1. A review of electro conductive textiles utilizing the dip-coating technique: Their functionality, durability and sustainabilityAlenka Ojstršek, Laura Jug, Olivija Plohl, 2022, pregledni znanstveni članek Opis: The presented review summarizes recent studies in the field of electro conductive textiles
as an essential part of lightweight and flexible textile-based electronics (so called e-textiles), with the
main focus on a relatively simple and low-cost dip-coating technique that can easily be integrated
into an existing textile finishing plant. Herein, numerous electro conductive compounds are discussed, including intrinsically conductive polymers, carbon-based materials, metal, and metal-based
nanomaterials, as well as their combinations, with their advantages and drawbacks in contributing
to the sectors of healthcare, military, security, fitness, entertainment, environmental, and fashion,
for applications such as energy harvesting, energy storage, real-time health and human motion
monitoring, personal thermal management, Electromagnetic Interference (EMI) shielding, wireless
communication, light emitting, tracking, etc. The greatest challenge is related to the wash and wear
durability of the conductive compounds and their unreduced performance during the textiles’ lifetimes, which includes the action of water, high temperature, detergents, mechanical forces, repeated
bending, rubbing, sweat, etc. Besides electrical conductivity, the applied compounds also influence
the physical-mechanical, optical, morphological, and comfort properties of textiles, depending on
the type and concentration of the compound, the number of applied layers, the process parameters,
as well as additional protective coatings. Finally, the sustainability and end-of-life of e-textiles are
critically discussed in terms of the circular economy and eco-design, since these aspects are mainly
neglected, although e-textile’ waste could become a huge problem in the future when their mass
production starts.

2. Obtaining medical textiles based on viscose and chitosan/zinc nanoparticles with improved antibacterial properties by using a dielectric barrier dischargeMatea Korica, Ana Kramar, Zdenka Peršin Fratnik, Bratislav M. Obradović, Milorad Kuraica, Biljana Dojčinović, Lidija Fras Zemljič, Mirjana M. Kostić, 2022, izvirni znanstveni članek Opis: This study aimed to obtain functional viscose textiles based on chitosan coatings with
improved antibacterial properties and washing durability. For that reason, before functionalization
with chitosan/zinc nanoparticles (NCH+Zn), the viscose fabric was modified by nonthermal gas
plasma of dielectric barrier discharge (DBD) to introduce into its structure functional groups suitable
for attachment of NCH+Zn. NCH+Zn were characterized by measurements of hydrodynamic diameter and zeta potential and AFM. DBD-plasma-modified and NCH+Zn-functionalized fabrics were
characterized by zeta potential measurements, ATR-FTIR spectroscopy, the calcium acetate method
(determination of content of carboxyl and aldehyde groups), SEM, breaking-strength measurements,
elemental analysis, and ICP-OES. Their antibacterial activity was determined under dynamic contact
conditions. In addition to SEM, the NCH+Zn distributions on viscose fabrics were also indirectly characterized by measuring their absorbent capacities before and after functionalization with NCH+Zn.
Washing durability was monitored through changes in the zeta potential, chitosan and zinc content,
and antibacterial activity after 1, 3, and 5 washing cycles. The obtained results showed that DBD
plasma modification contributed to the simultaneous improvement of NCH+Zn sorption and antibacterial properties of the viscose fabric functionalized with NCH+Zn, and its washing durability,
making it suitable for the production of high-value-added medical textiles.

3. Decontamination efficiency of thermal, photothermal, microwave, and steam treatments for biocontaminated household textilesBranko Neral, Selestina Gorgieva, Manja Kurečič, 2022, izvirni znanstveni članek Opis: With the outbreak of the COVID-19 pandemic, textile laundering hygiene has proved to be
a fundamental measure in preventing the spread of infections. The first part of our study evaluated
the decontamination efficiency of various treatments (thermal, photothermal, and microwave) for
bio contaminated textiles. The effects on textile decontamination of adding saturated steam into
the drum of a household textile laundering machine were investigated and evaluated in the second
part of our study. The results show that the thermal treatment, conducted in a convection heating
chamber, provided a slight reduction in efficiency and did not ensure the complete inactivation of
Staphylococcus aureus on cotton swatches. The photothermal treatment showed higher reduction
efficiency on contaminated textile samples, while the microwave treatment (at 460 W for a period of
60 s) of bio contaminated cotton swatches containing higher moisture content provided satisfactory
bacterial reduction efficiency (more than 7 log steps). Additionally, the treatment of textiles in the
household washing machine with the injection of saturated steam into the washing drum and a mild
agitation rhythm provided at least a 7 log step reduction in S. aureus. The photothermal treatment
of bio contaminated cotton textiles showed promising reduction efficiency, while the microwave
treatment and the treatment with saturated steam proved to be the most effective.

5. Dioxins and dioxin-like persistent organic pollutants in textiles and chemicals in the textile sectorBoštjan Križanec, Alenka Majcen Le Marechal, 2006, pregledni znanstveni članek Opis: Over ▫$7x10^5$▫ tons of dyestuff is produced annually with more than 100.000 commercially available dyes. Synthesis of colorants involves a relatively large group of chemicals with complex syntheses. During the synthesis of colorants, highly toxic, cancerogenic and persistent organic compounds, such as dioxins, can be formed. Dioxins are related to halogenes, chlorine and bromine homologues being the most toxic and persistent. About 40% of globally used colorants contain organically bound chlorine. The use of colorants in textile industry, with their wide applications and complex chemistry could be a significant source of dioxins and/or precursor compounds for the formation of dioxins and other persistent organic pollutants. The aim of the paper is to give an overview of the dioxin-like compounds in chemicals, with emphasis on colorants, textiles and their fate in the environment.

6. Comparison of methods for detection of four common nosocomial pathogens on hospital textilesSabina Fijan, Sonja Šostar-Turk, Urška Rozman, 2014, izvirni znanstveni članek Opis: Introduction: Although the most common vehicle for transmission of health-care acquired infections is the personto- person transmission route, the role of environment should not be ignored and hospital linen may contribute to the spreading of nosocomial infections. The contact plate method and swabbing are common methods for sampling microorganisms on textiles; however, results are available after two days as they are based on incubation followed by phenotypeidentification. An important alternative is using quick wash-off methods followed by PCR detection, which shortens the identification process from two days to a few hours.
Methods: The following test microorganisms at different concentrations were inoculated onto textile swatches and dried overnight: Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and Clostridium difficile. RODAC plate sampling as well as a non-destructive wash-off method for capturing microorganisms from the textilesusing a Morapex device were used. The elution suspension from the Morapex device was used for two methods. In the first method, classical incubation on selective media followed by phenotypic identification was used and in the second method DNA was extracted from the elution suspension followed by amplification and agarose gel electrophoresis to visualize amplified products.
Conclusions: All chosen bacteria were found using all methods. However, the most sensitive proved to be detection using PCR amplification as we detected the sample with initial concentration of 102 cfu/mL inoculated onto the textile surface before drying. The final detectablerecovered bacterial concentration on textiles was up to 10 cfu/mL.

8. Real-time polymerase chain reaction for quantitative assessment of common pathogens associated with healthcare-acquired infections on hospital textilesUrška Rozman, Sabina Fijan, Sonja Šostar-Turk, Vid Mlakar, 2013, izvirni znanstveni članek Opis: A hospital environment may act as a significant reservoir for potential pathogens that can be transmitted with hospital textiles, which could represent a source of healthcare-acquired infections. Quantitative assessment of nosocomial pathogens with real time polymerase chain reaction (qPCR) on textiles can serve to verify the achievement of standards for textile hygiene of hospital laundry that assess the risk for acquiring hospital infection frominappropriately disinfected textiles. The aim of the study was to establish qPCR for quantitative assessment of selected common nosocomial pathogens (Clostridium difficile, Staphylococcus aureus, Klebsiella pneumoniaeand Pseudomonas aeruginosa) on hospital textiles and to compare the efficiency of the molecular method to the standard procedures for evaluating the bio burden of textiles in hospitals. This study demonstrated that presenceof nosocomial pathogens on hospital textiles can be confirmed with qPCR even where conventional techniques do not give any results. qPCR offers apossibility to confirm the presence of microorganisms in dead or viable but non-culturable states that cannot be detected by conventional sampling techniques but may still pose a hazard to public health.

9. Computer simulation of needle and take-up lever mechanism using the ADAMS software packageDarja Žunič-Lojen, Karl Gotlih, 2003, izvirni znanstveni članek Opis: A knowledge of the interactions between a sewing machinećs mechanisms and the sewing thread in the stitch formation process should help us to understand thread loadings in the sewing process. The aim of this work is to analyse the needle bar's kinematics with the thread take-up lever by using computer simulation. A cyclogram was drawn on the basis of modelling and kinematic simulation of a needle bar with a thread take-up lever, and measurements of the thread tension forces in the sewing process. This cyclogram enables analysis of the interactions between the thread and the elements of the sewing machine. The results of these simulations are curves that describe the movements at characteristic points on the mechanism. These give the possibility of pinpointing the exact positions of the mechanism's elements with respect to the main shaft rotation in the sewing machine.

10. The influence of structural properties on the dye diffusion and dyeability of PA 6 fibresSimona Strnad, Slava Jeler, Karin Stana-Kleinschek, Tatjana Kreže, 2003, izvirni znanstveni članek Opis: The relationships were investigated between the structural and dyeing properties of different structurally modified PA 6 fibers. PA 6 monofilament yarn samples were applied having different crystalline degrees and different content of alpha, respectively gamma crystalline modification. The diffusion coefficients of two different acid dyes were determined together with the content of dyestuff absorbed (under specific conditions) by fiber samples. In order to estimate colorimetry method from the viewpoint of polymer structural change detection, the colors of the dyed PA 6 samples were determined (L*, a*,b*, C*, h coordinates) and the color differences (L*, a*, b*, C*, H*, E*) were calculated between untreated standard and structurally modified samples. The dyeability of PA 6 fibers depended mainly on the way in which crystallinity had been achieved, i.e. on the materialćs history. Different crystalline modifications caused different sorption properties and fiber dyeability. Smaller increases (app 20%) of crystallinity degree caused a decrease in diffusion coefficients. Contrary to expectations, the significant increase of crystallinity degree (app 50%) had an influence on the increase ofdyeability, presumably owing to the formation of larger empty spaces in the structure. The results achieved by colorimetry were in good correlation with dye absorption measurements. The colorimetry of dyed fiber samples was sensitive enough to detect even small differences in the quantities of absorbed dyestuff.
