Abstract:
A process for forming a continuous filament carpet yarn from at least two individual filament bundles wherein at least one physical characteristic of the filament bundles is different so as to produce a desired visual effect in the continuous filament yarn, said process comprising the steps of:spinning at least two separate filament bundles in a continuous on-line process wherein at least one physical characteristic of the filament bundles is different and selected to produce a desired visual effect in the continuous filament yarn formed from the filament bundles;cooling the spun filament bundles and conveying the cooled filament bundles to a texturizing stage;separately texturizing each of the filament bundles so as to prevent mixing of the filaments between filament bundles during said separate texturizing, said texturizing further comprising heating each of the filament bundles and compressing or crimping each of the filament bundles into a plug;cooling each of the separately texturized filament bundle plugs; andjointly compacting the separately texturized filament bundles after said cooling so as to merge the bundles into the continuous filament yarn with the desired visual effect.
