Benchtop NMR Measurement of Fluorinated Coatings on Fibers and Textiles

Benchtop NMR Measurement of Fluorinated Coatings on Fibers and Textiles

Coated fabrics are fabrics or fabrics that have been treated with a special process. Mainly, on the basis of the cloth, special technology is used to coat materials with special functions, so that the cloth adds special functions. Therefore, it is also called functional coated fabric or cloth.

Fluorinated coatings are commonly used in fibers and textiles to provide oil resistance, water resistance, ease of cleaning and flame retardant properties. Can be used in carpets, outdoor products, and performance apparel. The control of the amount of fluorinated coating is very critical. Controlling the content of fluorinated coating can optimize the process and improve the performance of the product. Benchtop NMR can be used for fast, simple, and accurate measurements of fluorinated coatings.

Benchtop NMR Measurement of Fluorinated Coatings on Fibers and Textiles:

The benchtop NMR analysis technique is based on the direct measurement of the nuclear magnetic resonance (NMR) signal of fluorine 19. Since the fluorine content is proportional to the intensity of the detected NMR fluorine signal, the fluorine content (wt%) can be calculated using an appropriate calibration curve.

Benchtop NMR Measurement Methods for Fluorinated Coatings on Fibers and Textiles:

After calibrating with 3~6 samples with known fluorine content, unknown samples can be tested within 30~3 minutes. The Benchtop NMR testing process is fast and non-destructive, enabling industrial online process testing.

Advantages of benchtop NMR measurements of fluorinated coatings on fibers and textiles:

1. Benchtop NMR measurement test is fast;
2. The calibration of the benchtop NMR measuring instrument is simple;
3. Compared with the traditional method, the benchtop NMR measurement has much better repeatability and reproducibility;
4. Benchtop NMR measurement can be used for quality inspection and quality control in the industrial production process, saving labor and significantly improving efficiency;
5. Benchtop NMR measuring instrument is easy to operate, does not require technical personnel, and is easy to operate by untrained personnel;
6. Benchtop NMR measurement function is powerful, suitable for the fluorine content test of fiber and textile products;
7. Benchtop NMR measurement has no requirements on the shape of the sample, and the sample can be powder, granule, film or block.
8. Benchtop NMR measurement is a non-invasive and non-destructive test, and the same sample can be repeatedly measured as needed;
9. The NMR signal of benchtop NMR measurement is generated by all hydrogen nuclei in the entire sample volume, and the test result does not depend on the sample surface or sample color;
10. Benchtop NMR measurement can be used for 1H content testing in some raw materials and chemical products;
11. Benchtop NMR measurement can be used for oil and water content testing in other chemical products;
