The present invention relates to twisted yarn (P) obtained by twisting a plurality of carbon fiber resins which are slit from a carbon fiber resin tape (F2), open yarn obtained by S-twisting and Z-twisting covering yarn (C) around the periphery of the twisted yarn (P), carbon fiber covered twisted yarn obtained by winding the twisted yarn around the periphery of a core material, and methods for manufacturing thereof.

A material sheet is formed of a woven fabric of polymer tapes, wherein the width of a tape varies less than 2% on average in the longitudinal direction of the tape. Processes for the preparation of the material sheet, and to a ballistic resistant article comprising the material sheet are also provided. A ballistic resistant article which includes the material sheet exhibits excellent antiballistic properties.

An electronic functional member includes a core wire assembly including at least two metal wires, an insulating layer covering the at least two metal wires so as to expose a portion of the at least two metal wires, and an electronic functional element electrically conductive to each of the at least two metal wires, and a sheath including a knitted fabric covering the core wire assembly.

An anisotropic tatami cover can provide different hues depending on the angle from which it is viewed, and is therefore highly aesthetically valuable. The anisotropic tatami cover is made of weft yarns made of rush grass or artificial rush grass and warp yarns, is woven in such a manner that the warp yarns are exposed on the surface, and has a color difference E of 6.0 or more between the weft and warp yarns.

Disclosed is a woven three-dimensional (3D) fiber reinforced structure and method of making thereof having improved shear stress and stiffness. The structure is fabricated from tows with off-axis fiber reinforcement. The tows can replace warp or weft tows used in standard 3D weaving processes.

A covered yarn material for a heating blanket felt, a covered yarn, and a woven product thereof are provided. The covered yarn material includes a skin-layer material and a core-layer material, where the skin-layer material includes 20 wt % to 30 wt % of a powder melt mixture and 80 wt % to 70 wt % of a mixed-melt raw material; the core-layer material includes 100 wt % of a core-layer filament; the powder melt mixture is composed of the following components: 20 wt % of a carbon nanotube (CNT), 35 wt % of a graphite powder, 25 wt % of a copper powder, and 20 wt % of a jade ore powder; the mixed-melt raw material includes one or more from the group consisting of polyethylene terephthalate (PET), polyamide (PA) 6, PA66, polyphenylene sulfide (PPS), liquid crystal polymer (LCP), and polycarbonate (PC); and the core-layer filament includes one or more from PET, PA66, PPS, and LCP.
