The terrible static electricity of the fabric is not the fault of chemical fiber!

The cold and dry winter came, and I was often hit by static electricity when I touched others. It was too painful.

I dare not hold hands when I go out with my girlfriend, for fear of too much chemistry.

The static electricity generated by the sweater rubbing against the balloon can change the direction of the water flow

So wool, cashmere, cotton, chemical fiber... What material to wear to solve this problem?

First, let's analyze the causes of static electricity

All matter is made up of atoms, and the basic structure of atoms is protons, neutrons and electrons.

Scientists define protons as positively charged, neutrons as uncharged, and electrons as negatively charged. Under normal conditions, an atom has the same number of protons as the number of electrons, and the positive and negative charges are balanced, so it appears uncharged to the outside world.

However, due to external effects such as friction or in the form of various energies such as kinetic energy, potential energy, heat energy, chemical energy, the positive and negative charges of atoms will be unbalanced. What is called friction in daily life is essentially a process of constant contact and separation. Any two objects of different materials can produce static electricity after contact and then separation, and the common method of generating static electricity is friction electricity.

Generating principle of static electricity

The better the insulation of the material, the more likely it is to generate static electricity. Because air is also composed of atoms, it can be said that static electricity can be generated at any time and anywhere in people's lives. It is almost impossible to eliminate static electricity completely, but there are some measures that can be taken to control static electricity so that it does not cause harm.

Different materials are also different in their ability to "plunder" electrons

This is a graph of the ability of different materials to generate static electricity.

The closer to both sides, the stronger the ability to gain/lose electrons, the easier it is to generate static electricity.

In fabrics, wool, nylon and acrylic are the Kings of generating static electricity.

So wearing these fabrics is helpless to static electricity?

What factors are related to the static electricity generated on the fabric surface?

1. Components of fabric

The more synthetic fiber content, the easier it is to generate static electricity

Pure wool fiber is also a hard hit

The static electricity on the fabric surface can be improved by adding conductive fiber and gold-plated coating.

2. Water content of fiber

In textile materials science, moisture regain is an index to indicate the moisture absorption capacity of the fiber. Expressed as a percentage of the weight of the moisture contained in the material as the weight of the dry material.

Fabrics with strong hygroscopic properties have relatively strong antistatic capacity.

So in summary, we give these fabrics to a qualifying race, which fabrics are easy to generate static electricity? Which are the weak chickens of static electricity.

The "strongest king" in the electrostatic field -- "acrylic" and "Polyester"

Electrostatic industry "the strongest king" is not a false name, a section of electricity to six sections, electricity production fast, strong power. Keep your power up all the time.

Electrostatic field "eternal diamond" - "wool" and other wool

Although the moisture recovery rate of wool is very high, but in the environment of relatively low humidity, wool can be in the electrostatic field, lightning skills in winter sweater, proved that wool in the electrostatic field of the elder status. It's not that the old man doesn't work, but the time hasn't come.

Electrostatic field "stubborn bronze" - "cotton" "hemp"

Stubborn bronze player natural fiber cotton hemp, simple, no electricity. There is no outstanding performance, there is no short board, probably this is the charm of cotton and linen.

The "supreme star flare" in the anti-static field - "Metal fiber", "carbon fiber", "antistatic fiber"

The most important feature of these fibers is that the troops stop them and the electricity guides them.

Acting as the villain of the antistatic world.

Antistatic fibre

The general sweaters on the market now include antistatic fibers. Can effectively reduce the generation of static electricity.

The principle of antistatic fiber is:

1, the formation of a conductive layer on the surface of the material, thereby reducing its surface resistivity, so that the electrostatic charge has been generated quickly leakage.

2, given a certain lubricant on the surface of the material, reduce the coefficient of friction, thereby inhibiting and reducing the generation of electrostatic charge.

3. Construct a transmission path so that charged particles can come into contact.

In addition to the antistatic fiber can effectively reduce the generation of static electricity, we can also add anti-static laundry detergent/spray, which has the addition of antistatic agents, the specific varieties of many principles are also many, some add negative/cation, neutralizing static electricity, and some increase the hydrophilic groups on the surface of the fabric, so as to achieve electricity conduction.
