choline, qui sont des liants utiles pour fixer des particules à des fibres. Ces sels de bases forment des liaisons ioniques soit avec les particules soit avec les fibres. Ces systèmes de liaison constituent des solutions de rechange viables face aux systèmes de liaison existants.
