The great majority of textile industries develop their fab-rics based only on the empirical experience of their techni-cal body of collaborators and/or through trial and error. This process generates a high cost, product losses and requires an excessively long time, occupying production machines, using raw materials, products/consumables, water and energy, often unnecessarily. The knit fabrics produced with cotton fiber are ideal for use directly on the skin, principally due to the physical prop-erties of high elasticity and softness. However, these cotton fabrics are susceptible to dimensional changes, i.e. they have low dimensional stability. The correct adjustment of the production parameters prevents these problems, pro-viding cotton knit fabrics which hang perfectly on the body without causing discomfort to the person wearing the gar-ment. Dimensional stability means that the fabric maintains the dimensions with which it was manufactured, without changing with use. * In general, the dimensional properties of a fabric are the subject of research and planning before a piece of fabric is produced, aiming to obtain a dimensionally stable fabric. The search for dimensional control of cotton knit fab-rics dates back to the beginning of the 20 th century when the first mathematical model was put forward by Chamber-lain [1], who sought to describe the configuration of the loop of a knit fabric. Since then, other researchers [2–18] have developed important studies which conceptualize, define and formulate mathematically the dimensional behavior of knit fabrics. There are variables which directly influence the behav-ior of a knit fabric when it is processed or when it attains Abstract Cotton fiber continues to be the most
