Quality of Yarns Produced by Japanese Open-End BD-200 Spinning Machines and of Final Products
Yarns produced by Japanese Open-end BD-200 spinning machines give these major advantages: (1) They are somewhat stronger than yarns spun by Czecho BD-200's. (2) They are almost as strong as yarns spun by ring spinning machines. This strength is obtainable without raising the cost of raw cotton if the right fore-spinning processes and spinning conditions are used. (3) They have maximum strength ...
متن کاملSpinning eggs—which end will rise?
We examine the spinning behavior of egg-shaped axisymmetric bodies whose cross sections are described by several oval curves similar to real eggs with thin and fat ends. We use the gyroscopic balance condition of Moffatt and Shimomura and analyze the slip velocity of the bodies at the point of contact as a function of u, the angle between the axis of symmetry and the vertical axis, and find the...
متن کاملRapidly Spinning Black Holes in Quasars: An Open Question
Wang et al. (2006) estimated an average radiative efficiency of 30%–35% for quasars at moderate redshift. We find that their method is not independent of quasar lifetimes and thus that quasars do not necessarily have such high efficiencies. Nonetheless, it is possible to derive interrelated constraints on quasar lifetimes, Eddington ratios, and radiative efficiencies of supermassive black holes...
متن کاملEstimation of Open-End Cotton Yarn Strenght from Fiber Physical Characteristics
Physical properties of cotton yarns are affected by the characteristics of cotton fibers such as fineness, length, maturity and strength. This relationship has been worked out by means of multivariable regression and stepwise method for an open-end spun (NeC 20) cotton yarn. Moreover, with the help of linear programming, it was made possible to determine the percentage of different cottons in t...
