Chemical fiber filter cloth plays a crucial role in industrial production. However, during use or cleaning, the phenomenon of thread snagging may occur occasionally, which affects its filtration efficiency and service life. When encountering this problem, it is particularly important to adopt the correct and appropriate handling approach.
First, make a calm assessment and handle the situation differently
When you find a hook, do not forcibly pull or break it in a panic. The first step is to stop the operation immediately and carefully assess the degree of threading.
Slight hooking: If only one or a few strands of wire are hooked out but do not break, forming smaller rings or loops, this usually falls within the repairable range.
Severe snagging: If a large area or multiple threads are snagged, or even cause damage to the fabric structure and holes, the repair will be more difficult and replacement may need to be considered.
Second, perform precise operations and attempt to repair
For slight snagging, the following methods can be tried for repair:
Gentle back-pushing method: Keep your hands clean and use a smooth plastic needle or a slender crochet hook to carefully and slowly push the hooked thread back along the original path to the back of the fabric. When operating, patience is required to avoid excessive force which may cause the silk thread to break or aggravate the damage.
Low-temperature ironing assistance: For certain types of synthetic fiber filter cloth, after successfully pushing the silk thread back, you can place a thin cloth on the back of the hook area and use the low-temperature gentle ironing of an electric iron. This move helps to slightly shape the disturbed fibers and reduces the possibility of them coming out again. Be sure to test the heat resistance of the fabric in an inconspicuous place first.
Iii. Response and Prevention of Severe Damage
If the threads are severely hooked or holes have already formed, self-repair is often difficult to restore its original filtration accuracy. At this point, it is recommended to contact a professional filter cloth supplier or maintenance institution to assess whether there is any repair value. For the filter cloth in key process links, replacing it with a new one is usually a more reliable choice.
To reduce the occurrence of snagging, prevention is the key
Pay attention to the working environment: Clean the installation area of the filter cloth to ensure there are no sharp metal burrs, welding slag or other hard objects.
Standardize the cleaning process: Use a low-pressure water gun for rinsing and avoid using a hard-bristled brush for forceful scrubbing. When cleaning, you can turn the inside and outside of it upside down to reduce friction on the front.
Proper storage: After cleaning, it should be hung in a cool and well-ventilated place to dry. Avoid folding and heavy pressure, and keep it separate from sharp objects.
Conclusion
The key to dealing with the snagging of chemical fiber filter cloth lies in promptness and proper methods. Only by calmly assessing the degree of damage, taking targeted measures and strengthening daily prevention can the service life of the filter cloth be effectively prolonged and the stable operation of production be ensured.
