Description of the specific use of Melt blown fabricJun 24, 2021
(1) Medical protection
Because the composite material of Melt blown fabric and spunbond cloth has high hydrostatic pressure resistance, good air permeability and filtering effect, especially the material composited with membrane, it has good barrier performance and filtering efficiency for non-oily particles It can reach more than 99%.
(2) Materials for air filtration
Melt blown fabric are mainly used as composite materials, filter materials, thermal insulation materials, sanitary products, oil-absorbing materials and clean cloths (wiping cloths), battery separators, etc., and are widely used in medical and health, automotive industry, filter materials, and environmental protection. And other fields.
(3) Materials for liquid filtration
Melt blown fabric can also be used as a liquid filter material, which can filter particles with a particle size of 0.22~10um. Such as bacteria, blood and macromolecular substances. It is mainly used in the filtration of photosensitive resists in the electronics industry, the filtration of pharmaceutical, biological, and synthetic plasma products in the pharmaceutical industry, the filtration of beverages, beer and Tangjiang in the food industry, the fine filtration of electroplating solutions, the filtration of water purification in water plants, and the purification and filtration of tap water. Click the water hydrogen production device, environmental wastewater filtration, etc.
(4) Thermal insulation materials
Melt blown fabric have the characteristics of large specific surface area, small voids, and high porosity. For example, the meltblown nonwoven fiber with an average diameter of 3um [equivalent to an average fiber linear density of 0.0638dtex (fineness of 0.058 denier)] has a variable area of 14617cm2/g, and the average diameter is 15.3um [equivalent to average fiber The specific surface area of the spunbonded nonwoven fiber with a linear density of 1.65dtex (1.5 denier) is only 2883cm2/g.
(5) Oil-absorbing material
Because PP fiber has good hydrophobicity and lipophilicity, low density (0.91g/cm3), low water absorption (0.01%), and moisture regain of 0.05%, it has stable chemical characteristics such as insoluble in oil and acid and alkali resistance. Very good oil-absorbing material. The oil absorption of the meltblown nonwoven fabric produced from PP raw materials is 15-17 times its own weight, and the water absorption is 0.71~1 times its own weight. It has the characteristics of fast oil absorption, long-term floating on the water surface after oil absorption, and reusability. It is currently the most commonly used oil-absorbing material.
(6) Wipe and industrial materials
Melt blown fabric is also an excellent wiping material, which can be used for cleaning and wiping precision instruments and equipment, and can also be used as a wiping cloth for household life. In order to prevent the fiber from falling off during use and affect the use, low temperature hot rolling process is often used to increase the surface strength of the melt blown cloth.
