Embodiment 1

[0025] refer to figure 1 and figure 2 , the production method of single cake 576f ultra-porous POY polyester filament, is characterized in that: described production method comprises the steps:

[0026] S1. Using semi-glossy polyester melt as raw material, first pressurize the semi-glossy polyester melt to 150-200Pa through the melt delivery pipeline through the booster pump, and then send it to the melt cooler. After the light polyester melt is cooled to 275°C-278°C, it is sent into the spinning box;

[0027] S2. The melt after entering the spinning box is metered by the metering pump, and then transported to the spinning assembly in the spinning box through a thin pipe, filtered, extruded through the spinneret, and then cooled and solidified by the ring blowing device to form primary fibers;

[0028] S3. The nascent fibers in step S2 are oiled sequentially through double-channel oil nozzles, and the network device increases the cohesion, and then the winding tension is co...

Embodiment 2

[0041] In this embodiment, the conveying temperature of the semi-gloss polyester melt in the conveying pipe is 279° C., and the other implementation methods are the same as those in Embodiment 1.

[0042] The 576f ultra-porous POY polyester filament produced by the present embodiment has main technical indicators: the strength is 2.55cn / dtex, the elongation at break is 126%, and the evenness unevenness (CV% value) is 0.96%.

Abstract

The invention discloses a production method of a single-cake 576f super-multihole POY (pre-oriented yarn). The production method comprises the following steps: S1. firstly feeding a semi-gloss polyester melt as a raw material into a melt cooler after the semi-gloss polyester melt passes through a melt delivery pipeline and is pressurized to 150-200Pa by a booster pump, cooling the semi-gloss polyester melt to 275-278 DEG C by the melt cooler and then feeding the semi-gloss polyester melt to a spinning manifold; S2. metering the melt entering the spinning manifold by a metering pump, then delivering the melt to a spinning pack in the spinning manifold by a thin pipeline to be filtered, then extruding the melt by a spinneret plate and then cooling and solidifying the melt into as-formed fibers by a circular air blow device; S3. after applying oil to the as-formed fibers in the step S2 by a double-passage nozzle and increasing the saturability of the as-formed fibers by a nozzle in sequence, controlling the tension till the tension required by the process by a godet integrated on a winding machine and then guiding tows into the winding machine to undergo package shaping. The production method can achieve production of the single-cake 576f super-multihole POY, thus greatly improving the production efficiency and effectively reducing the production cost.

Description

technical field [0001] The invention relates to a production method of single cake 576f ultra-porous POY polyester filament. Background technique [0002] At present, there are individual manufacturers of 576f varieties in the market, but they are all completed through joint stock technology, which has high production costs, low machine efficiency, and product quality does not meet high-quality requirements. In addition, in order to produce the 576f variety, some downstream customers also use the 288f variety for joint production, and the production efficiency is also severely restricted. We use large-diameter equipment to develop single-cake spinning 576f ultra-porous and fine-denier varieties, which greatly improves production efficiency, reduces production costs, and product quality is far superior to joint-stock products, filling the domestic and international chemical fiber industry.
