Antistatic fibrous material and method for manufacturing same

Abstract

An antistatic fibrous material manufactured by treating a natural and/or regenerated fibrous material with both (1) at least one di-halogeno-s-triazine that has at least one hydrophilic group, and (2) urea, thiourea, and an amino acid, or a combination of two or more of said three compounds. The treatment includes the following steps: (a) saturating a natural and/or regenerated fibrous material with a solution that contains (1) a di-halogeno-s-triazine having at least one hydrophilic group and (2) urea, thiourea, and an amino acid, or a combination of two or more of said three compounds (b) heating said saturated material at 30° C.-60° C., and (c) heating said saturated material at 60° C.-90° C.

1 . An antistatic fibrous material manufactured by treating a natural and/or regenerated fibrous material with both (1) at least one di-halogeno-s-triazine that has at least one hydrophilic group, and (2 urea, thiourea, and an amino acid, or a combination of two or more of said three compounds. 
   
   
       2 . An antistatic fibrous material of  claim 1 , but wherein said treatment includes the following subsequent steps;
 a) Saturating a natural and/or regenerated fibrous material with a solution that contains (1) a di-halogeno-s-triazine having at least one hydrophilic group and (2) urea, thiourea, and an amino acid, or a combination of two or more of said three compounds;   b) Heating said saturated material at 30° C.-60° C.; and   c) Heating said saturated material at 60° C.-90° C.   
   
   
       3 . An antistatic fibrous material of  claim 1 , but wherein said treating includes the following subsequent steps;
 a) Saturating a natural and/or regenerated fibrous material with a first solution that contains at least one di-halogeno-s-triazine that has at least one hydrophilic group;   b) Heating said saturated material at 30° C.-60° C.;   c) Saturating the natural and/or regenerated fibrous material with a second solution that contains urea, thiourea, and an amino acid, or a combination of two or more of said three compounds,   d) Heating said second saturated material at 60° C.-90° C.   
   
   
       4 . An antistatic fibrous material of  claim 1 , but wherein said di-halogeno-s-triazine is 2,6-dihalogeno-4-Y-1,3,5-triazine of the formula (1) [but wherein X is a halogen atom selected from Cl, Br, or F]; and Y is —OM [but wherein M is selected from Na, K, Li, and Mg], or arylamino, aryloxy, arylmercapto, alkylamino, alkoxy, alkylthio, triazinilamino, triaziniloxy, or triazinilthio that has at least one substitute selected from —SO 3 M, —COOM, —OM, or —SM [but wherein M is selected from Na, K, Li, and Mg]. 
     
       
         
         
             
             
         
       
     
   
   
       5 . An antistatic fibrous material of  claim 3 , but wherein said 2,6-dihalogeno-4-Y-1,3,5-triazine is 2,6-dichloro-4-Y-1,3,5-triazine. 
   
   
       6 . An antistatic fibrous material of  claim 1 , but wherein said natural and/or regenerated fibrous material is silk, wool, cotton, linen, viscose rayon, Cuprammonium-Rayon, lyocell, or Tencel, or any two or more of said materials. 
   
   
       7 . An antistatic fibrous material of  claim 1 , but wherein said natural and/or regenerated fibrous material is in the form of a staple fiber, filament, thread, textile, or nonwoven cloth.
