Using 100% polypropylene granules by high temperature melt extrusion nozzle made of fiber, again by polypropylene fiber spinning combed sliver of polypropylene yarn, our company has a complete assembly line process, ensure the quality of raw material source, post-production yarn is directly related to the quality of the raw materials, oil content of the filter in the process of working liquid bubble elimination time, ratio of we, after many years of technical research, can do oil content of 0.2% or less, the contact liquid foam: 1 second after the foam height less than 3 mm, 4 seconds after defoaming completely.

Advanced tumbler air spinning process is adopted. After our technical improvement in the later stage, the volume and weight of single yarn mass is larger than that of most products on the market. This advantage is that in the process of filter core, it can save workers' time to replace yarn mass, save labor cost to a greater extent, and improve production efficiency.

1. Ultra-low oil content for cleaner filtration

Through multiple technical optimizations, the oil content in the yarn is controlled at ≤0.2%, significantly reducing contamination risk in liquid filtration applications. This improves filter cartridge stability and extends service life.

2. Exceptional Chemical Resistance and Durability

Polypropylene is inherently resistant to acids, alkalis, and organic chemical solvents. Anda PP filter yarn maintains these properties consistently, ensuring that filter cartridges perform reliably even in aggressive chemical environments. The yarn is non-toxic, odorless, and non-absorbent to water. For procurement professionals, this translates to fewer product failure complaints and broader application compatibility across diverse industries-from municipal water treatment to chemical processing and food and beverage production.

3. Optimized Depth Filtration Structure

The yarn's open structure, achieved through carefully controlled twist levels, creates a depth filtration matrix that traps particles throughout the entire thickness of the wound cartridge rather than just on the surface. This design provides significantly higher dirt-holding capacity compared to surface-type filter media. For your manufacturing operations, this means your filter cartridges can offer longer service intervals-a key selling point that differentiates your products in a competitive market.

4. Stable raw material consistency

Using 100% virgin polypropylene ensures consistent fiber strength and stable performance across different production batches, reducing defect rates in end products.

Anda PP yarn for filter is the preferred raw material for manufacturing string wound filter cartridges used across a wide spectrum of industries:

• Water Treatment – Pre-filtration and ultra-pure water systems, beverage industry water treatment, and RO system pre-filtration
• Food and Beverage Industry – Edible oil filtration, vegetable oil processing, syrup clarification, chocolate and other liquid food filtration
• Chemical Industry – Plating solution filtration, paint and coating filtration, mechanical oil and cutting oil filtration, heavy oil and fuel filtration, high-viscosity resin filtration
• Pharmaceutical Industry – Process liquid filtration and pharmaceutical intermediate clarification
• Electronics Manufacturing – High-purity water systems requiring fine particle removal

The yarn serves as the filtration medium in depth filtration cartridge for low-viscosity liquids with low to moderate impurity content, making it versatile across virtually any application requiring reliable particle removal from water or aqueous solutions.

Q1: What is the difference between Anda PP filter yarn and standard polypropylene yarn?

A: Anda PP filter yarn is engineered specifically for filtration applications using a proprietary rotor spinning process with full microcomputer control. This eliminates yarn joints, ensures uniform diameter, and creates an open structure optimized for depth filtration-characteristics that standard textile-grade PP yarn does not offer.

Q2: What specifications are available?

A: Anda produces a wide range of specifications to meet different filtration requirements. Please contact our sales team with your specific needs for detailed specification sheets and samples.

Q3: Is the product suitable for food-grade applications?

A: Yes. Anda PP filter yarn is non-toxic and odorless, with quality certified by provincial health authorities. It is widely used in potable water filtration and food processing applications.

Q4: What is the typical lead time for international orders?

A: Lead times vary based on order quantity and specifications. With an annual production capacity of 5,000 tons, Anda maintains sufficient production flexibility to accommodate both regular replenishment and urgent orders. Please contact us for specific delivery schedules.

Q5: Do you provide samples for testing?

A: Yes. Sample quantities are available for customer evaluation and testing before bulk order placement.
