摘　　要：In this paper,the critical zone concept is proposed onthe mechanism of tensile breakage of nonwoven.Thestrength of critical zone of nonwoven is taken to be allthe pull-out force of bridging fibers from nonwoven,which are related to content of adhesive.The strength ofnonwoven is determined by the strength of critical zone.Based on these,a mathematical model of nonwovenstrength was derived.In this paper, the critical zone concept is proposed on the mechanism of tensile breakage of nonwoven. The strength of critical zone of nonwoven is taken to be all the pull - out force of bridging fibers from nonwoven, which are related to content of adhesive. The strength of nonwoven is determined by the strength of critical zone. Based on these, a mathematical model of nonwoven strength was derived.
