The quality values of the yarn have been checked by Uster Tester apparatus accepted as in world standards. In the tests the values like non-smoothliness, fine-thick point, neps, hairines in yarn have been seen. These controls have been made in all faces of the production, and our firm, which is aware of the quality, has continuously benn updating its machines.    
  Another point we closely deal with is to produce yarn with no number variation. To do this kops and bobbins have been checked periodically by strips on automatic spinning wheel, and by wick reels on manuel spinning wheel.   
  We should also check the quality of the yarn in concrete by winding it on a black cartela.  
  In all levels of the production the results of the tests have been checked daily by laboratory autorities and enterprise managing personnel. If there have been any faults solutions are found.
