How to effectively improve the breathability of non-woven fabrics? In the development of non-woven fabric production and processing, business management often attaches great importance to the tensile strength of non-woven fabrics, but its breathability is often neglected, resulting in social production and processing. Non-woven fabrics have poor air permeability, so how can we improve the air permeability of non-woven products?

Non-woven fabrics are not only cheap, easy to decompose, and recyclable, so they have 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. The existing non-woven fabrics The fabric technology is usually a single-layer design. Although it is breathable but the structure is single, the strength of the non-woven fabric is poor, and then the overall quality of the fabric is reduced. Nowadays, people’s use of non-woven fabrics has also proposed higher and higher non-woven fabrics. Requirements, and the current non-woven fabrics on the market obviously cannot meet people’s needs.

How to improve the breathability of non-woven fabrics? The air permeability of the non-woven fabric requires a certain area, a certain pressure (20mm water column), and the amount of air passing through the non-woven fabric at each unit time. The unit is now mainly L/m2.s. Non-woven fabric air permeability, we can use more professional instruments to measure, develop and produce SG461-III, which can be used to measure the air permeability of non-woven fabrics. After analyzing and testing the data, we can have a general understanding of the air permeability of non-woven fabrics. .

The non-woven fabric construction methods are all porous. The research results of related issues show that the pore size and the air permeability of the fabric can be connected to life. Generally, the larger the average pore size of similar fabrics, the better the air permeability. There are some obvious differences in the pore size and air permeability of different types of fabrics. For the same type of fabric, due to the differences in fiber as the material, yarn density, fabric weave, fabric warp and weft density analysis, and various fabric thicknesses, the fabric air permeability also has A large degree is different.

Good air permeability is one of the important reasons why nonwovens 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 satisfy 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 microorganisms in Propagation 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 application requirements.

It is precisely because non-woven fabrics have good air permeability that they are widely used in the processing and manufacturing of various medical materials. If the non-woven fabric has poor air permeability, it will be difficult to satisfy people's application needs, so we must ensure the air permeability of the non-woven fabric during the production process!
