Currently, terylene is the most rapidly developed fiber with the largest yield in synthetic fibers. And occupies a considerable specific gravity in the entire textile fiber. The terylene fabric has the advantages of high strength, good elasticity, good wear resistance, good practicability and the like, and is popular with consumers. At present, polyester fabrics are generally dyed by disperse dyes, oiling treatment is carried out on polyester fibers in the spinning process in order to prevent the adhesion of the fibers, and the dyeing effect is seriously influenced by the presence of oil agents during dyeing. Therefore, before dyeing the disperse dye, a pretreatment (refining) is required to remove the oil agent. When the disperse dye is used for dyeing terylene, the dyeing is generally carried out under the condition of weak acidity (pH is about 5), which is beneficial to dye. The oil removal and decontamination of the polyester fiber are generally carried out under the alkaline condition (the pH value is more than 11), the stronger the alkalinity is, the better the oil removal effect is, and most of disperse dyes can generate color change phenomenon when being subjected to alkali and seriously affect the dye-uptake.

The fixing frame 51 is in an L-shaped plate shape, one end of which is horizontally arranged and fixed with the outer side wall of the casing 1, and the other end of which is vertically arranged upwards. The driving shaft 52 is a circular shaft, the axis of which is parallel to the axis of the rotating rod 47, one end of the driving shaft 52 is rotatably connected with the outer side wall of the casing 1, and the other end is rotatably connected with the inner side wall of the fixing frame 51. The motor 53 is a servo motor, and is disposed on the fixing frame 51 and fixed to the outer side wall of the fixing frame 51 away from the housing 1, the axis of the output shaft of the motor 53 is overlapped with the axis of the driving shaft 52, and the end of the output shaft of the motor 53 is fixed to the end of the driving shaft 52 connected to the fixing frame 51. The first driving gear 54 is a spur gear, and is sleeved on the end of the second guiding roller 22 penetrating through the casing 1 and fixed with the second guiding roller 22. The second driving gear 55 is a spur gear, which is sleeved on the end of the rotating rod 47 penetrating through the housing 1 and fixed therewith, the fourth driving gear 57 is also a spur gear, the fourth driving gear 57 is sleeved on the driving shaft 52 and fixed therewith, and the fourth driving gear 57 is meshed with the second driving gear 55. The third driving gear 56 is an incomplete gear, which is sleeved on and fixed with the driving shaft 52, a toothed section 561 and a non-toothed section 562 which are connected with each other are arranged on the periphery of the third driving gear 56, the toothed section 561 is a gear tooth of a straight gear, the toothed section 561 is meshed with the first driving gear 54, the non-toothed section 562 is an arc-shaped gear surface, and the non-toothed section 562 is not in contact with the first driving gear 54. As shown in fig. 3, when the motor 53 is started, the output shaft of the motor 53 drives the driving shaft 52 to rotate, so that the fourth driving gears 57 drive the second driving gears 55 to rotate, respectively, and the toothed section 561 of the third driving gear 56 drives the first driving gear 54 to rotate, thereby driving the cam 48 and the second guiding roller 22 to rotate, so that the cloth pressing device 4 and the guiding device can be started simultaneously; in addition, when the pressing water plate 42 presses the dacron, the vibrating rod 44 is located at the lowest position of the moving stroke of the vibrating rod, and at this time, the toothless section 562 on the third driving gear 56 rotates to the meshing position of the third driving gear 56 and the first driving gear 54, so that the second guide roller 22 is not driven by the motor 53 at this time, and the dacron on the water permeable plate 41 is not pulled by the second guide roller 22 when being pressed by the pressing water plate 42, and the dacron is prevented from being torn off.

The implementation principle of the embodiment is as follows: in step S1, the polyester fabric is degreased with an alkaline refining agent, so that the alkaline refining agent is attached to the polyester fabric, and then in step S2, the polyester fabric is sprayed in the housing 1 and then the water in the polyester fabric is squeezed out, so that the alkaline refining agent is separated from the polyester fabric along with the water, thereby preventing the polyester fabric from carrying the alkaline refining agent in step S3 to neutralize the dye, and being beneficial to preventing the alkaline refining agent from affecting the printing and dyeing effect of padding the disperse dye.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
