ANTI-INCENDIARY FLEXIBLE INTERMEDIATE BULK CONTAINER SYSTEM

摘要

The present invention provides for an antistatic flexible fabric material (1 0) formed from woven, axially oriented crystalline polypropylene yarn (11, 12) having a coating of flexible thermoplastic polymer or blend (22) on one or both sides. The fabric may also contain a layer of cellulose material (24) laminated to the uncoated side. Antistatic properties are imparted to the fabric by including a polyol ester of a C10 to C28 fatty acid in the coating and optionally in the polypropylene yarn (11, 12). The present invention als o provides for a quasi-conductive woven fabric section including quasi- conductive fibers which reduce the potential for incendiary discharge. The woven fabric section (10) may further include an antistatic coating. The coating may be applied to an entire surface of the woven fabric section or i t may coat about one-half of the section.
