Problems solved by technology

However, in the actual production process, when the wind passing through the rectifying plate cools the tow, it will be disturbed by the external wind and turbulent flow will occur, resulting in uneven cooling of the tow and low evenness, which seriously affects the production. The quality of nylon filament

Abstract

The invention discloses a side blowing device for improving the evenness of polyamide filament evenness. The side blowing device comprises a vertically arranged rectifying plate, a net cover which is fixedly arranged on the side face, close to a filament bundle, of the rectifying plate and a wind direction rectifying plate; the wind direction rectifying plate is fixedly arranged on the side face, far away from the rectifying plate, of the net cover, the wind direction rectifying device comprises two side plates, and multiple layers of drainage plates are arranged between the two side plates at intervals. The side blowing device for improving the polyamide filament evenness has the following advantages that by means of the wind direction rectifying device, subsection cooling and multiple subsection cooling are conducted on the filament bundle, blowing turbulence is reduced, the cooling effect of the filament bundle is improved, the evenness of the strands is improved, and the quality of the produced polyamide filaments is improved.

Description

technical field [0001] The present disclosure generally relates to the technical field of chemical fibers, in particular to nylon filaments, and in particular to a side blowing device for improving the evenness of nylon filaments. Background technique [0002] As a kind of textile fabric, nylon yarn has various types such as monofilament, strand, and special yarn. Because of its advantages such as relatively crisp, no pilling, no wrinkle, and convenient cleaning, it has been widely used in clothing and decorative fabrics. and other fields. In the traditional production process of nylon filament, the nylon melt passes through the spinneret to form multiple tows, and the tows need to be cooled before being wound up at the winding head. In the traditional device for producing nylon filaments, a side blowing device is provided on the lower side of the spinneret, and a rectifying plate is provided in the side blowing device, and the rectifying plate includes six transparent defo...
