Melt blown, spunbonded and SMS non-woven fabrics are introduced
BTW (I) : introduction Meltblown non-woven fabric (English: Meltblown) Melt blown non-woven fabric is a kind of microfiber non-woven fabric formed by strong hot air stretching, fiber diameter in about 2 microns, is the most fine in all fibers. Melt blown non-woven fabric has good water tightness and air permeability because of its special structure and raw material polypropylene, high filtration efficiency, collection of bacteria, filtration, heat insulation, warm, insulation, non-toxic, no stimulation and other functions.

The advantages of polypropylene spunbonded non-woven fabric
Polypropylene spunbonded non-woven fabric is a kind of non-woven fabric, which is made of polypropylene as raw material, polymerized into a net after high temperature wire drawing, and then bonded into a cloth by hot rolling method. Due to the simple process, large output, non-toxic and harmless to human body. So it is widely used in various fields, such as health materials.
Non-woven fabric industry development situation
Development of prediction First, the non-woven textile industry has made great development in recent years By 1998, the world's non-woven consumption has reached 2.4 million tons. In 1970, it consumed only 400,000 tons. By 2007, it is expected to consume 4 million tons. Non-woven non-woven manufacturers are mainly concentrated in the United States (accounting for 41% of the world), Western Europe accounts for 30%, Japan accounts for 8%, China's output only accounts for 3.5% of the world, its consumption is 17.5% of the world. By 2007, China's production is expected to account for 7 percent of world production and its consumption will increase to 21 percent.
Spunlaced reinforcement technology and machinery
The non-woven fabric technology of spunlace reinforcement (also known as hydraulic jet method, hydraulic entanglement method, etc.) of fiber mesh started relatively late. It was successfully developed by American companies Dupont and Chicopee in the mid-1970s and realized industrial production in 1985.

The concept and characteristics of nonwovens
Nonwovens (also known as nonwovens), is a new generation of environmental protection materials, with water repellent, breathable, flexible, non-combustion-supporting, non-toxic non-irritating, colorful characteristics. If the material is placed outdoors by natural decomposition, its longest life is only 90 days, placed in the indoor decomposition in 5 years, non-toxic combustion, tasteless, and without any left over substances, so it does not pollute the environment, so environmental protection from this. Suitable for washing and other object points.

Brief introduction of flame retardant chemical fiber
In recent years, the research, development and use of flame retardant fiber gradually increased, and there is a great progress. With the ACCELERATION OF urban modernization, the development OF tourism, transportation industry, and the increase of demand for export, there is a huge potential market for flame retardant fiber series products. According to the survey, the consumption of flame retardant products is mainly distributed in iron and steel casting industry, fire service industry and chemical manufacturing industry. Government units are mainly hospitals, the army and forest fire service teams.
