“…In particular, the use of Ag nanoparticles (Ag-NPs) has been advocated for several reasons including the possibility to avoid discoloration, which occurs when ionic Ag is used (Vigneshwaran et al, 2007), negligible impact on fabric breathability and handling (Wong et al, 2006) and an overall smaller environmental impact (Windler et al, 2013). Due to the increased production of Ag functionalized textiles, these materials are one of the major sources of Ag-NPs release to the environment (Mueller and Nowack, 2008;Gottschalk et al, 2009;Arvidsson et al, 2011).…”

“…The industrial use of ZnPT is more common as anti-dandruff in shampoo and soap, and in body wash due to its low water solubility, lack of color and odor when applied in cosmetics [7][8][9] . As antifungal and antibacterial, this substance has been used in paints 10 , textiles 11 and polymeric matrices as polyurethane foam 6 and polyvinyl chloride (PVC) 12 . The biocide action of ZnPT relies on the inhibition of membrane transport and efflux pumps of microorganisms taunting the accumulation of toxic substances inside the cells 13,14 .…”

The purpose of the present study was to evaluate the antimicrobial potential of styrene-ethylene/ butylene-styrene based thermoplastic elastomers (TPE) incorporated with zinc pyrithione (ZnPT) and silver nanoparticles (AgNano). Japan Industrial Standard was applied to evaluate the antimicrobial potential of incorporated TPE compounds against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Antifungal action was evaluated against Aspergillus niger, Candida albicans and Cladosporium cladosporioides. Samples prepared with ZnPT eliminated 99.9% of the E. coli and 99.7 % of the S. aureus population, and presented an inhibition zone in the fungal assay. Samples prepared with AgNano eliminated 99.7% of the E. coli and 95.5 % of the S. aureus population. There was no inhibition zone in samples containing AgNano; however, these samples did not present fungal growth on their surfaces. TPE samples containing ZnPT showed biocidal activity against the microorganisms tested and can be used to develop antimicrobial products.

Abstract:Cotton has widespread applications in textile industries due its interesting physicochemical properties. The objective of this study was to investigate the influence of biofield energy treatment on the spectral, and thermal properties of the cotton. The study was executed in two groups namely control and treated. The control group persisted as untreated, and the treated group received Mr. Trivedi's biofield energy treatment. The control and treated cotton were characterized by different analytical techniques such as differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), fourier transform infrared (FT-IR) spectroscopy, and CHNSO analysis. DSC analysis showed a substantial increase in exothermic temperature peak of the treated cotton (450 ºC) as compared to the control sample (382ºC). Additionally, the enthalpy of fusion (∆H) was significantly increased by 86.47% in treated cotton. The differential thermal analysis (DTA) analysis showed an increase in thermal decomposition temperature of treated cotton (361ºC) as compared to the control sample (358ºC). The result indicated the increase in thermal stability of the treated cotton in comparison with the control. FT-IR analysis showed an alterations in -OH stretching (3408→3430 cm -1 ), carbonyl stretching peak (1713-1662 cm -1 ), C-H bending (1460-1431 cm -1 ), -OH bending (580-529 cm -1 ) and -OH out of plane bending (580-529 cm -1 ) of treated cotton with respect to the control sample. CHNSO elemental analysis showed a substantial increase in the nitrogen percentage by 19.16% and 2.27% increase in oxygen in treated cotton as compared to the control. Overall, the result showed significant changes in spectral and thermal properties of biofield energy treated cotton. It is assumed that biofield energy treated cotton might be interesting for textile applications.
