Abstract: The present invention relates to an eco-friendly composite long fiber nonwoven fabric containing a composition derived from a plant and to a manufacturing method thereof. The method for manufacturing an eco-friendly composite long fiber nonwoven fabric containing a composition derived from a plant according to the present invention is a method for manufacturing a nonwoven fabric by spraying filaments constituting the nonwoven fabric in the shape of a sheath and a core, stacking the spun filaments on top of a belt to form a web, and performing thermo-compression or needle punching. The filaments are spun from two separate beams, A and B, in the shape of a sheath and a core. In beam A, the core component is polypropylene, the sheath component is polyethylene derived from a plant and the ratio of the core component to the sheath component is 50:50 to 80:20. In beam B, the core component is polypropylene, the sheath component is polyethylene derived from petroleum and the ratio of the core component to the sheath component is 50:50. The eco-friendly composite long fiber nonwoven fabric containing a composition derived from a plant, as configured above, uses filaments constituting the nonwoven fabric that is spun by two separate beams to have different compositions, thus stabilizing a process from the melt spinning of filament to web formation and mitigates the generation of cut yarn. Therefore, process stability is improved to increase the productivity of the eco-friendly nonwoven fabric and solve existing problems by improving properties such as tensile strength and stiffness.

Abstract: The present invention relates to a nonwoven fabric having improved air permeability and a manufacturing method thereof. The nonwoven fabric having improved air permeability according to the present invention is formed of a monolayered or multilayered long fiber nonwoven fabric combined by spraying filaments while arranging packs for spraying filaments with different fineness in parallel and thermally compressing the filaments according to a non-embossed pattern or an embossed pattern when polytrimethylene terephthalate (PTT) with viscosity of 0.8 to 1.2 and polyethylene terephthalate (PET) with viscosity of 0.6 to 0.8 are sprayed in the shape of a sheath and a core. The PTT nonwoven fabric having improved air permeability, as configured above, is manufactured by spraying filaments with different fineness using PTT as a main material and adding and mixing PET thereto and thus solves existing problems to have excellent air permeability in addition to proper durability and softness required for a multipurpose nonwoven fabric sheet. Therefore, the present invention provides a method for manufacturing a multipurpose nonwoven fabric more economically.
