How To Improve The Air Permeability Of Nonwovens?

In the development process of nonwoven fabric production and processing, enterprise management often attaches great importance to tensile strength, but its air permeability is often ignored, resulting in poor air permeability of textile fabrics produced in social production and processing, so how to improve the air permeability of products? Nonwovens are not only cheap but also recyclable, so they are widely used in the market. With the development of industry, there are more and more varieties of textile fabrics, and the scope of application is also expanding. Existing spinning technology is generally single layer, breathable, but single structure. Nowadays, people's requirements for the use of nonwovens are getting higher and higher, which obviously cannot meet the needs of people in the market. The air permeability of non-woven fabrics requires a certain area, a certain pressure (20 mm water column) and the amount of air passing through the spunbond fabric per unit time. Now the unit is mainly liters/square meter. We can use measurement, development and production instruments to measure the air permeability of spunbond fabrics, and through data analysis and testing, we can roughly understand the air permeability of spunbond fabrics.
The non-woven fabric construction method is porous, and the research results of related issues show that the fabric pore size and translation function are closely related to life. In general, the larger the average pore size of similar tissues, the higher the air permeability. Different types of fabrics have marked differences in openness and permeability. The permeability of the same type of fabric also varies greatly due to factors such as raw material fiber, yarn density, fabric, fabric latitude and longitude density analysis, and various fabric thicknesses. Good permeability is one of the important reasons for the wide application of non-woven fabrics. Taking industry-related products as an example, if the permeability of non-woven fabrics is not bad, the tape cannot meet the normal inhalation of the skin and cause symptoms to users. The low permeability of medical tapes such as adhesive tape may lead to the proliferation of microorganisms near the wound and cause serious injury. The protective clothing has low air permeability. As with many products, differences in the permeability of other nonwoven products can lead to many factors that are not conducive to use. Therefore, enhancing the permeability of nonwovens is one of the important measures to ensure that related products meet the requirements of use.
Due to the good permeability of the spun fabric, it is widely used in the processing and production of various medical materials. If the permeability of the spun fabric is low, it is difficult to meet people's needs, so the permeability of the nonwoven fabric must be guaranteed during the production process.
