Nonwoven mesh belt selection starts with the belt's position in the production line, not its dimensions alone. Match the belt to the fibers it supports, the airflow or drainage required, operating temperature, tension and seam design. Two belts of the same size are not necessarily interchangeable, even when they serve the same type of nonwoven process.

For a purchasing or production team, a useful specification explains what the belt must do and under which conditions. This guide compares the main application questions and outlines the information to prepare before requesting a replacement or a new belt.

Identify the belt's function before comparing products

A nonwoven line can include web formation, conveying, bonding and drying. The belt does not necessarily experience the same conditions at every stage.

For a spunlace line, specify whether the belt supports the web during hydroentanglement, assists dewatering or conveys material elsewhere. For a needle-punching line, identify the conveyor's location and its relationship to the needle zone. Do not assume that an ordinary conveyor belt is designed for needles to penetrate it.

The YIHENG product range includes separate spunbond, meltblown and spunlace mesh belt categories. These categories provide a starting point, but the final specification still needs to match the machine and the installation position.

Compare nonwoven mesh belt requirements by process

This comparison is a specification checklist, not an interchangeability chart. Use the technical documentation for the proposed belt and machine to confirm allowable operating conditions.

Does a product change require a different belt?

A change in fiber fineness or finished-fabric basis weight calls for a suitability review, not an automatic belt replacement.

Fine fibers require appropriate support, but a tighter surface must still allow the airflow needed by the process. A change intended to reduce fiber loss should therefore be evaluated alongside suction resistance, cleaning and web formation. Similarly, a different fabric basis weight may change operating requirements without requiring a heavier belt.

Record the original and revised process conditions. Where the equipment permits a controlled trial, compare the results without changing unrelated settings at the same time. This makes it easier to distinguish belt performance from machine or process effects.

Prepare a practical belt specification

Before comparing offers, assemble the following information:

• Machine and position: equipment model, process type and the belt's exact function.

• Product: fiber material and fineness, fabric basis weight and surface requirements.

• Operation: line speed, tension, actual belt temperature and suction or drainage conditions.

• Dimensions and seam: width, length or circumference, seam type and installation orientation.

• Maintenance: cleaning method, cleaning media and any operating restrictions.

• Current problem: fiber loss, clogging, belt marks, mistracking or changes after cleaning, supported by photographs and records.

An existing belt code is helpful, but do not reuse it without review if the product or operating conditions have changed.

Frequently asked questions

Can one mesh belt be used for both spunbond and meltblown production?

Possibly, but only after checking the specific belt and operating conditions. Dimensions and appearance alone do not establish equivalent fiber support, airflow or surface performance.

Is drainage the only consideration for a spunlace belt?

No. Review the support position, structural stability, surface requirements, seam and interaction with the finished fabric as well as drainage.

Should a needle-punching line use a needle-resistant conveyor belt?

First establish where the belt runs. A belt used somewhere on a needle-punching line is not automatically intended for direct needle penetration.

Is a higher-temperature belt always a better choice?

Temperature capability is only one requirement. The belt must also meet the application's support, airflow, dimensional, strength and maintenance needs.

What information matters most before a new-product trial?

Document the differences from the current product and process, especially fiber characteristics, basis weight, speed, temperature and suction. Include the current belt's operating history.

Discuss the application, not just the belt size

A suitable belt balances web support, air or water flow and running stability for its intended position. No single parameter establishes that balance.
