Although non-woven fabrics have many advantages, such as lightweight, softness, and environmental friendliness, they also have some drawbacks and limitations:

Poor strength and durability: Compared to textile fabrics, non-woven fabrics have relatively weaker strength and durability. This makes it perform poorly when subjected to large external forces or long-term use, and is prone to damage or deformation.

Easy to break and wear: Non woven fabrics have poor wear resistance and are prone to breakage or wear during use. This also limits the application of non-woven fabrics in certain fields that require high wear resistance.

Easy to age: Non woven fabrics are prone to aging due to the influence of high temperature and ultraviolet radiation, resulting in a decrease in their physical properties and even being unusable. Therefore, when selecting non-woven materials, it is necessary to consider their usage environment and take corresponding protective measures.

Poor water resistance: The water resistance of non-woven fabrics is not strong enough, and once they encounter rainwater or other liquids, they are prone to wetting or deformation. This limits the application of non-woven fabrics in humid environments.

Relatively poor flame retardancy: The flame retardancy of non-woven fabrics is relatively weak. Although flame retardant treatment can be carried out, it also requires additional production costs and technical investment.

Fiber arrangement leads to easy cracking: The fibers of non-woven fabrics are arranged in a certain direction, which makes it easy to crack from a right angle. This is also a problem that needs to be solved in the production and use of non-woven fabrics.

Environmental issues: Although non-woven fabric itself is an environmentally friendly material, it consumes a large amount of chemicals and energy during the production process, and it is also difficult to dispose of it in a completely environmentally friendly and orderly manner like paper after being discarded. Therefore, in today's increasing awareness of environmental protection, the environmental protection issues of non-woven fabrics also need to be given attention.

In summary, although non-woven fabrics have many advantages, they have some obvious shortcomings and limitations in strength, durability, water resistance, flame retardancy, and other aspects. When selecting non-woven fabrics, it is necessary to fully consider their application scenarios and performance requirements, in order to fully leverage their advantages and avoid the problems caused by their disadvantages.
