Breaking through the "stuck neck" nanofiber macro production technology, Lianrunxiang Surforce has a trick!
What is a true nanofiber membrane.
Nanofiber membrane is a film composed of true nanofibers, in a broad sense, only the diameter of the fiber below 1 micron can be called nanofibers. Therefore, many membrane products on the market are not composed of nanoscale fibers from the source, and naturally they are not real nanofiber membranes.
What are the preparation methods for taking the film on the market.
According to the mechanism of preventing liquid water penetration and water vapor transmission, the commonly used film on the market can be divided into three types: microporous film, non-porous film and two-component film.
At present, the non-porous film on the market is mostly thermoplastic polyurethane (TPU) film, nanofiber film and PTFE film belong to the category of microporous film, and the two-component film is generally composed of pure microporous waterproof permeable film and hydrophilic non-porous film composite, in order to solve the problem first generation of PTFE laminate fabric easy to permeate the water , but the permeability of the film is weakened.
From the point of view of the preparation process, TPU film is the use of the solution through two different processes of casting film and blowing film to reach the set thickness, and finally cooling to form.
PTFE film is processed into film by bidirectional tension film is carried out transverse/longitudinal bidirectional tension, maintaining the tension state for appropriate heat setting or cold treatment.
The film forming process of Surforce nanofiber film is different from the traditional film forming process, which is realized by spinning forming technology.
Breaking through the "stuck neck" nanofiber macro production technology, Lianrunxiang Surforce has a trick!Nanofiber macro production technology of "stuck neck"
Macro production of nanofibers has always been known as the industrys "stuck neck" technical problems, many nanofiber film research only stays in the laboratory stage, there is no ability to large-scale, stable mass production, and foreign companies that can achieve nanofiber mass production are mostly concentrated in the field of filtration. China will nano fiber macro production and application system establishment, listed as the next 10 years development planning, the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the "2025 breakthrough nano fiber macro production technology" guidance, and in the "Green Paper on technological innovation in key areas of Chinas manufacturing industry" pointed out that "nano fiber macro production of this new technology development route".

Surforce nanofiber membrane - Break through the industry mass production technology bottleneck, to achieve macro production!
According to the "Guidance on the high-quality Development of chemical fiber Industry" jointly issued by the Ministry of Industry and the National Development and Reform Commission, the "Top Ten Industries" Action Plan for 2022 issued by the General Office of the Shandong Provincial Government, and the "Green Paper on Technological Innovation in Key Areas of Chinas Manufacturing Industry - Technology Roadmap (2019)", Lianrunxiang nanofiber material project was launched. The R & D team closely follows the national policy layout, actively undertakes the national Advanced functional fiber center scientific research project, successfully breaks through the bottleneck of nanofiber mass production and preparation technology, solves the problem of industrial application, and successfully introduces Surforce nanofiber materials to the market!
Nanofiber membrane has a wide range of applications.
The breakthrough in the mass production of nanofiber film solves the difficulty of stable mass production of nanofiber film for clothing, fills the gap in the macro production of domestic nanofiber film, broadens the market segment of membrane products in clothing, solves the market problem of "poor permeability", "no elasticity," and "balloon effect" of coated clothing, enhances the value of the industrial chain, and creates new economic growth points.
In addition, nanofibers have many characteristics, such as high porosity, large specific surface area, high aspect ratio, high surface energy and activity, as well as some special nanomaterial properties, such as electrical, magnetic, optical and other characteristics, can be applied in batteries, medical, beauty, environmental protection, filtration and other fields, to promote the formation of new formats, new models, has a positive significance.
