The invention discloses a waterproof acidproof alkali-proof fiber rope and a production method thereof and relates to the field of ropes. The waterproof acidproof alkali-proof fiber rope comprises a shell (1), a rope core (2) and a waterproof acidproof alkali-proof coating (3). The rope core (2) is disposed inside the shell (1). The waterproof acidproof alkali-proof coating (3) is arranged outside the shell (1). The shell (1) is made by weaving half S-directionally-twisted polypropylene fiber strands and half Z-directionally-twisted polypropylene fiber strands. The rope core (2) is a thermally-set combination of triple strands of nylon fiber filaments. The fiber rope includes the three layers from inside to outside; the process is simple to operate; the fiber rope is fine in water proofing, acid proofing, alkali proofing, corrosion resistance, and safety.
