The presented study focuses on the development of a pad-dry-thermofix functional coating process using a mixture of microporous aluminosilicate particles in diverse bath formulations to impart UV-rays’ blocking, thermal stability and easy-care properties to the cotton fabric. The surface characterization’ results of zeolite-coated/cross-linked textiles provided evidence of acceptable UV-rays’ blocking properties and increased thermal stability, as well as enhanced tensile strength and breaking tenacity without decreasing the whiteness degree considerably. Moreover, the dry crease recovery angle increased for the cotton fabric cross-linked via an mDMDHEU, and decreased significantly using 30 g/L zeolites influencing negatively on qualitative values. TG/DTA results have proven the enlarged thermal stability of aluminosilicate coated cotton, although the combustion was not prevented.

The aim of this research was to apply three different types of zeolites and the combination thereof in the form of a very fi ne powder, together with different chemicals and additives on polyamide knitted fabric according to an industrially acceptable exhaustion procedure in order to study changes in the morphology, optical properties and wettability of surfaces. The obtained results show the suitability of the employed exhaustion procedure, depending on the type of zeolite and the composition of the treatment bath. The results also provided evidence of the enhanced wettability of PA fabrics using 4A and 13X zeolites in combination with selected additives.

The aim of this research was to apply the mixture of different zeolites in the form of a very fine powder on cotton fabric. Zeolites were analysed using SEM, FTIR and gas physiosorption. The obtained results revealed the presence of three different types of zeolites within the mixture, which were efficiently applied onto cotton fabric according to pad-dry-cure procedure in combination with easy-care finishing imparting fabrics’ good to very good UV-blocking properties without adversely affect the fabrics’ mechanical characteristic.

The purpose of this study was to evaluate the impact of different industrially-viable procedures on the deposition of selected zeolite particles on the surface of cellulose textiles. Thus, zeolites were applied onto cotton fabrics according to exhaustion and coat-dry-thermofix. Herein, the impact of numerous operational parameters during the individual application procedure (concentration of zeolites, addition of crosslinking agents and/or auxiliaries, temperature, treatment time, etc.) on the surface morphology of zeolite-modified cellulose textiles was studied by means of SEM and FTIR techniques.

The aim of this research was to apply four different types of zeolites in the form of a very fine powder together with different chemicals and auxiliaries on polyamide knitted fabric according to exhaustion procedure in order to study the changes in fabrics’ morphology and optical properties. The results obtained by surface morphology observation and identification of specific molecular vibrations of zeolite coated polyamide knitted fabrics proven the suitability of employed exhaustion procedure regarding the type of zeolite used as well as composition of treatment bath. Consecutively, the fabrics’ optical properties were changed in both, UV and visible regions, i.e. zeolite-treated samples become lighter. Moreover, reflectance curves of those PA fabrics treated only by zeolites without auxiliaries decreased the most in the spectrum’ UV region, implying stronger absorption intensity and thus, higher UV-rays blocking properties in comparison to the reference.
