Cut and abrasion resistant fibrous structure

Abstract

The invention relates to a fibrous structure comprising at least one non composite p-aramid strand and at least one nylon strand maintained in a parallel relationship to each other, the non composite para-aramid strand being present in the material in an amount ranging from about 20% to 99.9% by weight, relative to the weight of the structure. The invention also relates to a process to manufacture such structure and to high cut and abrasion resistant protective clothing made of this structure like gloves, aprons and sleeves.

1 . Fibrous structure comprising at least one non composite para-aramid strand and at least one nylon strand maintained in a parallel relationship to each other, the non composite para-aramid strand being present in the structure in an amount ranging from about 20% to 99.9% by weight, relative to the weight of the structure.  
     
     
         2 . Structure of  claim 1 , wherein the non composite para-aramid strand is present in an amount ranging from about 30% to about 70% by weight, and the nylon strand is present in an amount ranging from about 30% to about 70% by weight, relative to the weight of the structure.  
     
     
         3 . Structure of  claim 1 , wherein the nylon strand is a textured strand.  
     
     
         4 . Process to manufacture the fibrous structure of  claim 1 , comprising the step of processing a non composite para-aramid strand and nylon strand in a parallel relationship to each other.  
     
     
         5 . Process of  claim 4 , wherein the processing includes knitting, weaving, unidirectionally laying down or combining the strands with a binding matrix to form a nonwoven.  
     
     
         6 . Process of  claim 5 , wherein processing is knitting.  
     
     
         7 . High cut and abrasion resistant protective clothing made of the fibrous structure of  claim 1 .  
     
     
         8 . High cut and abrasion resistant gloves made of the fibrous structure of  claim 1 .  
     
     
         9 . High cut and abrasion resistant sleeve made of the fibrous structure of  claim 1 .  
     
     
         10 . High cut and abrasion resistant apron made of the fibrous structure of  claim 1 .  
     
     
         11 . Process for providing a fibrous structure having high cut and abrasion resistance, comprising: 
 a) providing strands of at least one non composite para-aramid strand and at least one nylon strand,    b) feeding the strands into a knitting or weaving machine without prior assembly,    c) knitting or weaving a fibrous structure without changing the order in which the strands are fed into the machine, the strands being maintained in a parallel relationship to each other during the whole knitting or weaving process.    
     
     
         12 . Structure of  claim 1 , showing a combined normalized index CTPCPI.N, equal or greater than 80 g/mm and an abrasion resistance, measured according to EN 388, equal or greater than 1000 cycles.
