Flexible intermediate bulk container with induction control

The patent applies composite materials by combining conventional polypropylene fabric with conductive or quasi-conductive fibers (such as carbon black-filled polypropylene or metalized fibers) woven into the fabric structure. This creates a multi-functional material that maintains the original fabric's manufacturing advantages while adding electrostatic charge dissipation capabilities through the conductive fiber network, thereby resolving the contradiction between ease of manufacture and electrostatic safety.

The patent applies local quality by incorporating conductive or quasi-conductive fibers at specific locations and densities within the fabric structure, such as in the warp or weft directions, or concentrated in areas prone to static buildup. This localized approach provides effective charge dissipation pathways where needed most, while minimizing the overall complexity and cost compared to making the entire fabric uniformly conductive.

The patent applies self-service by designing the FIBC with inherent charge dissipation capabilities through the conductive fiber network embedded in the fabric. The container serves itself by automatically dissipating electrostatic charges through the quasi-conductive fabric structure without requiring external grounding connections or additional equipment, thereby maintaining ease of operation while eliminating induced voltage hazards.

The patent applies composite materials by integrating conductive or quasi-conductive fibers directly into the fabric weave during the manufacturing process, rather than applying separate antistatic coatings. This approach combines the structural integrity of the polypropylene fabric with the electrostatic dissipation properties of the conductive fibers, achieving effective charge reduction while maintaining manufacturing simplicity and avoiding the complexities of coating application and curing processes.
