A reinforced substrate is provided for use in molding a composite material. The reinforced substrate has a reinforcing layer having reinforcing fibers extending in a fiber direction that is aligned in a single direction and auxiliary fibers laminated on only one surface of the reinforcing layer so as to extend in only one direction that intersects with the fiber direction. The auxiliary fibers are joined to the reinforcing fibers to hold the reinforcing layer. The auxiliary fibers have a higher tensile elongation at break than do the reinforcing fibers. The reinforcing layer is arranged with fiber bundles of large tows being aligned in an unopened state. The large tows have a higher fiber count of the reinforcing fibers than does a regular tow.

The present invention relates to a method for manufacturing precursor yarn comprising lignin, which may be further processed into intermediate carbon fibers and finally also carbon fibers. It also relates to carbon fibers and uses of said fibers. Said method involves applying a water-free spin finish.

A spinning-drawing-winding device for industrial polylactic-acid fiber includes a double-surface oiling mechanism, a filament shearing-suctioning device, a pre-interlacer and a splitting filament roller disposed in sequence according to a production process; a drawing-winding device cooperates with a spinning device, a tow passing from the spinning device through the double-surface oiling mechanism, the filament shearing-suctioning device, and the pre-interlacer in sequence until the tow is conveyed to the splitting filament roller; the drawing-winding device and the spinning device are configured as a parallel configuration, so that the tow between the spinning device and the splitting filament roller are arranged in a vertical direction and is tangential to the splitting filament roller, and therefore the tow is without deflection, thereby avoiding damaging the tow due to a friction caused by a higher deflection.

Embodiments of the invention include an active fiber with a piezoelectric layer that has a crystallization temperature that is greater than a melt or draw temperature of the fiber and methods of forming such active fibers. According to an embodiment, a first electrode is formed over an outer surface of a fiber. Embodiments may then include depositing a first amorphous piezoelectric layer over the first electrode. Thereafter, the first amorphous piezoelectric layer may be crystallized with a pulsed laser annealing process to form a first crystallized piezoelectric layer. In an embodiment, the pulsed laser annealing process may include exposing the first amorphous piezoelectric layer to radiation from an excimer laser with an energy density between approximately 10 and 100 mJ/cm2 and pulse width between approximately 10 and 50 nanoseconds. Embodiments may also include forming a second electrode over an outer surface of the crystallized piezoelectric layer.

The present disclosure relates to a non-woven fabric made from a fiber coated with a binder polymer by spinning a non-woven forming fiber in an organic binder polymer compound solution, an electrochemical cell using the non-woven fabric as a separator substrate, and a method of making the non-woven fabric, and the non-woven fabric has a pore diameter in a range of 0.001 to 10 ?m, thereby providing a mechanical property required for a separator while ensuring a favorable movement of a lithium ion, and in the use of the non-woven fabric as a separator of an electrochemical cell, eliminating a need for a process of applying a separate adhesive layer, resulting in an effect of simplifying a separator manufacturing process.
