The invention discloses a low-foam gel-free high-capillary-effect anionic surfactant as well as a preparation method and application thereof, and belongs to the technical field of textile assistants. The anionic surfactant is fatty alcohol polyoxyethylene polyoxypropylene ether sodium sulfate, the molecular formula of the anionic surfactant is R-ExPyS, R is straight-chain or branched-chain C8-C18 alkane, the average value of x is 1-7, and the average value of y is 1-4. The anionic surfactant can be used as a textile pretreatment agent. The product is low in foam and easy to defoam, the foam performance of the product compounded with the nonionic surfactant is lower than that of the product independently used with the nonionic surfactant, and a synergistic phenomenon is generated, so that the product is not added with a defoaming agent when being used in a textile pretreatment auxiliary agent formula system; the product has no gel phase region and is convenient to use; the capillary effect of the product is hi
