How Much Net Can A Raschel Warp Knitting Machine Produce Per Day?

When buyers plan to invest in a Raschel warp knitting machine, it is important to understand the production capacity of each machine so that the capacity of upstream equipment can be properly planned, such as the output of extrusion lines for producing raw material yarn. This information also helps determine the required equipment investment, as well as the appropriate factory floor area, building height, and overall plant layout. So the first question they usually ask is:

How many kilograms or tons of net can one Raschel machine produce in 24 hours?

In general, a Raschel warp knitting machine typically produces about 500-1,000 kg of net per 24 hours under stable operating conditions. There is no single fixed answer. The daily output of a Raschel warp knitting machine depends on several factors, including machine working width, machine speed, net weight, mesh structure, yarn specification, machine efficiency, and the type of net being produced.

How to Calculate Daily Net Production?

Daily output can be estimated with the following formula:

Daily output (kg) = Working width (m) × Fabric speed (m/min) × Net weight (g/m²) × 60 × Operating hours × Efficiency ÷ 1,000

“Fabric speed” means the actual net take-up speed. It is not the same as the machine’s rpm because different mesh patterns require different numbers of knitting courses.

Production Example Using Chenye Machine Data

Take the Chenye HSRO-220 single needle bar Raschel machine as an example.

According to the HSRO Raschel knitting machine specifications, this model has:

· Working width: 260 inches, or approximately 6.6 meters

· Machine speed: 450–550 rpm

· Suitable net weight range: approximately 20–250 g/m²

· Applications: shade net, safety net, greenhouse net, breeding net and agricultural net

Suppose the machine produces a 100 g/m² shade net at an actual take-up speed of 1.5 meters per minute with 85% operating efficiency.

This example is for production planning only. The final output must be confirmed through a test using the buyer’s yarn and net specifications.

Does Higher RPM Always Mean More Output?

Not necessarily. A high machine speed can increase production, but RPM alone does not determine how many kilograms of net can be produced. machine must run in a very stable state; no yarn breaks; this is the most important.

For example, the Chenye RS-1 Raschel knitting machine is available in working widths from 130 to 260 inches. Depending on the width, its listed speed reaches 800–1,000 rpm. However, it can only produce a lightweight mosquito net/bale net. GSM is not so high, so output is also not so high. But the Chenye SROP knotless fishing net machine, through speed is only 300rpm, but 180inch machine can produce 1000KG/24h.  

What Factors Affect Daily Output?

The main factors include:

1. Machine Working Width

A wider machine produces more square meters of net during each operating hour, provided that other conditions remain similar.

2. Net Weight

Net weight is normally measured in grams per square meter. Heavier net produces more kilograms from the same area, but it may require more yarn and a lower production speed.

3. Mesh Size and Structure

Large, simple mesh structures are generally faster to produce than small, dense, or complicated patterns.

4. Yarn Material

HDPE flat yarn, PP yarn, monofilament, multifilament, and other materials require different yarn tensions and machine settings.

5. Operating Efficiency

Yarn changes, machine cleaning, maintenance, pattern adjustments, and unexpected stops reduce effective production time. For factory planning, using an efficiency rate of 80–90% is usually more realistic than assuming uninterrupted production.

How to Get an Accurate Output Estimate?

Before selecting a Raschel warp knitting machine, provide the manufacturer with:

· Net application

· Net width and mesh size

· Net weight in g/m²

· Yarn material and yarn specification

· Required daily output

· Planned operating hours

Chenye can use this information to recommend a suitable machine width and configuration. If possible, sending a finished net sample or detailed product photos will make the production estimate more accurate.

Conclusion

For many common agricultural, construction, and packaging nets, a practical planning estimate is approximately 500–1000KG per machine per 24 hours. Nevertheless, the correct figure depends on the exact net and operating conditions.
