Study on Carding Quality of Carding Roller in Rotor Spinning
In order to test the carding quality of different types of carding rollers,the characteris-tics of carding draft of carding roller and classification of carding roller are introduced.The in-fluence of carding roller on carding draft is described in detail from the aspects of spinning box structure,air flow control and carding roller speed.Seven kinds of rack for carding roller are se-lected,and the lyocell fiber with smoother surface and more circular cross section and cotton fi-ber are used in the comparative test,the reliability of the fiber damage degree is verified by the fiber damage frequency difference analysis method.The results show that the overall quality of cotton yarn basically deteriorates with the decrease of the tooth density of card clothing,except for the G-type carding roller with the smallest tooth density,and the yarn quality is related to the type of carding roller,it is also affected by tooth geometry,surface roughness and its adapt-ability to feeding mechanism,exhaust channel and air flow state in fiber transport channel;the difference of the surface roughness of the rack for card clothing in the carding roller has little effect on the fiber damage,but has great effect on the yarn quality.
