In the world, there are about twenty (20) species among which the Raffia vinifera is found in the West, the Northwest, the South, the Center and the East Regions of Cameroon.
Mechanical studies have been carried out on the long-term creep behavior of the Raffia vinifera stem in compression and flexion tests [10-13].
In the same vein and in the view of improving the scientific knowledge so as to optimize the use of Raffia vinifera, this study focuses on the study of the water absorption phenomenon in the Raffia vinifera pith.
The samples used in this work come from the stem of Raffia vinifera originating from Bandjoun in the West Region of Cameroon particularly the Koung-Khi division.
In each sampling zone, twenty (20) samples were tested for a total of two hundred and forty (240) samples of Raffia vinifera along the stem.
A comparative study of the percentage of the water absorption of the Raffia vinifera pith and other vegetal products has been done, in Table 2.
We distinguish about twenty species of raffia in the world  among which there is the Raffia vinifera. This type of raffia does not contain a trunk  and essentially grows in the bottom of the mountainous and swamp areas.
We notice that the realization of art and craft products such as the baskets, stools, hats, clothing, braces, and beds requires the Raffia vinifera as raw material.
The study on the long-term behaviour of the stem of Raffia vinifera in compression or in flexion was approached [9-12].
In order to improve the knowledge on the Raffia vinifera, we are interested in the hydration phenomenon of these fibres.
The Raffia vinifera fibres on which our study is based come from the stems of Raffia vinifera of the swamp area located at the surrounding of the University Institute of Technology Fotso Victor of Bandjoun in the west region of Cameroon.
