Structure investigation of lyocell fibres by in situ USANS measurements

Abstract : Lyocell fibres nowadays are widely used in textile production and have an enormous potential for various technical applications. The structure of these fibres, however, is a pending research issue. Particularly, the process of fibrillation is still to be understood and a major issue for the optimisation of the production process. Now, first experiments with neutrons using USANS technique have revealed indications about the fibre structure in the micrometer range. We observed clear ultra-small-angle scattering patterns from even small numbers of fibres after spinning and even from inside the spinning bath during the spinning process. The outer diameter of the fibres is well reproduced in the scattering patterns which also indicate the presence of smaller internal structure. First experimental results obtained at the S18 instrument at the ILL are presented.
