“…The aim of this research was, thus, to integrate hexamethylenediamine (HMDA) functionalized CNFs (CNF-HMDA; Jin et al 2015;Vivod et al 2019) into viscose yarn, produced by a conventional ring-spinning process, to obtain a yarn with antimicrobial properties, being related to the HMDA surface attached to the CNFs. Diamines as HMDA have been used as functional monomers to design amine-terminated nanocellulose (Hemraz et al 2013) or polymers (Gün Gök et al 2020) with antimicrobial properties to be applied in the preparation of hygenic paper products (Xiao and Qian 2014), biopolymers for biomedicine (Hemraz et al 2013;Gün Gök et al 2020;Alamri et al 2012), and products for biological water tretment (Alamri et al 2012). However, because HMDA may have minimal impact on overall toxicity (Harper et al 2016), although its leaching from CNF-HMDA is unlikely due to its covalent linkage, we performed skin irritation testing of CNF-HMDA on rabbits to verify its potentially harmful effect on skin contact.…”

Bio-based, renewable and biodegradable products with multifunctional properties are also becoming basic trends in the textile sector. In this frame, cellulose nanofibrils (CNFs) have been surface modified with hexamethylenediamine/HMDA and used as an antimicrobial additive to a ring-spun viscose yarn. The CNF-HMDA suspension was first characterized in relation to its skin irritation potential, antimicrobial properties, and technical performance (dispersability and suspensability in different media) to optimize its sprayability on a viscose fiber sliver with the lowest sticking, thus to enable its spinning without flowing and tearing problems. The impact of CNF-HMDA content has been examined on the yarn`s fineness, tensile strength, surface chemistry, wettability and antimicrobial properties. The yarn`s antimicrobial properties were increasing with the content of CNF-HMDA, given a 99% reduction for S. aureus and C. albicans (log 1.6–2.1) in up to 3 h of exposure at minimum 33 mg/g, and for E. coli (log 0.69–2.95) at 100 mg/g of its addition, yielding 45–21% of bactericidal efficacy. Such an effect is related to homogeneously distributed CNF-HMDA when sprayed from a fast-evaporated bi-polar medium and using small (0.4 mm) nozzle opennings, thus giving a high positive charge (0.663 mmol/g) without affecting the yarn`s tenacity and fineness, but improving its wettability. However, a non-ionic surfactant being used in the durability testing of functionalized yarn to 10-washing cycles, adheres onto it hydrophobically via the methylene chain of the HMDA, thus blocking its amino groups, and, as such, decreasing its antibacterial efficiency, which was slightly affected in the case when the washing was carried out without using it.

“…Moreover, due to its own porosity PET is conducive to microbial adhesion and subsequent bacteria colonization [16]. Therefore, for improvement of antimicrobial properties PET was subjected to several surface modification technologies [17,18], the majority based on functionalization [19,20], grafting [21][22][23][24][25][26][27][28], surface topography modification [29][30][31][32][33], coating [34][35][36][37] and their combinations [38][39][40].…”

Deposition of Copper on Polyester Knitwear Fibers by a Magnetron Sputtering System. Physical Properties and Evaluation of Antimicrobial Response of New Multi-Functional Composite Materials

et al. 2020

In this study, copper films were deposited by magnetron sputtering on poly(ethylene terephthalate) knitted textile to fabricate multi-functional, antimicrobial composite material. The modified knitted textile composites were subjected to microbial activity tests against colonies of Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria and antifungal tests against Chaetomium globosum fungal molds species. The prepared samples were characterized by UV/VIS transmittance, scanning electron microscopy (SEM), tensile and filtration parameters and the ability to block UV radiation. The performed works proved the possibility of manufacturing a new generation of antimicrobial textile composites with barrier properties against UV radiation, produced by a simple, zero-waste method. The specific advantages of using new poly(ethylene terephthalate)-copper composites are in biomedical applications areas.
