The invention relates to a process for the preparation of self-cleaning wash-resistant and air-permeable superhydrophobic and oleophobic cotton textiles. The coating is applied to the surface of the cotton textile and results in sliding angles for water that are lower than 10 degrees, even after 10 washings. The coatings consist of differently sized premade siloxane particles and particles grown in-situ in the presence of cotton textiles. The in-situ preparation of siloxane particles provides a bi-hierarchical surface roughness and a good connection between the siloxane particles and the textile, which is further strengthened by the use of fluorinated alkoxy silanes. The combination of the proposed solution enables improved wash-resistant properties for the coatings. This achievement is of high importance for the textile industry because it enables the preservation of the functional properties after repetitive washing. This added value can increase the market competitiveness of biodegradable cotton and improve the competitiveness of the European market. The achievement was presented on 30.1.2019 in Vienna at the Start: IP event, where technology-based business ideas are presented to entrepreneurs which is the first step in the commercialisation of academic and industrial research.

COBISS.SI-ID: 3230576The invention relates to a method for the preparation of a polyamide 6 copolymer. It relates to a polyamide 6 copolymer thus obtained, to the use thereof for the production of filaments or fibres of polyamide 6, and to filaments and filament yarns of polyamide 6 thus obtained. The invention relates to the production process of recyclable flame retardant (FR) polyamide 6 fibres with the incorporated ?-caprolactam based flame retardant functionalised comonomers which enables a closed loop recycling. It can be used in the field of polyamide 6 technical textiles and engineering plastics which represent the largest and the fastest-growing segments of the global polyamide market. This achievement is of high importance for the industry which produces polyamide 6 textile materials for automobiles, trains and airplanes as well as carpets in public buildings, where materials must fulfil the requirements dictated by the certain flame retardancy standards. This would also significantly contribute to the increase of the lives and property protection. The production of this high added value material can increase the market competitiveness of this chemically recyclable polymer as well as the competitiveness of the European market. This invention was presented on 26. 10. 2018 in the Innovation Day, which was held in Brdo pri Kranju and was aimed to connect innovators and the economy. Furthermore, this invention was presented on 30.1.2019 in Vienna at the Start: IP event, where technology-based business ideas are presented to entrepreneurs which is the first step in the commercialisation of academic and industrial research.
F.32 International patent
COBISS.SI-ID: 3584624Object of the presented invention belongs to the field of secondary packaging for storing foods, for which it is desirable to control their temperature before consumption. The invention refers to the cardboard packaging made of a multi-layered cardboard, where the incorporated printed temperature sensor allows the end user to determine the appropriate temperature before food consumption. More precisely, it is a temperature (resistor) sensor, printed with the conventional or digital printing technology and is placed at the bottom of the smart packaging under the protective laminating heat resistant layer. Innovation is a printed temperature sensor, while the measurement system is based on conventional electronics. The sensor itself is not tied to the measuring system type, and it can be upgraded with a system for the radio frequency communication. There are many benefits of printed sensors. The production of sensors is environmentally friendlier compared to the existing technologies, where sensors are mostly manufactured according to the subtractive mode (etching or hot conductive foil printing). Printing technologies, however, make it possible to print sensors in an additive mode, which means a great saving in the consumption of conductive materials; printing inks and foils. Based on the current state of the art, we have confirmed many advantages of the process of producing printed temperature sensors for the purpose of using smart packaging according to the described invention. Main advantages are the simplicity and reliability of the process and its cheaper or faster realization, while adding interactivity and high added value to the final product - packaging, as they increase or expand its usefulness. In accordance with the international classification of patents, the invention is classified into the group B65D.

COBISS.SI-ID: 382912BOH PODGORNIK, Bojana, HRIBERNIK, Silvo, ŠUMIGA, Boštjan. CEL.CYCLE: Potential of biomass for development of advanced materials and bio-based products: D 2.1.3.3 Three optimized microcapsulation processes for selected active ingredients - prototypes: Ljubljana, 30.11.2018. Ljubljana: Republic of Slovenia, Ministry of Education, Science and Sport, 2018. 14 p. [COBISS.SI-ID 1443934]. Three prototypes of microencapsulation processes were developed, to encapsulate the selected antimicrobial substance - essential oil of Cymbopogon citratus - citronella oil: (1) in situ polymerization of melamine-formaldehyde precondensates and polyacrylic acid as a modifier, (2) emulsification and solvent evaporation to produce microcapsules with ethylcellulose walls, (3) complex coacervation microencapsulation of gelatin and carboxymethylcellulose or gum arabic. The achievement enables the incorporation of microcapsules into functional coatings or into printing formulations, and is particularly applicable for the paper and textile industries to increase the added value of products and to achieve multifunctional properties. The achievement was presented as a lecture at the International Meeting Paper in the Digital Age [COBISS.SI-ID 1444190].

COBISS.SI-ID: 1443934Members of the Programme group P2-0213 organise scientific symposia on Novelties in Textiles (SNT), which are carried out every year at the Department of Textiles, Graphic Arts and design, Faculty of Natural Sciences and Engineering, University of Ljubljana. We act as the presidents of the organizing and scientific committees of the symposia as well as the editors of the symposia proceedings (C.01). Symposia represent a textile platform that enables participants to present and discuss the latest achievements, new perspectives and guidelines. They offer an important link between research institutions and the economy. In 2010, the Programme group members organised the 41st International Symposium on Novelties in Textiles and the 45th International Congress IFKT, which were carried out from 27 to 29 May, 2010 in Ljubljana simultaneous with the 5th International Symposium on Novelties in Graphics. 268 participants from 30 countries attended the symposiums. Scientific programme of the symposiums included 9 plenary lectures, 79 lectures and 111 posters. Barbara Simončič and Alenka Pavko Čuden were the chairs of the Scientific committees. Members of the Programme group also organised the 16th World Textile Conference Autex 2016, which was held from 8–10 June 2016 in Ljubljana, Slovenia. The AUTEX Conference is one of the most important scientific events in the field of textiles aimed to bring together leading researchers, experts, students and people from the industry from all over the world to share their knowledge and exchange scientific ideas. At the conference, 285 contributions were presented as oral and poster presentations. Andrej Demšar was the chair of the Organising committee, Barbara Simončič was the chair of the Scientific committee, and Barbara Simončič, Brigita Tomšič and Marija Gorjanc were editors of the conference Proceedings. In 2018, we chaired the program committee (Aleš Hladnik) and were members of the program and organizing committees (Deja Muck, Bojana Boh Podgornik, Diana Gregor Svetec) of 8th Conference on Information and Graphic Arts Technology which were carried out 7-8 June 2018 Ljubljana, Slovenia.
