Embodiment 1

[0015] Such as figure 1 As shown, the production method of the ultra-low shrinkage glossy FDY described in this embodiment uses the glossy polyester melt as raw material, transports the glossy polyester melt into the melt cooler, and utilizes the melt cooler to After the melt is cooled, it is sent to the spinning box 1, and after being metered by the metering pump, it is filtered by the spinning assembly in the spinning box 1 and then extruded. Triangular, after the spinning is cooled by the side blowing process, the tow enters the winding tanker for oiling 2, pre-network 3, double-roll heating 4, double-roll shaping 5, main network 6, post-heating plate 7 heating, and finally package forming 8 . The bright polyester melt conveying temperature is 279°C, and the temperature of the spinning box 1 is 290°C.

[0016] The temperature of the two heat rollers in the process of the double roller heating 4 is between 80°C.

Embodiment 2

[0020] The production method of the ultra-low shrinkage glossy FDY described in this embodiment uses the glossy polyester melt as a raw material, transports the glossy polyester melt into the melt cooler, and uses the melt cooler to cool the melt Finally, it is sent into the spinning box 1, and after being metered by the metering pump, it is filtered by the spinning assembly in the spinning box 1 and then extruded. After the silk is cooled by the side blowing process, the tow enters the winding tanker for oiling 2, pre-internetting 3, double-roll heating 4, double-roller shaping 5, main network 6, post-heating plate 7 heating, and finally package forming 8. The bright polyester melt conveying temperature is 279°C, and the temperature of the spinning box 1 is 290°C.

[0021] The temperature of the two heat rollers in the process of the double roller heating 4 is between 100°C.

[0022] The temperature of the two hot rollers during the double-roll shaping process 5 is between 1...

Embodiment 3

[0025] The production method of the ultra-low shrinkage glossy FDY described in this embodiment uses the glossy polyester melt as a raw material, transports the glossy polyester melt into the melt cooler, and uses the melt cooler to cool the melt Finally, it is sent into the spinning box 1, and after being metered by the metering pump, it is filtered by the spinning assembly in the spinning box 1 and then extruded. After the silk is cooled by the side blowing process, the tow enters the winding tanker for oiling 2, pre-internetting 3, double-roll heating 4, double-roller shaping 5, main network 6, post-heating plate 7 heating, and finally package forming 8. The bright polyester melt conveying temperature is 279°C, and the temperature of the spinning box 1 is 290°C.

[0026] The temperature of the two heat rollers in the process of the double roller heating 4 is between 90°C.

[0027] The temperature of the two hot rollers in the process of the double roller setting 5 is betwe...

Abstract

The invention relates to the technical field of production of fiber products, in particular to a production method of ultralow shrinkage bright FDY. Light polyester melt is taken as the raw material and is delivered to a melt cooler, the melt is delivered to a spinning manifold after cooled by the melt cooler, the melt is extruded after metered by a metering pump and filtered by a spinning component in the spinning manifold, a spinneret plate is deigned in a special three-leaf shape, the fiber cross section is in a regular triangle shape, after spin is cooled by lateral blowing process, a tow enters a winding oil wheel for oiling, pre-interlacing, double roller heating, double roll shaping, main interlacing and rear heating plate heating are performed, and finally package molding is performed. According to the production method of the ultralow shrinkage bright FDY, a full drawing bright FDY product with the waste water shrinking percentage lower than 3% is produced on conventional bright FDY equipment.

Description

technical field [0001] The invention relates to the technical field of production of chemical fiber products, in particular to a production method of ultra-low shrinkage glossy FDY. Background technique [0002] The boiling water shrinkage index of conventional bright FDY products can only be controlled at about 7%. Contents of the invention [0003] The object of the present invention is to provide an ultra-low shrinkage glossy FDY production method capable of reducing the shrinkage rate of glossy FDY products in order to solve the deficiencies of the above technologies. [0004] In order to achieve the above purpose, the production method of the ultra-low shrinkage glossy FDY designed by the present invention uses the glossy polyester melt as raw material, transports the glossy polyester melt into the melt cooler, and uses the melt to cool The melter cools the melt and sends it into the spinning box. After being metered by the metering pump, it is filtered by the spinni...
