摘　　要：In this paper,an equation expressing relationship between trapezoid tear strength and fabrictensile properties,weave texture and geomitry of specimen was studied.It could be used to predicttrapezoid tear strength for uncoated fabrics well,and also for coated fabrics if multipling a stressconcentration coefficient.The four tear test standard methods(single-rip,double-rip,wing-ripand trapezoid tear)have been adopted to measure the tear strength of fifteen coated fabrics whichwere used for architecture and gencral industrial purposes and the nine corresponding uncoatedfabrics respectively.Analysis and comparison of experimental results showed that there are an ex-cellent correlation between each two methods with the four tear parameters respectively and a goodconsistency of the order of the tear strength for different samples.In addition,the experimental results showed that a good correlation exists between the tenslieproperties and tear strength of coated and uncoated fabrics.In this paper,an equation expressing relationship between trapezoid tear strength and fabric tensile properties,weave texture and geomitry of specimen was studied.It could be used to predict trapezoid tear strength for uncoated fabrics well,and also for coated fabrics if multipling a stress concentration coefficient.The four tear test standard methods(single-rip,double-rip,wing-rip and trapezoid tear)have been adopted to measure the tear strength of fifteen coated fabrics which were used for architecture and gencral industrial purposes and the nine corresponding uncoated fabrics respectively.Analysis and comparison of experimental results showed that there are an ex- cellent correlation between each two methods with the four tear parameters respectively and a good consistency of the order of the tear strength for different samples.
