Innovation Solution
A false-twist texturing machine design that includes a false-twisting device with a disc and belt units to twist multiple yarns simultaneously, and a cooler with side-by-side cooling spaces to maintain short distances between yarns, reducing path differences and ensuring consistent cooling, thereby enhancing production efficiency and yarn quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of yarns to be simultaneously subjected to false-twist texturing is increased to improve production efficiency, then productivity increases, but the difference in quality between yarns (homogeneity) deteriorates due to path differences and entanglement
Solution Approach 1:
Multiple cooling spaces are merged into a single common cooler body, with all cooling spaces sharing a unified intake duct and cooling wind supply system. This integration ensures that all yarns receive cooling wind from the same source through substantially equal paths, eliminating quality differences while maintaining high productivity
Solution Approach 2:
The cooler is segmented into multiple independent cooling spaces (first cooling space, second cooling space, etc.), each capable of handling multiple yarns. This segmentation allows increased production capacity while maintaining uniform cooling conditions through the shared intake duct design
2Adaptability or versatility
If thicker yarns are subjected to false-twist texturing to meet market demands, then adaptability improves, but the complexity of maintaining homogeneity and production efficiency increases
Solution Approach 1:
The common intake duct and cooling wind supply system serve multiple cooling spaces simultaneously, creating a universal cooling mechanism that handles various yarn types and thicknesses uniformly. This multi-functional design simplifies the system while maintaining adaptability to different yarn specifications

Function Achieved in This Case
The machine effectively suppresses production efficiency loss and homogeneity issues, achieving good yarn quality by ensuring consistent twisting and cooling of multiple yarns in a small space, reducing path differences and entanglement, and facilitating easy threading.
Implementation Method 1
a cooler which is provided upstream of the false-twisting device in a yarn running direction in which the yarns run and is configured to cool the yarns
Implementation Method 2
an intake duct which has an intake space connected to the first cooling space and the second cooling space and is provided to supply cooling wind to the first cooling space and the second cooling space
Implementation Method 3
The running yarns having been twisted by the false-twisting devices are heated by the heater so as to be thermally set
