Abstract
The invention relates to a method and to a device for producing a crimped composite thread. The crimped composite thread includes a first polymer melt and a second polymer melt. The first polymer melt and the second polymer melt are arranged next to one another, in particular side-by-side, in portions in such a way that a composite thread is formed. The first polymer melt and the second polymer melt each have a different material property so that self-crimping of the composite thread is initiated by means of an active crimping initiation. Additionally, there is a system for producing a crimped composite thread from a bulk continuous filament yarn for carpet yarn using the method and the device.
