Industrial PP Filter Yarn

Industrial PP filter yarn is produced using high-purity polypropylene chips that are melt-extruded into fibers and further processed through combing and spinning into uniform yarn. ANDA operates a fully integrated production line, ensuring strict control from raw material selection to final yarn stability.

Unlike standard textile yarn, this filtration-grade material is optimized for controlled density winding and consistent pore formation in filter cartridges. The result is a more stable filtration medium that supports high-efficiency liquid purification systems.

1. Ultra-low oil content for cleaner filtration

Through long-term technical optimization, the yarn achieves an oil content of ≤0.2%, significantly improving working fluid performance during filtration.
In practical testing conditions:

• Foam height is reduced to below 3 mm within 1 second
• Complete defoaming is achieved within 4 seconds

This directly reduces foam interference in filtration systems and improves liquid clarity and processing stability.

2. High-efficiency air spinning process

ANDA adopts an advanced tumbler air spinning process, improved through continuous engineering optimization. Compared with standard market products, each yarn bundle has:

• Higher bulk density
• Greater single-roll weight
• Improved structural stability

Buyer benefit: fewer yarn replacements during filter core production, reducing labor intensity and improving manufacturing throughput.

3. Stable polypropylene fiber structure

The yarn is made from 100% polypropylene granules, ensuring excellent chemical resistance and structural stability. A small amount of fluorescent agent is added during processing to improve visual consistency and whiteness, which also helps quality inspection during production.

Key technical stability benefits:

• Uniform fiber diameter
• Strong twist retention
• Consistent winding behavior

4. Improved production efficiency for manufacturers

Due to its higher single yarn mass and stable winding characteristics, this material helps filter cartridge producers:

• Reduce downtime during yarn change
• Improve winding speed consistency
• Lower overall labor cost per production batch

• • Material: 100% polypropylene (PP) chips
  • Color: natural white
  • Fiber length: 76–78 mm
  • Fiber fineness: 5–6 denier
  • Yarn size: approx. 1.8 mm
  • Twist level: 190–220 twists/m
  • Twist direction: Z (clockwise)
  • Oil content: ≤0.5% (optimized to ≤0.2%)

  Air spinning weight options:

  0.5 g/m, 0.6 g/m, 0.8 g/m, 0.9 g/m, 1.0 g/m, 1.2 g/m

  Foam performance:

  • Foam height < 3 mm after 10 seconds
  • Foam height < 1 mm after 40 seconds
