A good meltblown cloth is heavy enough. It looks white rather than transparent. It looks a bit like paper. The thinner the  meltblown cloth , the worse the protective effect. The  melt blown layer  will melt when it encounters fire and will not burn. The melt blown layer has an electrostatic adsorption effect. You can use these to distinguish between true and false. The difference between non-woven fabric and meltblown fabric 1.  Non-woven fabric Non-woven fabrics mostly use polypropylene pellets as raw materials. It is moisture-proof, breathable, flexible, light, and non-combustible. It is easy to decompose, non-toxic and non-irritating, rich in color and low in price. Recyclable and other features. The non-woven fabric has no warp and weft threads, so it is very convenient to cut and sew. Moreover, it i

What is the application field of breathable film composite non-woven fabric | Guidenonwoven.com

  There are many varieties of breathable film composite non-woven fabrics, which are widely used in agriculture, industry, construction and other fields. At present, my country's waterproof and  breathable membrane and  breathable non-woven fabric  industries are facing major development opportunities. In 2018, the industry's output was about 273,400 tons. Enterprises should increase technical  input, rationally use resources, and make up for the shortcomings in production technology and material supply as soon as possible, so as to win more market shares in the waterproof and breathable  membrane market. Hygiene products are the largest market for  SMS composite non-woven fabrics . The most important factor for the rapid development of SMS materials worldwide is to cater to the rapid growth and urgent  needs of disposable sanitary products.

  Face masks are generally made of multilayer non-woven fabrics: spunbonded non-woven fabrics or hot rolled non-woven fabrics + meltblown non-woven fabrics + spunbonded non-woven fabrics (SMS structure). The  middle M layer  meltblown non-woven fabric  is a kind of non-woven fabric. The main raw material for the production of melt-blown non-woven fabrics is melt-blown grade PP. Its performance  characteristics are high melt index (more than 100 times that of ordinary grade PP), stable fluidity, narrow molecular weight distribution, low ash content, no other product residues, and excellent  silk performance and so on. The fiber produced by the  melt blown cloth factory  process is almost superfine fiber, so the melt blown non-woven fabric has excellent barrier and filtration, air permeability, and oil absorption. It  is widely used in medical protection, sanitary cleaning materials,  filter materials , warm flocs, oil-absorbing materials, battery separators and other fields. Features of
