On the Effect of Spinning Method upon the Creep and Other Mechanical Properties of Viscose Rayon:Part 1 : On the Effect of Stretch

概要

論文の詳細を見る
The object of the study is to find the effect of spinning methods, especially the degree of stretch at spinning, upon the creep and mechanical properties, measured by tension and creep tests, of viscose rayon.<BR>The results obtained by the experiments using test pieces, stretched respectively by 11, 31 and 70% are as follows : <BR>The maximum elongation, relaxation elongation and creep constant decrease with an increase of the stretch, but the elastic elongation at yield point is little affected by the difference of the amouns of the stretch.<BR>The greater the stretch, the greater the modules of elasticity, yield stress, second modules of elasticity, tensile strength, relaxation time and elasticity rate.
