Reducing the interfacial tension between the two media (the antimicrobial agent with the nonionic) will permit the formula to penetrate the textile and surface more quickly while providing greater coverage on the surface. In Higgins-Shlisky this phenomenon was illustrated in Fig. 2A and Fig. 2B.

Abstract

L'invention concerne des compositions de traitement de textiles qui confèrent trois fonctions aux textiles auxquels elles sont appliquées : assainissement (détruire les microbes dans ou sur ceux-ci), conditionnement ou assouplissement, et exercice d'un effet antimicrobien résiduaire pour empêcher une réinfection immédiate après le traitement. Ces traitements de textiles trifonctionnels, ou trois-en-un, utilisant des composés d'organosilane, des tensioactifs non ioniques et cationiques, et des conditionneurs de textiles cationiques, et leur utilisation à titre d'agents microbicides et microbiostatiques, et de conditionneurs et assouplissants de textiles sont en outre décrits.
