Influence of cationized cotton on the stability of cellulose-aluminosilicate composite

In this study cellulose materials were pre-treated with cationic agent in order to obtain more reactive supports for in situ synthesis of alumosilicate microprous compounds. Cation-generating polyammonium agent was applied by padding of cotton fabric with hydrogel. The synthesis of aluminosilicate microporous compound on the cellulose material as a matrix was carried out using a conventional oven. The stability and durability of the so obtained cellulose-aluminosilicate composite material was performed by a wash test. The properties and structure of these composites were characterized by FTIR spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and electrokinetic potential. The results indicated that probably a more stable bonding between cellulose and microporous aluminosilicate was achieved i.e. a feature of great importance for for the long lasting wash durability.
