Embodiment 1

[0025] A preparation process of polyester superfine fiber, said polyester superfine fiber is 30D polyester superfine fiber, and its preparation process comprises the following steps:.

[0026] (100) Melting: Polyester chips are used as raw materials and melted by a screw to form spinning stock solution;

[0027] (200) Metering and spinning: adjust the flow rate of the melted spinning stock solution through a metering pump, and then spray it out from the spinneret for spinning and forming to obtain fiber tow; the spinneret is a 10-hole spinneret ; A slow cooler is installed below the spinneret, the spinneret is slowly cooled by the slow cooler, the temperature of the slow cooler is 320 °, and the plate surface temperature of the spinneret is controlled at 292 ° , to ensure stable spinning, to avoid the skin-core structure of the fiber tow due to rapid cooling, so that the fiber will have wool and broken ends during the subsequent stretching and setting process, and the dyeing p...

Embodiment 3

[0043] A preparation process of polyester superfine fiber, said polyester superfine fiber is 30D polyester superfine fiber, and its preparation process comprises the following steps:.

[0044] (100) Melting: Polyester chips are used as raw materials and melted by a screw to form spinning stock solution;

[0045] (200) Metering and spinning: adjust the flow rate of the melted spinning stock solution through a metering pump, and then spray it out from the spinneret for spinning and forming to obtain fiber tow; the spinneret is a 10-hole spinneret ; A slow cooler is installed below the spinneret, and the spinneret is slowly cooled by the slow cooler. The temperature of the slow cooler is 330 °, and the plate surface temperature of the spinneret is controlled at 295 ° , to ensure stable spinning, to avoid the skin-core structure of the fiber tow due to rapid cooling, so that the fiber will have wool and broken ends during the subsequent stretching and setting process, and the dyei...

Abstract

The invention discloses a preparation process of dacron superfine fiber. The process comprises the following steps: (100) fusion; (200) metering and spinning, wherein the flow of a spinning solution subjected to the fusion is adjusted through a metering pump, and then a spinneret plate is used for erupting, spinning and forming to prepare fiber tows; a slow cooler is installed below the spinneretplate, and the slow cooler is used for slowly cooling the spinneret plate; (300) cooling and oiling; (400) pre-netting; (500) stretching and sizing; (600) main network; and (700) winding. By the mode,the process can guarantee the stable operation of spinning, the problems that broken filaments and broken ends appear easily in the fiber stretching and sizing process and dyeing performance is relatively poor are solved, and the products can be stably produced, and are high in level dyeing rate and excellent in quality.

Description

technical field [0001] The invention relates to the field of nylon preparation, in particular to a preparation process of polyester superfine fiber. Background technique [0002] With the rapid development of the textile industry, more patterns of fabrics emerge in an endless stream, and corresponding types of fiber raw materials are derived thereupon. Due to the fineness of the single filament, the stiffness of the microfiber is reduced, and the fabric made is extremely soft. At the same time, the layered structure of the filament can be increased, the specific surface area and capillary effect can be increased, and the reflected light inside the fiber is finely distributed on the surface. It has a silky elegant luster and good moisture absorption and dehumidification properties. Microfiber has many advantages such as softness, anti-pilling, easy care, good bristle standability, high density and breathability, etc., which meets the requirements of consumers to a certain ex...
