METHOD FOR PREPARING LIQUID CRYSTAL POLYMER FILM, LIQUID CRYSTAL POLYMER FILM AND APPLICATION THEREOF
20220403244 · 2022-12-22 ·

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.

A KIND OF MULTI-LAYER ARTIFICIAL LEATHER AND A PREPARATION METHOD THEREFOR, AN AUTOMOTIVE SEAT AND AN AUTOMOBILE
20220403589 · 2022-12-22 ·

An artificial leather includes a resin layer as the surface and a base fabric connected to the resin layer as the substrate. The base fabric comprises at least two monolayer structures arranged in an orderly manner as two laminates. Each monolayer structure is woven with some of the warp yarns and/or weft yarns in such layer or with some of the warp yarns and/or weft yarns in one or more other layers to form a number of connecting points, such that at least two monolayer structures arranged in an orderly manner as two laminates are connected with each other in the weaving process, forming a multi-layer integrated base fabric. The artificial leather incorporates a number of air vent holes distributed in the resin layer and the base fabric in the direction of thickness while retaining mechanical properties of tensile strength and tear resistance.

Wool Fabric With Stretch Properties and Garments Made Therefrom

Wool fabrics are disclosed that have improved stretch properties. The wool fabrics can be used in numerous and diverse applications, such as to make uniforms. The fabric can be designed to have greater than 15%, such as greater than about 20% stretch in one or more directions, such as in the fill direction. In one aspect, longer wool fibers are used in the fabric in order to increase durability.
