摘要： A filament comprising a polymer blend and specific articles comprising the filament are disclosed. The polymer blend includes an aliphatic nylon and a semiaromatic nylon. The aliphatic nylon is the major component of the blend and semiaromatic nylon is the minor component of the blend. The aliphatic nylon can be Nylon 6, Nylon 66, Nylon 610, Nylon 612, Nylon 12, and mixtures thereof. The semiaromatic nylon can be 6I/6T, 6T/6I, and mixtures thereof. The nylon blend filament provides enhanced mechanical properties such as modulus, ultimate strength, and yield strength with improved processability and reduced diameter variability at a reduced cost.

摘要： Enhanced suffusion coated and laminated nylon fibers are described. The fibers are formed from a blend of an aliphatic nylon and a semiaromatic nylon that is subsequently suffused with carbon. The nylon blend demonstrates advantageous physical properties over typical nylons, and the carbon suffusion process unexpectedly improved these physical properties further.
