摘要：
The present invention relates to a polyester nonwoven fabric for civil engineering and a method for manufacturing the same. The method for manufacturing the polyester nonwoven fabric for civil engineering according to the present invention is a polyester nonwoven fabric manufacturing method by which a polyester polymer is spun, filament stretching is performed through an ejector, and then a web is formed on a conveyor belt through filament opening based on collision plate-based collision and mechanical strength is given by means of thermal compression or needle punching and form stability is given by means of post-processing or calendar processing during the manufacturing. One including a master batch containing a UV stabilizer is used as the polyester polymer and a hydrophilic agent is applied to its surface after the filament stretching during the manufacturing. According to the polyester nonwoven fabric for civil engineering and the method for manufacturing the polyester nonwoven fabric for civil engineering according to the present invention that has the configuration described above, the UV stabilizer and the hydrophilic agent are added during the manufacturing of the nonwoven fabric for civil engineering. Accordingly, in a case where the nonwoven fabric is used after the manufacturing, the nonwoven fabric that is used is capable of maintaining its strength even after it is left out in the open air for long due to halted construction. In addition, water drainage can be smoothly performed even in rain because of the hydrophilic agent, and thus damage attributable to water can be reduced. Furthermore, the present invention can be useful for soil loss prevention and as a soil bag or a vegetation mat, and thus is capable of dealing with problems of the related art described above.COPYRIGHT KIPO 2017본 발명은 토목용 폴리에스테르 부직포 및 그 제조방법에 대한 것으로, 상기한 본 발명의 토목용 폴리에스테르 부직포의 제조방법은 폴리에스테르 중합체를 방사하고 이젝터를 통하여 필라멘트를 연신시킨 후 충돌판의 충돌에 의한 필라멘트 개섬으로 컨베이어벨트 상에 웹을 형성시켜 열압착하거나 니들펀칭에 의해 기계적
