Filter Bag Processing Standards and Fine Stitching Techniques

At AGICO Group, our filter bag processing meets industry standards such as HJ/T326-2006 and GB/T 12625. We use CNC cutting machines to ensure stable and accurate dimensions during the cutting process. Our bag tube is sewn using a continuous production line to improve the overall quality of our product. Additionally, the bag mouth uses a stainless steel ring for added durability.

To ensure that our filter bags can be installed without gaps, we make sure that the upper and lower pieces of the bag body lines are flat, and the bag mouth and bag bottom joints are evenly folded. We use a three-needle stitching process for the bag body with high-quality, high-temperature-resistant, corrosion-resistant, and high-strength sewing thread. Even strong acids and alkalis have difficulty corroding or damaging it, ensuring that the bag will not tear due to spray blowing.

We take quality control seriously and follow strict guidelines in every step of our production process. Each process is managed according to the ISO9001:2015 quality management system standards. We have over 50 steps from raw material inspection and cleaning to finished product warehousing, with each step having key quality control points to strengthen our quality control during production. We have established a four-level inspection system of "employee self-inspection, workshop inspection, quality inspection, and random inspection" and adhere strictly to the principle of "no turning, no warehousing, and no factory shipment" for defective products. Our ultimate goal is "zero defects, zero complaints, and zero returns."

At AGICO Group, we are committed to providing the highest quality filter bags to our customers. Our fine processing techniques and strict quality control measures ensure that our products meet industry standards and exceed customer expectations.

Manufacturing process of high-speed needle punching machine for filter bag production

The manufacturing process of a high-speed needle punching machine for filter bag production involves several steps. First, Polyphenylene sulfide (PPS) and ultra-fine fiber are opened, carded, and laid out as a web. Then, a PPS fiber base cloth undergoes pretreatment to become a high-performance PPS fiber base cloth. Another batch of PPS and ultra-fine fiber is opened, carded, and laid out as a web.

Next, pre-needle punching is done, followed by four primary needle punchings, PTFE impregnation, and PTFE film covering. The surface layer of the resulting PPS + ultra-fine fiber coated needle punched felt filter bag is made of PPS fibers, which are needle punched with high-performance PPS base cloth. PPS fiber has good spinability, improving the composite fastness and overall strength of the filter material.

The base cloth of the filter bag is made of high-strength PPS long fibers, woven into a high-strength PPS base cloth to ensure that the filter material has sufficient mechanical strength. After undergoing pretreatment and heat setting, the high-performance PPS base cloth with excellent physical and chemical properties and stable dimensions is produced.

Needle punching

The needle punching process involves mixing two high-quality fibers with the high-strength base cloth using our company's mature needle punching technology and Germany's DILO automatic equipment. This creates a needle punched filter material with good flexibility and excellent cohesion, significantly improving the composite fastness and overall strength of the filter material.

After the PPS + ultra-fine fiber coated needle punched felt filter material is produced, our company uses a unique post-processing formula called "Polytetrafluoroethylene (PTFE) mixed solution" for this working condition. The product is treated with water and oil repellency and PTFE impregnation, and then subjected to high-temperature sintering treatment. This fully wraps the surface of each short fiber in PTFE emulsion, playing a protective role of nano-coating. This significantly improves the overall anti-oxidation, corrosion resistance, temperature resistance, and size stability of the filter material. The water repellency of the filter material is enhanced, the filtration accuracy is improved, and the service life of the filter material is extended.

The three-dimensional structure of the filter material is not only conducive to the rapid formation of a dust layer but also does not have a direct passage of pores after dust collection and cleaning. This ensures stable dust collection efficiency, and the dust removal rate is higher than that of general woven filter materials. The dynamic dust collection rate can reach over 99.9% - 99.99%.
