Non-woven fabrics are cheap, easy to decompose, and recyclable, and are now 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 expanding. Because people use non-woven fabrics in various industries in various industries, they have put forward increasingly higher requirements for non-woven fabrics. Non-woven fabric manufacturing factories are also constantly improving the performance of non-woven fabrics according to customer needs.
The structure of non-woven fabrics is porous. Relevant studies have shown that pore size is closely related to the breathability of fabrics. Generally, the larger the average pore size of similar fabrics, the better the breathability. Different types of fabrics have significant differences in pore size and breathability. Due to differences in fiber raw materials, yarn density, fabric structure, fabric warp and weft density and fabric thickness, the breathability of similar fabrics also varies greatly.
One of the important reasons why non-woven fabrics with good breathability are widely used. Taking products related to medical work as an example, if the air permeability of non-woven fabrics is poor, the tape made of non-woven fabrics cannot meet the normal breathability of the skin, which will cause allergic symptoms in the user. Medical tapes such as adhesive tape have poor air permeability, which can cause microorganisms to multiply near the wound and lead to wound infection. The poor air permeability of surgical gowns made of non-woven fabrics will greatly affect the comfort of wearing them. Like medical products, the poor air permeability of other non-woven products will also bring many adverse 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.
