    • The present invention relates to an eco-friendly composite long-fibrous non-woven fabric containing a plant-derived composition to improve productivity and a method for preparing the same. According to the method for preparing the eco-friendly composite long-fibrous non-woven fabric containing a plant-derived composition to improve productivity of the present invention, a filament constituting the non-woven fabric is formed in a sheath-core type, and polypropylene is positioned for a core component and plant-derived polyethylene is positioned for a sheath component, thereby preparing a composite long-fibrous spunbond non-woven fabric. The method comprises the steps of: respectively melting a core component and a sheath component using separate extruders, spinning the respective polymers through a composite spinning nozzle, giving cooling air to the spun filament to be solidified, and then making the solidified filament into a stretched filament having a small fiber diameter through a stretching procedure; integrating the stretched filament on a porous screen belt, which is continuously driven, to form a non-woven web; and binding the integrated non-woven fabric webs by various methods such as thermal bonding to give shape stability to the non-woven fabric webs, wherein the spinning is performed by adding a phosphorus-based antioxidant as an antioxidant contained in the sheath component. According to the method for preparing the eco-friendly composite long-fibrous non-woven fabric containing a plant-derived composition to improve productivity of the present invention, the phosphorus-based antioxidant is added as an antioxidant contained in the sheath component, thereby remarkably reducing yarn cutting and defects at the time of spinning, and thus improving process stability and increasing productivity of the eco-friendly non-woven fabric.

    • PURPOSE: Non woven fabric for polyester textile for adsorption of an organic medium and a method for preparing the same are provided to remove the organic medium rapidly remaining in various printed circuit boards. CONSTITUTION: A method for preparing non woven fabric for polyester textile for adsorption of an organic medium includes a step for forming a non woven fabric laminate and a step for compressing the woven fabric laminate at a temperature of 130~200 °C and with the pressure of 40~80 kg/cm^2 between thermal compression rolls. The nonwoven fabric laminate includes an internal non-woven layer and an outer non-woven layer. The internal non-woven layer is comprised of ethylene terephthalate polymer materials gained by spinning, cooling and drawing ethylene terephthalate, an ethylene terephthalate polymer, and a copolymer of isophthalic acid.
