Example Embodiment

[0024] Example 1

[0025] Reference figure 1 with figure 2 , The production method of 16f bright super coarse denier FDY fully drawn fiber, the production method includes the following steps:

[0026] S1. Using the bright polyester melt as the raw material, the bright polyester melt is first pressurized to 150~200Kg through the melt delivery pipe 1 by the booster pump, and then sent to the melt cooler. The bright polyester melt is cooled to 275°C~278°C and sent to the spinning box 2;

[0027] S2. The bright polyester melt after entering the spinning box 2 is measured by the metering pump and then transported to the spinning assembly in the spinning box through a thin pipe, filtered and extruded by the spinneret, and then passed through the side blowing device 3 Cool and solidify into nascent fibers;

[0028] S3. The nascent fiber in step S2 passes through the tunnel in turn to continue cooling 4. The winding tanker is oiled 5, the pre-network device 6, the first, second, third, and...

Example Embodiment

[0041] Example 2

[0042] In this example, the conveying temperature of the bright polyester melt in the melt conveying pipe is 279° C., and the remaining embodiments are the same as in Example 1.

[0043] A 16f bright ultra-coarse denier FDY fully drawn fiber produced in this embodiment has main technical indicators: strength of 4.35 cn / dtex, elongation at break of 29%, and unevenness (CV% value) of 1.06 %.

Abstract

The invention discloses a production method of bright and ultra-coarse denier 16f FDY fiber. The production method comprises the following steps: S1 a bright polyester melt as raw material passing through a melt conveying pipeline, being pressurized to 150-200kg by a booster pump and being sent to a melt cooler in sequence, and then the bright polyester melt being cooled to 275-278 DEG C by the melt cooler and being sent to a spinning manifold; S2 after being metered by the metering pump, the melt being sent to the spinning pack arranged in the spinning manifold through a thin pipeline and being filtered by the spinning pack, and then the melt being extruded by a spinnerette and being solidified and cooled to be an as-spun fiber by a cross air blasting device; S3 the as-spun fiber in the step of S2 being cooled by a cooling chimney, being oiled by a winding oil gear, passing through a prior network device, being stretched-set by a first, second, third and fourth hot rollers, passing through a main network device and being packaging by a winding head in sequence. The production method of bright and ultra-coarse denier 16f FDY fiber has the advantages of realizing the production of bright and ultra-coarse denier 16f FDY fiber as well as the possibility of producing high technical difficulty and value-added production on the basis of conventional equipment.

Description

technical field [0001] The invention relates to a production method of 16f glossy ultra-coarse denier FDY fully stretched fiber. Background technique [0002] Bright FDY conventional products have reached very high saturation in the chemical fiber market, and the profit margin is getting smaller and smaller. Therefore, it is necessary to develop super-conventional varieties to increase the economic benefits of the enterprise. We use the original equipment platform, give full play to the advantages of equipment, make bold innovations in technology, and produce 16f bright ultra-coarse denier FDY fully stretched fiber with high technical difficulty, which will increase new profit margins for enterprises. 16f bright ultra-coarse denier FDY fully drawn fiber has a monofilament fineness exceeding 15dtex, which is much higher than conventional varieties, and realizes the possibility of producing high-technical difficulty and high value-added products on the basis of conventional eq...
