摘要
作者将织物的轧液过程作为一个动力学过程来考虑,研究了其轧液机理,分析了各种因素对轧液效果的影响。并且发现流体动压力是构成轧辊阻力矩的主要成分,它随织物运行速度增大而增大。还阐明前孔区内流体的渗透速度梯度是引起织物拉伸变形的原因。文章还给出了如织物渗透系数等重要参数的计算方法,并提出了降低轧余率以及减少织物拉伸损伤的设想。
In this paper,the mechanism of fluid removal from fabrics by squeezing was investigated dynamically.Various factors which affected the results of squeezing were analysed In an all-round way.It was also found that the dynamic pressure of fluid,which increased with the process velocity of fabrics,formed the resistant moment of the rollers of mangle,and that the gradient of the seepage velocity of stretching of the fabrics processed.The methods for calculating some important parameters of fabrics (such as permeability coefficients),and some proposals for lowering the take-up and lessening the fabric damage were prasented as well.
