Antistatic dustproof fabric and protective clothing using same

Abstract

A dustproof fabric which includes an antistatic dustproof fabric having excellent antistatic properties, a high air permeability and high-level dustproof properties is provided. The antistatic dustproof fabric includes two or more fiber layers. At least one of the two or more fiber layers is a first fiber layer which contains a nonionic antistatic agent; and at least one of the two or more fiber layers is a second fiber layer which is electrically charged.

1 . An antistatic dust-prevention fabric comprising at least two or more fiber layers, wherein
 at least one layer, which is defined as fiber layer  1 , of these two or more fiber layers comprises a nonionic antistatic agent, and   at least another layer, which is defined as fiber layer  2 , of these two or more fiber layers being in an electrified state.   
     
     
         2 . The antistatic dust-prevention fabric of  claim 1 , wherein the nonionic antistatic agent is a polymer type nonionic antistatic agent. 
     
     
         3 . The antistatic dust-prevention fabric of  claim 1 , having an air permeability of 60 cm 3 /cm 2 /sec or more as measured by the Frazier method according to JIS L1913-2010 and a dust collection efficiency of 50% or more. 
     
     
         4 . The antistatic dust-prevention fabric of  claim 1 , wherein the fiber layer  1  is disposed at least as either of the outermost layers of the antistatic dust-prevention fabric. 
     
     
         5 . Protective clothing comprising the antistatic dust-prevention fabric of  claim 1 . 
     
     
         6 . The protective clothing of  claim 5 , wherein the fiber layer  1  is exposed in at least a portion of either outer surface of the antistatic dust-prevention fabric.
