A kind of preparation method of functional polyester fiber

Abstract

The invention discloses a method for preparing functional polyester fibers. The preparation device includes a casing, the bottom of the liquid inlet cylinder is connected with a liquid inlet mechanism, and the liquid inlet mechanism is installed on the casing. A stirring mechanism is installed on the casing, and a mixing mechanism is connected to the bottom of the stirring mechanism, and the mixing mechanism is arranged inside the casing. The liquid inlet mechanism can be used to facilitate the sealing of the liquid inlet cylinder when the liquid is fed, so as to achieve a good sealing effect, which is conducive to improving the output and efficiency in the production process. The agitation mechanism can It is convenient for mixing and reacting organic dibasic acid and dibasic alcohol, and the viscous polyester fiber at the bottom can be mixed and stirred by the provided mixing mechanism to facilitate its discharge. When the preparation method is used to prepare the polyester fiber, the performance of the polyester fiber can be improved, the functional strength thereof can be improved, and the production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of polyester fiber preparation, and in particular relates to a preparation method of functional polyester fiber. Background technique [0002] Polyester fiber, referred to as PET fiber, belongs to polymer compounds. It is the largest variety of synthetic fiber at present. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is strong and durable, anti-wrinkle and non-ironing, and non-sticky. However, during the production process of polyester fiber, the airtightness will be weak. Since more air enters during the heating process, which will affect the polycondensation reaction, it is necessary to prevent or eliminate the entry of air as much as possible during the liquid intake process. When there is air After entering the preparation equipment, the yield of polyester fiber will be reduced. Contents of t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for preparing functional polyester fibers, which can solve the problem of poor sealing performance of existing polyester fibers during the manufacturing process, as more air enters during the heating process, which affects polycondensation In the reaction, it is necessary to avoid or prevent the entry of air as much as possible during the process of liquid entry. When air enters the preparation equipment, it will reduce the yield of polyester fibers.
