ABSTRACT:
In a method for the manufacture of twistless or substantially twistless yarn a sliver or a roving of staple fibres is used as basic material. The sliver or the roving is wetted by a liquid mixture containing a latent solvent for at least a portion of the staple fibre material and drafted in a wet condition to form a thinner fibre strand, which is subsequently false twisted and bonded. The fibre strand is bonded by activation of the latent solvent under an increased temperature, and dried under evaporation of the solvent.
