ABSTRACT:
Process of producing a composite thread in which at least one multifilament thread is run freely and substantially perpendicularly onto a core thread being drawn through a false-twist interval, such that the multifilament thread forms a sheath of at least partially separated filaments wrapped around the core thread, at least one of the core and sheath threads being heat-fixed or heat-set while in a twisted state. The product of the invention is a composite thread exhibiting the properties of natural fibers, especially wool-like properties, with relatively large variations in texture and crimping characteristics. The apparatus of the invention includes, in addition to conventional false-twist means for the core thread, a delivery means to supply at least one additional multifilament thread in a free path substantially perpendicularly onto the core thread in its false-twist interval.
