Different Types of Yarn Clearers in Winding Machines
When working with winding machines, choosing the right yarn cleaner is necessary to maintain yarn quality and prevent faults in the final product. These faults, if not removed, can affect the quality and strength of the yarn, causing problems during weaving or knitting.
Yarn clearers work by identifying irregularities in yarn thickness or foreign materials and removing those sections automatically. There are mainly two types of yarn clearers: mechanical and electronic. Mechanical yarn clearers use physical means to catch faults, while electronic ones use sensors for more precise detection and removal.
Choosing the right type of yarn clearer helps maintain smooth winding operations and improves the overall yarn quality. This blog explains the different types of yarn cleaners used in winding machines so you can understand their functions and decide which cleaner suits your needs best.
Quick Look:
Yarn clearers detect and remove faults such as thick spots, thin places, neps, and contaminants to ensure high yarn quality.
Mechanical yarn clearers use physical blades to catch thick faults, offering a simple and cost-effective option suitable for basic winding tasks.
Electronic yarn clearers use sensors (capacitive, optical, tribo-electric) to detect a wider range of faults, including very fine ones and contamination, with greater precision.
Selecting a yarn clearer depends on yarn type, fault detection needs, winding speed, and ease of adjustment to balance quality and production efficiency.
Modern electronic clearers provide real-time quality monitoring and allow fine-tuning of fault sensitivity for improved process control.
Integrating an appropriate yarn clearing system with your winding machinery is vital for smooth production and reducing defects in downstream fabric manufacturing.
Why Yarn Clearers Are Essential in Winding
Yarn clearers are essential in winding because they help ensure yarn quality by removing faults that occur during spinning. Even the best spinning processes produce yarn with imperfections like thick spots, thin places, neps, or foreign particles.
If these faults are not removed, they can cause breaks and faults downstream in weaving, knitting, or fabric manufacturing.
Importance:
Damage Prevention: Removing these faults early prevents breaks and defects in downstream processes like weaving and knitting.
Better Quality: Fault-free yarn leads to better fabric quality and fewer production interruptions.
Reduced Waste: Clearers help reduce waste by cutting out faulty yarn sections automatically.
Improved Production: Using yarn clearers improves overall production efficiency and reduces machine downtime caused by yarn faults.
Fault Detection: Modern yarn clearers provide precise fault detection, allowing you to set clearing limits according to your quality needs.
Consistency: They ensure smooth winding operation by maintaining consistent yarn quality through continuous fault removal.
Cost Saving: Yarn clearers contribute to cost savings by lowering material waste and reducing the need for rework in fabric production.
Different Types Of Yarn Cleaners in Winding Machines
Different types of yarn cleaners are used in winding machines to detect and remove faults in yarn before further processing.
These cleaners mainly fall into two categories: mechanical yarn cleaners, which use physical means to catch thick faults. The other one is electronic yarn cleaners, which use advanced sensors to detect a wide range of yarn imperfections more precisely.
Understanding these types helps you choose the right cleaner for your winding needs.
Different Types:
Mechanical Yarn Clearers
Mechanical yarn clearers are devices used in winding machines to remove thick faults or slubs from the yarn by physical means. They work by passing the yarn through an adjustable slot or blade, which traps yarn imperfections that are larger than a set size.
Once a fault is detected, the machine cuts the yarn at that point, preventing the fault from continuing through to later production stages. Mechanical clearers mainly focus on thick places and knots, but are less effective at detecting thin places or contaminants.
Their design is simple, making them easy to maintain and reliable for basic fault removal in winding processes. However, they lack the precision and advanced detection capabilities of electronic yarn clearers.
Types:
Fixed Blade Type: This type uses a blade with a fixed slot through which the yarn passes. It traps thick faults that are larger than the slot size and cuts the yarn at the fault.
Swinging Blade Type: This type features a blade that swings or moves to catch faults in the yarn. It can adapt to varying yarn thickness and helps remove knots or slubs more effectively than fixed blades.
Other Types: Variations include serrated blades or blades with special slots designed for specific yarn types or fault sizes. These aim to improve the catching of faults with less yarn damage.
Functions:
Detect thick spots or slubs by physically trapping yarn faults larger than a preset size.
Use a slot or blade through which the yarn passes; faults that do not fit the slot are caught.
Trigger a cutting device to remove the faulty yarn section once a fault is detected.
Prevent faulty yarn sections from continuing through winding, reducing defects downstream.
Focus mainly on thick faults and knots; less effective in detecting thin places or contamination.
Operate without electrical sensors, relying on physical measurement of yarn thickness.
Help maintain consistent yarn quality by removing major faults during winding.
Advantages:
Simple design and easy to maintain
Reliable for removing thick faults like slubs and knots
Operates without needing electrical power or sensors
Low cost compared to electronic clearers
Suitable for basic winding tasks and older machines
Electronic Yarn Clearers
Electronic yarn clearers are advanced devices used in winding machines to detect and remove a wide variety of yarn faults with high precision. These clearers use sensors to continuously monitor the yarn for thick places, thin places, neps, and foreign materials.
Electronic yarn clearers allow fine adjustments to suit different yarn types and improve production quality by reducing yarn breakage and fabric defects. They also often support real-time quality monitoring.
Types:
Capacitive Type: This clearer measures the yarn's mass per unit length using electrical capacitance. When the yarn thickness changes beyond set limits, the system triggers a cut to remove the faulty section.
Optical Type: Uses a light beam and sensor to monitor the yarn’s thickness and detect colored or transparent foreign materials. Faults are identified by changes in light intensity and then removed.
Tribo-electric Type: Detects synthetic fibers and contaminants based on the electrical charge generated by the friction between fibers and the sensor. This type is useful for identifying materials that are hard to detect optically, like polypropylene.
Functions:
Detect thick places, thin places, neps, and foreign matter continuously during winding.
Use sensors like capacitive, optical, or triboelectric to measure yarn characteristics.
Analyze signals to identify faults beyond set thresholds.
Automatically cut the yarn where faults are detected.
Allow adjustment of sensitivity and fault length for different yarn types.
Support removal of various defects, including short and long faults.
Provide real-time yarn quality monitoring and data collection.
Help separate off-quality yarn bobbins based on fault detection.

Criteria for Selecting a Yarn Clearer for Winding Machines
When choosing a yarn clearer for winding machines, it is important to focus on how clearly and effectively the device can identify and remove yarn faults. The right clearer plays a vital role in improving yarn quality and preventing problems in later production stages like weaving or knitting.
Each clearer varies in how it measures yarn thickness, detects contaminants, and adapts to different yarn materials and counts. Selecting a clearer that fits your specific yarn characteristics, production speed, and required fault sensitivity ensures a balanced performance that enhances both quality and efficiency.
This choice directly impacts how well you can meet quality goals while maintaining steady production output.
Factors to consider:
Type of Yarn Faults: Identify the common faults in your yarn, such as thick places, thin places, neps, or contaminants. Choose a clearer that can accurately detect and remove these specific faults.
Yarn Material and Count: The clearer should be compatible with the yarn type (cotton, polyester, blended, etc.) and yarn count you produce. Settings like material number and yarn count help the clearer adjust its sensitivity accordingly.
Clearing Sensitivity and Limits: The ability to set fault size thresholds and reference lengths is important. This lets you balance between yarn quality and production speed by controlling how many faults are removed.
Winding Speed Compatibility: Ensure the clearer works effectively at your winding machine’s operating speed. Some clearers can automatically adjust settings as speed changes for consistent performance.
Fault Detection Channels: Modern clearers may detect various fault types separately, such as short thick places, long thin places, or contamination. More comprehensive detection improves yarn quality.
Contamination Detection: For yarns prone to foreign fibers or colored contaminants, choose optical or electronic clearers with contamination detection features.
Ease of Adjustment: A user-friendly interface for quickly setting and optimizing clearing parameters helps maintain quality without causing excessive waste.
Maintenance and Durability: Consider the clearer’s design for ease of maintenance and robustness for continuous operation with minimal downtime.
