Abstract
Surfactants as organic compounds are widely used in the processes of textile finishing and care with regard to different variations and specific hydrophilic/hydrophobic character. Specific behaviour of these compounds is partly based on the adsorption process. In this study the adsorption and desorption of ionic surfactants have been studied upon the influence of fibre composition and surfactant ionogenity as well as variation of hydrophobic chain length and hydrophilic group in the molecule. Textile fibres were characterized through electrokinetic potential, sorption characteristics and swelling capacity expressed by moisture regain and water retention value (WRV). Different types of cationic and anionic surfactants were adsorbed on cotton, wool, polyester and polypropylene fibres at 20°C during 60 minutes. The quantity of adsorbed surfactants on textile fibres was determined by potentiometric titration. The textile fibres were centrifuged afterwards and the amount of surfactants was determined in the centrifugate, respectively. Drying followed at 60°C. The desorption of surfactants was performed at 20°C during 30 minutes. The results showed a correlation between amount of adsorbed, desorbed and residual surfactants and swelling capacity expressed through WRV.
Kurzfassung
Ionische Tenside werden als organische Verbindungen in der Textilveredlung und -pflege hinsichtlich ihrer verschiedener Varianten und ihres spezifischen hydrophilen/hydrophoben Charakters weitverbreitet verwendet. Das spezifische Verhalten dieser Verbindungen beruht teilweise auf dem Adsorptionsprozess. In dieser Studie wurden Adsorption und Desorption der ionischen Tenside auf den Einfluss der Faserzusammensetzung und die Ionogenität von Tensiden sowie die Veränderung der hydrophoben Kettenlänge und der hydrophilen Gruppe im Molekül geprüft. Die Textilfasern wurden durch elektrokinetisches Potenzial, Sorptionseigenschaften und Quellfähigkeit ausgedrückt durch Feuchtigkeitszuschlag und Wasserrückhaltewert (WRW) gekennzeichnet. Verschiedene kationische und anionische Tenside wurden bei 20°C auf den Baumwoll-, Wolle-, Polyester- und Polypropylenfasern 60 Minuten lang adsorbiert. Die Quantität der auf den Textilfasern adsorbierten Tenside wurde durch potenziometrische Titration bestimmt. Die Textilfasern wurden danach zentrifugiert, und die Menge der Tenside wurde in dem Zentrifugat bestimmt. Das Trocknen erfolgte bei 60°C. Die Desorption von den Tensiden wurde bei 20°C während 30 Minuten durchgeführt. Anhand der Ergebnisse konnte eine Korrelation zwischen der Menge von adsorbierten, desorbierten und restlichen Tensiden und der durch WRW ausgedrückten Quellfähigkeit ermittelt werden.
