What Is Anti-Static Fabric?

Anti-static fabric, also known as anti-static cloth, is a type of material that prevents the buildup of static electricity.

Its anti-static properties are based on two mechanisms: charge dissipation and neutralization.

When grounded, the static electricity on the fabric is neutralized through the corona discharge of conductive fibers, and any remaining static electricity can be dissipated to the ground through the conductive fibers.

If not grounded, the weak corona discharge from the conductive fibers can still dissipate the static electricity.

Effects of Wearing Performance on Clothing.

The static electricity generated by clothing of different materials can cause the clothes to tangle with each other, making it inconvenient to wear. When the clothing and skin have opposite charges, they can adhere to each other, causing difficulties in walking.

Causes Accidental Accidents

Wearing synthetic clothes can generate a large amount of static electricity, which can accumulate on the surface of the clothes. The accumulated static charge can produce sparks by breaking down the air gap, and the energy of the sparks is enough to ignite the flammable and explosive gases around, causing fires or even explosions.

Affects Human Health

The mechanism of the effect of static electricity on the human body is not yet clear. Some people believe that static electricity can cause an increase in blood pressure; others believe that static electricity can cause calcium loss in the blood; and still others believe that static electricity can cause skin allergies, among other effects.

Impact on the Quality of Textile Products.

During the process of opening loose fibers, static electricity causes the loose fibers to adhere to the machine frame, pipelines, and other places, resulting in uneven thickness of the output fiber layer, and also causing difficulties in production due to entanglement, compression, and rolling.

Principle of Anti-Static Textile Materials:

There are generally two ways in which static electricity is generated:

1. Static electricity generated by contact.

2.Static electricity generated by induction.

Contact-generated static electricity is mainly due to the movement of charges. When two objects come into contact and rub against each other, one object's surface begins to accumulate positive charges while the other object's surface becomes negatively charged, resulting in static electricity.

Static electricity generated by induction occurs when a conductive material is near a conductor or insulator. The conductor or insulator side closest to the conductive material will begin to accumulate charges. After a long period of induction, the positive and negative charges of the conductor or insulator will be completely separated, resulting in static electricity.

Both of these cases can be referred to as the charge transfer effect. Therefore, anti-static refers to the ability of anti-static fabric to minimize the charge transfer effect, prevent the accumulation of static electricity, reduce friction or contact with the product, and achieve the goal of anti-static. The following are three commonly used methods:

Antistatic Methods for Textiles

The methods for anti-static treatment of textiles are mainly to increase the conductivity of fibers and to improve the humidity of the surrounding environment. The most basic and important method is to reduce the electrical resistance of fibers and increase their conductivity. There are three main methods for anti-static treatment of textiles:

Treating fabrics with anti-static agents;
Modifying the fibers by grafting hydrophilic groups onto them, blending or interweaving with hydrophilic fibers;Blending or interweaving with conductive fibers.

The mechanisms of the first two methods are to increase the fabric's moisture regain, reduce its insulation, and accelerate the leakage of static electricity. Therefore, their effects may not be durable or significant in dry environments or after repeated washing.

The third method can solve the problem of static electricity in textiles permanently and efficiently, and can be applied to special functional clothing such as anti-static workwear.

1. External Anti-static Method

The method of attaching external anti-static agents to the surface of fibers is called surface treatment, which can be divided into temporary and durable anti-static treatment methods.

(1) Temporary anti-static treatment. Generally, external spraying, impregnation, and coating methods are used to prevent static interference during fiber manufacturing and processing.

(2) Durable anti-static treatment. Durable anti-static treatment is achieved by attracting ions of opposite electrical charge to the surface of fibers, through crosslinking via heat treatment, or by adhering to a resin carrier, resulting in a certain level of durability, wash resistance, friction resistance, and other properties.

2. Internal Anti-static Method

The following three methods are used to incorporate anti-static agents into the fibers:

(1) Modify the fiber polymer before spinning. Usually, hydrophilic compounds are copolymerized with fiber monomers before spinning.

(2) Use a blend spinning method to blend the polymer with anti-static agents, or use a composite spinning method.

(3) Coat the fiber surface with a conductive metal or carbon black (which actually belongs to surface treatment), or use composite spinning to produce anti-static fibers containing carbon black.

 

Fabrics treated with anti-static agents can be widely used for various purposes, such as underwear and outerwear. However, the performance of underwear fabrics varies, so the post-treatment of the fabric should be determined according to its intended use. Through practice, the following requirements are placed on anti-static agents used in fabric treatment:

(1) Good anti-static effect, low dosage, not affected by other auxiliaries, and can still have a good anti-static effect under low humidity conditions.

(2) Does not reduce the color fastness or change the color of the fabric.

(3) Does not significantly reduce the physical properties of the fabric or alter its handfeel or style.

(4) Has no adverse effects on processing equipment, such as rust.

(5) Odorless and non-irritating to the skin.

(6) Has good durability and heat resistance suitable for the intended use of the fabric.

Test Methods for Static Electricity Properties of Textiles

The testing methods for the static electricity properties of fibers or fabrics can be roughly divided into two categories: qualitative analysis and quantitative analysis.

Qualitative analysis includes observing the presence or absence of discharge sparks, electric shocks, discharge sound, and attraction (dust adhesion, soiling, and entanglement with the body).

Quantitative analysis includes measuring the fiber resistance, static potential, and half-life, or measuring the friction-induced static voltage, half-life, charge amount, and attenuation of fabrics, and also determining the resistivity and adhesion.
