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.

Method for producing a crimped composite thread, wherein the crimped composite thread has a plurality of composite filaments from a first polymer melt and a second polymer melt, wherein the first and the second polymer melt are arranged next to one another, side-by-side, in portions in such a way that a composite thread is formed, wherein 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 open-loop and/or closed-loop controlled by an active crimping initiation at a predetermined point in the method, and wherein the composite thread is configured to be trilobal in shape.
Device for producing a crimped composite thread, which is specified for carrying out a method for producing the crimped composite thread, in which the crimped composite thread has a plurality of composite filaments from a first polymer melt and a second polymer melt, wherein the first and the second polymer melt are arranged next to one another, side-by-side, in portions in such a way that a composite thread is formed, wherein 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 open-loop and/or closed-loop controlled by an active crimping initiation at a predetermined point in the method, and wherein the device has an installation for the active initiation of self-crimping of the composite thread, and wherein the composite thread is configured to be trilobal in shape.
System for producing a crimped composite thread from a bulk continuous filament yarn for carpet yarn, which is specified for carrying out a method for producing the crimped composite thread, in which the crimped composite thread has a plurality of composite filaments from a first polymer melt and a second polymer melt, wherein the first and the second polymer melt are arranged next to one another, side-by-side, in portions in such a way that a composite thread is formed, wherein 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 open-loop and/or closed-loop controlled by an active crimping initiation at a predetermined point in the method, and wherein the composite thread is configured to be trilobal in shape.
