Non-woven fabrics are now widely used in all walks of life. However, in the production and processing process of non-woven fabrics, enterprises often pay attention to the tensile strength of non-woven fabrics, and their air permeability is often ignored by enterprises, resulting in the production and processing of non-woven fabrics. Cloth has the problem of poor air permeability, so attention needs to be paid to improving the air permeability of non-woven fabrics.
Non-woven fabrics are cheap, easy to decompose, and recyclable, so they have 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. It is usually a single-layer design, which is breathable but has a single structure, resulting in poor non-woven fabric strength, thereby reducing the overall quality of the fabric.
Nowadays, people put forward higher and higher requirements for the use of non-woven fabrics. At present, non-woven fabrics of various materials and processes have appeared on the market. The structure of the non-woven fabric is porous. Relevant studies have shown that the pore size is closely related to the breathable function of the fabric. Generally, the larger the average pore size of similar fabrics, the better the air permeability.
Different types of fabrics have significant differences in pore size and breathability. Due to the difference in fiber raw material, yarn density, fabric structure, fabric warp and weft density and fabric thickness, the air permeability of similar fabrics is also very different. Non-woven fabrics with good air permeability are one of the important reasons for their use.
The above is about the method of improving the air permeability of non-woven fabrics. Non-woven fabrics are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, low in price, and recyclable. Are you excited?
