    Dust removal is not an easy operation, since the dust particles are completely enclosed within the flocks and hence are held back during suction. It is mainly the suction units that remove dust (in this example 64%), dust removal will be more intensive the smaller the tufts. It follows that dust elimination takes place at all stages of the spinning process as shown in figure. Fig. 5 Dust removal as a percentage of
