<p>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.</p> |
