Ionic Surfactant Adsorption on Cationized Lyocell Fibers

The most important phase in textile finishing processes is adsorption of chemical compounds and substances on textile materials surface. Lyocell fibers, like most textile fibers, are negatively charged in neutral and alkali aqueous solutions. Therefore, the adsorption of anionic textile auxiliaries, dyestuffs, optical brighteners and finishing agents is difficult due to repulsive forces. Therefore, in this paper Lyocell fibers were cationized with three different compounds - short chain quaternary ammonium compounds, 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride (CHPTAC), and long chain commercial products for the same purpose – cationic reactive polyammonium compounds Rewin OS (CHT/Bezema), and Rewin DWR (CHT/Bezema). Surfactants are essential for wet treatment of textiles. Its adsorption highly depends on ionogenity, particle size, and length of hydrophobic part as well as treatment conditions applied. For that reason, the ionic surfactant adsorption below and above critical micellar concentration (CMC) were investigated, as well as electrokinetic potential and specific amount of surface charge of such cationized Lyocell fibers.
