Non-woven fabrics are cheap, easily biodegradable and recyclable and are now widely used in the market. With the development of the industry, there are more types of non-woven fabrics and the scale of application is also expanding. As people use non-woven fabrics in various industries, they put forward increasingly higher requirements for non-woven fabrics. Non-woven fabric manufacturing factories are also continuously improving the performance of non-woven fabric according to customer demand.
The structure of non-woven fabric 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 a similar fabric, 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 widely.
An important reason why non-woven fabrics are widely used with good breathability. Taking products related to medical work as an example, if the air permeability of non-woven fabric is poor, the tape made of non-woven fabric cannot meet the normal breathing of the skin, which will cause allergic symptoms in the user. Medical tapes such as adhesive tapes have poor air permeability, which can increase the number of microorganisms near the wound and lead to wound infection. The poor air permeability of surgical gowns made of non-woven fabrics will greatly affect their wearing comfort.
Like medical products, the poor air permeability of other non-woven products will also bring many unfavorable reasons for their use. Therefore, strengthening the air permeability test of non-woven fabrics is an important step to ensure that the corresponding products meet the application requirements.
