Abstract
A bi-regional fiber with a cellulosic core and a wax outer sheath is disclosed. The sheath can comprise high melting temperature wax. The fiber may be produced by processing the natural fiber at temperatures less than 70° C. The fiber can be processed in a standard manner, e.g., Keir process which may include bleach at approximately 100° C.. and the wax subsequently added at a temperature sufficient to disperse the wax over the fibers. The fibers are ignition resistant as measured by industry standard tests, e.g., FAR 25.853(b) or 14 CFR 25.853(b). The wax may comprise less than 1 percent to 25 percent of the fiber by weight. The wax may be natural wax, synthetic or emulsified wax or blends thereof. The bi-regional fibers can be blended with other fibers including BRCF fibers subject of U.S. Pat. No. 5,700,573.
