THE  IDENTIFICATION  OF  ARTIFICIAL  SILKS  ESPE- 
CIALLY PREPARED  FOR  THE  PRACTICAL  MILL 
MAN  AND  DYER/ 
By  Louis  J.  Matos,  Ph.D. 
Owing  to  the  constantly  increasing  use  of  artificial  silks  and  the 
consequent  confusion  arising  in  dye-houses  and  silk  mills  generally, 
due  to  the  occasional,  though  unintentional,  mixing  of  lots,  it  becomes 
a  matter  of  some  importance  for  the  dyer  or  manager  to  be  able  to 
identify  with  certainty  the  several  important  kinds  of  artificial  silks 
on  the  market. 
Where  a  dyer  goes  on  from  day  to  day  with  his  work,  and  on 
one  kind  of  silk,  it  is  a  matter  of  some  consequence  when  he  finds 
himself  confronted  with  the  problem  of  dyeing  a  new  lot  of  different 
kind  of  silk  that  does  not  come  out  as  expected,  or  which  seems  to 
offer  difficulties  during  the  dyeing. 
Many  instances  are  familiar  to  dyers  where  lots  of  mixed  artificial 
silk  have  been  sent  to  the  dye-house,  and  inequality  in  the  dyeing  was
