- a process for the production 'of arti ficial thread by the copper oxide ammonia process comprising recirculating a precipitating liquidcontaining copper oxide amq q s equivalent to one-third of the total quan- Q monia, Withdraivinga'portion of said liquid,
- a process' for the production of artificial thread by. the" c opper oxide ammonia process, comprising recirculating a prec'ipitating liquid containingcopperuoxide a n'- monia, removing about a third of" said 'pre- P cipitating liquid, treating said removed third to remove ammonia, substantially equivalent to "the amount dissolved by a" single circulation ofthe precipitating liquid,
- separating the bomber precipitatedfduri'ng j" ficial thread by the copper oxide ammonia process comprising recirculating a precipitating liquid containing copper oxide ammonia, Withdrawing a portion of said liquid containing more copper oxide and ammoniathan is dissolved in said liquid during a single circulation of the same, heating said portion to remove sufiicient; ammonia to reduce the remainder of said portion to a concentration such that Whenit is'returned tothe're circulating liquid the mixture Will have the desired concentration separatingthe copper precipitatedf during the heating, 7 s and re-introducing said treated portion to the re-circulating liquid.
