Problems solved by technology

At present, the number of manufacturers using this method to produce full-dull fibers is gradually increasing. However, the overall market demand for full-dull chips is not large, and there is a contradiction between the conventional production capacity of large-capacity polyester production equipment, which makes it difficult to achieve long-term continuous production of full-dull chips. Production, the device needs to change production frequently, which not only increases the various production costs of full-dull chips, but also has inherent quality differences in each batch of full-dull chips, which causes difficulties for spinning mills
In addition, this method also has a disadvantage, that is, the content of the matting agent TiO2 in the full matting slice is not easy to be flexibly adjusted according to user needs

Embodiment 1

[0015] The sheath-core composite spinning assembly is used for melt spinning. The core components are all made of semi-dull PET chips with a TiO2 content of 0.2%-0.5%, and 97.5% of the skin components are also the above-mentioned semi-dull PET chips. 2.5% of the total is the full matt masterbatch imported from a major Japanese ink company containing TiO250%, and the total amount of cortex components accounts for 30% of all raw material slices. The spinning process is: chip conveying→drying→masterbatch adding device metering and mixing→screw extruder→melt filter→spinning box→metering pump→spinneret assembly→side blowing→cooling→winding. The spinning temperature is controlled at 290-295° C., and the spinning speed is 3000-4000 m / min to obtain full-dull POY winding yarn. The POY winding wire is further processed into DTY through double-zone thermal stretching, with a draw ratio of 1.58-1.72. The temperature of the deformation heating box is controlled at 190-220°C, the temperatur...

Embodiment 2

[0017] Same as Example 1, wherein 5.0% of the full matt masterbatch is added to the skin layer component.

Embodiment 3

[0019] Same as Example 1, wherein the total amount of cortex components accounts for 20% of all raw material slices.

Abstract

The invention provides a production method of a full-dull polyester fiber. According to the production method, common semi-dull polyester chips are taken as a main producing material, and melt spinning is performed by adding full-dull master batch so as to produce the full-dull polyester fiber. A composite spinning component is used in the melt spinning process, correspondingly, the material chips are divided into two or more components, the full-dull master batch is added into one component in the feeding process, and the content of titanium dioxide particles accounts for 1wt%-5wt% of the total weight parts of the fiber.

Description

technical field [0001] The invention relates to polyester fibers, in particular to a production method of full-dull polyester fibers, and belongs to the technical field of synthetic fiber production. Background technique [0002] Clothes made of traditional ordinary semi-dull polyester fibers are difficult to apply to casual clothing and high-end clothing because of their obvious surface gloss and strong waxy texture. As for the full-dull polyester fiber, it is physically modified on the basis of ordinary polyester fiber, and a high content of matting agent is added to make the fiber and fabric have the characteristics of soft luster, high drapability, and strong shielding performance. With the development of the trend of life towards leisure, comfort and casualness, full-dull polyester fiber has attracted more attention from insiders, and its production method has been further researched and developed. [0003] According to domestic and foreign literature reports: Shaoxing...
