From a theoretical standpoint, the driving force for the deposition of ditallowdimethylammonium chloride ("DTDMAC" or "quat') onto cotton must be distinguished from the nature of its interaction with cellulose. We found that the driving force is purely hydrophobic. Due to its strong hydrophobicity, DTDMAC is expelled out of the aqueous rinse bath and deposits onto available surfaces. Besides its tendency not to leave the cotton surface and return to solution (hydrophobic effect), it binds to cellulose by weak London dispersion forces. A strong Coulombic interaction occurs only when a negative charge is present. Consequently, the strong affinity of DTDMAC for cellulose mainly results from the large specific surface area of the fiber; negative charges play a secondary role. Much experimental evidence supports the hydrophobic nature of DTD-MAC adsorption onto cellulose. DTDMAC deposits onto charge-free surfaces; its deposition is mainly governed by the available surface area, not by the surface nature. The hydrophobic nature of the interaction of DTDMAC with cotton may be displayed and distinguished from electrostatic binding. Structural effects demonstrate the correlation between hydrophobicity, deposition and the softening power of quaternaries. This model proposes a single mechanism to account for the deposition of DTDMAC onto cotton and synthetics. It is consistent with experimental facts that remain unexplained by the electrostatic model. 72, 137-143 (1995). JAOCS
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
