Benchtop NMR Analysis for Fibers and Textiles
Coated textiles are materials that have undergone a specialized treatment process. This process involves applying unique technologies to imbue fabrics with distinctive properties, thereby enhancing their functionality. These treated fabrics are often referred to as functional coated fabrics or textiles.
Fluorinated coatings are widely employed in fibers and textiles to impart attributes such as oil resistance, water resistance, ease of cleaning, and flame retardancy. They find applications in diverse areas like carpets, outdoor products, and performance apparel. Precisely controlling the quantity of fluorinated coating is of paramount importance. By managing the fluorinated coating content effectively, the manufacturing process can be optimized, leading to superior product performance. Benchtop Nuclear Magnetic Resonance (NMR) emerges as a rapid, straightforward, and accurate tool for measuring fluorinated coatings.
Benchtop NMR Measurement Principle
The benchtop NMR analysis technique revolves around the direct measurement of the nuclear magnetic resonance (NMR) signal of fluorine-19. As the fluorine content correlates directly with the intensity of the detected NMR fluorine signal, the fluorine content (expressed as wt%) can be deduced using an appropriate calibration curve.
Benchtop NMR Measurement Methods
After calibration with 3 to 6 samples possessing known fluorine content, unidentified samples can be analyzed within a mere 30 to 3 minutes. The Benchtop NMR testing process is swift and non-destructive, making it amenable to real-time industrial process monitoring.
Compared to conventional chemical methods, Benchtop NMR exhibits superior reproducibility, obviates the need for chemical solvents, and can be carried out by personnel without specialized training.
