Linyi Silk Road International Trade Co., Ltd.

Heats and melts polypropylene (PP) or polyethylene (PE) plastic pellets, extrudes them through a mold into film, then cuts and stretches them into flat yarn (the core raw material for woven bags).

Advantages

Highly automated: Fully automated control throughout the process reduces manual intervention and minimizes operational errors.

Energy-efficient and high-performance: Utilizes an efficient heating and cooling system with low energy consumption and fast production speeds (up to 200 - 300 meters per minute).

Automatically winds the flat yarn produced by the spinning machine into neat yarn spools for use in subsequent circular weaving machines or webbing machines.

Advantages:

Intelligent Tension Control: Real-time sensing of tension changes to prevent yarn breakage or loose winding, ensuring uniform winding density.

Large Capacity Design: Single roll capacity up to 20 - 30 kilograms, reducing roll change frequency.

Weaves flat yarn into cylindrical fabrics (such as woven bag tubular fabric) through warp and weft interlacing to form a high-strength structure.

Advantages

Precise Weft Density Control: Servo motor-driven weft insertion with an error of ≤1 thread/10cm, ensuring consistent fabric density.

High-efficiency production: Multi-shuttle design (4 - 12 shuttles), weaving speed up to 120 - 200 revolutions per minute, daily output exceeding 10,000 meters.

Wide width adaptability: Can produce cylindrical fabrics with diameters of 30 - 120 cm, accommodating different specifications of jumbo bags.

Produces high-strength webbing (such as jumbo bag slings, strapping bands) using plain weave or jacquard technology.

Advantages:

Ultra-high speed operation: Spindle speed up to 800 - 1200 rpm, single machine daily output of 5000 - 8000 meters.

High-strength output: Multi-layer weaving technology achieves webbing tensile strength of 1 - 5 tons (depending on material and specifications).

Versatility: Supports multiple raw materials such as nylon, polyester, and PP, capable of producing complex textures like plain weave and twill.
