Sucking laminar flow equipment achieving uniform spinning

Abstract

The invention discloses sucking laminar flow equipment achieving uniform spinning. The sucking laminar flow equipment comprises a spinneret plate, a lateral blowing device, a monomer sucking device and a laminar flow device; the spinneret plate sprays out spinning silk, and the spinning silk is drawn and wound by a winding device arranged at the opposite side of the spinneret plate; the lateral blowing device is arranged at the back side of the spinning silk and used for cooling the spinning silk in a blowing mode; the monomer sucking device is arranged at the front side of the spinning silk and used for sucking polymeric monomers sprayed by the spinneret plate; the laminar flow device used for guiding air flow is installed at the front end of the monomer sucking device, located between the spinning silk and the monomer sucking device and composed of multiple air flow channels which are arranged in a stacking mode, and the air flow channels are perpendicular to the spinning silk. According to the sucking laminar flow equipment achieving uniform spinning, the monomers can uniformly flow in the sucking process, therefore, tiny shaking of silk strands is generated, and then the physical properties such as evenness and dyeability of the silk strands can reach the standard.

Description

technical field [0001] The invention relates to the technical field of spinning equipment, in particular to a uniform suction laminar flow device for spinning. Background technique [0002] In the production of chemical fiber spinning, the polymer material is usually melted, and then sprayed out from the spinneret of the spinneret to form spinning, and the spinning from the spinneret is carried out by the winding device on the opposite side of the spinneret Pull and wind. Due to the high spinning temperature at the nozzle of the spinneret, it is necessary to cool the chemical fiber spinning with rear blowing, so that the spinning sliver jetted from the spinneret is even and dry. Molecular monomers and macromolecular monomers are easy to attach to the spinning, making the spinning evenly dry. Therefore, it is necessary to use a monomer suction device to suck the macromolecular monomers on the front side of the spinneret nozzle before spinning. [0003] Such as figure 1 As ...

Problems solved by technology

[0004] Yet the defective of described spinning cooling suction equipment is: because chemical fiber spinning is generally ultra-fine denier, multi-F number specification, side air blowing device 20 is to chemical fiber spinning air cooling, and monomer suction device 30 is to chemical fiber spinning. Spinning 40 draws air to suck the macromolecular monomer ejected from the spinneret 10 outlets, that is, there is side blowing cooling on the entire spinning 40 rear side, and only the spinneret 10 outlets are on the spinning 40 front side. The unit suction device 30 performs suction, so that the wind direction of the side blowing produces a radian instead of a straight line, so that the force on the spinning 40 is uneven, which in turn causes the filaments to vibrate violently, and the thickness of the filaments is uneven, which inevitably makes the filaments The physical properties such as dryness and uniform dyeing cannot meet the standards
