A data mining approach to process optimization without an explicit
To overcome this problem, we use a data mining approach. First, a partial least squares model is used to reduce the dimensionality of the process and quality variables. Then the process settings that yield the best output are identified by sequentially partitioning the reduced process variable space using a rule induction method.

Textile fabrics (woven or knitted) are subjected to strain both lengthwise and widthwise during fabric manufacturing. This strain is released while washing the fabric under relaxed conditions, resulting in a reduction in length and/or width of the fabric which is called shrinkage. Apparel made of such fabrics suffers shrinkage after washing and go out of fit.
