Non-woven fabrics, also known as “non-woven fabrics”, refer to fabrics that do not need to be spun and weaving. The non-woven fabric industry originated in Europe and the United States in the 1950s and was introduced to my country for industrial production in the late 1970s. During the development process Among them, non-woven fabrics have evolved a variety of processes such as spunbonding, needle punching, spunlace, chemical bonding, thermal bonding, airlaid, wet, and meltblown.
Because it is the core material of medical protective masks, meltblown cloth is well-known to the public, and it is even hard to find a cloth when the epidemic is serious. However, before the epidemic, meltblown fabrics were relatively niche in the non-woven fabric industry. The data shows that the output of spunbond non-woven fabrics in 2019 was 3.0943 million tons, accounting for 49.80% of the total output of non-woven fabrics. During the same period, the output of melt-blown non-woven fabrics accounted for only 1.07% of the total non-woven fabrics. .
It is reported that since the beginning of the 21st century, my country’s non-woven technology has made great progress and consumer demand has continued to grow. Non-woven equipment manufacturing, raw material production and product processing have formed a complete supply chain system, especially under the influence of this year’s epidemic. The world’s demand for non-woven fabrics and supervision efforts have greatly increased, which has greatly promoted the production of domestic antibacterial non-woven materials.
Since the outbreak of the new crown epidemic in 2020, the non-woven market has been hot, and many types are still in short supply. The demand for non-woven products such as spunlace and super fiber used in the production of fast-moving consumer goods is still increasing. As a result, foreign demand for non-woven fabrics has skyrocketed, and foreign sources are in short supply. There are also many non-woven fabric purchase orders to China. The whole market is expected to continue until the end of this year, but the market in 2021 and beyond cannot be rashly concluded. After all, in the absence of an epidemic, the non-woven fabric industry directly related to the epidemic only meets the normal consumption of the daily medical care industry. After this epidemic, consumers’ consumption behaviors, habits and consciousness will change, and the non-woven fabrics of daily fast-moving varieties will have a tendency to continue. The epidemic catalyzes the demand for spunlace and meltblown non-woven fabrics. In the future, the government and hospitals will also increase the reserves of protective equipment. Residents’ demand for disinfection wipes and other cleaning products is also expected to increase. The epidemic will catalyze the growth of demand for non-woven fabrics. In the future, the growth in demand for downstream medical, personal hygiene and healthcare products will drive the continuous growth of non-woven fabrics.
The raw material used in the production of spunbond non-woven fabric is high-melt index polypropylene, which is evenly mixed with calcium carbonate filler masterbatch, and then enters the screw extruder from the hopper to be extruded and melted, then enters the continuous pre-filter, and then enters the spinning box. . The melt enters the spinning head through the metering pump, and is accurately metered by the metering pump. The melt is quantitatively delivered to the spinneret, and a continuous stream of melt is formed through the spinneret hole, that is, the nascent fiber. The nascent fiber is then cooled by the quench air and drawn by the airflow to form a filament bundle. The filament bundles are oscillated back and forth by the oscillating roller, and are evenly laid on the running netting curtain to form a fiber web.
Based on the advantages of non-woven fabric production technology and product performance, the non-woven fabric industry has developed rapidly in my country. At present, China has become the world’s largest non-woven fabric producer and consumer.
