How non-woven fabrics are anti-static

Static electricity is everywhere in our lives, and its harm should not be underestimated. In industrial production, static electricity generated by fabrics or clothing can cause electric shocks. Although the energy is relatively small, it can also cause interference, such as adsorption of dust, and even lead to serious consequences. For example, in flammable and explosive situations such as petrochemical industry, static sparks It may cause explosion accidents; in the electronics industry, static electricity can cause damage to electronic components, degraded quality, or even scrap; and people’s health is also deeply harmed. According to analysis, static electricity can cause discomfort and irritation when it is severe, or it can cause People’s pigmentation causes cardiovascular disease. Therefore, anti-static is particularly important, and the research on anti-static clothing and other anti-static textiles is of great significance for solving the problem of static electricity in production and life.


Anti-static non-woven fabric is also one of the important anti-static fabrics. Anti-static non-woven fabric can not only effectively prevent static electricity, but also filter dust. At the same time, it is soft, soft and breathable. Mainly used in needle-punched carpets, filter felts, industrial non-woven fabrics, medical supplies, etc.


What are the antistatic treatment methods for non-woven fabrics?


1. Physical method:


1. Opposite charge neutralization method, such as polyester-cotton blended spinning;


2. Reduce the dynamic and static friction coefficient, such as lubricating agent;


3. Increase the dielectric constant between fibers, such as increasing humidity;


4. Charge away method, such as grounding, blended with conductive fiber;


2. Chemical methods:


1. Improve fiber moisture absorption, such as hydrophilic antistatic agent;


2. Improve the ionization of fiber surface, such as ionic antistatic agent;


The role of antistatic finishing:


Improve the moisture absorption capacity of the fiber, improve its electrical conductivity, accelerate the dissipation of charge, and reduce the generation of static electricity.


1. Ionic antistatic agent, ionized and conductive by moisture. The anion-cation type eliminates static electricity by neutralizing the charge. The anionic type reduces static electricity generation by smoothing.


2. Hydrophilic non-ionic antistatic agent The hydrophilic layer relies on the water-absorbing material to improve the water absorption of the fiber, thereby eliminating static electricity.
