Non-woven bags as the 1 kind of environmentally friendly materials made of bags, although it has many advantages, such as light weight, soft, water breathable, non-toxic and non-irritating, antibacterial and chemical resistance and good physical properties, but there are also some shortcomings. The following are the main disadvantages of non-woven bags: relatively poor strength and durability: compared with textile fabrics, non-woven bags have lower strength and durability. This is mainly because non-woven fabrics are directly bonded together by physical methods, rather than interwoven by yarns like textile fabrics. Therefore, the non-woven bag may be damaged or deformed after being subjected to a large external force or used for a long time.
Cleaning restrictions: non-woven bags can not be cleaned like other fabrics. Due to the special structure and material of the non-woven fabric, frequent or improper cleaning may cause its deformation, shrinkage or damage. Therefore, when using non-woven bags, you need to pay attention to the cleaning method and frequency to avoid affecting its service life.
It is easy to crack from the right angle direction: the fibers of the non-woven bag are arranged in a certain direction, which leads to its weak strength in the right angle direction and easy to crack. Therefore, when designing and using non-woven bags, it is necessary to take this into account and avoid applying excessive force in the right angle direction.
In addition, although the non-woven bag itself is non-toxic and harmless, some chemical additives or additives may be used in the production process. If it is not handled properly or inferior materials are selected, it may have a certain impact on the environment. Therefore, when selecting and using non-woven bags, priority should be given to products produced by regular manufacturers, and attention should be paid to their environmental performance and material quality.
In summary, although non-woven bags have many advantages, they also have some disadvantages. In use, it is necessary to select and use according to the actual situation, and pay attention to maintenance and maintenance to extend its service life and reduce the impact on the environment.
