Abstract:
Provided are a multilayer nonwoven fabric having both high water resistance and antistatic properties despite no films being layered therein, a method for producing the multilayer nonwoven fabric, and a protective garment using the multilayer nonwoven fabric. One surface of the multilayer nonwoven fabric is formed from fibers comprising a polyolefin resin and has a spunbond nonwoven fabric layer A1 containing at least a phosphate ester arranged thereon, the other surface has arranged thereon a spunbond nonwoven fabric layer A2 formed from fibers comprising a polyolefin resin, and a meltblown nonwoven fabric layer B formed from at least one layer of fibers comprising a polyolefin resin is arranged between the spunbond nonwoven fabric layer A1 and the spunbond nonwoven fabric layer A2. The ratio (tA1/tA2) of the thickness (tA1) of the spunbond nonwoven fabric layer A1 to the thickness (tA2) of the spunbond nonwoven fabric layer A2 in a non-fused section of the multilayer nonwoven fabric is 1.5-3.0.
