Effects of fiber cross-sectional shapes on tensile and tearing properties of polyester woven fabrics

Abstract

Breaking load and elongation, and tearing load properties of two type fabrics (plain and twill) woven from polyester fibers having round, hollow round, trilobal and hollow trilobal cross-sectional shapes were investigated. The fabrics produced from full fibers had higher breaking elongation and tearing load values but generally lower breaking load values than the fabrics produced from hollow fibers. The highest breaking load value was obtained in twill fabric woven from filaments having hollow round cross-sectional shape, while the highest tearing load value was obtained in twill fabric woven from filaments having round cross-sectional shape. The fabrics constituting filaments with round cross-sectional shapes had the highest breaking elongation values It was concluded that the effect of fiber cross-sectional shape on breaking strength and on tearing strength differed from each other.
