Anti static spunbond non-woven fabric

With the development of society, the use of non-woven fabrics is becoming increasingly widespread. During the use of non-woven fabric products, static electricity is often generated due to friction, which is extremely harmful in certain situations. Therefore, for certain products with special electrostatic performance requirements, static electricity performance testing must be carried out. If static electricity is generated during medical surgery, high-end surgical gowns, protective clothing, and wraps need to be treated with anti-static agents.

There are three main methods for electrostatic performance testing: electric green discharge electrostatic testing, frictional electrostatic performance testing, and electrostatic adsorption testing.

The electrostatic characteristics of non-woven fabrics

Non woven fabric is a type of non-woven fiber material, which is composed of multiple fibers combined into a mesh structure through methods such as spunbond and melt blown. Due to the rough surface and strong internal porosity of non-woven materials, static electricity is easily generated during friction, shuttle, and electric absorption. In response to this characteristic, non-woven fabric manufacturers usually need to take some anti-static measures during the production process.

Application of anti-static spunbond non-woven fabric

Anti static non-woven fabrics are increasingly widely used in industries, agriculture, household use, clothing, and other fields. However, the requirements for anti-static effects vary in different fields. For example, in high-end industries such as electronics and pharmaceuticals, the requirements for anti-static non-woven fabrics are particularly high, while in ordinary clothing, the requirements are average.In order to ensure the quality and safety of spunbond non-woven fabric products, a series of anti-static measures must be taken, such as adding anti-static agents, processing, etc. Anti static non-woven fabrics are mainly used in high-tech industries, such as electronics, semiconductors, etc., which can effectively improve the quality and safety of products.

Anti static methods

To ensure the anti-static performance of non-woven products, the following methods are generally adopted:

1. Use anti-static materials

When producing non-woven fabrics, anti-static agents such as anionic surfactants can be added. These materials can form a protective film on the surface of fibers, effectively slowing down or eliminating static electricity. Meanwhile, during the production process, environmental parameters such as temperature and humidity can also be controlled to a certain extent to reduce the generation of static electricity.

2. Handling

Non woven fabric products are also prone to generating static electricity during packaging, handling, and other processes. For this, the product can be processed after production is completed. A common method is to spray anti-static agents on its surface to form a protective film and reduce static electricity.

3. Processing

When processing non-woven fabric products, some measures can be taken, such as adding an electrostatic eliminator to the processing machine, soaking in water before processing, etc.
