Embodiment 1

[0018] A kind of antistatic modified PBT fiber is made of components comprising the following parts by mass:

[0019] 45 parts of terephthalic acid, 43 parts of butanediol, 0.5 parts of tetraethyl titanate, 8 parts of modified graphene, zinc oxide and zirconium oxide with a particle size of 50-100nm in a mass ratio of 1:1. 3 parts of compound, 0.1 part of antioxidant 1010, 0.4 part of triphenyl phosphite.

[0020] Wherein, the modified graphene is prepared as follows: 1) Graphene vulcanization: immerse graphene in concentrated sulfuric acid, heat at a temperature of 140-150°C for 10-12h, take out and wash with distilled water for 3-6 times to obtain vulcanization Graphene; (2) sulfide graphene is dissolved in dehydrated alcohol solvent, and the concentration in the sulfide graphene dehydrated alcohol is 3~5%, and ethanol solvent pH control is 8.5, then adds silane coupling agent KH550, at temperature The reaction is carried out at 35-45° C. for 3-5 hours; (3) centrifugation i...

Abstract

The invention relates to fiber, and in particular to anti-electrostatic modified PBT fiber which is prepared from the following components in parts by mass: 45-50 parts of terephthalic acid, 34-43 parts of butanediol, 0.5-1 part of a catalyst, 8-12 parts of modified graphene, 3-8 parts of a nano metallic compound, 0.1-0.5 part of an antioxidant 1010 and 0.3-0.8 part of a stabilizing agent. The anti-electrostatic modified PBT fiber provided by the invention is good in effective and long-lasting anti-electrostatic property, free of toxin, relatively good in heat resistance and laundering durability, stable in property and applicable to multiple application fields; the anti-electrostatic modified PBT fiber is simple in preparation method, easy to operate, easy to control, low in cost, good in environment-friendliness and applicable to on-scale production.

Description

technical field [0001] The invention relates to fibers, in particular to an 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. Electrostatic hazards often cause heavy loss...
