Problems solved by technology

[0004] Since the melt usually has a high temperature of several hundred degrees Celsius when it is sprayed from the spinneret, if it is directly cooled rapidly, it will affect the crystallization properties of the polymer in the filament. , and the control of the air volume in the slow cooling process is the most critical, but the flow of cooling air in the usual cooling air supply process will bring adverse external disturbances to the filaments, thereby affecting the quality of the filaments

Abstract

The invention discloses a slow-cooling blowing device which comprises an air room, and an air supply channel communicating with the bottom face of the air room, wherein the air supply channel is connected to an air regulation device by an air supply pipeline; the air regulation device is connected to a refrigerant fan by a blowing pipeline; and multiple air vents are distributed uniformly along the circle of the inner side face of the air room. The slow-cooling blowing device is characterized by accurate air capacity control, dispersed blowing, and uniform and non-concentrated air capacity; disturbance brought by flowing of cooling air to filaments is avoided, and thus consistency of filament diameters of fiber strands, and uniformity of the strands are ensured; and fiber quality is improved, and thus product quality is increased.

Description

technical field [0001] The invention relates to the field of structural design and application of fiber processing devices, in particular to a slow cooling blowing device. Background technique [0002] Melt spinning is one of the main preparation methods of chemical fibers. Melt spinning generally includes the following steps: melting of spinning raw materials, metering of melted spinning solution, extrusion of spinning solution, cooling of spinning solution to form primary fibers, drawing, Oiled and coiled. [0003] The factor that has the greatest influence on the quality of the as-spun fibers in the melt spinning process is the process of cooling the spun melt fine stream sprayed from the spinneret into the as-spun fibers. The quality of the melt is accompanied by the recrystallization of the polymer and the redistribution of the lattice during the cooling process of the melt. Therefore, the cooling quality directly determines the quality of the finished filament. [00...
