Force condition in tearing fabric was ana鄄 lyzed,tearing strength of fabricwas tested in different weft density,weft strength,weft count and fabric texture by using trapezoidal method. Theresult showsthatfabrictearingstrengthinweftdirectionisincreasedwithweftdensity increase. When theweft density reaches certain value,tearing strength inweft direction becometo reduce. Fabrictearing strength in weft direction is increasedwithweft strengthincrease. Thetearing strengthoffabricwiththe samematerial andtight鄄 ness are increasedwithweftcountincrease. Whentheotherconditionsaresame,fabricwefttearingstrengthisincreased with warp float length increase. It is pointed out that it is helpful to improvefabric design level by analyzing thefactors of effecting fabric tearing strength in weft direction. 摇 摇 Key Words摇 Trapezoidal Method,Weft
