The invention relates to a combination machine for open width oil removal, moist heat relaxation and pre-shrinking water rinse, which is applicable to the open width oil removal, pre-shrinking and refining water rinse processes of knitting, urethane elastic fiber, terylene, chinlon and combined fiber fabrics. The combination machine comprises an open width cloth feeding bracket (1), a double-oscillation water rinse tank (2), single rotating drum rinsing machines (3), a two-roll heavy padder (4) and an open width doffing cloth bracket (5) in turn from the front to back, wherein the number of the single rotating drum rinsing machines (3) is at least two groups, and an internal two-roll padder II (7) is arranged between adjacent two groups of single rotating drum rinsing machines (3). The combination machine is characterized in that: each group of single rotating drum rinsing machine (3) comprises a tank body II (3.1), a sink II (3.9), two guide rails (3.10), two water baffles (3.11), a netlike rotating drum II (3.2), a suspended tensioning rack (3.3) and a spraying pipe II (3.5); and the front of a rolling point of a roller (3.8) of the internal two-roll padder II is provided with positive and negative strippers (3.6). The combination machine can realize low-tension cloth delivery, and efficient cloth spread and edge toggle. Therefore, the combination machine can be applied to the fabrics with large elasticity.
