Nano Nonwovens Are Quietly Changing Your Life.

Nanomaterials are the research focus of international advanced materials. The combination of nanomaterials and nonwovens is also regarded as the most potential application technology in the industry.

After more than 10 years of development, nanomaterials fibre Nonwoven materials and technologies have been transferred from concept research and laboratory to application market. From high-end core materials applications to medical, health, efficient protection, fine filtration, automotive industry, agriculture and other fields of popularization and popularization, and gradually replace the traditional product materials, more and more manufacturers are investing in the application research and market development of nanofibers. In particular, the emergence of functionalized nanofibers has attracted increasing attention.

In terms of medical and health field, nanotechnology can better give non-woven materials antibacterial, hydrophilic, flame-retardant, super flexible and other functional characteristics, better meet the global population of 2/3, women, children, the elderly care and health care, used as surgical gowns, protective clothing, masks, sanitary napkins, diapers for children, etc., significantly improve the comfort of human body. In addition, nano antibacterial modified nonwoven materials have the ability to prevent infection and protect human health. They are health care materials that are very needed in the field of health protection. They can be used as direct contact with human tissue and can be antibacterial, non-toxic and comfortable. The development of the world's nonwoven 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 is deteriorating, and the application of protective and health care products will continue to increase. The demand for health protection products will continue to increase in the next few years. According to the relevant international advisory bodies, the output growth rate will still reach 8.5% in the next 5 years. It can be seen that functional nano modification technology is more widely applied to nonwoven materials, and will have broader market development space in the future.

According to industry experts, nanotechnology has wide application prospects in the nonwovens industry. Different nanomaterials can achieve 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 so on. Material Science 。

Nanofiber melt blown nonwovens composites can be applied to tissue engineering. Based on biopolymer chitosan, chitosan / bone collagen and other raw materials, the application of the functional polymer sub micron nanofiber mesh in tissue engineering is constantly expanding. The machinability of nano composite products and the characteristics of fiber structure make it have the conditions of large-scale production. At present, the application of functional submicron nanofibers in tissue engineering is mainly related to cartilage tissue repair, artificial bone and repair, central nervous system repair and so on.

Electrospun functional nanofiber nets can also be used in tissue engineering and regenerative medicine. In the production of electrospinning, various chemical agents, such as antifungal agents, cell inhibitors and DNA, can be mixed directly with polymer materials to make functional nanofiber network directly. At present, the use of nanofiber sensors in tumor diagnosis has involved nanofiber immunosensors, metal oxide nanofibers gas sensors for lung tumor diagnosis, nanofiber electrochemical biosensors for biomonitoring, and nanofiber fluorescent chemical sensors for histamine detection. The circulating tumor cell flapping device made of nanofiber composite material can also be used in the examination of the important index Biomarker (biomarker) for the early diagnosis of cancer patients.

Melt blown / electrospun fiber composites can be used for bone tissue engineering. The study shows that the three-dimensional microstructure of the melt blown fibers and the good cell compatibility of the spun fibers can be used as a bone cell engineering for improving the bioactivity and the mineralization rate of bone cells. The three dimensional micro - nanofiber scaffolds are chosen to use melted nonwovens and electrospun nanofibrous composite fabrics. Three dimensional micro nanofiber scaffolds were selected to use melt blown nonwovens and electrospun nanofiber composite fabrics.

Due to technical limitations, although there are still some limitations in the application of nanotechnology in the industry, it has always been keen in related research. Many universities and companies have invested heavily in this area, and have made some progress. If you want to know the latest R & D information, the most advanced technology and future development trend of nanofibers in the industrial textiles industry, please pay attention to the China International Industrial Textiles and nonwovens Exhibition (CINTE) held on September 4th ~6 at the New International Expo Center, Shanghai, China.

CINTE is one of the most notable industrial textiles and nonwovens exhibitions in China. The organizers will invite top scientific researchers from home and abroad, as well as nanofiber nonwovens. Material Science Production capacity of enterprises, gathered together for the industry to build barrier free exchanges and business platform, and urge the industry to achieve "intimate contact".
