Problems solved by technology
When the acetate fiber is spun and formed, the higher the single denier, the more difficult it is to bend and deform. A crimping equipment is suitable for a certain range of fiber single denier. If it exceeds this range, it will not be able to produce qualified tow products.

Embodiment Construction
[0021] Such as Figure 1~4 Among them, a device for improving the forming quality of high single-denier acetate tow includes a steam box, and the steam box is arranged before the crimping device 12, and the structure of the steam box is:
[0022] A cavity is provided between the loam cake 1 and the lower bottom 5. The loam cake 1 and the lower bottom 5 are integrally elongated. The two ends of the cavity are provided with thread openings 3 for the tow 7 to pass through. The best thread opening 3 only needs to be Slightly larger than the cross-section of the tow 7, a steam pipe 6 is provided below the thread opening 3, and an even air orifice 11 is provided above the steam pipe 6 below the silk opening 3, so that the steam can evenly contact the tow 7. The bottom of the lower bottom liner 4 of the bottom 5 is provided with a condensed water discharge port 8, and the condensed water generated by steam is discharged from the condensed water discharge port 8.

The invention discloses a device for improving the forming quality of a high single denier cellulose acetate fiber strand. A steam box is arranged in front of a curling device, and is structurally characterized in that a cavity is formed between an upper cover and a lower bottom, the two ends of the cavity are provided with fiber channel ports for the fiber strand to pass through, a steam pipe is arranged below the fiber channel ports, the position which is below the fiber channel ports and above the steam pipe is provided with an air uniformizing hole plate, and the bottom of a lower bottom lining of the lower bottom is provided with a condensate water outlet. According to the device for improving the forming quality of the high single denier cellulose acetate fiber strand, the steam box is arranged, the application range of the curling device is widened, and an existing curling machine suitable for 3.0-3.5 deniers of fiber strands can be suitable for producing 5.0 deniers of fiber strands.
Description
technical field [0001] The invention relates to a forming process in the chemical fiber spinning process, in particular to a device for improving the forming quality of high single-denier acetate fiber bundles in the spinning and forming process of acetate fiber. Background technique [0002] Denier is the weight in grams of a 9000-meter-long silk at a given moisture regain, and single denier is the linear density of a single filament. When the acetate fiber is spun and formed, the higher the single denier, the more difficult it is to bend and deform. A crimping equipment is suitable for a certain range of fiber single denier. If it exceeds this range, it will not be able to produce qualified tow products. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for improving the forming quality of high single-denier acetate tow, which can expand the scope of application of crimping devices, so that crimping devi...
