Fundamental Aspects of Aminoalkyl Siloxane Softeners by Molecular Modeling and Experimental Methods

The global textile industry has an ongoing need for improved softening products. Current materials systems, including those with siloxane polymers, exhibit certain limi tations such as yellowing, high cost, and low softening efficiency. Investigations into fabric softening mechanisms invoke molecular modeling tools to simulate siloxane polymer and cotton fiber interactions at the molecular level. This research describes how certain polymer types exhibit fundamentally enhanced siloxane and fiber interactions within particular pH ranges. Molecular modeling results are also correlated with empirical findings. The output of this research adds insight into efforts to understand fabric softening phenomena.
