Embodiment 1

[0027] The following examples will further illustrate the fine-denier bright nylon 6 high-oriented fiber spinning process, but not as a limitation of the present invention.

[0028] Below in conjunction with process flow chart for further explanation.

[0029] Spinning equipment and supporting devices, including screw extruder 1, measuring head 2, melt distribution pipe 3, spinning box 4, spinning metering pump 5, spinning assembly 6, side blowing device 7, oiling device 8 , winder 9 and biphenyl steam generator 10.

[0030] Technological process: 1005kg of dry nylon 6 slices (calculated as 1000kg product) enter the screw extruder 1, and after being extruded and melted, it becomes a spinnable nylon 6 melt. In the screw extruder 1, it is divided into five temperatures In the control area, the heating temperature of the first zone is 245°C, the heating temperature of the second zone is 250°C, the heating temperature of the third zone is 255°C, the heating temperature of the fou...

Embodiment 2

[0033] 1) 1010kg of dry nylon 6 slices (calculated as 1000kg product) are heated, extruded, and melted into a melt in a screw extruder with a rotation speed of 30 rpm and a heating temperature of 245°C. The screw extruder is divided into Five temperature control zones, the heating temperature of the first zone is 240°C, the heating temperature of the second zone is 245°C, the heating temperature of the third zone is 250°C, the heating temperature of the fourth zone is 255°C, the heating temperature of the fifth zone is 257°C, the nylon 6 produced by the screw extruder The temperature of the melt is 257°C. 2) The nylon 6 melt is kept warm by the gas phase heat medium in the melt pipeline, and is sent to the spinning box by a pipeline of equal length outside the box, and is metered by the spinning metering pump. The supply volume of the metering pump is 5 g / min, the number of rotations is 8 rpm, and then the nylon 6 melt is evenly distributed to the spinning assembly through the ...

Embodiment 3

[0038] 1) 990kg of dry nylon 6 slices (calculated as 1000kg product) are heated, extruded, and melted into a melt in a screw extruder with a rotation speed of 80 rpm and a heating temperature of 265°C. The screw extruder is divided into Five temperature control zones, the heating temperature of the first zone is 250°C, the heating temperature of the second zone is 255°C, the heating temperature of the third zone is 260°C, the heating temperature of the fourth zone is 260°C, the heating temperature of the fifth zone is 265°C, the nylon 6 produced by the screw extruder The temperature of the melt is 265°C. 2) The nylon 6 melt is kept warm in the melt pipeline by a gas-phase heat medium, and is delivered to the spinning box by a pipeline of equal length outside the box, and is metered by the spinning metering pump. The supply volume of the metering pump is 10 g / min, the number of rotations is 25 rpm, and then the nylon 6 melt is evenly distributed to the spinning assembly through ...

Abstract

The invention relates to a process for producing a fine-diner super-bright nylon 6 high-orientation fiber. The process is characterized by comprising the following steps of: 1) heating and extruding dried nylon 6 slices to melt the slices into a melt; 2) preserving the heat of the melt and distributing the melt to a spinning component uniformly; 3) allowing the melt in the spinning component to enter a sand cup and adding metal sand into the sand cup; 4) performing high-pressure ejection from a spinneret plate at the bottom of the spinning component to form cellosilk; and 5) performing beam concentration and oil application on the cold-forming tows, passing through a spinning channel, passing through a wound preset network and a wound network, performing high-speed and high-multiplication drafting and then winding into spinning cakes by using a winder to prepare the fiber tows.

Description

technical field [0001] The invention belongs to the preparation and production process of nylon 6 fiber, in particular to a spinning production process of fine denier, large glossy nylon 6 high orientation fiber. Background technique [0002] Nylon fiber is the second largest variety of synthetic fiber in the world, and the third largest variety of synthetic fiber in my country. With the improvement of people's living standards, people's demand for textile raw materials is becoming more and more differentiated, high-end, and personalized. At present, the domestic nylon 6 high orientation fiber technology is concentrated on 44-110 decitex semi-dull products, which cannot meet the requirements of users. The invention provides a production process for producing fine-denier bright nylon 6 high-orientation fibers with a fineness lower than 22 decitex. Contents of the invention [0003] The purpose of the present invention is to provide a fine denier bright nylon 6 highly orien...
