Whirl-Tangling Crimped Compound Thread Manufacturing

The patent combines the crimping operations for multiple individual threads into a single common crimping chamber. Individual threads are introduced together into the crimping chamber with the aid of an advancing nozzle, where they undergo common crimping simultaneously. This merging of crimping operations reduces equipment complexity and process complexity while maintaining color separation effects achieved through prior separate whirl-tangling of each thread.

The patent applies whirl-tangling to individual threads before crimping, which creates controlled filament interlacing and thread cohesion through mechanical action rather than false twist. The whirl-tangling process parameters (such as tangling intensity and duration) can be adjusted to achieve optimal cohesion without causing excessive dominance of individual threads or hindering the subsequent crimping effect. This parameter adjustment allows balanced control of both cohesion and color uniformity.

The patent applies whirl-tangling with compressed air to individual threads in a controlled manner, using just sufficient pressure to achieve the required filament cohesion for stable thread formation. The compressed air pressure is optimized to provide partial action - enough to create adequate interlacing and cohesion, but not excessive pressure that would waste energy. This balanced approach achieves functional cohesion with minimal energy consumption.
