Functionalization of textile materials with bioactive polymeric systems based on propolis and cinnamon essential oil

Abstract

In order to obtain the textile materials with potential for use in the treatment of inflammatory skin conditions, this study approached the laboratory experiments related to depositing by padding of oil-in-water emulsions type based on chitosan-propolis-cinnamon essential oil. In this regard, seven experimental variants of emulsions were prepared and then characterized by specific methods from physical-chemical and stability point of view. The chitosan-propolis- cinnamon essential oil-based emulsions were then immobilized on a knitted textile structure from 100% organic cotton. The functionalized textile materials were characterized from morphological and antibacterial activity point of view. pH values obtained for the synthesized polymeric systems were in the range 4.67–4.88 and electrical conductivity of the emulsions increases with the concentration of the hydrophilic phase in the system, the highest values were registered for the emulsion code R4CSP developed with the smallest volume fraction of water. The stability index over a period of 10 days indicated that emulsions are stable, not showing the presence of one of the flocculation, creaming / sedimentation, coalescence or Ostwald ripening phenomena. The highest values of emulsifying activity index were obtained for the R7CSP, emulsion developed with the smallest volume fraction of water. The highest value of viscosity was obtained for the experimental variant R4CSP in which the highest volume fraction of chitosan and the smallest volume fraction of water were used. The textile materials treated with synthesized emulsions based on chitosan- propolis-cinnamon essential oil have antibacterial effect against the S. aureus test strain, with inhibition zones between 1.5 mm (R2CSP and R7CSP) and 4 mm (R6CSP).

Formation and Investigation of Mechanical, Thermal, Optical and Wetting Properties of Melt-Spun Multifilament Poly(lactic acid) Yarns with Added Rosins

“…Similar results can be seen in multifilaments containing natural compounds with myrrh and polymeric film containing cinnamon oil, myrrh, and rosin. After modifying multifilament yarns with natural compounds, the films also showed lower reflectance in the UV region [17,36,47]. The presence of compounds introduced into PLA multifilament yarns through the addition of rosin (i.e., B, C, E, and F) indicates a significant increase in absorption (and a decrease in diffuse reflection) in the wavelength ranging from 500 to 400 nm as well as broad and intensive absorption bands in the entire UV region (from 200 to 400 nm) of the recorded spectra.…”

“…These compounds demonstrate various biological effects such as antibacterial, anti-inflammatory, or antioxidant effects. Their effect (i.e., biological activity) can be used in the medical field by incorporating these materials in medical textiles [17]. Natural compounds are already added to polymer film such as coffee, cacao, basil oil extract, oregano, and cinnamon oil [18][19][20][21].…”

Comparative study of multifunctional properties of synthesised ZnO and MgO NPs for textiles applications

“…Furthermore, application of nanotechnology has demonstrated that conventional textile products can be transformed into materials having an entirely new set of properties with an overall enhancement in the functionality too (Yuranova et al , 2006). To achieve the desired functionality, a range of materials from polymeric products (Chirilă et al , 2020; Tadesse et al , 2020) to metals in different forms (Balci et al , 2014) are reportedly used.…”

Immobilization of functional biomolecules onto polypropylene fabric using plasma pre-treatment

“…Biological macromolecules are non-toxic and degradable with natural biocompatibility, which become new materials resources for the development and utilization as functional agents. 17,18 Many biological macromolecules, including collagen, chitosan, and sericin, have been widely applied in the medical and cosmetics industry. [19][20][21][22][23][24][25] Collagen is a kind of macromolecular protein found in skin, blood vessels and bones, which obtained from different animals has good health function.…”
