The invention discloses double-layer fabric containing polytetrafluoroethylene fiber and application of the double-layer fabric. The double-layer fabric is formed by connecting and bonding a polytetrafluoroethylene fiber layer and a fiber layer formed by other fiber into a whole through bonding points. The fineness of the fiber forming the polytetrafluoroethylene fiber layer ranges from 50 dtex to 1400 dtex, the twist of the fiber forming the polytetrafluoroethylene fiber layer ranges from 0 t/m to 800 t/m, and other fiber is selected from one or more of cotton, polyester, polyamide and polyphenylene sulfide. The low-friction-coefficient fabric has the advantages of being small in friction coefficient, high in stripping strength, small in stress deformation and simple in process. The double-layer fabric can be applied to mechanical moving parts.
