LEADING EDGE OF CARDING TAKER-IN CLOTHING WITH VARIABLE ANGLE OF INCLINATION IN COTTON SPINNING (Pages : 18 - 23)

The card is regarded as the heart of the spinning mill because of its immense significance for quality of ultimate yarn. Quality of carding process is mainly determined by the parameters of card clothings. The angle of inclination of leading edge of the taker- in clothing is one of the most important parameters that determines effectiveness of various function. The review of relevant studies demonstrates that optimum values of this angle are different for different functions which are sometimes conflicting. For example, if theoretically combing or of fiber materials is performed with greater angle of inclination of teeth, then throwing of impurities and transfer of fibres from the taker-in to the cylinder take place better with less inclined teeth. In practice, the same teeth of the taker-in with a definite angle of inclination perform both types of functions. This article reveals and sorts out these conflicting aspects in the region of the taker-in and comes out with the suggestion of a new type of taker-in clothing with variable angle of inclination along its leading edge. Such profile of the taker- in must provides better interaction of fibre and the teeth thanks to simultaneous possession of higher penetrating capacity of teeth and fulfillment of conditions of stable equilibrium.Download
