Sensors that enable online detection of ecological parameters in dyeing processes and washing waters of laundries were developed and tested. With the aid of the online sensor control of the laundering procedure in the laundry it was found that up to 30 % of water savings could be realized. The combination of developed sensors (pH, conductivity, temperature, color, redox potential, active oxygen content) was considered. The most reasonable online sensor device for laundries was a relevant UV-light sensor for the identification of surfactants and certain detergent ingredients in laundry waters.

COBISS.SI-ID: 11610134Textile hygiene is especially important for hospital textiles, because the patients, that are in the hospital bed most of the time, should not be unnecessarily exposed to harmful microorganisms. Laundries are the greatest consumers of detergents; therefore it is necessary to dedicate emphasis to this field, especially from an ecological view. In the project thermal laundering procedures were tested and chemo-thermal laundering procedures were implemented in laundries for hospital textiles in Slovenia and Croatia.

COBISS.SI-ID: 12074262The European directive 2000/60/EG had to be implemented by 2003. This directive forces all companies to realize extensive measures regarding the minimization of water consumption. European laundries are affected by this because their total costs are influenced by costs of water, energy and detergents. Specific training modules regarding the introduction of sustainable laundering processes were developed wihin this Leonardo da Vinci-project. The current knowledge about modern laundering processes regarding water-, detergent- and energy consumption as well as water reuse measures was presented.
D.06 Final report on a foreign/international project
COBISS.SI-ID: 12073750The hygiene level of hospital textiles and textiles from the food-processing industry were evaluated using German RAL-GZ 992 quality assurance system, European standard RABC and HACCP-principles in Slovenian laundries, determining total bacteria count, and enterobacteria count at control points (CP) in Danish laundries and aerobic, coliform and E.coli count at CP in Norwegian laundries. Using regular cleaning and disinfecting measures by all staff members and achieving a disinfection effect of laundering procedures are most important in achieving an appropriate hygiene level in laundries.

COBISS.SI-ID: 12584470The aim of this investigative study was to determine the presence of rotaviral RNA at various control points of a hospital laundry. In addition, rotavirus suspensions were inoculated on marked surfaces as positive controls for different surfaces (cotton textiles, folding table and industrial dryer). The results show that rotaviral RNA was found in wastewater after the washing process and on various laundry surfaces. Rotaviral RNA was also detected at all positive controls on tested surfaces after 24 h.
