The Introduction Of New Technology Brings A New Hole In The Textile Industry.

Generally speaking, the diameter of 100-500 nanofibers is regarded as nanofibers.

Strictly speaking, nanofibers are nonwoven fabrics of sub micron grade fibers, and can be made into nanofiber web materials by electronic spinning based on end use, including biodegradable polymers.

Because of the advantages of large surface area, flexibility, permeability, micro pore structure, light weight, high Young modulus and good functionality, nanoscale fiber products have been successfully applied in a large number of applications.

Such as filters, chemical resistant fabric lining, tissue support and some advanced engineering applications.

The Natick military center of the United States collaborates with government, industry and institutions to explore the practical applications of nanofibers and nanoparticles in protective clothing, such as thermoplastic elastomer polyurethane electronic spinning fabric, which has good performance. It has high elasticity, and does not need further processing or processing.

The current test and development are focused on functional melt blown and electronic spinning, mixed with nanoscale aluminum and titanium materials, and other methods to add reactive compounds to fabric for self decontamination.

Donaldson has been engaged in biomedical research in the field of nanofiber network for over 20 years.

In 1981, UltraWeb nanofiber filtration equipment was industrialized and expanded to new applications, such as nanofiber cell culture materials and barrier clothing.

In 2002, Donaldson also set up a new team to develop three-dimensional cell culture media to simulate in vivo extracellular matrix (ECM) biodegradable nanoscale materials, which can be used as tissue scaffolds because of its similarity with extracellular matrix.

This kind of scaffold makes the cells close close to each other and grows into three dimensional tissue.

Its key factors are mechanical stability, biocompatibility, cell proliferation and cell interaction.

Recently, the interest in nanoscale spinning and melting fibers is enormous. Hills has successfully produced 250 nm homogenous melt spinning sea island superfine fiber and successfully manufactured 300 nm diameter nanotubes by using the island sea molding method, with a thickness of 50-100 nanometers. Hills nanowire fibers can be used to defend chemical weapons, drug release, micron filtration and micron scale hydraulics (hydraulic devices).

In 1991, SumioIjima, the NEC laboratory, successfully developed multi-layer carbon nanotubes, characterized by light weight, high strength, good electrical properties and good heat resistance.

In collaboration with scientists from the NanoTech Research Institute of Dallas University of Dezhou (UTD) and the Commonwealth of Australia scientific and Industrial Research Organization (CSIRO), multi layer carbon nanotubes were added into the spinning process to make yarns with high strength, good toughness, extremely soft, conductive heat pfer.
