摘要
Provided are a melt blown (MB) nonwoven fabric, a laminate using the same, a method of producing a melt blown nonwoven fabric as well as a melt blowing apparatus. A melt blowing apparatus 100 includes a die 10 configured to discharge a resin melt 42 with an accompanying jet to give fiber materials, a hollow cover 20, and a collector 60. The fiber materials 50 from the die 10 are heated to a temperature equal to or higher than a crystallization temperature of the crystalline thermoplastic resin inside the hollow cover 20 and collected on a collecting surface 62 of the collector 60. The hollow cover 20 and the collector 60 are separated by a distance of 5 cm or longer between a lower edge 28 of the hollow cover 20 and the collecting surface 62 in a line extending downwardly from the nozzle holes 12 in a vertical direction.
