What is non-woven fabric?
Non woven fabric refers to a material with a fiber network structure that is not formed through spinning and weaving, but rather through chemical, mechanical, or thermal processing. Due to its lack of weaving or weaving gaps, its surface is smoother, softer, and has good breathability compared to ordinary fabrics such as cotton and linen.
Non woven fabrics are widely used, including but not limited to cleaning products, clothing accessories, medical supplies, furniture, automotive interiors, etc.
Differences in raw materials
The raw materials used in medical non-woven fabrics are more stringent than ordinary non-woven fabrics, and can be carefully screened and treated with advanced techniques. Medical non-woven fabrics usually use polypropylene fibers or polymer fibers, and have undergone special processing. This processing method interweaves fibers together to form a fiber web structure with excellent physical properties, making it more suitable for medical use.
Ordinary non-woven fabrics may use any raw material, including polyester, polypropylene, nylon, etc. However, compared to medical non-woven fabrics, ordinary non-woven fabrics are obviously not as complex and strict in processing.
Different uses
Due to the higher quality of medical non-woven fabrics, their application scope is more limited, mainly used in the field of healthcare. It can be used for medical supplies such as surgical gowns, nurse caps, masks, toilet paper, surgical gowns, and even medical gauze. Due to higher requirements for purity and dryness in some medical applications, medical non-woven fabrics are more suitable.
Ordinary non-woven fabrics, due to their low price, have a wide range of applications and can be used in clothing accessories, daily necessities, cleaning products, packaging materials, and other fields.
Differences in physical properties
The physical properties of medical non-woven fabrics are significantly different from those of ordinary non-woven fabrics. Its physical properties are very stable, and it has high tensile strength and tear resistance. These physical properties make medical non-woven fabrics have stronger load-bearing capacity and durability. It also has good permeability and filtering properties, which make it more suitable for the medical field. For example, the fiber structure of medical masks can provide excellent filtration and breathability.
The physical properties of ordinary non-woven fabrics are usually not as good as medical non-woven fabrics, and their tear and tensile strength are not very strong, nor do they have the same good permeability and filtration performance as medical non-woven fabrics. However, due to the low price of ordinary non-woven fabrics, they are widely used in some daily fields.
Different antibacterial abilities
Since it is a medical non-woven fabric, the primary criterion is its antibacterial ability. Generally, SMMMS three-layer meltblown layer structure is used, while ordinary medical non-woven fabric uses a single-layer meltblown layer structure. Compared with the two, the three-layer structure definitely has stronger antibacterial ability. As for non-medical ordinary non-woven fabrics, they do not have antibacterial properties due to the lack of spray coating.
Since it has antibacterial ability, it also needs corresponding sterilization ability. High quality medical non-woven fabric can be applied to various sterilization methods, including pressure steam, ethylene oxide, and hydrogen peroxide plasma. However, ordinary non-medical non-woven fabrics are not suitable for various sterilization methods.
Quality control varies
Medical non-woven fabrics require certification through relevant product quality control systems, and there are strict standards and requirements for every step of the production process. The main differences between medical non-woven fabric and ordinary non-woven fabric are mainly reflected in these aspects. Both have their own uses and characteristics. In use, as long as the correct choice is made according to the needs, it is sufficient.
Conclusion
In the above analysis, it can be seen that medical non-woven fabric is the same as ordinary non-woven fabric, both of which are non-woven materials but have significant differences in application scope, raw materials, physical properties, and other aspects. Understanding these differences has important guiding significance for selecting specific cleanroom equipment and life applications.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
