Molecular mobility in the superstrong para-aramid fibre—water system

  • Published:
Fibre Chemistry Aims and scope

The state of the components in the para-aramid fibre—water system was investigated by NMR and sorption methods. The correlation of the parameters of the sorption isotherm and NMR spectra was demonstrated. In the fibres investigated, water molecules sorbed by the Rusar sample had the lowest mobility and water molecules sorbed by the Technora sample had the highest mobility. The low values of T2k of Rusar fibre suggest strong bonding of the sorbate with the sorbent, which indirectly confirms the low crystallinity and high chain orientation in this fibre.
