TH74458A - Polybenzazole fibers And products made up of this fiber - Google Patents

Abstract

DC60 (07/03/48) This invention relates to polybenzazole fibers, which can remain highly resistant to High temperature and high humidity atmospheres even when the threads made of these fibers have internal kink bands due to damage during the process of operation. Later processes for making woven fabrics, braids, braid pieces, ropes and invention chords also involved products that included polybenzol fibers, particularly spun yarn, rubber reinforcement materials, materials. Complementary elements Strong with fibers, woven or knit fabric, knife or bulletproof material, rope and sail cloth.

1.Polibenzazole fibers with strength (%) 80% or more are determined by the equation: (a / b) X 100 given the notation a and b. As follows: The notation a indicates the strength of the side line. [Centi Newton / decitex] measured as follows: Long fibers of polibenzazole have been Twist an S-shaped strand with a twisting coefficient of 30 for the formation of threads. Which is then left for 30 seconds and the yarn is unscrewed in the S shape until the gauge twist coefficient:
