The physical properties of woven fabrics such as pilling. crease recovery, shrinkage, heal resistance and breaking strength were investigated for the seven kinds of Mikulon blended yam fabrics. It was considered about the effects of fiber characteristics and fabric structure to the fabric performance. Also it was studies on the relationships among flexiblity, crease recovery and breaking strength by some of the basic statistical methods. The decrease in crease recovery and breaking strength was very close proportion to the flexing cycles. Good correlation was found between the percent change in breaking strength and in crease recovery. The fabrics blended with viscose staple fibers have made the more decrease in breaking strength to the flexing cycles than those blended with cotton fibers. Also it was found that the cotton blended fabrics have made the higher percent loss in crease recovery than those in breaking strength .
