| Abstract: | A new method of low-field pulsed nuclear magnetic resonance (NMR) spectroscopy for the determination of spin finish in cellulose acetate tow was investigated. Five standards for the establishment of working cusve were standardized by Soxhlet extraction with the spin finish content in range of 0.68%~1.73%, uncertainty of the determination was assessed. The method is suitable for the routine analysis of spin finish in cellulose acetate tow with the advantage of non-pollution and non-damage. |
