Provided herein are a controllable liquid transport material, a controllable liquid transport system and a method for preparing a controllable liquid transport material, where a first region of the controllable liquid transport material is treated to be hydrophobic, while a plurality of second regions partially contacted or completely separated with different shapes are treated to have a gradient or varied wettabilities and/or pore sizes for passively controllable liquid transport, and/or integrated with a smart material for actively controllable liquid transport driven by an external force, allowing efficiently and controllably directional transport of a liquid e.g., sweat. The controllable liquid transport system comprises a controllable liquid transport material used as a liquid transport layer and a breathable, waterproof protective layer.

A webbing for use with a tiedown or sling which has overall increase strength efficiency when compared to known tiedowns or slings which use texturized yarn. The webbing contains non-texturized yarn material having reduced elongation characteristics in the core, combined with non-texturized yarn having higher elongation and improved wear characteristics on the exterior surfaces.

A method for preparing a liquid crystal polymer film, comprising: (1) spinning a liquid crystal polymer into fibers, and maintaining the fibers for 0.1 hour to 36 hours at a temperature of 200° C. to 400° C. under a vacuum degree less than 500 Pa for later use; (2) weaving the fibers prepared in step (1) into cloth for later use; and (3) pressing the cloth prepared in step (2) into a film at a temperature of 200° C. to 400° C., and then stretching the film to obtain the liquid crystal polymer film. The liquid crystal polymer film prepared by the preparation method is good in mechanical property, and has a tensile strength that can exceed 170 MPa. The prepared liquid crystal polymer film is applied to a FPC, which makes the FPC have a dielectric constant less than 3, and a small dielectric loss tangent angle.
