What are the basic knowledge of nylon filter bags?

Time: 2022-01-07

Nylon filter bags are sewn with high-strength nylon woven mesh, and all use unique hemming technology to prevent needle hole leakage to the greatest extent, and directly intercept impurities in the filter that are larger than its own mesh on the surface of the material; the diameter is smaller than the mesh The particles with the mesh number pass through the mesh and enter the downstream. Therefore, the nylon monofilament filter bag realizes surface filtration. The smooth surface is also easy to clean and can be used repeatedly.


Recommended Accuracy


It is recommended to use nylon filter bags of 80 mesh to 350 mesh in the food and beverage industry; nylon filter bags of 80 mesh to 150 mesh are recommended in the chemical industry.



1.) Bag mouth design: PP plastic ring, galvanized steel ring, stainless steel ring, polyester rope (plus picture)

2.) Advantages: resistant to strong alkalis, can withstand a temperature of 150 degrees to 170 degrees; and has good deformation resistance and abrasion resistance, and can be washed repeatedly.

3.) Disadvantages: not resistant to strong acid

4.) Process method: adopt the tightest sewing with double needle hemming to ensure that each filter bag can achieve the best filtering protection.


Advantages of Nylon Filter Bag:

1.) It is produced by a high-speed industrial sewing machine without silicone oil cooling, and a filter bag that will not cause silicone oil pollution problems.

2.) There is no high protrusion at the suture of the nylon filter bag mouth after the improvement, and the side leakage is not caused by the needle hole, which leads to the side leakage.

3.) All labels on the nylon filter bag that indicate product specifications and models are selected in a way that is easy to remove to prevent the label and ink from contaminating the filtrate when the filter bag is in use.

4.) The filter accuracy ranges from 0.5 microns to 300 microns, and the materials are divided into polyester, polypropylene and nylon filter bags.

5.) Argon arc welding technology for stainless steel and galvanized steel ring. The diameter error is only less than 0.5mm, and the horizontal error is less than 0.2mm. The filter bag made of this steel ring can be installed in the equipment to improve the degree of sealing and reduce the probability of side leakage.

Nylon Filter Bag Product Application:

It is suitable for filtering general industrial liquids such as electroplating E, D paint, ink, coating, food, chemical industry, grain oil and other chemical liquids; acid and alkali fiber have high mechanical strength and can be used repeatedly.
