Static and anti-static fabric

Static electricity is a normal physical phenomena.

In winter, sometimes when the quilt is lifted, my hair becomes frizzy.

There are many factors that influence the generation of static electricity, and many textile manufacturers are trying to eliminate it. As a result, the professional term “anti-static fabric” appeared.

01 Sources and harms of static electricity
The so-called static electricity is a kind of charge in a static state or a non-flowing charge (flowing charge forms a current) .

Causes of static electricity:

1. Frictional electrification, contact separation, and induction electrification .

2. In winter, the weather is relatively dry, and chemical fiber clothing and bedding sets are prone to generate static electricity.

3. The causes of static electricity on the body are roughly divided into: dry skin and lack of oxygen in the body.

Static electricity in fabrics will cause many hazards:

1. The pores will become enlarged and the skin will be damaged. Dryness, erythema, and itchy skin;

2. May cause abnormal heart rate and premature heart beat;

3. Affect people central nervous system, causing people to feel fatigue, irritability, insomnia, and headache.

02 Anti-static fabric

Anti-static fabric is made by mixing conductive fibers during weaving. It may be a yarn or a fabric woven with embedded conductive filaments, or it may be a fabric that has been treated with anti-static properties.

It is common to weave conductive fibers into fabrics based on various fibers to achieve anti-static effects.

Conductive fibers are divided into metallic and non-metallic types. Metal type, such as: stainless copper fiber and other fibers are blended into yarn and then woven;

Non-metal type conductive fiber is generally based on polymer organic fiber. After processing, the specific resistance reaches 102-105Ω·cm. This fiber is blended with other fibers in a certain proportion and structure to achieve an anti-static effect.

Anti-static fabric is also called anti-static fabric, or anti-static fabric for short. The fabric is mixed with conductive fibers. Its electricity dissipation is based on two mechanisms: charge discharge and neutralization.

When grounded, in addition to being neutralized by the corona discharge of the conductive fibers, the static electricity on the fabric can also be discharged to the earth through the conductive fibers. ; When not grounded, electricity is dissipated with the help of weak corona discharge from conductive fibers.

03 Tips for eliminating static electricity in life

1. Clothing softener contains silk protein essence , can form a breathable protective layer on the surface of clothing fibers, reduce friction between fibers and reduce the accumulation of static electricity on the fabric.

2. If you replace the chemical fiber sheets, quilt covers and other bedding materials with soft, smooth cotton textile materials, you can reduce the number of hair, clothes and bedding materials. The friction between them reduces the chance of generating static electricity.

3. The dry and cold climate in winter is also one of the main causes of static electricity. If you place a humidifier in the bedroom, it will not only improve the air quality, but also It can also prevent static electricity.

4. Battery anti-static

Feel the positive and negative terminals of the battery at the same time, or put it in the bag A battery to discharge static electricity through the battery.
