ABSTRACT:
A method of manufacturing twistless yarn, in which a sliver or a roving consisting of a fibrous material containing at least two components, at least one being a potential adhesive, is wet-drafted, false twisted and then, after supplying additional moisture, bonded. After the application of additional moisture the fibrous sliver is passed through a narrow space and heated, such that only a small amount of moisture in the fibrous sliver evaporates and a rapid saturation of moisture in the space is obtained. The potentially adhesive component is thereby sufficiently activated by the residual moisture in the fibrous sliver.
