Recognizing the right time to replace sizing machine spare parts plays a pivotal role in maintaining weaving performance. This article provides an in-depth look at the wear-and-tear signs of sizing machine spare parts to prevent yarn breakage that causes production waste.
The sizing process is one of the most important stages in the textile industry, directly determining the strength, adhesion, and load-bearing capacity of the yarn before it enters the loom. In this operating system, equipment and sizing machine spare parts regulate temperature, pressure, and the amount of chemicals penetrating the yarn. However, over time of continuous operation, mechanical wear and the impact of sizing chemicals will degrade the functionality of these components.
Yarn breakage during the sizing process not only causes machine downtime and reduced productivity but also affects the surface quality of the finished fabric. To control this risk effectively, technicians need to clearly understand the lifespan and physical condition of each type of sizing machine spare parts. The article below will analyze in detail the signs of damage, periodic maintenance schedules, and key components that need close inspection to protect your production line.
1. The Importance of Timely Replacement of Sizing Machine Spare Parts
Maintaining the sizing machine spare parts system in top condition is not just a simple maintenance issue but a business strategy for textile enterprises. When components operate precisely, yarn tension is stably controlled, helping to minimize visual defects on the fabric.
1.1. Influence of Mechanical Parts on Yarn Quality
Yarn after passing through the sizing machine needs to achieve standard gloss, stiffness, and film adhesion. If the squeeze rollers – an important type of sizing machine spare parts – are deformed or unevenly worn, the amount of size absorbed into the yarn will be inconsistent, leading to spots that are too brittle or too weak, causing yarn breakage.
The stability of the equipment helps the protective film cover evenly around the yarn core. This reduces friction when the yarn runs through ceramic eyes or reeds on the loom later. Therefore, timely replacement of these items helps protect the quality reputation of the weaving workshop’s products.
1.2. Minimizing Idle Downtime
Whenever yarn breaks due to component failure, the entire line must stop for splicing and cleaning. This causes significant loss of labor and electricity costs. Proactively replacing worn elements helps businesses transition from reactive repair to preventive maintenance.
1.3. Protecting Related Equipment in the Line
A damaged component, if not replaced in time, can lead to a chain reaction. For example, a jammed bearing will put pressure on the motor and drive system, leading to much higher repair costs than maintaining the original unit.
2. Signs That Your Equipment Needs Replacement
Observing and measuring daily operating parameters will help early detection of abnormalities. Below are specific signs that machine operators should not ignore regarding their sizing machine spare parts.
2.1. Surface Roughness of Guide Rollers and Squeeze Rollers
Guide rollers are frequently in direct contact with yarn at high speeds. When the surface shows small scratches or oxidation, it becomes a factor causing yarn fraying. If the yarn is scratched right in the size vat, the yarn structure will weaken significantly.
For rubber squeeze rollers, if hardening or cracking appears on the outer surface, this is a mandatory signal to replace these sizing machine spare parts. Reduced elasticity makes the squeezing force no longer accurate, causing uncontrolled changes in the size pick-up ratio.
2.2. Unusual Noise and Vibration from Bearings
The bearing system is the main load-bearing component in the machine’s rotational movement. If you hear a squealing sound or feel strong vibration at the roller shafts, it is a sign of internal failure. A stuck bearing can cause the roller to rotate unevenly, creating sudden tension that breaks multiple yarns.
2.3. Deviations in the Temperature Control System
Temperature sensors and probes in the drying chamber are also classified as components that require high precision. If the actual temperature does not match the set parameters, the yarn may be scorched (if too hot) or not fully dry (if too cool), both cases leading to yarn breakage when passing through the winding unit.
2.4. Discoloration of the Sizing Solution Due to Component Corrosion
Sometimes, signs of damage lie not in the part itself but in the product. If you see rust spots or strange colored streaks in the size vat, it is likely that the stainless steel surfaces or metal sizing machine spare parts are undergoing severe chemical corrosion.
3. List of Components for Regular Inspection
To manage inventory effectively, businesses need to classify their parts by priority level and wear frequency.
3.1. Sizing Reeds and Their Role in Yarn Shaping
The sizing reed helps separate yarns evenly before entering the size vat and after leaving the drying chamber. Bent or worn reed teeth will cause yarns to stick together (entanglement). This is a type of mechanical unit that should be cleaned daily and replaced immediately upon signs of deformation.
Additionally, reed density must be checked to suit the yarn count being produced. Inappropriate parts will create unnecessary friction, weakening the yarn before it can be protected by the size.
3.2. Seals, Gaskets, and Leakage Issues
In size vats containing hot chemicals, seals prevent solution leakage. Sizing chemicals are often corrosive or highly adhesive, easily damaging soft elements like gaskets and seals. Sizing leaks are not only wasteful but also contaminate the machine area, hardening adjacent moving parts.
Replacing small sizing machine spare parts like gaskets is often overlooked due to their low cost, but the consequences of leakage can damage the entire electrical system and sensors beneath the machine.
3.3. Chain Drives, Belts, and Synchronization
Synchronization between roller shafts is maintained by the drive system. Stretched belts or loose chains will cause jerky movements. In the textile industry, even a slight jerk is enough to break fine yarns with high counts. Therefore, belts are components with a fixed expiration date that must be strictly followed.
3.4. Selvedge Cutting Systems and Related Components
During the winding process, managing the yarn selvedge is extremely important. If the selvedge cutters are dull, they will create jagged yarn ends that easily catch on other materials and cause breakage. Maintaining the sharpness of the cutters is an indispensable part of maintenance.
4. Technical Analysis: Types of Squeeze Rollers in Sizing Systems
The squeeze roller is the heart of the sizing machine. They decide what percentage of size will remain on the yarn.
4.1. Rubber Squeeze Rollers and Hardness Indices
This type of unit usually has a steel core and a special rubber coating. The hardness (Shore A) of the rubber must be kept stable. If the roller is too soft, too much size is absorbed, making the yarn take longer to dry and become brittle. If too hard, the size does not penetrate deep into the yarn core, reducing strength.
When checking these sizing machine spare parts, a specialized hardness tester must be used. Any deviation of more than 5-10% from the original design is an indicator that the rubber coating needs to be reground or replaced.
4.2. Stainless Steel Squeeze Rollers and Surface Finish
Some modern sizing machines use ultra-smooth stainless steel squeeze rollers. These are less prone to chemical wear but easily damaged by hard objects falling into the size vat. Just one small dent on the roller will create repeating defects on thousands of meters of yarn.
5. Temperature and Sensor Component Issues
The drying system accounts for most of the machine’s power consumption. Components in the drying chamber are under extreme temperature pressure.
5.1. Finished Yarn Moisture Sensors
These are smart units that help adjust machine speed. If the sensor fails or reports incorrectly, the yarn may be wound while still damp (causing mold) or too dry (causing yarn breakage during weaving). Equipment calibration should be performed monthly.
5.2. Steam Traps and Regulating Valves
For machines using steam for drying, the steam trap is an important unit that helps remove condensed water. If the steam trap is stuck, the drying roller temperature will be uneven, causing localized drying—a potential cause of yarn breakage that is difficult to detect.
6. Maintenance Process to Avoid Yarn Breakage
A methodical maintenance process will extend the life of your equipment and reduce pressure on the technical team.
6.1. Periodic Cleaning After Each Work Shift
Excess sizing chemicals sticking to various parts will dry and form sharp hard scales. Cleaning with hot water or specialized cleaning solutions helps surfaces stay smooth, protecting the yarn from surface damage.
In particular, size vats need to be completely drained to avoid bacteria growth that changes chemical properties, directly affecting the durability of metal sizing machine spare parts.
6.2. Applying Specialized Lubricants for Textile Components
Not all lubricants are suitable for the high-temperature environment of a sizing machine. Using the correct lubricant helps reduce internal friction, preventing overheating and premature wear of metal details.
A note when greasing these parts is not to let grease get on the yarn or into the sizing solution, as grease will prevent the size from penetrating the yarn, creating weak points that lead to breakage.
6.3. Checking Shaft Parallelism Alignment
Misaligned shafts are an indirect cause of parts failing faster than normal. Monthly, technicians should use laser rulers to check the alignment of the rollers, ensuring yarn tension is spread evenly across the machine width.
6.4. Checking the Anti-Static System
In the dry environment of the drying chamber, static electricity easily builds up on the yarn and plastic components. If the ionizer is broken, the yarns will repel each other or be attracted to the machine frame, causing tangles and breakage. This type of technical component needs periodic voltage testing.
7. Influence of Sizing Chemicals on Component Lifespan
Sizing chemicals not only affect the yarn but are also silent enemies of machinery.
7.1. Sizing pH and Metal Corrosion
Many types of sizing agents are slightly acidic or alkaline. If components with appropriate materials are not selected (such as 316 stainless steel instead of 304), pitting corrosion will occur, weakening the structure.
7.2. Starch Adhesion on Bearings
Sizing steam carrying tiny starch particles can penetrate inside bearings if the seals of the sizing machine spare parts are leaking. When this starch dries, it acts as an abrasive, destroying the steel balls inside in a short time.
