Summary: | In this work, polyamide 66/meta-aramid composite yarn was manufactured for applications involving extreme temperatures. Three types of spinning methods were chosen, including siro core-spun, sirofil and embedded and locatable spinning (ELS) systems. Under the discussion of the filament motion feature and the staple fiber trapping effect separately, it is concluded that the siro core-spun system has the lowest trapping ability for the staple fibers due to the loose interaction force between the filament and the rovings. By contrast, the twist effect between the filament and the rovings in sirofil method prevents the fiber migration, resulting in a more stable yarn. Finally, ELS system further enhances the wrapping effect of the fibers outside. For the specific properties, hairiness tests and SEM photos of the yarns prove that the ELS system has the best control of the surface fibers, contributing to better uniformity. Similarly, the tensile property for the ELS yarn is also better than the other two. Finally, the tensile modulus and thermal property of the the ELS composite yarn fabric almost remain the original level after the high and low temperature cycling tests, demonstrating promising application prospect in the extreme environment. |
