Some factors affecting the tensile breaking strength of aramid yarns
The compressive strength of aramid yarn is high, which means that it has a very good tensile strength and is therefore commonly used in fire safety, electrical engineering construction, railway lines, petrochemical equipment and other industries. As a fiber ductile yarn, the performance of aramid yarn can take into account the requirements of various natural environments, especially in the field of cable wire to give full play to the significant advantages. Aramid thread is commonly used because of its good tensile strength, so what are the elements that endanger the breaking strength of aramid yarn Lashin, we simply grasp the next.
Aramid yarn Rashen fracture strength of the factors affecting
① fiber length: fiber length, generally longer and shorter than 2Lc (dislocation length) of the fiber composition, the aramid line compressive strength has quite a big injury. Such as aramid thread fibers in the short pile rate average increase of 1%, aramid thread compressive strength reduced by 1% to 1.2%.
② fiber compressive strength: the higher the relative compressive strength of fibers, the higher the compressive strength of aramid thread. In addition, the various factors that hurt the compressive strength of the fiber, as will be specifically expressed in the aramid web, but because and cotton aramid thread manufacturing, and not all consistent.
③ fiber particle size distribution: fiber is finer, softer, in the yarn between each other hold more closely, dislocation length may be reduced, yarn cross-section in the fiber yarn branch can be more, so that the fiber in the surface of the yarn transfer opportunities to improve, each fiber support more uniform, and thus the compressive strength of the yarn is higher.
The above are some of the factors that affect the breaking strength of aramid yarn, mastering this element is for the aramid line manufacturer to improve its tensile strength according to the production process is to assist, then the aramid line will appear more quality Lashin performance, firmly believe that the use of the period will also get fast play to improve, and its application of indoor space may also be more common. The production and application of some goods is actually made of aramid thread, if you look carefully at the words can be found.
