Embodiment 1

[0024] A kind of preparation method of the preparation method of antistatic modified PBT fiber, comprises the steps:

[0025] (1) Adding modified graphene, nano-metal compound and butanediol into the reaction kettle, stirring at a temperature of 50-60°C for 0.5-1h;

[0026] (2) Add terephthalic acid and catalyst into the reaction kettle of step (1), raise the temperature of the system to 200-220°C, and react for 2-3h;

[0027] (3) Add antioxidant 1010 and stabilizer, then vacuumize, raise the temperature to 250-280°C, and perform polycondensation reaction for 3-5h. When the viscosity of the polymer is in the range of 0.6-0.9, the reaction is completed to obtain antistatic modification. Non-toxic PBT polyester;

[0028] (4) Pass the antistatic modified PBT polyester obtained in step (3) through a screw-type spinning machine, carry out melt spinning at a temperature of 250-270°C, and after cooling, carry out oiling, 500-600m / min pre-drawing Stretching and stretching at 1000-18...

Abstract

The invention relates to fiber and preparation methods thereof, in particular to a preparation of antistatic modified PBT fiber. The preparation method includes following steps: (1), adding modified graphene, a nano metal compound and butanediol into a reaction kettle; (2), adding terephthalic acid and a catalyst into the reaction kettle of the step (1), and rising temperature of a system to 200-220 DEG C for reaction for 2-3 h; (3), adding an antioxidant and a stabilizer, vacuumizing, rising temperature to 250-280 DEG C, and performing polycondensation to obtain modified PBT polyester; (4), subjecting the modified PBT polyester obtained in the step (3) to fusion spinning and cooling, and treating to obtain the target fiber. The antistatic modified PBT fiber prepared by the method has efficient and lasting antistatic performance, nontoxicity, high heat resistance and washing resistance and stable performance and is suitable for various application fields.

Description

technical field [0001] The invention relates to a fiber preparation method, in particular to a preparation method of antistatic modified PBT fiber. Background technique [0002] Polyester fiber has the characteristics of high strength, good elasticity, strong wrinkle resistance, good abrasion resistance and excellent heat resistance. Therefore, it is an ideal textile material regardless of whether it is widely used in civil and industrial applications. Polyester fiber is currently the largest and most widely used variety of synthetic fibers. Due to its good mechanical properties and tensile properties, it is widely used in clothing, industry, Jiatong transportation, decorative materials and other fields. However, with the expansion of its application fields, it is necessary to meet certain antistatic requirements in some special fields of use, such as military, aviation, transportation, entertainment venues, hospital decoration materials, fire-fighting facilities, etc. Ele...
