Yes. We have obtained the Food Contact Certificate and completed LUCID registration under German law, ensuring compliant global delivery without trade barriers.

What is the expected service life of Yiheng mesh belts?

Under standard operating conditions, Yiheng mesh belts typically last 3-6 months, significantly outperforming standard polyester mesh thanks to our high-wear-resistant materials.

What does DCD represent in the meltblown process, and what is its purpose?

DCD is the physical distance between the die head and the mesh belt. Adjusting it balances "filtration efficiency" and "softness," making it a key process variable in meltblown pro…

What is anti-static mesh? What are the thin black lines inside?

The thin black lines are specialized carbon fiber conductive yarns. They actively dissipate charges generated by friction, solving fabric sticking and flipping in dry environments.

What does CFM mean in belt specifications, and how does it affect production?

CFM is the unit of air permeability. It directly determines fiber adhesion and web uniformity, making it the primary technical parameter for selection.

Producing dark or high-end packaging non-wovens, clients complain about heavy mesh marks. Any upgrade solution?

Upgrading to "Flat Yarn weaving" is the best path. The flat surface provides more than twice the contact area of round yarn.

When producing soft hygiene fabric below 1.2 Denier, fiber hanging and streaks keep occurring. Which belt should I choose?

The key is "High-density weaving" and "Low CFM control." We suggest using the HY4106 Encrypted series.

My line speed exceeds 500m/min. Which belt should I purchase to ensure no speed reduction and no seam marks?

High-speed operation requires a solution with excellent anti-static performance and seam flatness. We recommend the SK604 High-Speed series with a High-Low Loop seam.

Why do High-Low Loop seams run more smoothly than standard Spiral seams?

Because it achieves a "zero-step" design. Special weaving allows seam loops to interlock without increasing total thickness, eliminating the source of vibration.

Why do minor deviations in air permeability (CFM) cause "cloudy spots" on the fabric?

Because CFM determines the distribution of negative suction pressure during web formation. Uneven distribution disrupts fiber flow, creating spots of inconsistent weight.

Why does adding black filaments into the polyester mesh prevent fabric flipping?

The black filaments are conductive yarns doped with carbon fiber; they actively dissipate frictional charges to the equipment's grounding terminal, eliminating static attraction.

Downtime for replacement is too long. Is there a way to shorten the tracking adjustment time?

Use the "Reference Marking Method." By marking a physical baseline on the tension rods, the new belt can be reset rapidly.

Threading the seam is difficult and keeps getting stuck. Any efficient techniques?

The key lies in "Tip Grinding" and using "Memory Steel." Keeping loop alignment and a smooth wire tip is essential for success.

Without an automatic corrector, how do I balance the tension on both sides?

Follow the "Marking Method" and "Reverse Tightening" principle. Symmetrically adjust bolts and observe during an empty run to lock the balance point.

How to clean polymer drips or lumps from the mesh without damaging it?

Use the "Heat Softening + Vacuuming" method. Never focus on one spot; move the heat gun constantly to prevent mesh thermal shrinkage.

The fabric starts to float or flip at speeds above 400m/min, severely affecting quality. What should I do?

Flipping is mostly caused by static attraction or unbalanced air pressure. Solve it by strengthening grounding and balancing cooling air vs. lower suction.

There are longitudinal streaks on the fabric, suspected to be fiber hanging. How to solve this?

The root cause is fiber penetration into the mesh. Solve it quickly by reducing lower suction and sanding foreign objects; adjust mesh CFM selection for a long-term fix.
