Problems solved by technology

If both characteristics are available at the same time, it can only be mixed in the subsequent processing, which increases the production process, increases the production cost, and due to the poor control of the mixing uniformity, the effect of the two characteristics at the same time cannot be well highlighted.

Abstract

The invention discloses a large bright polyester fiber and a spinneret used for spinning the same and a preparation method thereof. The cross section of the bright polyester fiber is different cross-shaped, and this structure makes it simultaneously have a flat diamond super Brightness and moisture absorption characteristics, the cross-section of the spinneret holes on the spinneret used is different cross-shaped, and the lengths of the horizontal spinneret holes and the longitudinal spinneret holes of the different cross-shaped spinneret holes are different, which makes the preparation The polyester fiber produced has both the flat diamond super-brightness characteristics of the polyester fiber prepared from the straight spinneret hole and the polyester fiber prepared from the different cross-shaped spinneret holes with the same length as the conventional horizontal spinneret hole and the longitudinal spinneret hole. The ester fiber has the property of moisture absorption and perspiration, and the present invention does not require subsequent plying to make a yarn conforming to dual properties, thereby reducing production procedures and production costs, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of chemical fiber materials, in particular to a bright polyester fiber and a spinneret used for spinning the same and a preparation method thereof. Background technique [0002] my country is a big country of chemical fiber. The production and usage of chemical fiber have reached 60% of the world, of which more than 80% is polyester, which is the general trend of chemical fiber technology development. The brand-new production concept oriented has been deeply rooted in the hearts of the people, and functional and differentiated polyester fibers will become the mainstream of the future market. Currently on the market, the developed functional bright polyester fibers have single functions, poor production stability, and low post-processing efficiency, which cannot meet the market's requirements for multi-functional fiber textiles. [0003] Because the "one" shaped polyester filament has excellent characteristic...
