摘要

•13C CP-MAS NMR can be used to reliably quantify the composition of cellulose and polyester in textile blends.•Sigmoidal calibration functions describe the correlation between cellulose and polyester signals in the NMR spectrum.•It is also possible to apply solid-state NMR to determine the crystallinity of cellulose in cotton polyester blended textiles.
