The invention relates to a composite needling nonwoven fabric using various materials and a manufacturing method thereof. The composite needling nonwoven fabric using various materials is manufactured by layering more than two layers of nonwoven fabrics which are composed of materials that are different from each other, performing thermal melting and adhesion processes on a calender, and needling and tangling. The composite needling nonwoven fabric using various materials of the invention has not only excellent chemical resistance, drug resistance, acid resistance, and alkali resistance, but also excellent mechanical properties, and therefore is applicable to moist environment or coast civil materials. |
