Abstract

The invention discloses a long-acting antistatic composite nylon fabric and a preparation method thereof. By selecting carbon black with a specific DBP value and compounding it with a single-layer modified graphene in a specific ratio, a new nanocomposite structure is formed, and a fabric with excellent Dispersive conductive additive material. After in-situ copolymerization with caprolactam, melt spinning and weaving, the composite nylon fiber with long-term antistatic properties can be prepared. With the addition of only a small amount of graphene and a small amount of carbon black, the invention can make traditional nylon exhibit excellent antistatic effect, and the product has good spinnability, stable performance, low cost, low industrialization difficulty, and significant practical value.

Description

technical field [0001] The invention belongs to the field of chemical fiber fabrics, in particular to a long-acting antistatic composite nylon fabric and a preparation method thereof. Background technique [0002] In daily life, when two objects of different materials are in contact and then separated, static electricity can be generated. This is because one object loses a certain amount of charge and becomes positively charged, while the other object gains charge and becomes 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 the static electricity is accumulated and released violently, it is very easy to cause circuit breakdown, information interference, fire, electric shock and other phenomena, which can cause discomfort to the human body, i...
