Product Specification

1900–2300 mm Wide-Width Circular Loom Machine for PP Woven Fertilizer Sack Fabric

Circular Loom for Wide Fertilizer Sack Fabric

This Wide-Width Circular Loom Machine is designed to weave PP tape yarn into continuous tubular fabric for fertilizer sack manufacturing. Its 1900–2300 mm fold-diameter range allows manufacturers to produce wide tubular fabric according to the dimensions and conversion requirements of large-format fertilizer packaging.

The machine completes the weaving and winding stages. The tubular fabric must pass through downstream coating, printing, cutting and sewing processes before it becomes a finished fertilizer sack.

Requirements of PP Woven Fertilizer Sack Fabric

Fertilizer packaging fabric must match the target sack dimensions, filling weight and subsequent converting process. Selecting the loom only according to its maximum speed may result in fabric that does not fit the cutting or sewing plan.

The buyer should first define:

• Required tubular fabric fold diameter;
• PP tape-yarn specification;
• Fabric warp and weft density;
• Target fabric weight;
• Finished fertilizer sack dimensions;
• Printing and coating requirements;
• Cutting and sewing allowances.

The loom supports a 10–16 picks/inch weft-density range, allowing the weaving parameters to be adjusted for different PP woven fabric specifications.

How the 1900–2300 mm Width Is Used

The fold diameter refers to the width of the tubular woven fabric when it is laid flat. It must be matched with the finished fertilizer sack body and the planned cutting method.

A wider loom does not automatically mean that it is suitable for every fertilizer sack. Buyers producing smaller conventional sacks should confirm whether the 1900–2300 mm range matches their actual product dimensions.

PP Tape Yarn Control

The machine is intended for PP, PE and synthetic tape yarn. For fertilizer sack fabric production, consistent tape dimensions and tension help control the woven surface and tubular fabric size.

The manual provides the following reference yarn conditions:

• Linear density: ≥111 tex;
• Linear-density deviation: ≤±10%;
• Relative tensile breaking force: ≥0.32 N/tex;
• Elongation at break: 15%–30%;
• Maximum warp quantity: 2592 ends.

Automatic warp let-off supports continuous yarn feeding. Warp tension can be adjusted on both sides of the machine according to the fabric specification.

Application

This Circular Loom Machine is mainly used by fertilizer packaging material manufacturers to weave PP tape yarn into wide tubular fabric for granular fertilizer, compound fertilizer and other dry fertilizer sack applications. The woven fabric can be wound into rolls and transferred to coating, printing, cutting and sewing equipment. When moisture protection is required, the appropriate coating or liner must be added during downstream converting because the circular loom itself produces only the woven base fabric.

Technical Parameters

Production Configuration Checklist

Before ordering, the fertilizer sack manufacturer should provide:

1. Finished sack dimensions;
2. Required tubular fabric fold diameter;
3. Fertilizer filling weight per sack;
4. PP tape-yarn width and tex value;
5. Target warp and weft density;
6. Required fabric weight;
7. Coated or uncoated fabric requirement;
8. Printing and cutting method;
9. Planned production capacity;
10. Available installation space.

These details determine whether the 1900–2300 mm loom matches the actual fertilizer sack production plan.

FAQ

Does this machine produce finished fertilizer sacks?

No. It produces tubular PP woven fabric. Finished sacks require additional coating, printing, cutting and sewing equipment.

Can it produce moisture-resistant fertilizer sacks?

The loom only weaves the base fabric. Moisture protection depends on the coating, liner and closure added in subsequent processes.

Is 1900–2300 mm suitable for every fertilizer sack?

No. It is intended for wide tubular fabric. The fold diameter must be checked against the finished sack dimensions and cutting plan.

Is 87 m/h the guaranteed production speed?

No. It is the documented maximum output. Actual production depends on fold diameter, fabric density, tape-yarn condition and machine settings.
