Abstract
A fabric for a thermal protective application includes: 5-40 weight % PBI-p fiber and the balance being conventional fibers, where the fabric has equal or better flame-resistant and/or heat-resistant properties, and a fabric weight less than an equivalent fabric made with a like amount of PBI-s fiber in place of the PBI-p fibers. The fabric for a thermal protective application includes: 5-40 weight % of a blend of PBI-p fiber and PBI-s fiber, and the balance being conventional fibers, where the fabric has equal or better flame-resistant and/or heat-resistant properties and a fabric weight less than an equivalent fabric made with a like amount of PBI-s fiber in place of the PBI-p fibers.

A fabric for a thermal protective application comprises:
- 5-40 weight % PBI-p fiber with a denier per filament in the range of 1.0-2.0 and the balance being conventional fibers, the PBI-p fiber having an APU in the range of 4-30%, and APU is phosphoric acid pick up,
- where the fabric has equal or better flame-resistant and/or heat-resistant properties, a fabric weight less than an equivalent fabric made with a like amount of PBI-s fiber in place of the PBI-p fibers, and a Dynamic Flame property of at least 28% greater than the equivalent fabric.
A fabric for a thermal protective application comprises:
- 5-40 weight % of a blend of PBI-p fiber with a denier per filament in the range of 1.0-2.0 and PBI-s fiber, and the balance being conventional fibers, the PBI-p fiber having an APU in the range of 4-30%, and APU is phosphoric acid pick up, the amount of PBI-s fiber being greater than the amount of PBI-p fiber,
- where the fabric has equal or better flame-resistant and/or heat-resistant properties, a fabric weight less than an equivalent fabric made with a like amount of PBI-s fiber in place of the PBI-p fibers, and a Dynamic Flame property of at least 28% greater than the equivalent fabric.
