Abstract
The aim of this study is to investigate the effect of extraction treatment method on the properties of WPF (Washingtonia palm fibres). The employed treatment is a combined mechanical and chemical sodium hydroxide. The treatment processes was described and evaluated. The physical properties (linear density, diameter and extraction yield), and the mechanical properties (tenacity) of WPF were measured. The optimum extraction condition has been determined by a statistical, study using desirability function. Obtained fibres under optimal conditions were characterized with morphological test (SEM), chemical tests (FT-IR spectra, X ray diffraction) and thermal test (TGA). Fibre obtained can be employed on technical textile applications and in particular drylaid nonwoven.
