Abstract
Novel 1,3-bis[(furan-2-yl) methylene]thiourea (BFMT) dye was synthesized from condensation reaction between sugarcane bagasse derived furfural and thiourea. The synthesized BFMT dye was characterized by physicochemical (melting point and CHN) and spectrometry (UV–Vis, FTIR, 1H-NMR and 13C-NMR) analyses. The synthesized BFMT dye was screened for its antimicrobial (antibiotic and antifungal) properties. BFMT dye was applied on wool and cotton fabrics. The functional properties of BFMT dyed fabrics (color value, color strength, fastness properties, antimicrobial activities, ultraviolet protection factor (UPF), and mechanical properties) were assessed. Chemical composition of synthesized BFMT dye was determined by CHN analyzer, while its structure was confirmed by FTIR and NMR spectrometry analyses. BFMT dye solution showed reddish brown complementary color with λmax 485 nm on UV–Visible spectrophotometer. The antibiotic property of the synthesized dye was moderate, while antifungal property was excellent on tested microorganisms. BFMT dyed wool and cotton fabrics displayed good mechanical properties, air permeability, water vapor permeability and wetability. Dyed fabrics possessed excellent exhaustion (> 80%), fastness properties, ultraviolet protection factor (UPF > 40) and fungal growth inhibition rate (> 70%).
