Abstract

The average lateral fibril aggregate dimensions and the crystallinity of the cellulose in a spruce kraft pulp were analysed by CP/MAS ¹³C-NMR spectroscopy in combination with spectral fitting. The average lateral fibril and lateral fibril aggregate dimensions were calculated from quantitative spectra of pure cellulose isolated from kraft pulps. Results showed that cellulose isolated by acid hydrolysis and chlorite-delignification from fines fraction enriched in surface material and long fiber fractions enriched in bulk material exhibited no major difference in either lateral dimension or crystallinity index.
