Polypropylene (PP) fabrics were activated by an atmospheric pressure, dielectric barrier discharge to optimize the effects
of some discharge parameters on the dyeability of PP fabrics. Air and argon plasmas were used to modify the surfaces of the
fabrics, and the effects on dyeability were investigated when the treated fabrics were dyed by leuco and pigment forms of
vat dyestuffs. Surface properties of plasma-treated samples were characterized by Fourier transform infrared spectroscopy
(FTIR-ATR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Vat-dyed samples showed a significant
increase in color strength when PP fabrics were pretreated with atmospheric pressure plasmas of either argon or air. 相似文献

The dyeing properties of the polypropylene (PP) fabrics using cationic dyestuffs were investigated after surrounded air atmospheric cold-plasma treatment. Surrounded air plasma (SAP) was used to modify fabric surface and to optimize the effects of some discharge parameters on dyeability. Surface morphology and physical-chemical properties of plasma treated fibers were also characterized by Fourier transform infrared attenuated total reflection spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. Activated surfaces by SAP were grafted with different compounds: 6-aminohexanoic acid, acrylic acid, and hexamethyldisiloxane. Dyeing the plasma-induced grafted PP fabric with basic dye was quite satisfactory when high color strength and good fasteness were considered. 相似文献

The in vitro antimicrobial activity of Ankaferd Blood Stopper (ABS) was assessed on 102 clinical isolates from both Gram negative and Gram positive bacteria and four standard strains, including MRSA ATCC 43300, MSSA ATCC 25923, P. aeruginosa ATCC 27853 and E. coli ATCC 35218. ABS was significantly active against all bacteria investigated. 相似文献

Organic-inorganic hybrid coatings containing phosphoric acid (PA) bonded to the organic-inorganic network were prepared from
tetraethoxysilane (TEOS) using a sol-gel process. The effect of sol-gel phosphate-based flame retardant coating on polyacrylonitrile
fabric properties (flammability, stiffness, and strength) was investigated. Sample characterization of the coated samples
were investigated using differential thermal/thermogravimetric analysis (DTA/TGA), Fourier transform infrared spectroscopy
(FTIR), X-ray diffractometer (XRD), and scanning electron microscopy (SEM). The results showed that hybrid coating on the
polyacrylonitrile fabrics influenced fabric stiffness, strength, and flammability. And also, flammability of the coated samples
after washing cycles was investigated, and the flame retardancy properties of the samples after 10 repeated washings were
not completely lost. 相似文献
