w 2. Application in the field of medical and health care: made of melt-blown cloth dust mouth breathing resistance is small, not short, dust control efficiency is as high as 99%, widely used in hospitals, food processing, mining and other workplace to dust, prevent bacteria with anti-inflammatory analgesic membrane made of product after special treatment, permeability is good, non-toxic side effects, easy to use, and spun-bonded fabric of SMS composite products are widely used in the production of sanitary products such as surgical clothes. 3. Liquid filtration materials and battery diaphragm: polypropylene melt-blown filter cloth used in acidic and alkaline liquid, oil, oil has very excellent performance, such as the battery industry at home and abroad has been regarded as a good membrane material, and has been widely used, not only reduces the cost of battery, simplifies the process, and greatly reduce the weight and volume of the battery. 4. Oil absorbent materials and industrial wipes: polypropylene melt spraying cloth made of various oil absorbent materials, oil absorption up to the weight of 14-15 times, widely used in environmental engineering, oil-water separation engineering, in addition, in industrial production, can be used as oil and dust clean materials. These applications give full play to the characteristics of polypropylene and the adsorbability of the ultrafine fiber produced by melting and spraying. 5. Thermal materials: the average diameter of fusion-sprayed ultrafine fiber is between 0.5 ~ 5m, the specific surface area is large, and a large number of fine pores are formed in the cloth with high porosity. There is a large amount of air stored in this structure, which can effectively prevent heat loss and has excellent thermal insulation. It is widely used in the production of clothing and various thermal insulation materials. Such as leather jacket, ski shirt, cold clothing, cotton village cloth, with light, warm, moisture absorption, good permeability, no mildew and other advantages.
