Nano-nonwovens are quietly changing your life

Nanomaterials is the focus of research on international advanced materials. The combination of nanomaterials and non-woven processes has also been recognized by the industry as the most promising application technology.

After more than 10 years of development, nanofiber nonwoven materials and technologies have moved from concept research and development, laboratories to application markets, from high-end core materials applications to medical, high-efficiency protection, fine filtration, automotive industry, agriculture and other popularization and generalization fields. Transfer and gradually replace traditional product materials, more and more manufacturers are investing in nanofiber application research and market development. In particular, the emergence of functionalized nanofibers has attracted increasing attention.

In the field of health care, nanotechnology can better impart non-bacterial, hydrophilic, flame-retardant and super-soft functional properties to non-woven materials, and better meet the needs of women, children and the elderly who account for 2/3 of the world's total population. Nursing care, used as surgical gowns, protective clothing, masks , women's sanitary napkins, baby diapers, etc., significantly improve the comfort of the human body. For example, the nano antibacterial modified non-woven material has the ability to prevent disease transmission and protect human health, and is a medical and health care material that is very much needed in the field of health protection. It can be used as an antibacterial, non-toxic and comfortable medical treatment in direct contact with human tissues. Hygiene products. The development of the world non-woven industry has shown strong growth momentum. Due to the continuous improvement of people's living standards, China's family planning policy has been liberalized, the global health environment has deteriorated, and epidemic diseases have been globalized. The application of protective health products will increase. It is expected that demand will continue to increase in the next few years. According to the prediction of international relevant consulting agencies, its output growth rate will still reach 8.5% in the next five years. It can be seen that functional nano-modification technology is more widely used in non-woven materials, and there will be a broader market development space in the future.

In the opinion of industry experts, nanotechnology has a wide application prospect in the non-woven industry. Different nano materials can realize different functions. For example, nano-modified fibers can be used for photocatalysis, antibacterial and antistatic, and nano -nonwovens can be used to prepare filter masks. , carbon nanotubes and other materials.

Nanofiber meltblown nonwoven composites can be used in tissue engineering. Based on the biopolymer chitosan, chitosan/collagen and other raw materials, the application of the modified polymer submicron-nanofiber mesh material in tissue engineering is expanding with the modified melt-blown device. The processability and fiber structure characteristics of nano-scale composite products make it suitable for large-scale production. At this stage, the application of functional submicron-nanofibers in tissue engineering mainly involves cartilage tissue repair, artificial bone and repair, and central nervous system repair.

Electrospun functional nanowebs are also used in tissue engineering and regenerative medicine. Functional nanowebs can be directly prepared by adding various chemical agents such as antifungal agents, cytostatics, and DNA to the electrospinning production to be mixed with the polymer raw materials. Currently, the use of nanofiber sensors in tumor diagnosis has involved nanofiber immunosensors, metal oxide nanofiber gas sensors for lung tumor diagnosis, nanofiber electrochemical biosensors for biomonitoring, and for "groups". Amine" detection of nanofiber fluorescent chemical sensors and the like. The circulating tumor cell collection device prepared by the nanofiber composite material can also be used in the examination of the important indicator "Biomarker" for early diagnosis of tumor patients.

Meltblown/electrospun fiber composites are used in bone tissue engineering. Studies have shown that the multi-component fiber composites produced by the melt-blown fibers have good cell compatibility with electrospun fibers, and the multi-component fiber composites are used for bone cell engineering, which can significantly improve biological activity and bone cell mineralization. Rate. The three-dimensional micro-nanofiber scaffolds were selected using a meltblown nonwoven fabric and an electrospun nanofiber web composite fabric. The three-dimensional micro-nanofiber scaffolds were selected using a meltblown nonwoven fabric and an electrospun nanofiber web composite fabric.

Due to technical limitations, although there are certain limitations in the application of nanotechnology in the industry, it has always been keen on relevant scientific research. Now many universities and companies have invested heavily in this and made some progress. If you want to know the latest research and development information, the most advanced technology, and the future development trend of nanofiber in the industrial textile industry, please pay attention to China International Industrial Textiles held at the Shanghai New International Expo Center from September 4th to 6th. And nonwovens exhibition (CINTE).

As one of the most watched industrial textiles and nonwovens exhibitions in China, CINTE will invite top researchers from domestic and foreign high-end institutions and companies with nanofiber nonwovens production capacity to gather together. The industry has set up a platform for barrier-free communication and trade, and urged industry professionals to achieve "close contact."
