After the filament bundle passes through the network nozzle, the compressed air of the nozzle acts to produce DTY network yarn with different network styles, or the compressed air is closed to produce non-network yarn.
The oiling device comprises an oiling plate, guide rollers and conveying rollers, wherein the oiling plate comprises a plurality of oiling channels which are distributed at intervals along the width direction of the oiling plate, each oiling channel comprises a cylindrical A channel, a circular table-shaped B channel, a cylindrical C channel and a circular table-shaped D channel which are sequentially communicated with each other, the diameter of each A channel is smaller than that of each C channel, the small opening of each B channel is connected with the corresponding A channel, the large opening end of each D channel is communicated with the corresponding C channel, the oiling plate is provided with a nozzle extending into each C channel in a penetrating manner, the lower surface of the oiling plate is recessed to form an oil outlet channel communicated with each C channel, the guide rollers and the conveying rollers are respectively arranged on two sides of the length direction of the oiling plate, fibers enter from the A channels and pass through the D channels 180 degrees and then enter the D channels, then exit from the A channels, and then pass through the conveying rollers 180 degrees and are output.
The shaft speed of the first roller is 300-600m/min, so that the filament is heated to a vitrified state so as to be convenient for deformation.

Detailed Description
The invention is further described with reference to the drawings and detailed description which follow:
example 1
A method for producing regenerated high-fluffiness high-strength DTY,
a, placing the regenerated semi-dull POY on a raw silk frame, and introducing a silk bundle into a first roller through a silk guide pipe and a silk guide device, wherein the shaft speed of the first roller is 300m/min;
b, inputting the tows into a deformation hot box for treatment, wherein the heating temperature of the deformation hot box is 160 ℃;
c, cooling the heated and deformed tows by a cooling plate, and then putting the cooled tows into a false twister for twisting and untwisting, wherein the untwisting tension is 10g; then sequentially passing through a tension sensor, a second roller, an auxiliary roller, a network nozzle, a shaping hot box, a yarn guide and a third roller, winding 2 circles between a leather roller and the yarn guide roller when the yarn bundle enters the second roller, wherein the shaft speed of the second roller is 570m/min, the shaft speed difference ratio of the second roller to the first roller is 1.9, the shaft speed of the auxiliary roller is larger than that of the second roller, the shaft speed of the auxiliary roller is 620m/min, the temperature of the shaping hot box is 170 ℃, and the yarn bundle passes between the leather roller and the steel roller of the third roller in a direct pressing mode after entering the third roller, and the shaft speed of the third roller is 6710m/min;
and d, finally, oiling the tows through an oiling device, and then, winding the tows in a winding device to form the regenerated high-fluffiness high-strength DTY with the winding speed of 580m/min.
In both the manufacturing process and the post-processing process of the polyester fiber, the fiber is required to have certain surface characteristics such as antistatic property, smoothness, cohesion and the like, and the oiling is aimed at improving the surface characteristics of the fiber. The existing oiling mode is to apply oil by using a pair of oiling rollers, or the fiber passes between a pair of oiling rollers and is coated on the tow by using the rotation of the oiling roller immersed in the lower part of the oil tank, or the fiber passes from the bottom end of a single oiling roller and is immersed in the oil for oiling. In the former method, as the oiling roller is positioned below the fiber, the contact area is small, so that only the lower surface of the fiber can be smeared with oil, the oiling is uneven, and the problems of broken filaments, hanging filaments or thorns and the like are easily caused; in the latter method, the oiling roller is soaked in the oil, the surface of the silk thread is often carried with excessive oil, the excessive oil needs to be scraped, but certain damage is caused to the fiber when the oil is scraped, especially for high-fluffiness fiber, the damage is larger, and the oil in the oil groove is easily polluted by an open oil groove.

The guide roller 2 and the conveying roller 3 are arranged along the width direction of the oiling plate 1, and the bottom end of the guide roller 2 is flush with the top end of the conveying roller 3. The structural design of the oiling device can enable tows to pass through the oiling channel 11 back and forth, oiling on the front side and the back side is achieved, oiling uniformity is guaranteed, meanwhile, the structural design of the oiling channel 11 also enables the sprayed oiling agent to be rapidly collected into the C channel 113 and flow out, the oiling agent spraying mode also reduces the consumption of the oiling agent, and pollution caused by the fact that a large amount of oiling agent is placed in an open mode is avoided.
