How To Effectively Improve The Breathability Of Non-woven Fabrics

In the process of non-woven fabric production and processing, companies often attach great importance to the tensile strength of non-woven fabrics, but their air permeability is often ignored by companies, resulting in poor air permeability problems in non-woven fabrics produced and processed, so how to improve non-woven fabrics The air permeability of products has now become a concern of many non-woven fabric manufacturers.

Non-woven fabrics are 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, thereby reducing the overall quality of the fabric. 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. The price of non-woven fabrics is very low.

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.

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 meet the normal inhalation of the skin, causing users 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 unfavorable 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 requirements for use.
