Using polypropylene (PP) resin as raw material, the fibers formed by high-temperature melt-spinning are thinned under the drafting of high-speed hot air and sprayed onto the receiving device, which is a network-like fiber aggregate formed by self-bonding with residual heat , can be compounded, cut or otherwise made with other materials. The product has compact fiber structure, low resistance and high efficiency. Widely used in mask preparation, air purification, fresh air system, car air conditioning and other special scenarios. The melt-blown cloth produced by Keda Zhite adopts multi-level processing technology and strictly implements the requirements of national and industry standards. Among them, the melt-blown cloth suitable for mask preparation can meet multiple standards such as national standard, American standard, European standard, and Japanese standard, and is suitable for mask preparation under multiple global standards. Air purification meltblown products can reach H14 level, which can meet the requirements of meltblown filter materials under EN1822 standard.
