Production Practice of the Card A186F with the Stationary Wire Flat GFB-IIIQ

In order to upgrade the performance of the conventional card for better configuration,considering the situation that most of the card cylinders of the second generation fail to be equipped with the stationary wire flat,an approach is made into the card A186F equipped with the stationary wire flat GFB-ⅢQ regarding its installation,caution of application and the process configuration.Highlight is given to the yarn quality before and after the modification plus the related quality index.Analysis is also done to the yarn quality after increse of the rationed card sliver.Conclusion is made that addition of the stationary wire flat to the conventional card can increase the quality of the conventioanlly carded yarn while the combed yarn with better inner quality.Stablizing of the quality can be realized for the card and the promotion of the effiency process with big ration can be gained for the conventional card.The number of the card can be cut down with marked reduction of the production cost after the modification.Selection of the wire flat card must be done considering the situation of the card and other card elements with better process configuration.
