Abstract

The invention is concerned with a process for the production of cellulose molded bodies exhibiting high brightness, which is characterized by a combination of the steps of bleaching pulp using a bleaching agent, provided that the bleaching agent does not contain chlorine or any chlorine compound, dissolving the pulp bleached using the bleaching agent in an aqueous tertiary amine-oxide, a moldable cellulose solution being obtained, and processing the moldable cellulose solution into molded bodies.

Claims

exact text as granted — not AI-modified
1 . A process for the production of cellulose fibres exhibiting high brightness, characterized by the combination of steps of 
 bleaching pulp using a bleaching agent, provided that said bleaching agent does not contain chlorine or any chlorine compound,    dissolving said pulp bleached using said bleaching agent in an aqueous tertiary amine-oxide, a mouldable cellulose solution being obtained, and    processing said mouldable cellulose solution into fibres.    
     
     
         2 . A process according to  claim 1 , characterized in that said mouldable cellulose solution is processed into fibres according to the dry/wet-spinning process.  
     
     
         3 . A process according to  claim 2 , characterized in that said fibres are bleached using a bleaching agent, provided that said bleaching agent does not contain chlorine or any chlorine compound.  
     
     
         4 . A process according to one of the claims  1  or  2 , characterized in that as said tertiary amine-oxide N-methylmorpholine-N-oxide is used.  
     
     
         5 . Use of a pulp bleached using a bleaching agent for the production of cellulose moulded bodies according to the amine-oxide process, provided that said bleaching agent does not contain chlorine or any chlorine compound.
