Synopsis

The principle of the spinning whatever the origin of the fibers to be treated a disordered mass of fibers to mix them, clean them of their impurities, parallels them in the form of veil, then of ribbon. This sliver will undergo several successive stretching to make them more homogeneous and regular to transform them into wick which represents the intermediate part between the sliver and the wire.Finally, a last stretching will be given to the wick to which we will apply a torsion to obtain the thread. It is essential that in a batch of yarns the physical and chemical properties are substantially the same at all points and to produce a consistent quality, it is necessary that from one batch to another the characteristics are the same For all these reasons it is necessary to mix the fibers thoroughly, mixtures can be realized in two ways:-by operating on the fibers in flock-by operating on the fibers in sliver Cotton plays an important role in the economic development of sub-Saharan Africa. However, only 15% of the cotton grown in the region is processed locally, with the vast majority being exported as raw material.The United Nations Industrial Development Organization (UNIDO) is engaged in various initiatives to support the African cotton sector. At a high-level session on the cotton industry organized by the World Trade Organization in Geneva on March 15 and 16, 2007, UNIDO presented a document entitled "Support to the Cotton Sector and Prospects for Industrialization".
