With the development of industry, there are more and more types of non-woven fabrics, and the scope of application is also expanding. Non-woven fabrics are cheap, easy to decompose, and recyclable, so they have a wide range of applications in the market. The existing non-woven fabric technology is usually a single-layer design. Although it is breathable, the structure is single, resulting in poor strength of the non-woven fabric, thereby reducing the overall quality of the fabric. Increasingly high requirements, and the current non-woven fabrics on the market obviously cannot meet people's needs. The price of non-woven fabrics is very low.
The good air permeability of non-woven fabrics is one of the important reasons why non-woven fabrics are widely used. Taking related products in the medical industry as an example, if the non-woven fabric has poor air permeability, the tape made of tape cannot meet the normal inhalation of the skin, causing the user to have allergic symptoms. However, the poor air permeability of tape and other medical tapes can lead to microbial inhalation. Breeding near the wound, leading to wound infection, poor air permeability of protective clothing will greatly affect the comfort of wearing. Like medical products, the poor air permeability of other non-woven fabrics will also bring many disadvantages 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 requirements for use.
The structure of the non-woven fabric is porous. Relevant studies have shown that the size of the pore size is closely related to the air permeability of the fabric. Generally, the larger the average pore size of similar fabrics, the better the air permeability. Different types of fabrics have obvious differences in pore size and air permeability. Due to the difference in fiber raw materials, yarn density, fabric weave, fabric warp and weft density and fabric thickness, the air permeability of similar fabrics is also very different.
