ABSTRACT
Fiber to yarn conversion process for staple natural fiber like cotton is complex in nature. This is due to the interrelated multivariate relationship, which is nonlinear in nature present between highly variable characteristics natural fiber and yarn properties. Thereby task of producing yarn with precise quality and cost, becomes utmost difficult for the industry mainly rely on human expertise based decision-making. Exercise for optimisation of yarn quality, cost and process parameters starts with precise selection of raw material, a maximum shareholder on yarn quality and cost and then remain focused on desired state of process control to yield maximum beneficiary fiber properties into output yarn till the end. Thus spinning technologist, a decision maker has to take care of two major tasks for successful yarn engineering, viz; selection of suitable quality raw materials at minimum cost and optimisation of process parameters. Introduction of automated as well as precise testing and production techniques and development of software for linear programing and EFS together have realized a long-cherished dream of spinning technologists on real ground.
