The invention provides a processing technology of a purified-cotton, high-count and weak-twist terry fabric. The processes of terry yarn processing, terry coiling, fast yarn coiling, weaving as well as bleaching and dyeing are adopted to produce the terry fabric with a better hand feeling from high-count cotton, wherein in the weaving process, a primary drying process is additionally performed, thereby effectively avoiding the phenomena of mildewing and the like of the coiled cloth, and improving the production efficiency. The invention also provides a loom for producing the purified-cotton, high-count and weak-twist terry fabric. The loom comprises a rack, and a cross beam, a harness frame mechanism, a beating-up mechanism and a cloth roller are arranged on the rack, wherein a tidying mechanism is arranged between the beating-up mechanism and the cloth roller, the tidying mechanism is transversely fixed on the rack, the tidying mechanism comprises a shell, the shell is of a clip-shaped structure, and a cloth penetrating hole for cloth to penetrate through is formed in the middle of the shell. A plurality of water absorption holes are uniformly distributed above and below the clothpenetrating hole and are used for absorbing water in the cloth passing through the tidying mechanism, thereby reducing the moisture in the cloth and reducing the mildewing phenomenon of the cloth.
