Problems solved by technology

[0003] The conventional hollow single fiber of the spinneret on the market now has only one hollow state. In the production of virgin polyester fiber, it is very easy to produce, but it cannot meet people's requirements, especially in the recycled and environmentally friendly polyester fiber industry. International clothing brands have proposed to replace virgin polyester fibers with recycled polyester fibers, so it is necessary to provide a spinneret for the production of hollow suction and discharge filaments

Embodiment 1

[0032] like Figure 1~3 As shown, it is a schematic structural diagram of a spinneret for the production of a hollow suction and discharge filament in a preferred embodiment of the present invention. A spinnerette for the production of a hollow suction and discharge filament in this embodiment includes a spinneret spinneret 10 , the spinneret spinneret 10 is composed of the first plate body 101, the second plate body 102 and the suction and discharge hole 30 in the hollow suction and discharge hole, the lower end surface of the first plate body 101 and the second The upper end faces of the two plates 102 are fixedly connected.

[0033] The first plate body 101 is provided with a spinneret hole 20, the upper end of the spinneret hole 20 is provided with a chamfer, and the lower end of the spinneret hole 20 is smaller than the diameter of the middle section, and the upper end of the spinneret hole 20 is The lower end is provided with a hollow suction and discharge hole 30 in th...

Embodiment 2

[0038] like Figure 5-6 As shown, it is a schematic structural diagram of a spinneret for the production of hollow suction and discharge of another preferred embodiment of the present invention. The spinneret for the production of a hollow suction and discharge of the present embodiment is added in Example 1. The replaceable structure 40 is installed on the upper end of 102 , and the replaceable structure 40 includes a third plate 404 and a hole 402 .

[0039] The third plate body 404 is provided with a plurality of threaded holes, the outer wall of the hole body 402 is provided with threads, and the top of the hole body 402 is provided with a hexagonal hole 403 , and the hexagonal hole 403 communicates with 20 .

[0040] In this embodiment, through the threaded connection between the hole body 402 and the threaded hole 401, the effect that each 20 can be replaced at any time is achieved. When a certain 20 is damaged, it is more convenient to replace which one needs to be repl...

Embodiment 3

[0042] The present invention also provides a special process for hollow filament suction and discharge including:

[0043] By making a special double C-type spinneret, using a special process in the process of producing recycled fibers, after many times of research, the discarded plastic bottles are dried at a drying temperature of 150°C for 6 hours, and then melted at a temperature of 270-290°C During the process, filter twice to remove impurities, control the viscosity of the melt IV=0.692+ / -0.05, melt spinning, pass through the assembly (assembly pressure of 0.18-0.21mpa) equipped with a custom spinneret and blow through the blower The temperature is 25°C, the wind speed is 0.75+ / -0.05M / S, the fiber is cooled to the status of '8', and the POY yarn is produced at a speed of 2500m / min, and the temperature is 25°C, and the humidity is 40%. Remove the stress of the tow, and then add and eject the DTY75D / 48F spinning '8' hollow fiber at a speed of 500-550m / min on the texturing m...

Abstract

The invention discloses a spinneret plate for producing hollow suction and discharge filaments, and belongs to the technical field of chemical fiber textile. The spinneret plate for producing the hollow suction and discharge filaments comprises a spinneret plate body; the spinneret plate body is formed by combining a first plate body, a second plate body and hollow suction and discharge filament holes; the lower end surface of the first plate body is fixedly connected with the upper end surface of the second plate body; each hollow suction and discharge filament hole comprises a connecting plate; C-shaped holes are formed in the two sides of each connecting plate; the length of the connecting plate is 0.1 mm, and the tolerance is + / -0.01 mm; and the diameter of the outer ring of each C-shaped hole is 1.4 mm, the diameter of the inner ring of each C-shaped hole is 1.26 mm, and the angle between the notch of each C-shaped hole and the central horizontal line of the corresponding C-shaped hole is 60 degrees. Through structural design of hollow filament suction and discharge holes, made cellosilk is 8-shaped, and the 8-shaped cellosilk has the advantages that clothes made of the 8-shaped cellosilk are warm, stereoscopic impression is better, heat dissipation effect is better, the clothes are warm, and body sweat can be easily discharged.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber textiles, and in particular relates to a production spinneret for hollow yarn suction and discharge. Background technique [0002] The present situation is that our living standard is getting better and better, and we have higher and higher requirements for the function of clothes. Most of the end faces of existing chemical fibers are round, which is convenient for production. But there is a certain gap from our dress requirements. People require functionality, hollow moisture absorption and perspiration. In winter, the requirements for clothing should not only keep warm but also easily discharge body sweat to keep the body refreshed. [0003] The conventional hollow single fiber of the spinneret on the market now has only one hollow state. In the production of virgin polyester fiber, it is very easy to produce, but it cannot meet people's requirements, especially in the recycled and envir...
