The present disclosure provides an additive for a spunbond nonwoven geotextile and a geotextile. The additive for a spunbond nonwoven geotextile includes titanium dioxide, tris(2,4- di-tert-butylphenyl)phosphite, tetrakis (3,5-di-tert-butyl-4-hydroxy) phenylpropanoic acid pentaerythritol ester, N,N'-ethylenebis(stearamide), zinc stearate, and hard acid ester. The additive can be added during a process of preparing a geotextile with polyethylene terephthalate. The additive can effectively improve the aging resistance of a light-weight geotextile fabric. When the existing geotextiles are used in a construction process, it is necessary to take activity-maintaining measures such as covering and light avoiding. When used outdoors, the geotextile prepared by the present disclosure does not require light-avoiding protection measures, which saves a lot of manpower, materials, and financial resources. 20 24 22 01 08 26 S ep 2 02 4 A B S T R A C T T h e p r e s e n t d i s c l o s u r e p r o v i d e s a n a d d i t i v e f o r a s p u n b o n d n o n w o v e n g e o t e x t i l e a n d a g e o t e x t i l e .
