Embodiment 1

[0019] Such as figure 1 Shown, a kind of preparation method of polymerization micro-modified bright polyester fiber, successive steps are as follows:

[0020] The first step, the preparation of nano-barium sulfate micro-modified polyester melt: phthalic acid and ethylene glycol respectively enter the slurry preparation tank 3 through the phthalic acid delivery pipeline 1 and No. 1 ethylene glycol delivery pipeline 2, and The slurry is evenly mixed under the action of the stirring motor 4, and simultaneously nano-barium sulfate and ethylene glycol enter the nano-barium sulfate suspension preparation tank 7 through the nano-barium sulfate delivery pipeline 5 and No. 2 ethylene glycol delivery pipeline 6 respectively; During the conveying process, the nano-barium sulfate suspension is mixed with the slurry, and then enters the slurry feeding tank 8, and the slurry passes through the esterification reactor 9, the metering injection pump 10, the catalyst feeding device 11, the prec...

Embodiment 2

[0028] Such as figure 1 Shown, a kind of preparation method of polymerization micro-modified bright polyester fiber, successive steps are as follows:

[0029] The first step, the preparation of nano-barium sulfate micro-modified polyester melt: the nano-barium sulfate and ethylene glycol are respectively passed through the nano-barium sulfate delivery pipeline 5 and the second ethylene glycol delivery pipeline 6 into the nano-barium sulfate suspension preparation tank 7. Prepare a nano-barium sulfate suspension; phthalic acid and ethylene glycol enter the slurry preparation tank 3 through the phthalic acid delivery pipeline 1 and No. 1 ethylene glycol delivery pipeline 2 respectively, and make the slurry under the action of the stirring motor 4 The material is mixed evenly, and then enters the slurry feeding tank 8, and the prepolymer obtained after the slurry passes through the esterification reactor 9 and the metering injection pump 10 is mixed with the nano-barium sulfate s...

Embodiment 3

[0038]The difference from Example 2 is that the particle size of the nano-barium sulfate is 0.55-0.66 μm, and the breaking strength of the finished silk is 5.24 cN / dtex after testing.

Abstract

The invention discloses a method for producing chemical fibers, in particular discloses a preparation method of super bright polyester fibers, and aims to provide a preparation method of polymerized micro-amount modified super bright polyester fibers which are bright in luster, excellent in performance and good in abrasion resistance. By adopting the preparation method, a woven fabric has good hand feeling, excellent moisture penetrability and air permeability, bright appearance and excellent luster, and can be used for scarves, pajamas, sweaters, woolen sweaters, shell fabrics needing a flash effect and the like.

Description

technical field [0001] The invention relates to a method for producing chemical fibers, in particular to a method for preparing bright polyester fibers. Background technique [0002] Bright polyester fiber has the characteristics of high strength and bright color. The fabric made of it is beautiful, has good air permeability, and has special visual effects, and is very popular among people. At present, the bright polyester fiber on the market mainly obtains bright luster by changing the cross-sectional shape of the fiber, such as triangle, trefoil, etc. Among them, the fiber with a triangular cross-section has a refraction effect similar to a prism, through the comprehensive effect of light separation, reflection and interference. , so that the fiber and its fabric have the characteristics of bright luster, strong reflection and good flash, and can be applied to the fields of stage costumes, home decoration fabrics and fashion fabrics. However, special-shaped fibers are eas...
