Application practice of the electret drum filter in eliminating the foggy yarn in the cotton mill;

The present situation and developing tendency in preventing and eliminating “foggy yarn” in the cotton mill;

The foggy yarn caused by the airborne particles makes a negative affect on the quality of the textile products in China.

Research on Harnessing Coal-dust Stained Yarn with Hydrodynamic Ultrasonic Water-jet Room;

Discussion on Special Type Electret Air Filter of Coal-dust Stained Yarn;

5))contained in the air,the coal-dust stained yarn is effectively eleminated.

Electric blackboard simulation based on gray variety analysis of yarn defects;

Practice of Reducing Acrylic Wool Blended Knitting Yarn Defects

In order to clear harmful yarn defects reasonably,clearing parameters are chosen and tested with USTER CLASSIMAT Ⅱyarn faults grader to enhance correct-cut rate and clearing efficiency,The optimized clearing parameters control yarn defects of 100 km below 5 pieces,keep production efficiency at 75%.

Analysis and Control of 100km Yarn Defects;

Parameters Setting of Electronic Clearer and Yarn Defects Control of Cloth Surface;

The result shows that,on normal ring spinning frame,using left diagonal yarn path can reduce yarn hairiness,enhance yarn strength,improve yarn evenness and lower yarn defects evidently than using conventional yarn path;nevertheless,on compact spinning frame,yarn quality is not sensitive to the change of yarn path.

Comparison between capacitor-type and photoelectric type yarn evenness meter in measuring normal yarn faults

Analysis and control of yarn faults caused by spinning equipment factors

8tex(32s×70D),the selection of the raw material,yarn faults appearing easily in producing and the technical measures of treatment on the traditional ring frame.
