Non-flammable polyester (PET) fiber
Non-flammable PET fiber production
  • Share

VLADPOLYTEX is working on the commercial production of nonwoven materials from non-flammable PET fiber modified with carbon materials using a crazing technology. The company manufactures the materials from recycled plastic bottles without emitting dust particles. The materials are resistant to mold and rodents, are environmentally friendly (do not produce toxic gases), exhibit nearly 100 percent elasticity, and can be used for at least 50 years.

  • Principle of crazing technology in PET fiber production

    The structural transition leading to the compression of the fibers and reduction of the effective pore diameter. The fixation of fire-retardant molecules in the nanocavities between the polyethylene terephthalate fibers.

Polyethylene terephthalate (i.e., PET, PETP, or polyester) is a thermoplastic polymer. It is one of the most widely used polyester plastics. PET can be used to produce polyfiber by using a hot melt process. VLADPOLYTEX produces non-flammable polyfiber products, which is achieved by modifying PET fibers with fire-retardant particles that inhibit combustion. The material is modified using a technology called polymer crazing. In polymer crazing, stress deformation is used to introduce nanocavities into a polymer structure; these cavities can subsequently be filled with the fire retardant. Crazing is effective in obtaining porous materials with a final pore size of up to 90 nanometers, a total pore content of up to 60 percent, and a specific surface area exceeding 100 square meters per gram. The crazing technology accommodates the rapid and successful introduction of various modifying additives, such as fire retardants, into the polymer structure.

Cooperation with RUSNANO

The Visual Science Company has cooperated with the RUSNANO Group since 2008, creating a wide range of high quality graphic information materials. Various infographics have been designed to demonstrate the technologies developed and implemented by RUSNANO project companies. The aim of each project is to demonstrate the principle of technology, nanotechnological components of the project and the advantages of the chosen solution compared with analogues.

The work of Visual Science is carried out in a single sheet or slide format. The modular structure of the infographics makes it possible to use it both as a whole piece or as separate components, which is convenient for preparing website illustrations or project reports or publications. Thus one material helps to solve almost all the issues with illustrating the information about the project.

The target audience for these graphics includes professionals in relevant areas, and a wide range of specialists in different fields without a technical background. Scientific accuracy, combined with the optimum degree of generalization allow for communicating equally effectively with target audiences with different background.

All the graphics have been used by the RUSNANO Group for 5 years or more. As usual, the feature of the Visual Science workflow includes the entire spectrum of tasks ranging from analyzing the scientific literature of the project to the preparation of the final graphics on the company’s side that allows saving valuable time of our customers.

Based on our experience, we highly recommend Visual Science as a reliable, trustworthy partner with excellent scientific, artistic and organisational expertise.
