Unmanned automatic production equipment for wool-like nylon filament

Abstract

The invention provides unmanned automated production equipment for wool-like polyamide filaments. The equipment comprises support plates arranged on two sides of a well mouth. Tops of the two supportplates are equipped with a spinning side-blowing air box. Multiple special-shaped sectional spinneret plates with spinneret holes are arranged in the spinning side-blowing air box. The spinneret holesare rectangular. A cooling air direction adjusting assembly is arranged behind the two support plates. The cooling air direction adjusting assembly is used for adjusting air direction and speed of cooling air such that set angles are formed between filament sections extruded by the spinneret holes of the special-shaped sectional spinneret plates and a spinning window. With surfaces of the supportplates as the basis, air blowing angles range from 30 to 60 degrees. Air speed ranges from 0.3M / S to 0.5M / S. therefore, the overall filament sections are not uniformly cooled. Cooled filaments are oiled when passing through a spinning nozzle support frame, fixed by stretching through a filament guiding assembly and then roll into the wool-like polyamide filaments. The unmanned automated production equipment can produce the wool-like polyamide filaments which have stiffness or rigidity of wool and are elastically bent.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to unmanned automatic production equipment for wool-like nylon filaments. Background technique [0002] Due to its excellent physical properties, such as high strength, good temperature absorption and bright dyeing, nylon is widely used in the field of clothing. In recent years, the research and development of nylon 6 fiber, especially the research on its replacement of wool fiber, has developed rapidly. [0003] The traditional nylon fiber has a good hand feeling, but it is soft to the touch. To make wool-like properties, the problem of poor stiffness must be solved, and the fibers must have the same curved shape as wool and have a certain degree of elasticity. [0004] General polyamide civil multifilaments have a monofilament fineness between 1-3.5DPF. In order to improve the stiffness of the fiber, fully drawn FDY products must be used, and the monofilament fineness mus...

AI Technical Summary

Problems solved by technology

[0006] Ordinary nylon filaments are straight, which cannot reach the bending performance of wool. In the prior art, there is no production equipment capable of producing wool-like nylon filaments.
