Reasons for the excellent waterproof performance of non-woven fabric

The excellent waterproof performance of non-woven fabric is mainly attributed to its unique structure and material characteristics. As a material made from fibrous materials processed through special techniques, non-woven fabric exhibits distinct advantages in structure, providing it with a certain level of moisture resistance.

The flexible and orderly arrangement of fibers in non-woven fabric results in small inter-fiber gaps, making it difficult for water to penetrate. Additionally, the fiber material of non-woven fabric itself possesses certain moisture absorption and desorption capabilities, enabling quick expulsion of surface moisture to maintain internal dryness.

However, native non-woven fabric still has certain limitations in waterproof performance. Due to its relatively loose structure and irregular fiber arrangement, non-woven fabric may experience penetration when subjected to large amounts of water or prolonged immersion.

To overcome this limitation, specific processing techniques are employed to enhance the waterproof performance of non-woven fabric. Coating with waterproof layers is a common and effective method. By applying a special waterproof coating onto the surface of non-woven fabric, water penetration can be effectively blocked, enhancing its waterproof ability. These coatings typically exhibit excellent water resistance and durability, maintaining waterproof effectiveness over time.

Moreover, non-woven fabric can serve as a reinforcing layer for waterproof materials when combined with other waterproof materials. By laminating non-woven fabric with waterproof materials, a composite material with stronger waterproof performance can be formed. This composite material not only boasts excellent waterproof properties but also possesses good flexibility and durability, suitable for various complex waterproofing projects.

In practical applications, non-woven daily protective products is widely used across various fields due to its outstanding waterproof performance. In construction engineering, non-woven fabric is commonly employed as a waterproof layer for structures such as culverts, tunnels, and dams, effectively preventing water penetration and safeguarding structural stability and safety.

Furthermore, in daily life, non-woven fabric plays a significant role in waterproofing. Items such as raincoats and camping tents often utilize non-woven fabric, effectively resisting rainwater intrusion and maintaining interior dryness and comfort.
