Design and Properties of Blended Sandwich Non-Drip Pa6 /Lenzing FR®/PBI Fiber Nonwoven Fabrics


In the current thermal protective clothing systems, maximizing the personal protection performance against fire and heat is in great demand. Additionally, minimizing the manufacturing cost by using low-cost materials is also a critical factor. In the previous study, a new type of low-cost flame resistant (FR) non-drip Polyamide 6 (PA6) fiber was developed. In this paper, this FR non-drip PA6 fiber was tested in blends with two inherently FR fibers to form FR nonwoven fabrics. Different formulations of varying blending ratios of these three fibers were processed into nonwoven fabrics. The vertical flame resistance and the thermal properties were characterized. Tensile tests were conducted to characterize mechanical properties of these FR nonwoven fabrics. The water vapor permeability test was also performed to measure the wearability of the fabric. Results of several polymer blends were compared to find the optimum formulation which will be used as low-cost thermal protective fabric in the future.
