An overview of the Boeing methodology for evaluating the inherently flame-retardant and thermally stable polymers with their possible application is presented. INTRODUCTION AND HISTORICAL OVERVIEW The selection of ineeAor textile materials for commercial airplanes that are light in weight, possess the desirable in-service use characteristics, and incorporate all the aspects of fire safety provides a challenging opportunity to incorporate the latest technology into the mainstream of commercial production.

It is expected that the BAP process would be slightly more expensive because more processing steps are required. The technical literature states that the standard zirconium finish is less durable in combination with the shnnk-resistant treatment than is the low-smoke version, and recommends the FR 756 to enhance washing fastness (WNZ, 19941.

SU10IARY AND CONCLUSIONS T have tried to provide a comprehensive status overview of all the wool flame-retardant finishing technology used within the airline industry today, and the growing interest by the airline customer toward a washable product, which includes washable FR wool.
