Abstract
To use cellulosic sustracts in the textile sector are necessary treatments like mercerization, laundering, etc.., These treatments originate structural changes that in several times gives crystallinity changes. By means Fourier Transformer Infrared Spectroscopy and using the Indexes of Total Crystallinity (ICT) and Lateral Order (IOL) proposed by Nelson and O'Connor it has been observed that during the oxidation treatment with H2O2, ramie and flax fibers increase the ratio of crystallized cellul...
