Texturing Nozzle with Counter Air Cooling for Crimp Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional texturing devices for crimped plastic filaments require significant energy consumption and installation space due to the use of a cooling drum with a vacuum chamber, which is inefficient and costly.
Innovation Solution
A texturing device with an integrated counter air flow mechanism in the texturing nozzle, comprising a filament guide slot tube and a counter air flow slot tube, eliminates the need for a cooling drum by using a counter air flow to crimp and cool the filaments within the nozzle, reducing energy consumption and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cooling drum with vacuum chamber is used to cool and fix crimped filaments, then the crimp is fixed effectively, but energy consumption and installation space increase significantly
Solution Approach 1:
The cooling mechanism is integrated directly into the texturing nozzle, merging the crimping and cooling functions into a single component. The counter air flow slots are incorporated into the nozzle structure, eliminating the need for a separate cooling drum and vacuum chamber system, thereby reducing energy consumption while maintaining crimp fixation effectiveness.
Solution Approach 2:
The patent extracts the cooling function from the separate cooling drum system and integrates it directly into the texturing nozzle through counter air flow slots. This extraction and reintegration eliminates the need for the vacuum chamber and associated high energy consumption while preserving the essential cooling and crimp fixation function.

The counter air flow slots are incorporated into the nozzle structure, eliminating the need for a separate cooling drum and vacuum chamber system, thereby reducing installation space while maintaining crimp fixation effectiveness.
3Productivity
If hot compressed air flow is used to crimp filaments in a texturing nozzle, then crimping is achieved, but the filaments need additional cooling mechanism
Solution Approach 1:
The cooling function is merged with the texturing nozzle by incorporating counter air flow slots directly into the nozzle structure. This integration allows the nozzle to perform both crimping (via hot compressed air) and cooling (via counter air flow) functions simultaneously, reducing device complexity while maintaining crimping efficiency.
Solution Approach 2:
The counter air flow acts as an intermediary cooling medium that flows through slots in the nozzle, providing a simple and effective cooling mechanism without requiring complex vacuum chambers or separate cooling drum systems. This intermediary approach simplifies the overall device structure while maintaining productivity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integrated counter air flow mechanism effectively crimps and cools the filaments, fixing the crimp without a cooling drum, resulting in a more economical and compact texturing process with reduced energy and space usage.
Implementation Method 1
In the nozzle insert of the texturing nozzle that is closed circumferentially except for the hot compressed air supply port, at least one plastic filament is heated so strongly by the hot air flow
Implementation Method 2
the at least one crimped plastic filament is cooled in that a counter air flow, which is at least partially directed counter to the hot compressed air flow and which is cooler than the hot compressed air flow, is directed onto the at least one crimped plastic filament

AI summary
A texturing device for producing crimped plastic filaments has a texturing nozzle with a hot compressed air supply port and a filament guide slot tube. A cooling mechanism in the form of a counter air flow mechanism is integrated in the texturing nozzle. A crimped plastic filament is formed by blowing a plastic filament through a nozzle insert in a conveying direction by hot compressed air and crimping in a filament guide slot tube. Then the crimped plastic filament is cooled by a counter air flow, which is cooler than the hot compressed air flow and which is directed onto the crimped plastic filament. A counter air flow slot tube is arranged between a cooling air supply port of the counter air flow mechanism and the filament guide slot tube. A pass-through nozzle is arranged between the counter air flow slot tube and the cooling air supply port.
