    The purpose of this research is to investigate key factors that affect structure and abrasion resistance of nonwoven fabrics produced from bicomponent fibers. The main objective of producing bicomponent fibers is to develop capabilities not existing in either polymer alone. By this technique, fibers with different cross sectional shape or geometry can be produced. Bicomponent fibers are commonly classified by their fiber cross section structures as side-by-side, sheath-core, islands-in-the-sea and citrus fibers or segmented-pie cross section types. The properties of nonwoven fabrics are primarily determined by the properties of the fibers used to make them. Fundamentally, a fiber property is the response of a fiber to an imposed chemical environment or physical force. In this research three types nonwoven fabrics classified with their fibers (Segmented, Islands in the Sea, and Trilobal) were used to investigate main factors in each group. Visual ranking, optical ranking, and weight loss were investigated to evaluate pill resistance of these fabrics.
