Circular loom process to make rPET FIBC bags

Circular Looms

The circular weaving process is a cornerstone in FIBC fabric production, where high-speed circular looms are employed to weave flat, circular, or U-panel woven fabrics. These looms use the stretched tapes produced in the tape stretching line to weave fabric with exceptional dimensional stability, high tear resistance, and low elongation properties. The advanced loom technology is engineered for precision warp control, automatic weft compensation, and low-friction shuttle movement, ensuring uniform fabric density and minimal weaving defects. The servo-driven warp tension control system optimises fabric strength and enhances seam integrity, which is essential for heavy-duty industrial applications.

Equipped with automatic tape feeding, tension monitoring, and high-speed shuttle movement, these circular looms can operate at speeds exceeding 800 picks per minute, maximising productivity and operational efficiency. These looms ensure fabric consistency with electronically controlled warp breaks detection and automatic shut-off systems, reducing material wastage and downtime. The woven fabric can be further enhanced with lamination or additional coatings, depending on the application requirements. With their low energy consumption, high output rates, and precision engineering, these circular looms are at the forefront of sustainable and efficient FIBC manufacturing, delivering premium-quality fabric tailored for global bulk packaging demands.
