How to effectively improve the breathability of sms non-woven fabrics? In the production and processing of non-woven fabrics, companies often attach great importance to the tensile strength of sms non-woven fabrics, but companies often ignore their air permeability, which leads to problems in the production and processing of non-woven fabrics. Due to poor air permeability, how to improve the air permeability of sms non-woven fabric products has now become a concern of many non-woven fabric manufacturers.

SMS non-woven fabric is not only cheap, easy to decompose, but also recyclable, so it has a wide range of applications in the market. With the development of industry, there are more and more types of non-woven fabrics, and the scope of application is also expanding. Now, people have many higher requirements for the use of sms non-woven fabrics, and the sms non-woven fabrics currently on the market obviously cannot meet people's needs.

So, how to effectively improve the breathability of sms non-woven fabrics? The air permeability of non-woven fabric requires the amount of air passing through the non-woven fabric per unit time under a certain area and a certain pressure (20mm water column). The current unit is mainly L/m2·s. The air permeability of sms non-woven fabric can be measured with the help of more professional instruments, so that we have a general understanding of its air permeability.

Good air permeability is one of the important reasons why sms non-woven fabrics are widely used. Taking related products in the medical industry as an example, if non-woven fabrics have poor air permeability, plasters made with them cannot meet the normal needs of the skin. Breathing can cause allergic symptoms in users; the poor air permeability of band-aids and other medical tapes can cause microbes near the wound to multiply and cause wound infection. Poor air permeability of protective clothing will affect wearing comfort. Similar to medical products, the poor air permeability of other sms non-woven products will also bring many disadvantages to their use. Therefore, strengthening the test of the breathability of sms non-woven fabrics is one of the important measures to ensure that the relevant products produced by them meet the requirements of use.

It is precisely because sms non-woven fabrics have good air permeability, so they are widely used in the processing and production of various medical materials. If the air permeability of sms non-woven fabrics is poor, it will be difficult to meet people's needs, and the demand for non-woven fabrics will be greatly reduced. Therefore, the quality of sms non-woven fabrics must be guaranteed during the production process.
