Soft sensor model of shrinkage of rubber blanket preshrinking machine

There are many complex factors influencing shrinking effect of rubber blanket preshrinking machine in preshrinking processes of dyeing and finishing.It is very difficult to realize online prediction of shrinkage and accurate and quantitative design of preshrinking technology.Based on the shrinking mechanism and analysis of deformation of the rubber blanket,a soft sensor model of relationship between shrinkage and extrusion pressure which is the biggest impact factor is built.The experimental results indicate that the relative errors of shrinkage calculated by the soft sensor model are lower than 8%,and the mean absolute percentage error is 5.104 1%.The model is feasible and efficient,providing a guide for online prediction of shrinkage and designing accurate and quantitative desing of preshrinking technology.
