How to effectively improve the air permeability of non-woven fabrics? In the process of non-woven production and processing, enterprise management often pays more attention to the tensile strength of non-woven fabrics, but its air permeability is often neglected, resulting in social production The processed non-woven fabric has poor air permeability, so how can we improve the air permeability of non-woven products?

Non-woven fabrics are not only cheap, easy to differentiate, and recyclable, so they are widely used in the market. With the development of industry, there are more and more types of non-woven fabrics, and the scale of application is also In expansion, the existing non-woven technology is usually a single-layer design. Although it is breathable, the structure is single, resulting in poor non-woven strength, thereby reducing the overall quality of the fabric. Non-woven fabrics have put forward higher and higher requirements, and the non-woven fabrics currently on the market obviously cannot meet people's needs.

How to effectively improve the air permeability of non-woven fabrics? The air permeability of non-woven fabrics requires a certain area, a certain pressure (20mm water column), and the amount of air passing through the non-woven fabric manufacturer at each unit time. For the air permeability of non-woven fabrics, we can use professional instruments to measure, develop and produce SG461-III, which can be used to measure the air permeability of non-woven fabrics. After data analysis and testing, we can get a general understanding of the air permeability of non-woven fabrics.

The construction methods of non-woven fabrics are all porous. The results of the research on related issues show that the pore size and the air permeability of the fabric can be closely related. Generally, the larger the uniform pore size of similar fabrics, the better the air permeability. the better. There are some significant differences in the pore size and air permeability of different types of fabrics. For the same type of fabric, the air permeability of the fabric is different due to the difference in fiber as raw material, yarn density, fabric structure, fabric warp and weft density analysis, and various fabric thicknesses. There is also a big difference.

Good air permeability is one of the important reasons why nonwovens are widely used. Taking the related products of the medical profession as an example, if the air permeability of the non-woven fabric is poor, the adhesive tape made of tape cannot satisfy the normal inhalation of the skin, which will cause the user to experience allergic symptoms. Wounds multiply nearby, leading to wound infection, and poor ventilation of protective clothing will greatly affect the comfort of wearing. As with medical products, the poor air permeability of other non-woven products will bring many unfavorable factors to their use. Therefore, strengthening the air permeability test of non-woven fabrics is one of the important measures to ensure that related products meet the application requirements.
