عنوان انگلیسی The Effect of Different Nanoparticles on Dyed Wool Carpet with Walnut Shell Natural Dye
چکیده انگلیسی مقاله Nowadays, research on handmade carpet is developing. It is very important to protect dyed fibers by natural dyes in handwoven woolen carpets against harmful environmental bacteria. In this study, the effect of different nanoparticles on dyed woolen carpet has been investigated. Wool yarns were mordanted with alum 10 % and acetic acid 2 % and then dyed with 60 % walnut natural dyes. After dyeing, carpet was woven and finally was treatment in three steps with three types of particles (nano-silver, nano-titanium dioxide and nano-alumina oxide). SEM, FTIR, color value and color strength, self-cleaning, moisture absorption time, the size of the contact angle, anti-odor property and anti-bacterial activities of dyed wool carpet are investigated. The results showed that the hydrophilic properties of samples have been improved. SEM images indicated the presence of nanoparticles on samples. Also, antibacterial properties of samples against E. coli and S. aureus were very good evaluated. Moreover, Long-term static loading was applied on the sample to make the pile up before and after loading.
