Problems solved by technology

[0005] However, the composite environment-friendly long-fiber nonwoven fabric containing the plant-derived composition of the conventional method is due to the reduction of CO 2 Emissions, so the environmental protection is better than the original polypropylene (PP) alone non-woven fabric, but the spinnability of the polymer is poor, the productivity is low, and there are problems that the physical properties of other non-woven fabrics cannot be satisfied. Therefore, in order to solve these problems tireless research

Embodiment 1

[0037] In one spinning box (Spinning Box A), polypropylene with a melting point of 165°C and a melt index (MI) of 35 was used as the core component, and polyethylene of vegetable origin with a melting point of 125°C and a MI of 20 was used as the core component. The temperature of the extruder for the sheath component and the core component is 230°C, and the extruder for the sheath component is 250°C. In this state, the raw materials are melted. In another spinning box (B spinning box), the melting point is set to Polypropylene with 165°C and MI of 35 is used as the core component, and petroleum-derived polyethylene with a melting point of 125°C and MI of 32 is used as the sheath component. The extruder temperature for the core component is 230°C, and the extruder for the sheath component The temperature is 230°C, and the raw material is melted in this state. The molten polymer moves through an independent flow path with the help of the distribution plate in the composite spin...

Embodiment 2

[0039] A nonwoven fabric was produced in the same manner as in Example 1, except that the ratio of the core component and the sheath component of the spinning beam A was configured at 70:30.

Abstract

The present invention relates to an environmental-friendly composite long-fiber nonwoven fabric containing a composition derived from a plant and to a manufacturing method thereof. The method for manufacturing an environmental-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 core sheath, stacking the spun filaments on top of a belt to form a web, and performing thermo-compression or needle punching. The method is characterized in that the filaments are spun in two separate spinning boxes A and B; in the spinning box 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 the spinning box 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; and the filaments in the shape of the core sheath. By adopting the method, stability is realized in the processes from long-fiber melt spinning to web forming, the filament breaking phenomenon is substantially improved, the process stability is improved, the productivity of the environmental-friendly nonwoven fabric is increased, and properties such as tensile strength and stiffness are improved.

Description

technical field [0001] The present invention relates to an environmentally friendly composite long-fiber nonwoven fabric containing a plant-derived composition and a manufacturing method thereof, and more specifically, to an environmentally friendly composite long-fiber nonwoven fabric containing a plant-derived composition and a manufacturing method thereof. The polymer that makes up the non-woven fabric contains polyethylene obtained by refining ethanol extracted from plants, thereby providing the effect of reducing carbon dioxide emissions due to the use of non-petroleum-based polymers, and making non-woven fabrics with a specific structure to improve the feel of the non-woven fabric The method for compounding environment-friendly long-fiber non-woven fabrics can improve the productivity and physical properties of the original composite environment-friendly non-woven fabrics containing plant-derived compositions. Background technique [0002] As global warming due to envi...
