Abstract

The invention discloses a long-term-acting antistatic composite polyester fiber and a preparation method thereof. Carbon black with a specific DBP value is selected to be compounded with single-layer modified graphene according to a specific ratio to form a nano composite structure with good conductivity, and then the nano composite structure is subjected to in-situ copolymerization and melt spinning with terephthalic acid and ethylene glycol so that the composite polyester fiber having a long-term-acting antistatic property can be prepared. Not only can traditional terylene exhibit an excellent antistatic effect by adding a trace amount of graphene and a small amount of carbon black, but also a product has good spinnability, stable performance, low cost, low industrial difficulty and a remarkable practical value.

Description

Technical field [0001] The invention belongs to the fiber field, and particularly relates to a long-lasting antistatic composite polyester fiber and a preparation method thereof. Background technique [0002] In daily life, when two objects of different materials are contacted and then separated, static electricity can occur. This is because one object loses a certain charge and becomes positively charged, while the other object gets negatively charged. These charges are difficult to neutralize easily. It will gradually accumulate to form static electricity. The main ways to form static electricity in daily life are friction, induction and conduction. Static electricity itself is a very common phenomenon, but when static electricity accumulates and is violently released, it is very easy to cause circuit breakdown, information interference, fire, electric shock, etc., which can cause discomfort to the human body and increase the adsorption of dust to the environment. If it becom...
