Entanglement Nozzle Array for Composite Thread Color Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for entangling individual threads in composite threads lack flexibility to produce a wide spectrum of colors and uniform physical properties, making it difficult to meet changing fashion trends and ensure high-quality carpet yarns.
Innovation Solution
The device refines the entanglement process by using a thread guide on a support to guide individual threads around the circumference of godets before crimping, allowing for optional entanglement at entanglement nozzles, with nozzles arranged in a reference circle for consistent deflection and separate air supply for independent control, ensuring gentle thread handling and reproducible color effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual threads are entangled in mutually separate entanglement nozzles to achieve different color effects, then color variety and flexibility are improved, but thread handling complexity and device complexity increase
Solution Approach 1:
The device divides the entanglement process into multiple independent entanglement nozzles (first, second, and third entanglement nozzles), each capable of independently entangling individual threads. This segmentation allows different color effects to be applied to different threads simultaneously, achieving color variety while maintaining manageable device complexity through modular design
Solution Approach 2:
Each entanglement nozzle is designed with universal functionality to handle individual threads independently while contributing to the composite thread formation. The nozzles can be selectively activated and controlled to achieve various color patterns, providing adaptability without requiring entirely separate systems for each function
2Reliability
If compressed air streams are supplied to entanglement nozzles to entangle individual threads, then entanglement effectiveness is improved, but thread damage and harsh treatment increase
Solution Approach 1:
The device supplies compressed air streams locally and selectively to specific entanglement nozzles based on the entanglement requirements of individual threads. This localized air supply allows gentle handling of threads that do not require entanglement while providing focused entanglement force only where needed, reducing overall thread damage
Solution Approach 2:
The system enables partial entanglement by activating only the necessary entanglement nozzles for specific threads within the composite thread. This partial action approach applies compressed air only to the extent required for achieving the desired color effects, avoiding excessive air exposure that could damage threads
3Adaptability or versatility
If multiple entanglement nozzles are arranged sequentially to entangle threads independently, then color flexibility is improved, but manufacturing complexity and production time increase
Solution Approach 1:
The device merges multiple entanglement nozzles into a single integrated apparatus where first, second, and third entanglement nozzles work simultaneously on different individual threads. This combining approach allows multiple color effects to be applied in parallel during a single pass, achieving color flexibility without proportionally increasing production time
Solution Approach 2:
The entanglement nozzles are pre-configured and positioned to receive individual threads in a predetermined sequence and arrangement. This preliminary arrangement allows threads to be efficiently directed to the appropriate nozzles without complex real-time decision-making, reducing processing time while maintaining color flexibility

AI summary
Various techniques involve a device for entangling a plurality of individual threads of a composite thread in a melt-spinning process for the production of crimped yarns. The device to this end has a plurality of entanglement nozzles which are collectively held on a support. In order to enable a flexible utilization of the entanglement nozzles and of thread guiding, the entanglement nozzles on the support are assigned at least one thread guide in such a manner that the threads are guidable optionally in the entanglement nozzles and/or in the thread guide.
