| 内容記述 | In this paper, it is described that the test yarns do not as a rule obey Amonton=Coulomb's Law and the friction of yarns (mainly nylon yarns) is dependent upon wrapping pressure, yarn speed, and sticking time of yarn to the guide. In the experiment, the pear-skined chromium plated steel guide is adopted as a textile guide. The results obtained in this paper are as follows. (1) The coefficient (μK) of the dynamic friction of nylon yarn approximately obeys the equation, μK=αT^<n-1>_0, where T_0 is initial tension and n and α are frictional constants. According to the experiment, value of n ranges from 0.58 to 0.84, and value of αranges from 0.28 to 0.42. (2) The dynamic friction of nylon yarn reduces slowly at low speeds, then, it increases slowly, or keeps constant, and increases rapidly as yarn speed rises. It could be assumed, therefore, that the region of contact between the yarn and the guide, may deform from plastic to elastic as yarn speed rises in this experimental conditions. (3) According to the experiment, maximum static frictional force of nylon yarn reduces as sticking time to the guide keeps less than about fifteen seconds as a maximum and about ten seconds as a minimum, and it would appear therefore, that the stick of nylon yarn to the guide attains approximately equilibrium state for about ten to fifteen seconds. | |||||||||||
