The flash evaporation method of non-woven fabric has high production technology requirements, difficult research and development of production equipment, complex processing technology, and an irreplaceable position in the fields of personal protection and high-value medical device packaging. It has always been regarded as the “pearl” in the field of new materials for non-woven fabrics and is a key link in realizing China’s vision of a “joint fleet” in the non-woven fabric field. It is gratifying that China has achieved breakthroughs in core technologies and related production and processing technologies have entered the world-class echelon.
The products have effectively filled the domestic gap and partially replaced imported products. However, sustained efforts are still needed in market cultivation and application expansion. In the future, we believe that with the help of China’s mature market environment, strong market resources, and surging market vitality, new breakthroughs will be made in the field of flash evaporation non-woven fabrics in China, striving to catch up with foreign leaders in the coming years.
The Development Status and Facing Situation of Flash Steaming Non woven Fabric Materials in China
The characteristics and application fields of flash evaporation non-woven fabrics
Flash spinning, also known as instantaneous spinning, is a method of forming ultrafine fiber webs. The diameter of the fibers spun is generally between 0.1-10um. This method was successfully developed by DuPont in 1957 and has reached a production scale of 20000 tons/year in the 1980s. In the 1980s, Asahi Kasei Corporation of Japan also began to develop and achieve industrial production, but later the company’s technology was jointly acquired by DuPont and the production line was forced to shut down. So for a long time, this technology has been exclusively monopolized by DuPont, until in recent years, China’s scientific research team has achieved fundamental breakthroughs from scratch.
Flash evaporation non-woven fabric has many characteristics such as light weight, high strength, tear resistance, waterproof and moisture permeability, high barrier, printability, recyclability, and harmless treatment. It combines the advantages of paper, film, and fabric and is widely used in high-value medical device packaging, medical protection, industrial protection, industrial packaging, transportation, construction and home decoration, special printing, and cultural and creative products. In the field of healthcare, this material is the only one that achieves high-performance antiviral and biochemical barrier effects with a single material. It can withstand most current sterilization methods and has an irreplaceable position in the field of personal protection against infectious diseases and high-value medical device sterilization packaging.
It has played an important role in sudden public safety incidents such as SARS and COVID-2019; In the field of industrial protection, this material has light weight, high strength, and high moisture permeability, and can be used for industrial individual protection, special equipment protection, and other fields; In the field of packaging, it has the characteristics of high strength, tear resistance, waterproofing and moisture permeability, and printability. It can be used as a covering material in agriculture, construction, transportation, and other fields. It can also be used as a basic material for home decoration, graphic and pictorial materials, cultural and creative leisure materials, etc.
China’s flash evaporation nonwoven fabric has achieved core technological breakthroughs and commercial mass production
Faced with the numerous product monopolies, technological blockades, and market pressures imposed by overseas enterprises on China, it took decades for China’s flash evaporation nonwoven fabric to achieve a breakthrough in core technology. Enterprises, universities, and research institutes such as Xiamen Dangsheng, Donghua University, and Tianjin University of Technology are tirelessly overcoming difficulties. Currently, they have formed production technologies, processes, and equipment with core independent intellectual property rights, and have successfully achieved the transformation of scientific and technological achievements. As the first domestic enterprise to achieve commercial mass production, Xiamen Dangsheng worked tirelessly day and night to prepare the first flash evaporation spinning high-strength ultra-fine polyethylene fiber bundle in 2016. In 2017, it built a pilot platform, achieved ton level mass production in 2018, and built the first flash evaporation ultra high speed spinning and non-woven fabric industrial production line in China in 2019. In the same year, it achieved commercial mass production. We have achieved remarkable achievements with a span of one year, quickly catching up and breaking through the monopoly situation of overseas multinational enterprises for decades.
The flash evaporation non-woven fabric industry in China is facing a complex and severe environment, with many uncertainties
Due to leading foreign companies leading the field for many years, they have formed advantages in intellectual property, market access, standard certification, trade barriers, brand monopolies, and other aspects. However, the development of China’s flash evaporation non-woven fabric industry is still in its infancy, facing a complex and severe market environment. Any slight mistake can lead to development difficulties, facing not only technological competition, but also comprehensive competition in the market, capital, policies, and other aspects, which requires comprehensive protection from multiple perspectives.
The flash evaporation non-woven fabric market in China urgently needs to be cultivated
On April 12, 2022, the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the Guiding Opinions on the High Quality Development of Industrial Textile Industry, pointing out the need to strengthen the research and development of flash spinning and weaving technology, achieve the industrialization of flash spinning nonwoven technology equipment with an annual output of 3000 tons, and promote its application in medical packaging, protective equipment, printed goods, robot protection, new energy vehicle protection and other products. In addition, this product can also be applied in environmentally friendly industrial packaging, printing labels, agricultural film, cold chain transportation insulation packaging, building enclosure, creative design and other fields.
The maximum application of flash evaporation non-woven fabric is in the medical field, which combines high-performance virus protection and biochemical barrier effects. It accounts for up to 85% of the usage in the medical packaging field. Currently, the medical device market is growing rapidly, and the development potential of sterilization packaging materials is enormous. Protective clothing based on flash evaporation non-woven fabric production combines protection, durability, and comfort, without the problem of suffocation or sweating.
