Problems solved by technology
[0007] However, when the current general-purpose nylon spinning production line produces fine denier yarns, the production cost is very high due to the low output; for finer nylon fine denier filaments, such as 5 denier and 8 denier filaments, most of China's Spinning production line cannot be done at all due to configuration problems (such as tunnels, etc.) or the evenness of the product is very poor

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited only to the examples.
[0021] combine figure 1 Shown, a kind of spinning equipment that is used for fine denier filament fiber, comprises hopper 1, screw extruder 2, spinning box 3, and hopper 1 is arranged on the feed inlet top of screw extruder 2, and spinning box 3 is located below the discharge port of the screw extruder 2. A metering pump and a spinneret 5 are arranged inside the spinning box 3 , and a cluster 6 is arranged below the spinneret 5 . Between the spinneret 5 and the buncher 6, there are also several groups of netters 4, the number of groups of netters 4 corresponds to the ratio of the final filament, for example, one split into two at the end, then two groups of netters 4, One point four, then four groups of network devices 4 are set, which can be changed according to actual needs. There are at lea...

The invention discloses spinning equipment and method for a fine denier filament fiber. The spinning equipment comprises a spinning case and a cluster device arranged under the spinning case, wherein a filament spraying plate is disposed in the spinning case; a plurality of wire stitching devices are arranged between the filament spraying plate and the cluster; and the filaments sprayed by the filament spraying plate enter each wire stitching device and are then clustered to the cluster device. A pre-filament dividing step is also included between the filament spraying step and the clustering step. In the pre-filament dividing step, after filament spraying, the long filament is divided into a plurality of equal sections; and each section long filament enters the wire stitching device for stitching and is then clustered. The beneficial effects of the spinning equipment and method are that filaments are pre-separated, then clustered and separated, so fine denier filaments of different thinness can be achieved; the filament is pre-divided into equal sections, so great evenness is achieved for the filament after the division; high yield and great quality can be achieved; and the spinning equipment and method are suitable for production of filament products with fineness under 15 denier.
Description
technical field [0001] The invention relates to the technical field of textile machinery, in particular to a spinning device and a spinning method for fine-denier filament fibers. Background technique [0002] Fiber refers to a substance composed of continuous or discontinuous filaments, including synthetic fibers such as nylon, polyester, and vinylon. At present, nylon 6 (PA6) production process is generally adopted in nylon factories. Nylon 6 is mainly made of PA6 dry chips through melt spinning, drafting, and winding to produce filaments of various specifications and uses. The basic process of PA6 products is: dry slicing—feeding hopper—intermediate silo—screw extruder—spinning box—melt metering pump—spinning assembly, spinneret—network device— Drafting roller of winding machine—coil forming of winding head—finished product inspection—finished product—packaging—warehousing. [0003] Among them, slice feeding and extrusion steps: PA6 dry slices are unpacked and added to ...
